Current production of oats for grain in Queensland is minor due to unsuitable varieties bred for different climates, and high disease pressure from leaf and stem rust late in the growing season. A range of grain oat breeding lines developed by the Federal University of Rio Grande do Sul in Porto Alegre, Brazil, was screened for leaf rust resistance and subsequently identified as potential grain oat cultivars for sub-tropical Queensland. The evaluation of these grain oat lines from Brazil may provide an opportunity to re-establish oats as a winter grain crop in central and southern Qld and northern NSW. Two replicated trials were established near Toowoomba in Qld and Grafton in NSW to assess grain yield and agronomic characteristics. These trials showed significant differences in grain yield within the set of Brazilian grain oat lines, compared with the Australian cultivars, showing the potential for selection of higher yielding lines. The Brazilian line coded UFRGS037031-3 was the highest yielding line in both high yielding conditions at Grafton and moisture stressed conditions at Wellcamp, and should be the focus of any further evaluation. The Brazilian grain oat lines have very strong resistance to leaf rust compared with Australian cultivars. Further research is needed to determine the potential demand for grain oats as a feed grain in Queensland and to determine the profitability of grain oats to farmers as an alternative winter cereal.

Three rates of nitrogen fertiliser (88, 176 and 352 kg N ha-1 as ammonium nitrate) and 3 of potassium (0, 220 and 440 kg K ha-l as potassium sulfate) were applied to mature Ellendale mandarin trees, in the Central Burnett district, Qld. Optimum yield response occurred at the I76 kg N ha-1 nitrogen rate but potassium treatments did not significantly affect yield. Rind was thinner and fruit colour better at the lowest nitrogen and potassium rate. Whereas nitrogen produced no effect on internal fruit quality, the ratio of total soluble solids:acid was depressed by the highest potassium rate as a result of increased acid content. For Ellendale mandarins under Queensland conditions the lowest potassium treatment produced smaller fruit with thinner rind and earlier colour development. The results indicate that the optimum nitrogen fertiliser application rate is 160-180 kg N ha-1 and that potassium fertilisers can impair fruit quality.

The six species of mountain frogs (Philoria: Limnodynastidae: Anura) are endemic to south-eastern Australia. Five species occur in headwater systems in mountainous north-eastern New South Wales (NSW) and south-eastern Queensland (Qld), centred on the Gondwana Rainforests of Australia World Heritage Area. A previous molecular genetic analysis identified divergent genetic lineages in the central and western McPherson Ranges region of Qld and NSW, but sampling was inadequate to test the species status of these lineages. With more comprehensive geographic sampling and examination of the nuclear genome using SNP analysis, we show that an undescribed species, P. knowlesi sp. nov., occurs in the central and western McPherson Ranges (Levers Plateau and Mount Barney complex). The new species is not phylogenetically closely related to P. loveridgei in the nuclear data but is related to one of two divergent lineages within P. loveridgei in the mtDNA data. We postulate that the discordance between the nuclear and mtDNA outcomes is due to ancient introgression of the mtDNA genome from P. loveridgei into the new species. Male advertisement calls and multivariate morphological analyses do not reliably distinguish P. knowlesi sp. nov. from any of the Philoria species in northeast NSW and southeast Qld. The genetic comparisons also enable us to define further the distributions of P. loveridgei and P. kundagungan. Samples from the Lamington Plateau, Springbrook Plateau, Wollumbin (Mt Warning National Park), and the Nightcap Range, are all P. loveridgei, and its distribution is now defined as the eastern McPherson Ranges and Tweed caldera. Philoria kundagungan is distributed from the Mistake Mountains in south-eastern Qld to the Tooloom Scrub on the Koreelah Range, southwest of Woodenbong, in NSW, with two subpopulations identified by SNP analysis. We therefore assessed the IUCN threat category of P. loveridgei and P. kundagungan and undertook new assessments for each of its two subpopulations and for the new taxon P. knowlesi sp. nov., using IUCN Red List criteria. Philoria loveridgei, P. kundagungan (entire range and northern subpopulation separately) and P. knowlesi sp. nov. each meet criteria for “Endangered” (EN B2(a)(b)[i, iii]). The southern subpopulation of P. kundagungan, in the Koreelah Range, meets criteria for “Critically Endangered” (CE B2(a)(b)[i, iii]). These taxa are all highly threatened due to the small number of known locations, the restricted nature of their breeding habitat, and direct and indirect threats from climate change, and the potential impact of the amphibian disease chytridiomycosis. Feral pigs are an emerging threat, with significant impacts now observed in Philoria breeding habitat in the Mistake Mountains.

Context The Australian cotton industry has committed to (1) understanding the biodiversity value of remnant native vegetation on cotton farms, (2) funding independent, evidence-based assessments of the industry’s sustainability and environmental performance, and (3) investing in research that reports against recognised sustainability indicators. Aims The present study reports the results of an industry-wide survey to benchmark bird diversity in native vegetation on cotton farms spanning a 1260-km north–south subcontinental gradient from Central Queensland (Qld) to Southern New South Wales (NSW). Methods Between September and November 2014, birds were sampled twice on separate days in 2-ha quadrats (20 min per census) in eight remnant vegetation types as well as in native revegetation at 197 sites on 60 cotton farms spread across the principal cotton-growing zones (Central Qld, Border Rivers, Macquarie and Southern NSW) in inland eastern Australia. Key results We recorded 185 bird species in remnant and planted native vegetation on cotton farms. Species richness of bird communities declined from north to south. Bird community composition was similar in the three southern zones, differing somewhat in the north. The most frequent species were large (>60 g), readily detected landbirds common in agricultural districts, but 26 of the 53 extant species of conservation concern in the study region were also recorded, including 16 species of declining woodland birds. Bird composition, abundance, richness and diversity differed among the nine native vegetation types, with maximal and minimal bird abundance and diversity metrics recorded in river red gum-dominated riparian vegetation and grassland respectively. Conclusions Each remnant vegetation community had a generally distinct bird assemblage, indicating that all vegetation types contribute to regional biodiversity in cotton-growing zones in inland eastern Australia. Appropriate on-farm management of all remnant and planted native vegetation will assist regional biodiversity conservation. Implications For the Australian cotton industry to meet its stated environmental responsibilities, growers should be encouraged to prioritise the conservation management of remnant, riparian and planted native vegetation on cotton farms and the monitoring of bird species as an indicator of regional biodiversity response.

Brucella suis is a zoonotic disease of feral pigs that also affects pig hunting dogs, pig hunters, veterinarians and veterinary staff. In recent years the incidence of B. suis in the eastern Australian states of New South Wales (NSW) and Queensland (QLD) has increased. A cross-sectional study was conducted to document the seroprevalence, geographical extent and risk factors for B. suis in dogs at-risk of contracting the disease. Eligible dogs were those that were known to hunt or consume feral pig meat. Dogs were enrolled through private veterinary clinics and/or directly by District Veterinarians in six regions of NSW and QLD. Blood was collected by venepuncture and tested for B. suis antibodies using the Rose Bengal Test (RBT) followed by a Complement Fixation Test (CFT) if they returned a positive RBT. Owners were invited to complete a questionnaire on the dogs' signalment, husbandry including hunting practices and locations, and any clinical signs referable to brucellosis. Of the 317 dogs included in the prevalence survey, 21 were seropositive returning a survey-adjusted true seroprevalence of 9.3 (95% CI 0.45 to 18) B. suis positive dogs per 100 dogs at-risk. True seroprevalence ranged from 0 to 24 B. suis positive dogs per 100 across eastern Australia, with the highest prevalence in central west NSW and southern QLD. Adjusted for other factors, dogs that shared a household with other seropositive dogs and those that traveled away from their home regions to hunt were more likely to be seropositive. Clinical signs at presentation were not predictive of serostatus, with seropositive and seronegative dogs equally likely to present with signs consistent with brucellosis. The results obtained from this study show that B. suis exposure is relatively common in dogs that have contact with feral pigs, with one in 10 testing seropositive. Further studies are needed to understand the progression and risk of transmission from seropositive dogs.

Unconventional energy sources have become increasingly important to the global energy mix. These include coal seam gas, shale gas and shale oil. The unconventional gas industry was pioneered in the United States and embraced following the first oil shock in 1973 (Rogers). As has been the case with many global resources (Hiscock), many of the same companies that worked in the USA carried their experience in this industry to early Australian explorations. Recently the USA has secured significant energy security with the development of unconventional energy deposits such as the Marcellus shale gas and the Bakken shale oil (Dobb; McGraw). But this has not come without environmental impact, including contamination to underground water supply (Osborn, Vengosh, Warner, Jackson) and potential greenhouse gas contributions (Howarth, Santoro, Ingraffea; McKenna). The environmental impact of unconventional gas extraction has raised serious public concern about the introduction and growth of the industry in Australia. In coal rich Australia coal seam gas is currently the major source of unconventional gas. Large gas deposits have been found in prime agricultural land along eastern Australia, such as the Liverpool Plains in New South Wales and the Darling Downs in Queensland. Competing land-uses and a series of environmental incidents from the coal seam gas industry have warranted major protest from a coalition of environmentalists and farmers (Berry; McLeish). Conflict between energy companies wanting development and environmentalists warning precaution is an easy script to cast for frontline media coverage. But historical perspectives are often missing in these contemporary debates. While coal mining and natural gas have often received “boosting” historical coverage (Diamond; Wilkinson), and although historical themes of “development” and “rushes” remain predominant when observing the span of the industry (AGA; Blainey), the history of unconventional gas, particularly the history of its environmental impact, has been little studied. Few people are aware, for example, that the first shale gas exploratory well was completed in late 2010 in the Cooper Basin in Central Australia (Molan) and is considered as a “new” frontier in Australian unconventional gas. Moreover many people are unaware that the first coal seam gas wells were completed in 1976 in Queensland. The first four wells offer an important moment for reflection in light of the industry’s recent move into Central Australia. By locating and analysing the first four coal seam gas wells, this essay identifies the roots of the unconventional gas industry in Australia and explores the early environmental impact of these wells. By analysing exploration reports that have been placed online by the Queensland Department of Natural Resources and Mines through the lens of environmental history, the dominant developmental narrative of this industry can also be scrutinised. These narratives often place more significance on economic and national benefits while displacing the environmental and social impacts of the industry (Connor, Higginbotham, Freeman, Albrecht; Duus; McEachern; Trigger). This essay therefore seeks to bring an environmental insight into early unconventional gas mining in Australia. As the author, I am concerned that nearly four decades on and it seems that no one has heeded the warning gleaned from these early wells and early exploration reports, as gas exploration in Australia continues under little scrutiny. Arrival The first four unconventional gas wells in Australia appear at the beginning of the industry world-wide (Schraufnagel, McBane, and Kuuskraa; McClanahan). The wells were explored by Houston Oils and Minerals—a company that entered the Australian mining scene by sharing a mining prospect with International Australian Energy Company (Wiltshire). The International Australian Energy Company was owned by Black Giant Oil Company in the US, which in turn was owned by International Royalty and Oil Company also based in the US. The Texan oilman Robert Kanton held a sixteen percent share in the latter. Kanton had an idea that the Mimosa Syncline in the south-eastern Bowen Basin was a gas trap waiting to be exploited. To test the theory he needed capital. Kanton presented the idea to Houston Oil and Minerals which had the financial backing to take the risk. Shotover No. 1 was drilled by Houston Oil and Minerals thirty miles south-east of the coal mining town of Blackwater. By late August 1975 it was drilled to 2,717 metres, discovered to have little gas, spudded, and, after a spend of $610,000, abandoned. The data from the Shotover well showed that the porosity of the rocks in the area was not a trap, and the Mimosa Syncline was therefore downgraded as a possible hydrocarbon location. There was, however, a small amount of gas found in the coal seams (Benbow 16). The well had passed through the huge coal seams of both the Bowen and Surat basins—important basins for the future of both the coal and gas industries. Mining Concepts In 1975, while Houston Oil and Minerals was drilling the Shotover well, US Steel and the US Bureau of Mines used hydraulic fracture, a technique already used in the petroleum industry, to drill vertical surface wells to drain gas from a coal seam (Methane Drainage Taskforce 102). They were able to remove gas from the coal seam before it was mined and sold enough to make a profit. With the well data from the Shotover well in Australia compiled, Houston returned to the US to research the possibility of harvesting methane in Australia. As the company saw it, methane drainage was “a novel exploitation concept” and the methane in the Bowen Basin was an “enormous hydrocarbon resource” (Wiltshire 7). The Shotover well passed through a section of the German Creek Coal measures and this became their next target. In September 1976 the Shotover well was re-opened and plugged at 1499 meters to become Australia’s first exploratory unconventional gas well. By the end of the month the rig was released and gas production tested. At one point an employee on the drilling operation observed a gas flame “the size of a 44 gal drum” (HOMA, “Shotover # 1” 9). But apart from the brief show, no gas flowed. And yet, Houston Oil and Minerals was not deterred, as they had already taken out other leases for further prospecting (Wiltshire 4). Only a week after the Shotover well had failed, Houston moved the methane search south-east to an area five miles north of the Moura township. Houston Oil and Minerals had researched the coal exploration seismic surveys of the area that were conducted in 1969, 1972, and 1973 to choose the location. Over the next two months in late 1976, two new wells—Kinma No.1 and Carra No.1—were drilled within a mile from each other and completed as gas wells. Houston Oil and Minerals also purchased the old oil exploration well Moura No. 1 from the Queensland Government and completed it as a suspended gas well. The company must have mined the Department of Mines archive to find Moura No.1, as the previous exploration report from 1969 noted methane given off from the coal seams (Sell). By December 1976 Houston Oil and Minerals had three gas wells in the vicinity of each other and by early 1977 testing had occurred. The results were disappointing with minimal gas flow at Kinma and Carra, but Moura showed a little more promise. Here, the drillers were able to convert their Fairbanks-Morse engine driving the pump from an engine run on LPG to one run on methane produced from the well (Porter, “Moura # 1”). Drink This? Although there was not much gas to find in the test production phase, there was a lot of water. The exploration reports produced by the company are incomplete (indeed no report was available for the Shotover well), but the information available shows that a large amount of water was extracted before gas started to flow (Porter, “Carra # 1”; Porter, “Moura # 1”; Porter, “Kinma # 1”). As Porter’s reports outline, prior to gas flowing, the water produced at Carra, Kinma and Moura totalled 37,600 litres, 11,900 and 2,900 respectively. It should be noted that the method used to test the amount of water was not continuous and these amounts were not the full amount of water produced; also, upon gas coming to the surface some of the wells continued to produce water. In short, before any gas flowed at the first unconventional gas wells in Australia at least 50,000 litres of water were taken from underground. Results show that the water was not ready to drink (Mathers, “Moura # 1”; Mathers, “Appendix 1”; HOMA, “Miscellaneous Pages” 21-24). The water had total dissolved solids (minerals) well over the average set by the authorities (WHO; Apps Laboratories; NHMRC; QDAFF). The well at Kinma recorded the highest levels, almost two and a half times the unacceptable standard. On average the water from the Moura well was of reasonable standard, possibly because some water was extracted from the well when it was originally sunk in 1969; but the water from Kinma and Carra was very poor quality, not good enough for crops, stock or to be let run into creeks. The biggest issue was the sodium concentration; all wells had very high salt levels. Kinma and Carra were four and two times the maximum standard respectively. In short, there was a substantial amount of poor quality water produced from drilling and testing the three wells. Fracking Australia Hydraulic fracturing is an artificial process that can encourage more gas to flow to the surface (McGraw; Fischetti; Senate). Prior to the testing phase at the Moura field, well data was sent to the Chemical Research and Development Department at Halliburton in Oklahoma, to examine the ability to fracture the coal and shale in the Australian wells. Halliburton was the founding father of hydraulic fracture. In Oklahoma on 17 March 1949, operating under an exclusive license from Standard Oil, this company conducted the first ever hydraulic fracture of an oil well (Montgomery and Smith). To come up with a program of hydraulic fracturing for the Australian field, Halliburton went back to the laboratory. They bonded together small slabs of coal and shale similar to Australian samples, drilled one-inch holes into the sample, then pressurised the holes and completed a “hydro-frac” in miniature. “These samples were difficult to prepare,” they wrote in their report to Houston Oil and Minerals (HOMA, “Miscellaneous Pages” 10). Their program for fracturing was informed by a field of science that had been evolving since the first hydraulic fracture but had rapidly progressed since the first oil shock. Halliburton’s laboratory test had confirmed that the model of Perkins and Kern developed for widths of hydraulic fracture—in an article that defined the field—should also apply to Australian coals (Perkins and Kern). By late January 1977 Halliburton had issued Houston Oil and Minerals with a program of hydraulic fracture to use on the central Queensland wells. On the final page of their report they warned: “There are many unknowns in a vertical fracture design procedure” (HOMA, “Miscellaneous Pages” 17). In July 1977, Moura No. 1 became the first coal seam gas well hydraulically fractured in Australia. The exploration report states: “During July 1977 the well was killed with 1% KCL solution and the tubing and packer were pulled from the well … and pumping commenced” (Porter 2-3). The use of the word “kill” is interesting—potassium chloride (KCl) is the third and final drug administered in the lethal injection of humans on death row in the USA. Potassium chloride was used to minimise the effect on parts of the coal seam that were water-sensitive and was the recommended solution prior to adding other chemicals (Montgomery and Smith 28); but a word such as “kill” also implies that the well and the larger environment were alive before fracking commenced (Giblett; Trigger). Pumping recommenced after the fracturing fluid was unloaded. Initially gas supply was very good. It increased from an average estimate of 7,000 cubic feet per day to 30,000, but this only lasted two days before coal and sand started flowing back up to the surface. In effect, the cleats were propped open but the coal did not close and hold onto them which meant coal particles and sand flowed back up the pipe with diminishing amounts of gas (Walters 12). Although there were some interesting results, the program was considered a failure. In April 1978, Houston Oil and Minerals finally abandoned the methane concept. Following the failure, they reflected on the possibilities for a coal seam gas industry given the gas prices in Queensland: “Methane drainage wells appear to offer no economic potential” (Wooldridge 2). At the wells they let the tubing drop into the hole, put a fifteen foot cement plug at the top of the hole, covered it with a steel plate and by their own description restored the area to its “original state” (Wiltshire 8). Houston Oil and Minerals now turned to “conventional targets” which included coal exploration (Wiltshire 7). A Thousand Memories The first four wells show some of the critical environmental issues that were present from the outset of the industry in Australia. The process of hydraulic fracture was not just a failure, but conducted on a science that had never been tested in Australia, was ponderous at best, and by Halliburton’s own admission had “many unknowns”. There was also the role of large multinationals providing “experience” (Briody; Hiscock) and conducting these tests while having limited knowledge of the Australian landscape. Before any gas came to the surface, a large amount of water was produced that was loaded with a mixture of salt and other heavy minerals. The source of water for both the mud drilling of Carra and Kinma, as well as the hydraulic fracture job on Moura, was extracted from Kianga Creek three miles from the site (HOMA, “Carra # 1” 5; HOMA, “Kinma # 1” 5; Porter, “Moura # 1”). No location was listed for the disposal of the water from the wells, including the hydraulic fracture liquid. Considering the poor quality of water, if the water was disposed on site or let drain into a creek, this would have had significant environmental impact. Nobody has yet answered the question of where all this water went. The environmental issues of water extraction, saline water and hydraulic fracture were present at the first four wells. At the first four wells environmental concern was not a priority. The complexity of inter-company relations, as witnessed at the Shotover well, shows there was little time. The re-use of old wells, such as the Moura well, also shows that economic priorities were more important. Even if environmental information was considered important at the time, no one would have had access to it because, as handwritten notes on some of the reports show, many of the reports were “confidential” (Sell). Even though coal mines commenced filing Environmental Impact Statements in the early 1970s, there is no such documentation for gas exploration conducted by Houston Oil and Minerals. A lack of broader awareness for the surrounding environment, from floral and faunal health to the impact on habitat quality, can be gleaned when reading across all the exploration reports. Nearly four decades on and we now have thousands of wells throughout the world. Yet, the challenges of unconventional gas still persist. The implications of the environmental history of the first four wells in Australia for contemporary unconventional gas exploration and development in this country and beyond are significant. Many environmental issues were present from the beginning of the coal seam gas industry in Australia. Owning up to this history would place policy makers and regulators in a position to strengthen current regulation. The industry continues to face the same challenges today as it did at the start of development—including water extraction, hydraulic fracturing and problems associated with drilling through underground aquifers. Looking more broadly at the unconventional gas industry, shale gas has appeared as the next target for energy resources in Australia. Reflecting on the first exploratory shale gas wells drilled in Central Australia, the chief executive of the company responsible for the shale gas wells noted their deliberate decision to locate their activities in semi-desert country away from “an area of prime agricultural land” and conflict with environmentalists (quoted in Molan). Moreover, the journalist Paul Cleary recently complained about the coal seam gas industry polluting Australia’s food-bowl but concluded that the “next frontier” should be in “remote” Central Australia with shale gas (Cleary 195). It appears that preference is to move the industry to the arid centre of Australia, to the ecologically and culturally unique Lake Eyre Basin region (Robin and Smith). Claims to move the industry away from areas that might have close public scrutiny disregard many groups in the Lake Eyre Basin, such as Aboriginal rights to land, and appear similar to other industrial projects that disregard local inhabitants, such as mega-dams and nuclear testing (Nixon).

IntroductionIn July 1997, the Mackay campus of Central Queensland University hosted a conference with the theme Regional Australia: Visions of Mackay. It was the first academic conference to be held at the young campus, and its aim was to provide an opportunity for academics, business people, government officials, and other interested parties to discuss their visions for the development of Mackay, a regional community of 75,000 people situated on the Central Queensland coast (Danaher). I delivered a presentation at that conference and authored a chapter in the book that emerged from its proceedings. The chapter entitled “Mackay Online” explored the potential impact that the Internet could have on the Mackay region, particularly in the areas of regional business, education, health, and entertainment (Pace). Two decades later, how does the reality compare with that vision?Broadband BluesAt the time of the Visions of Mackay conference, public commercial use of the Internet was in its infancy. Many Internet services and technologies that users take for granted today were uncommon or non-existent then. Examples include online video, video-conferencing, Voice over Internet Protocol (VoIP), blogs, social media, peer-to-peer file sharing, payment gateways, content management systems, wireless data communications, smartphones, mobile applications, and tablet computers. In 1997, most users connected to the Internet using slow dial-up modems with speeds ranging from 28.8 Kbps to 33.6 Kbps. 56 Kbps modems had just become available. Lamenting these slow data transmission speeds, I looked forward to a time when widespread availability of high-bandwidth networks would allow the Internet’s services to “expand to include electronic commerce, home entertainment and desktop video-conferencing” (Pace 103). Although that future eventually arrived, I incorrectly anticipated how it would arrive.In 1997, Optus and Telstra were engaged in the rollout of hybrid fibre coaxial (HFC) networks in Sydney, Melbourne, and Brisbane for the Optus Vision and Foxtel pay TV services (Meredith). These HFC networks had a large amount of unused bandwidth, which both Telstra and Optus planned to use to provide broadband Internet services. Telstra's Big Pond Cable broadband service was already available to approximately one million households in Sydney and Melbourne (Taylor), and Optus was considering extending its cable network into regional Australia through partnerships with smaller regional telecommunications companies (Lewis). These promising developments seemed to point the way forward to a future high-bandwidth network, but that was not the case. A short time after the Visions of Mackay conference, Telstra and Optus ceased the rollout of their HFC networks in response to the invention of Asynchronous Digital Subscriber Line (ADSL), a technology that increases the bandwidth of copper wire and enables Internet connections of up to 6 Mbps over the existing phone network. ADSL was significantly faster than a dial-up service, it was broadly available to homes and businesses across the country, and it did not require enormous investment in infrastructure. However, ADSL could not offer speeds anywhere near the 27 Mbps of the HFC networks. When it came to broadband provision, Australia seemed destined to continue playing catch-up with the rest of the world. According to data from the Organisation for Economic Cooperation and Development (OECD), in 2009 Australia ranked 18th in the world for broadband penetration, with 24.1 percent of Australians having a fixed-line broadband subscription. Statistics like these eventually prompted the federal government to commit to the deployment of a National Broadband Network (NBN). In 2009, the Kevin Rudd Government announced that the NBN would combine fibre-to-the-premises (FTTP), fixed wireless, and satellite technologies to deliver Internet speeds of up to 100 Mbps to 90 percent of Australian homes, schools, and workplaces (Rudd).The rollout of the NBN in Mackay commenced in 2013 and continued, suburb by suburb, until its completion in 2017 (Frost, “Mackay”; Garvey). The rollout was anything but smooth. After a change of government in 2013, the NBN was redesigned to reduce costs. A mixed copper/optical technology known as fibre-to-the-node (FTTN) replaced FTTP as the preferred approach for providing most NBN connections. The resulting connection speeds were significantly slower than the 100 Mbps that was originally proposed. Many Mackay premises could only achieve a maximum speed of 40 Mbps, which led to some overcharging by Internet service providers, and subsequent compensation for failing to deliver services they had promised (“Optus”). Some Mackay residents even complained that their new NBN connections were slower than their former ADSL connections. NBN Co representatives claimed that the problems were due to “service providers not buying enough space in the network to provide the service they had promised to customers” (“Telcos”). Unsurprisingly, the number of complaints about the NBN that were lodged with the Telecommunications Industry Ombudsman skyrocketed during the last six months of 2017. Queensland complaints increased by approximately 40 percent when compared with the same period during the previous year (“Qld”).Despite the challenges presented by infrastructure limitations, the rollout of the NBN was a boost for the Mackay region. For some rural residents, it meant having reliable Internet access for the first time. Frost, for example, reports on the experiences of a Mackay couple who could not get an ADSL service at their rural home because it was too far away from the nearest telephone exchange. Unreliable 3G mobile broadband was the only option for operating their air-conditioning business. All of that changed with the arrival of the NBN. “It’s so fast we can run a number of things at the same time”, the couple reported (“NBN”).Networking the NationOne factor that contributed to the uptake of Internet services in the Mackay region after the Visions of Mackay conference was the Australian Government’s Networking the Nation (NTN) program. When the national telecommunications carrier Telstra was partially privatised in 1997, and further sold in 1999, proceeds from the sale were used to fund an ambitious communications infrastructure program named Networking the Nation (Department of Communications, Information Technology and the Arts). The program funded projects that improved the availability, accessibility, affordability, and use of communications facilities and services throughout regional Australia. Eligibility for funding was limited to not-for-profit organisations, including local councils, regional development organisations, community groups, local government associations, and state and territory governments.In 1998, the Mackay region received $930,000 in Networking the Nation funding for Mackay Regionlink, a project that aimed to provide equitable community access to online services, skills development for local residents, an affordable online presence for local business and community organisations, and increased external awareness of the Mackay region (Jewell et al.). One element of the project was a training program that provided basic Internet skills to 2,168 people across the region over a period of two years. A second element of the project involved the establishment of 20 public Internet access centres in locations throughout the region, such as libraries, community centres, and tourist information centres. The centres provided free Internet access to users and encouraged local participation and skill development. More than 9,200 users were recorded in these centres during the first year of the project, and the facilities remained active until 2006. A third element of the project was a regional web portal that provided a free easily-updated online presence for community organisations. The project aimed to have every business and community group in the Mackay region represented on the website, with hosting fees for the business web pages funding its ongoing operation and development. More than 6,000 organisations were listed on the site, and the project remained financially viable until 2005.The availability, affordability and use of communications facilities and services in Mackay increased significantly during the period of the Regionlink project. Changes in technology, services, markets, competition, and many other factors contributed to this increase, so it is difficult to ascertain the extent to which Mackay Regionlink fostered those outcomes. However, the large number of people who participated in the Regionlink training program and made use of the public Internet access centres, suggests that the project had a positive influence on digital literacy in the Mackay region.The Impact on BusinessThe Internet has transformed regional business for both consumers and business owners alike since the Visions of Mackay conference. When Mackay residents made a purchase in 1997, their choice of suppliers was limited to a few local businesses. Today they can shop online in a global market. Security concerns were initially a major obstacle to the growth of electronic commerce. Consumers were slow to adopt the Internet as a place for doing business, fearing that their credit card details would be vulnerable to hackers once they were placed online. After observing the efforts that finance and software companies were making to eliminate those obstacles, I anticipated that it would only be a matter of time before online transactions became commonplace:Consumers seeking a particular product will be able to quickly find the names of suitable suppliers around the world, compare their prices, and place an order with the one that can deliver the product at the cheapest price. (Pace 106)This expectation was soon fulfilled by the arrival of online payment systems such as PayPal in 1998, and online shopping services such as eBay in 1997. eBay is a global online auction and shopping website where individuals and businesses buy and sell goods and services worldwide. The eBay service is free to use for buyers, but sellers are charged modest fees when they make a sale. It exemplifies the notion of “friction-free capitalism” articulated by Gates (157).In 1997, regional Australian business owners were largely sceptical about the potential benefits the Internet could bring to their businesses. Only 11 percent of Australian businesses had some form of web presence, and less than 35 percent of those early adopters felt that their website was significant to their business (Department of Industry, Science and Tourism). Anticipating the significant opportunities that the Internet offered Mackay businesses to compete in new markets, I recommended that they work “towards the goal of providing products and services that meet the needs of international consumers as well as local ones” (107). In the two decades that have passed since that time, many Mackay businesses have been doing just that. One prime example is Big on Shoes (bigonshoes.com.au), a retailer of ladies’ shoes from sizes five to fifteen (Plane). Big on Shoes has physical shopfronts in Mackay and Moranbah, an online store that has been operating since 2009, and more than 12,000 followers on Facebook. This speciality store caters for women who have traditionally been unable to find shoes in their size. As the store’s customer base has grown within Australia and internationally, an unexpected transgender market has also emerged. In 2018 Big on Shoes was one of 30 regional businesses featured in the first Facebook and Instagram Annual Gift Guide, and it continues to build on its strengths (Cureton).The Impact on HealthThe growth of the Internet has improved the availability of specialist health services for people in the Mackay region. Traditionally, access to surgical services in Mackay has been much more limited than in metropolitan areas because of the shortage of specialists willing to practise in regional areas (Green). In 2003, a senior informant from the Royal Australasian College of Surgeons bluntly described the Central Queensland region from Mackay to Gladstone as “a black hole in terms of surgery” (Birrell et al. 15). In 1997 I anticipated that, although the Internet would never completely replace a visit to a local doctor or hospital, it would provide tools that improve the availability of specialist medical services for people living in regional areas. Using these tools, doctors would be able to “analyse medical images captured from patients living in remote locations” and “diagnose patients at a distance” (Pace 108).These expectations have been realised in the form of Queensland Health’s Telehealth initiative, which permits medical specialists in Brisbane and Townsville to conduct consultations with patients at the Mackay Base Hospital using video-conference technology. Telehealth reduces the need for patients to travel for specialist advice, and it provides health professionals with access to peer support. Averill (7), for example, reports on the experience of a breast cancer patient at the Mackay Base Hospital who was able to participate in a drug trial with a Townsville oncologist through the Telehealth network. Mackay health professionals organised the patient’s scans, administered blood tests, and checked her lymph nodes, blood pressure and weight. Townsville health professionals then used this information to advise the Mackay team about her ongoing treatment. The patient expressed appreciation that the service allowed her to avoid the lengthy round-trip to Townsville. Prior to being offered the Telehealth option, she had refused to participate in the trial because “the trip was just too much of a stumbling block” (Averill 7).The Impact on Media and EntertainmentThe field of media and entertainment is another aspect of regional life that has been reshaped by the Internet since the Visions of Mackay conference. Most of these changes have been equally apparent in both regional and metropolitan areas. Over the past decade, the way individuals consume media has been transformed by new online services offering user-generated video, video-on-demand, and catch-up TV. These developments were among the changes I anticipated in 1997:The convergence of television and the Internet will stimulate the creation of new services such as video-on-demand. Today television is a synchronous media—programs are usually viewed while they are being broadcast. When high-quality video can be transmitted over the information superhighway, users will be able to watch what they want, when and where they like. […] Newly released movies will continue to be rented, but probably not from stores. Instead, consumers will shop on the information superhighway for movies that can be delivered on demand.In the mid-2000s, free online video-sharing services such as YouTube and Vimeo began to emerge. These websites allow users to freely upload, view, share, comment on, and curate online videos. Subscription-based streaming services such as Netflix and Amazon Prime have also become increasingly popular since that time. These services offer online streaming of a library of films and television programs for a fee of less than 20 dollars per month. Computers, smart TVs, Blu-ray players, game consoles, mobile phones, tablets, and other devices provide a multitude of ways of accessing streaming services. Some of these devices cost less than 100 dollars, while higher-end electronic devices include the capability as a bundled feature. Netflix became available in Mackay at the time of its Australian launch in 2015. The growth of streaming services greatly reduced the demand for video rental shops in the region, and all closed down as a result. The last remaining video rental store in Mackay closed its doors in 2018 after trading for 26 years (“Last”).Some of the most dramatic transformations that have occurred the field of media and entertainment were not anticipated in 1997. The rise of mobile technology, including wireless data communications, smartphones, mobile applications, and tablet computers, was largely unforeseen at that time. Some Internet luminaries such as Vinton Cerf expected that mobile access to the Internet via laptop computers would become commonplace (Lange), but this view did not encompass the evolution of smartphones, and it was not widely held. Similarly, the rise of social media services and the impact they have had on the way people share content and communicate was generally unexpected. In some respects, these phenomena resemble the Black Swan events described by Nassim Nicholas Taleb (xvii)—surprising events with a major effect that are often inappropriately rationalised after the fact. They remind us of how difficult it is to predict the future media landscape by extrapolating from things we know, while failing to take into consideration what we do not know.The Challenge for MackayIn 1997, when exploring the potential impact that the Internet could have on the Mackay region, I identified a special challenge that the community faced if it wanted to be competitive in this new environment:The region has traditionally prospered from industries that control physical resources such as coal, sugar and tourism, but over the last two decades there has been a global ‘shift away from physical assets and towards information as the principal driver of wealth creation’ (Petre and Harrington 1996). The risk for Mackay is that its residents may be inclined to believe that wealth can only be created by means of industries that control physical assets. The community must realise that its value-added information is at least as precious as its abundant natural resources. (110)The Mackay region has not responded well to this challenge, as evidenced by measures such as the Knowledge City Index (KCI), a collection of six indicators that assess how well a city is positioned to grow and advance in today’s technology-driven, knowledge-based economy. A 2017 study used the KCI to conduct a comparative analysis of 25 Australian cities (Pratchett, Hu, Walsh, and Tuli). Mackay rated reasonably well in the areas of Income and Digital Access. But the city’s ratings were “very limited across all the other measures of the KCI”: Knowledge Capacity, Knowledge Mobility, Knowledge Industries and Smart Work (44).The need to be competitive in a technology-driven, knowledge-based economy is likely to become even more pressing in the years ahead. The 2017 World Energy Outlook Report estimated that China’s coal use is likely to have peaked in 2013 amid a rapid shift toward renewable energy, which means that demand for Mackay’s coal will continue to decline (International Energy Agency). The sugar industry is in crisis, finding itself unable to diversify its revenue base or increase production enough to offset falling global sugar prices (Rynne). The region’s biggest tourism drawcard, the Great Barrier Reef, continues to be degraded by mass coral bleaching events and ongoing threats posed by climate change and poor water quality (Great Barrier Reef Marine Park Authority). All of these developments have disturbing implications for Mackay’s regional economy and its reliance on coal, sugar, and tourism. Diversifying the local economy through the introduction of new knowledge industries would be one way of preparing the Mackay region for the impact of new technologies and the economic challenges that lie ahead.ReferencesAverill, Zizi. “Webcam Consultations.” Daily Mercury 22 Nov. 2018: 7.Birrell, Bob, Lesleyanne Hawthorne, and Virginia Rapson.

Introduction: Bubbles and Sport The ephemeral materiality of bubbles – beautiful, spectacular, and distracting but ultimately fragile – when applied to protect or conserve in the interests of sport-media profit, creates conditions that exacerbate existing inequalities in sport and society. Bubbles are usually something to watch, admire, and chase after in their brief yet shiny lives. There is supposed to be, technically, nothing inside them other than one or more gasses, and yet we constantly refer to people and objects being inside bubbles. The metaphor of the bubble has been used to describe the life of celebrities, politicians in purpose-built capital cities like Canberra, and even leftist, environmentally activist urban dwellers. The metaphorical and material qualities of bubbles are aligned—they cannot be easily captured and are liable to change at any time. In this article we address the metaphorical sporting bubble, which is often evoked in describing life in professional sport. This is a vernacular term used to capture and condemn the conditions of life of elite sportspeople (usually men), most commonly after there has been a sport-related scandal, especially of a sexual nature (Rowe). It is frequently paired with connotatively loaded adjectives like pampered and indulged. The sporting bubble is rarely interrogated in academic literature, the concept largely being left to the media and moral entrepreneurs. It is represented as involving a highly privileged but also pressurised life for those who live inside it. A sporting bubble is a world constructed for its most prized inhabitants that enables them to be protected from insurgents and to set the terms of their encounters with others, especially sport fans and disciplinary agents of the state. The Covid-19 pandemic both reinforced and reconfigured the operational concept of the bubble, re-arranging tensions between safety (protecting athletes) and fragility (short careers, risks of injury, etc.) for those within, while safeguarding those without from bubble contagion. Privilege and Precarity Bubble-induced social isolation, critics argue, encourages a loss of perspective among those under its protection, an entitled disconnection from the usual rules and responsibilities of everyday life. For this reason, the denizens of the sporting bubble are seen as being at risk to themselves and, more troublingly, to those allowed temporarily to penetrate it, especially young women who are first exploited by and then ejected from it (Benedict). There are many well-documented cases of professional male athletes “behaving badly” and trying to rely on institutional status and various versions of the sporting bubble for shelter (Flood and Dyson; Reel and Crouch; Wade). In the age of mobile and social media, it is increasingly difficult to keep misbehaviour in-house, resulting in a slew of media stories about, for example, drunkenness and sexual misconduct, such as when then-Sydney Roosters co-captain Mitchell Pearce was suspended and fined in 2016 after being filmed trying to force an unwanted kiss on a woman and then simulating a lewd act with her dog while drunk. There is contestation between those who condemn such behaviour as aberrant and those who regard it as the conventional expression of youthful masculinity as part of the familiar “boys will be boys” dictum. The latter naturalise an inequitable gender order, frequently treating sportsmen as victims of predatory women, and ignoring asymmetries of power between men and women, especially in homosocial environments (Toffoletti). For those in the sporting bubble (predominantly elite sportsmen and highly paid executives, also mostly men, with an array of service staff of both sexes moving in and out of it), life is reflected for those being protected via an array of screens (small screens in homes and indoor places of entertainment, and even smaller screens on theirs and others’ phones, as well as huge screens at sport events). These male sport stars are paid handsomely to use their skill and strength to perform for the sporting codes, their every facial expression and bodily action watched by the media and relayed to audiences. This is often a precarious existence, the usually brief career of an athlete worker being dependent on health, luck, age, successful competition with rivals, networks, and club and coach preferences. There is a large, aspirational reserve army of athletes vying to play at the elite level, despite risks of injury and invasive, life-changing medical interventions. Responsibility for avoiding performance and image enhancing drugs (PIEDs) also weighs heavily on their shoulders (Connor). Professional sportspeople, in their more reflective moments, know that their time in the limelight will soon be up, meaning that getting a ticket to the sporting bubble, even for a short time, can make all the difference to their post-sport lives and those of their families. The most vulnerable of the small minority of participants in sport who make a good, short-term living from it are those for whom, in the absence of quality education and prior social status, it is their sole likely means of upward social mobility (Spaaij). Elite sport performers are surrounded by minders, doctors, fitness instructors, therapists, coaches, advisors and other service personnel, all supporting athletes to stay focussed on and maximise performance quality to satisfy co-present crowds, broadcasters, sponsors, sports bodies and mass media audiences. The shield offered by the sporting bubble supports the teleological win-at-all-costs mentality of professional sport. The stakes are high, with athlete and executive salaries, sponsorships and broadcasting deals entangled in a complex web of investments in keeping the “talent” pivotal to the “attention economy” (Davenport and Beck)—the players that provide the content for sale—in top form. Yet, the bubble cannot be entirely secured and poor behaviour or performance can have devastating effects, including permanent injury or disability, mental illness and loss of reputation (Rowe, “Scandals and Sport”). Given this fragile materiality of the sporting bubble, it is striking that, in response to the sudden shutdown following the economic and health crisis caused by the 2020 global pandemic, the leaders of professional sport decided to create more of them and seek to seal the metaphorical and material space with unprecedented efficiency. The outcome was a multi-sided tale of mobility, confinement, capital, labour, and the gendering of sport and society. The Covid-19 Gilded Cage Sociologists such as Zygmunt Bauman and John Urry have analysed the socio-politics of mobilities, whereby some people in the world, such as tourists, can traverse the globe at their leisure, while others remain fixed in geographical space because they lack the means to be mobile or, in contrast, are involuntarily displaced by war, so-called “ethnic cleansing”, famine, poverty or environmental degradation. The Covid-19 global pandemic re-framed these matters of mobilities (Rowe, “Subjecting Pandemic Sport”), with conventional moving around—between houses, businesses, cities, regions and countries—suddenly subjected to the imperative to be static and, in perniciously unreflective technocratic discourse, “socially distanced” (when what was actually meant was to be “physically distanced”). The late-twentieth century analysis of the “risk society” by Ulrich Beck, in which the mysterious consequences of humans’ predation on their environment are visited upon them with terrifying force, was dramatically realised with the coming of Covid-19. In another iteration of the metaphor, it burst the bubble of twenty-first century global sport. What we today call sport was formed through the process of sportisation (Maguire), whereby hyper-local, folk physical play was reconfigured as multi-spatial industrialised sport in modernity, becoming increasingly reliant on individual athletes and teams travelling across the landscape and well over the horizon. Co-present crowds were, in turn, overshadowed in the sport economy when sport events were taken to much larger, dispersed audiences via the media, especially in broadcast mode (Nicholson, Kerr, and Sherwood). This lucrative mediation of professional sport, though, came with an unforgiving obligation to generate an uninterrupted supply of spectacular live sport content. The pandemic closed down most sports events and those that did take place lacked the crucial participation of the co-present crowd to provide the requisite event atmosphere demanded by those viewers accustomed to a sense of occasion. Instead, they received a strange spectacle of sport performers operating in empty “cathedrals”, often with a “faked” crowd presence. The mediated sport spectacle under the pandemic involved cardboard cut-out and sex doll spectators, Zoom images of fans on large screens, and sampled sounds of the crowd recycled from sport video games. Confected co-presence produced simulacra of the “real” as Baudrillardian visions came to life. The sporting bubble had become even more remote. For elite sportspeople routinely isolated from the “common people”, the live sport encounter offered some sensory experience of the social – the sounds, sights and even smells of the crowd. Now the sporting bubble closed in on an already insulated and insular existence. It exposed the irony of the bubble as a sign of both privileged mobility and incarcerated athlete work, both refuge and prison. Its logic of contagion also turned a structure intended to protect those inside from those outside into, as already observed, a mechanism to manage the threat of insiders to outsiders. In Australia, as in many other countries, the populace was enjoined by governments and health authorities to help prevent the spread of Covid-19 through isolation and immobility. There were various exceptions, principally those classified as essential workers, a heterogeneous cohort ranging from supermarket shelf stackers to pharmacists. People in the cultural, leisure and sports industries, including musicians, actors, and athletes, were not counted among this crucial labour force. Indeed, the performing arts (including dance, theatre and music) were put on ice with quite devastating effects on the livelihoods and wellbeing of those involved. So, with all major sports shut down (the exception being horse racing, which received the benefit both of government subsidies and expanding online gambling revenue), sport organisations began to represent themselves as essential services that could help sustain collective mental and even spiritual wellbeing. This case was made most aggressively by Australian Rugby League Commission Chairman, Peter V’landys, in contending that “an Australia without rugby league is not Australia”. In similar vein, prominent sport and media figure Phil Gould insisted, when describing rugby league fans in Western Sydney’s Penrith, “they’re lost, because the football’s not on … . It holds their families together. People don’t understand that … . Their life begins in the second week of March, and it ends in October”. Despite misgivings about public safety and equality before the pandemic regime, sporting bubbles were allowed to form, re-form and circulate. The indefinite shutdown of the National Rugby League (NRL) on 23 March 2020 was followed after negotiation between multiple entities by its reopening on 28 May 2020. The competition included a team from another nation-state (the Warriors from Aotearoa/New Zealand) in creating an international sporting bubble on the Central Coast of New South Wales, separating them from their families and friends across the Tasman Sea. Appeals to the mental health of fans and the importance of the NRL to myths of “Australianness” notwithstanding, the league had not prudently maintained a financial reserve and so could not afford to shut down for long. Significant gambling revenue for leagues like the NRL and Australian Football League (AFL) also influenced the push to return to sport business as usual. Sport contests were needed in order to exploit the gambling opportunities – especially online and mobile – stimulated by home “confinement”. During the coronavirus lockdowns, Australians’ weekly spending on gambling went up by 142 per cent, and the NRL earned significantly more than usual from gambling revenue—potentially $10 million above forecasts for 2020. Despite the clear financial imperative at play, including heavy reliance on gambling, sporting bubble-making involved special licence. The state of Queensland, which had pursued a hard-line approach by closing its borders for most of those wishing to cross them for biographical landmark events like family funerals and even for medical treatment in border communities, became “the nation's sporting hub”. Queensland became the home of most teams of the men’s AFL (notably the women’s AFLW season having been cancelled) following a large Covid-19 second wave in Melbourne. The women’s National Netball League was based exclusively in Queensland. This state, which for the first time hosted the AFL Grand Final, deployed sport as a tool in both national sports tourism marketing and internal pre-election politics, sponsoring a documentary, The Sporting Bubble 2020, via its Tourism and Events arm. While Queensland became the larger bubble incorporating many other sporting bubbles, both the AFL and the NRL had versions of the “fly in, fly out” labour rhythms conventionally associated with the mining industry in remote and regional areas. In this instance, though, the bubble experience did not involve long stays in miners’ camps or even the one-night hotel stopovers familiar to the popular music and sport industries. Here, the bubble moved, usually by plane, to fulfil the requirements of a live sport “gig”, whereupon it was immediately returned to its more solid bubble hub or to domestic self-isolation. In the space created between disciplined expectation and deplored non-compliance, the sporting bubble inevitably became the scrutinised object and subject of scandal. Sporting Bubble Scandals While people with a very low risk of spreading Covid-19 (coming from areas with no active cases) were denied entry to Queensland for even the most serious of reasons (for example, the death of a child), images of AFL players and their families socialising and enjoying swimming at the Royal Pines Resort sporting bubble crossed our screens. Yet, despite their (players’, officials’ and families’) relative privilege and freedom of movement under the AFL Covid-Safe Plan, some players and others inside the bubble were involved in “scandals”. Most notable was the case of a drunken brawl outside a Gold Coast strip club which led to two Richmond players being “banished”, suspended for 10 matches, and the club fined $100,000. But it was not only players who breached Covid-19 bubble protocols: Collingwood coaches Nathan Buckley and Brenton Sanderson paid the $50,000 fine imposed on the club for playing tennis in Perth outside their bubble, while Richmond was fined $45,000 after Brooke Cotchin, wife of team captain Trent, posted an image to Instagram of a Gold Coast day spa that she had visited outside the “hub” (the institutionally preferred term for bubble). She was subsequently distressed after being trolled. Also of concern was the lack of physical distancing, and the range of people allowed into the sporting bubble, including babysitters, grandparents, and swimming coaches (for children). There were other cases of players being caught leaving the bubble to attend parties and sharing videos of their “antics” on social media. Biosecurity breaches of bubbles by players occurred relatively frequently, with stern words from both the AFL and NRL leaders (and their clubs) and fines accumulating in the thousands of dollars. Some people were also caught sneaking into bubbles, with Lekahni Pearce, the girlfriend of Swans player Elijah Taylor, stating that it was easy in Perth, “no security, I didn’t see a security guard” (in Barron, Stevens, and Zaczek) (a month later, outside the bubble, they had broken up and he pled guilty to unlawfully assaulting her; Ramsey). Flouting the rules, despite stern threats from government, did not lead to any bubble being popped. The sport-media machine powering sporting bubbles continued to run, the attendant emotional or health risks accepted in the name of national cultural therapy, while sponsorship, advertising and gambling revenue continued to accumulate mostly for the benefit of men. Gendering Sporting Bubbles Designed as biosecurity structures to maintain the supply of media-sport content, keep players and other vital cogs of the machine running smoothly, and to exclude Covid-19, sporting bubbles were, in their most advanced form, exclusive luxury camps that illuminated the elevated socio-cultural status of sportsmen. The ongoing inequalities between men’s and women’s sport in Australia and around the world were clearly in evidence, as well as the politics of gender whereby women are obliged to “care” and men are enabled to be “careless” – or at least to manage carefully their “duty of care”. In Australia, the only sport for women that continued during the height of the Covid-19 lockdown was netball, which operated in a bubble that was one of sacrifice rather than privilege. With minimum salaries of only $30,000 – significantly less than the lowest-paid “rookies” in the AFL – and some being mothers of small children and/or with professional jobs juggled alongside their netball careers, these elite sportswomen wanted to continue to play despite the personal inconvenience or cost (Pavlidis). Not one breach of the netballers out of the bubble was reported, indicating that they took their responsibilities with appropriate seriousness and, perhaps, were subjected to less scrutiny than the sportsmen accustomed to attracting front-page headlines. National Netball League (also known after its Queensland-based naming rights sponsor as Suncorp Super Netball) players could be regarded as fortunate to have the opportunity to be in a bubble and to participate in their competition. The NRL Women’s (NRLW) Premiership season was also completed, but only involved four teams subject to fly in, fly out and bubble arrangements, and being played in so-called curtain-raiser games for the NRL. As noted earlier, the AFLW season was truncated, despite all the prior training and sacrifice required of its players. Similarly, because of their resource advantages, the UK men’s and boy’s top six tiers of association football were allowed to continue during lockdown, compared to only two for women and girls. In the United States, inequalities between men’s and women’s sports were clearly demonstrated by the conditions afforded to those elite sportswomen inside the Women’s National Basketball Association (WNBA) sport bubble in the IMG Academy in Florida. Players shared photos of rodent traps in their rooms, insect traps under their mattresses, inedible food and blocked plumbing in their bubble accommodation. These conditions were a far cry from the luxury usually afforded elite sportsmen, including in Florida’s Walt Disney World for the men’s NBA, and is just one of the many instances of how gendered inequality was both reproduced and exacerbated by Covid-19. Bursting the Bubble As we have seen, governments and corporate leaders in sport were able to create material and metaphorical bubbles during the Covid-19 lockdown in order to transmit stadium sport contests into home spaces. The rationale was the importance of sport to national identity, belonging and the routines and rhythms of life. But for whom? Many women, who still carry the major responsibilities of “care”, found that Covid-19 intensified the affective relations and gendered inequities of “home” as a leisure site (Fullagar and Pavlidis). Rates of domestic violence surged, and many women experienced significant anxiety and depression related to the stress of home confinement and home schooling. During the pandemic, women were also more likely to experience the stress and trauma of being first responders, witnessing virus-related sickness and death as the majority of nurses and care workers. They also bore the brunt of much of the economic and employment loss during this time. Also, as noted above, livelihoods in the arts and cultural sector did not receive the benefits of the “bubble”, despite having a comparable claim to sport in contributing significantly to societal wellbeing. This sector’s workforce is substantially female, although men dominate its senior roles. Despite these inequalities, after the late March to May hiatus, many elite male sportsmen – and some sportswomen - operated in a bubble. Moving in and out of them was not easy. Life inside could be mentally stressful (especially in long stays of up to 150 days in sports like cricket), and tabloid and social media troll punishment awaited those who were caught going “over the fence”. But, life in the sporting bubble was generally preferable to the daily realities of those afflicted by the trauma arising from forced home confinement, and for whom watching moving sports images was scant compensation for compulsory immobility. The ethical foundation of the sparkly, ephemeral fantasy of the sporting bubble is questionable when it is placed in the service of a voracious “media sports cultural complex” (Rowe, Global Media Sport) that consumes sport labour power and rolls back progress in gender relations as a default response to a global pandemic. Covid-19 dramatically highlighted social inequalities in many areas of life, including medical care, work, and sport. For the small minority of people involved in sport who are elite professionals, the only thing worse than being in a sporting bubble during the pandemic was not being in one, as being outside precluded their participation. Being inside the bubble was a privilege, albeit a dubious one. But, as in wider society, not all sporting bubbles are created equal. Some are more opulent than others, and the experiences of the supporting and the supported can be very different. The surface of the sporting bubble may be impermanent, but when its interior is opened up to scrutiny, it reveals some very durable structures of inequality. Bubbles are made to burst. They are, by nature, temporary, translucent structures created as spectacles. As a form of luminosity, bubbles “allow a thing or object to exist only as a flash, sparkle or shimmer” (Deleuze, 52). In echoing Deleuze, Angela McRobbie (54) argues that luminosity “softens and disguises the regulative dynamics of neoliberal society”. The sporting bubble was designed to discharge that function for those millions rendered immobile by home confinement legislation in Australia and around the world, who were having to deal with the associated trauma, risk and disadvantage. Hence, the gender and class inequalities exacerbated by Covid-19, and the precarious and pressured lives of elite athletes, were obscured. We contend that, in the final analysis, the sporting bubble mainly serves those inside, floating tantalisingly out of reach of most of those outside who try to grasp its elusive power. Yet, it is a small group beyond who wield that power, having created bubbles as armoured vehicles to salvage any available profit in the midst of a global pandemic.

In a letter responding to the Federal Government’s refusal to offer a formal apology to the ‘Stolen Generation’ of Indigenous Australians, members of the Vietnamese-Australian community expressed an understanding (often lacked by Anglo-Australians) of the need to appreciate their position as migrants in relation to the Indigenous community: "We are here now, living in cities and towns that once were their hunting grounds, their camping places, their sacred sites. We are the beneficiaries of their dispossession, and we acknowledge their loss. We understand about the loss of home, family and cultural values, and we too would like to express our deep sorrow to all indigenous Australians for their suffering and offer our support for genuine reconciliation." (Le and Nguyen 14) This letter remains one of the few instances in which the contemporary positioning of migrant and Indigenous peoples is discussed in relation to one another. It is demonstrative of some of the points of continuity between the ways Aboriginal and migrant collectivities (especially those who are racially ‘marked’) experience Australian society but, more often than not, these connections remain under-theorised. In Australian debates concerning the significance of descent, belonging and culture, there have been two distinct, yet connected currents (Curthoys 21). One of these debates concerns the positioning of Indigenous and settler Australians within a (continuing) history of colonisation and genocide. The other debate centres on immigration, multiculturalism and ethnic/cultural diversity. Ghassan Hage argues that such distinctions are a reflection of a white governmental tendency that conceives ‘white-Aboriginal’ and ‘Anglo-Ethnic’ relations in oppositional terms. The whites "relating to Aboriginal people appear as totally unaffected by multiculturalism, while the ‘Anglos’ relating to the ‘ethnics’ appear as if they have no Aboriginal question about which to worry" (24). It is only since the mid to late 1990s that debates on both Indigenous and immigration policies (re-ignited by independent member of parliament Pauline Hanson in 1996) have been explicitly connected. This article examines the ambiguous and often strained relationship between the positioning of Indigenous and migrant peoples in contemporary Australian society. While the above letter suggests a degree of sympathy and empathy between recent migrant collectivities and Aboriginal people, such a level of recognition and understanding cannot be taken for granted. The following account of Aboriginal-migrant relations indicates that these are structured by both "complex conflicts and points of solidarity" (Perera and Pugliese 5). Given that both diasporic and Indigenous communities can be the targets of white supremacist ideologies and hostilities, some commonalities between these collectivities become apparent. The "attraction of outsiders to fellow outsiders, the stranger (the [I]ndigenous made a stranger in her or his own land) to the stranger from elsewhere" (Docker and Fischer 15), can result in the creation of common interests and affiliations. However, diasporic communities do not share the same history of colonisation (in Australia, at least) with Indigenous Australians, and may be perceived as yet another set of invaders. Just like the colonisers, more recent migrants are beneficiaries of the original dispossession and (continuing) colonisation of Aboriginal and Torres Strait Islander Australians. The Indigenous and the Diasporic: Tensions and Uncertainties The shared knowledge of being located on the margins of white Australian society has enabled Aboriginal and non-white racial minorities to see many similarities in their circumstances and experiences. Both Aboriginal and non-Anglo migrant collectivities have largely been excluded from dominant ideologies of Australian national belonging. Those migrants who have come to Australia as refugees can often appreciate the feelings of cultural domination and loss that many Aboriginal people experience on a daily basis. Both Aboriginal and NESB collectivities have also come under pressure to adopt the assumed monolithic Australian culture. The assimilation policy offered a chance for Aborigines and NESB migrants to ‘fit in’, but this was on the proviso that they conform. Both NESB and Aboriginal communities experience ongoing structural disadvantages in Australian society and its economy. These collectivities can also suffer discrimination and hostility in their social relations with fellow Australians. Despite these similarities, however, there is often a lack of identification between Aboriginal and migrant collectivities. Australian Indigenous and immigrant peoples have very divergent histories and Aboriginal and Torres Strait Islander people often resist being drawn under the rubric of multiculturalism. Instead, many Indigenous Australians have attacked multiculturalism, claiming that the idea of the equal validity of every culture "reduces them to the status of just another ethnic minority" (Bulbeck 273). Many Aboriginal and Torres Strait Islander people wish to reinforce their status as the ‘first’ or Indigenous peoples of this country; an insistence that does not necessarily assist recognition of the ways in which racism and ethnocentrism impact upon ‘Other’ minorities. Another reason for the relative lack of engagement between Indigenous and diasporic communities is that the political agenda of Aboriginal and Torres Strait Islander people is different from that of other minority collectivities. Indigenous activists have expressed understandable and substantiated fears that the focus on multiculturalism not only overlooks the Indigenous status of Aborigines as ‘first peoples’, but can distract attention from the issues of land rights and Native Title (Gunew 455). Lois O’Donoghue recognises both advantages and disadvantages in contemporary multiculturalism: "Perhaps Aboriginal people have benefited from the greater appreciation of cultural diversity which has resulted from the admission of other points of view". However, "we are the original inhabitants of this land, and our sufferings, past and present, make some form of special recognition a moral imperative" (qtd. in Bulbeck 274). Another difficulty lies is that newly arrived migrants are extended various social rights and privileges that have only relatively recently been granted to Indigenous Australians. Many Indigenes have resented the fact that new groups may be better treated than themselves, with some migrants taking on "the racist stereotypes of Anglo-Australian society" (Vasta 51). In Sang Ye’s interviews with various Chinese migrants in The Year the Dragon Came, for instance, one interviewee claimed that: "Nearly all the Aborigines are unemployed or refuse to take jobs that are available; they’re outside the pubs or on the grass getting drunk on beer" (182). These comments show very clearly that the common experiences of racism that many NESB and Aboriginal Australians share do not automatically guarantee understanding or political solidarity between the two groups (Perera and Pugliese 14). The above quotation also illustrates the way in which NESB Australians can reproduce dominant white Australian characterisations of contemporary Aboriginality. Aboriginal people continue to face popular conceptions of themselves as drunken, lazy, intellectually inferior, or as suitable only for servile or menial work (Morris 171-173). As Ruby Langford Ginibi maintains: They’ve got us stereotyped as nothing but lazy layabout boongs, you know, and they see a Koori fella staggering down the street charged up and they say, ‘Oh, they’re all like that,’ but they never stop, or pause to think, ‘Hey, what’s made this person like this?’ You can’t do what has been done to a race of people without it having disastrous results. (qtd. in Little 105 As long as Anglo- and NESB Australians focus on the low socioeconomic position of Aboriginal people without considering the lasting effects of colonialism, Aborigines will continually be cast as the culprits of their own positioning. Widely-circulated conservative ideologies that blame Aboriginal people for their own victimisation overlook the enduring legacies of colonisation. As Arthur Corunna states in Sally Morgan’s My Place: "You see, the trouble is that colonialism isn’t over yet" (212). According to Suvendrini Perera and Joseph Pugliese, "[i]t is vital that the structural disadvantages and racisms faced by indigenous peoples not be relegated to history, but be seen as ongoing in contemporary Australia" (10). Many Aboriginal communities also feel that because migrants have not, in Australia at least, suffered the same extent of cultural domination, they are less disadvantaged. John Docker argues that each individual in 1788 and since who has come to Australia, however variegated their experiences and "however much there has been racism and ethnocentrism and differential access to power ha[s] benefited from the original invasion and dispossession of the Aboriginal peoples, and still benefit[s]" (54). For Aboriginal people migrant groups could be seen as another set of invaders, "not brothers and sisters on the margins, not the fellow oppressed and dispossessed" (Docker 54). Aboriginal and Torres Strait Islander people have thus avoided conflating their own political agendas – at the foreground of which are land rights and Native Title – with the very different concerns of various migrant communities (Brewster 16). Many Aboriginal people feel that because those migrating to Australia can retain their language, and often have families or communities to go to, they are less disadvantaged. Langford Ginibi’s comments are illustrative: Even the people who migrate here are on a higher social level than we are, and we’re the first people of this land! My people were forced to give away using our language and culture, and adopt the ways of the white man, but the people who migrated here don’t give away their language or culture to become Australian citizens." (52) In her autobiography Born a Half-Caste, Marnie Kennedy makes similar claims: "Every nationality in Australia is allowed to speak its language. They have their own gatherings. These are the things that make Aborigines very bitter because they were made to give up everything that was sacred to them" (4-5). Given the tensions and contradictions outlined above, long-lasting and productive relations between Aboriginal and NESB peoples can sometimes be difficult to forge, but it is important that NESB people recognise their responsibility in the ongoing dispossession of Indigenous Australians. NESB migrants (and all non-Aboriginal Australians) remain the beneficiaries of colonisation but, unlike their Anglo-Australian counterparts, non-white migrants have been racially marked and had their ability to claim the title ‘Australian’ questioned. Ongoing analysis of the positioning of NESB collectivities in relation to Aboriginal peoples will assist in undermining the central conflict of Black vs. white in reconciliation debates. Further research might also help disrupt the continuing cleavage of ‘the immigrant’ and ‘the Indigene’ in contemporary paradigms of reconciliation, providing a space for discussion on the potential role and contribution of NESB Australians to the reconciliation process.

Getting the Family Together: A Fieldwork Account The final gig of Bob Corbett and the Roo Grass Band’s 2013 tour is a hometown show at New Lambton Community Hall in Newcastle on the coast of New South Wales, Australia. The tour had already covered Newcastle and surrounds at various locations within 50 to 100km of the Newcastle CBD. In addition to lead singer and guitarist Bob Corbett, there are three main members of the Roo Grass Band, Sue Carson on fiddle and mandolin, Dave Carter on banjo, bass and bagpipes and Robbie Long on guitar, mandolin and bass. I enter the building and at the top of the stairs a tall, slim woman with a shock of red hair rushes to greet me with a hug, “It is so good to see you!”This is Veronica, Bob Corbett’s Mum. She’s been busy setting up the merchandise desk, taking tickets, and greeting almost every member of the audience by name. Veronica has functioned as de facto tour manager throughout the band’s Lucky Country Hall Tour. As well as running the merchandise desk and ticketing, she’s occasionally acted as roadie, and has supervised the packing of cars and trailers. These day-to-day jobs on the tour have been done with help from either her sister Roberta or, for most of the tour, a close friend of the band, Jenny. I deposit home-made chocolate brownies and biscuits in the kitchen, setting them up alongside fruit brownies made by Veronica for the audience. Bob’s wife, Kirrily, comes and says hello, followed by their son Marley, who heads straight for the goodies. Their daughter Matilda is running around with her best friend and next-door neighbour, Sophie. Dave, who plays banjo, bass and bagpipes in the band, greets his wife Karen as she arrives with their kids. The band’s fiddle player, Sue, is pacing around, looking fractious. I ask if she’s okay. “Yeah, it is just that my family is meant to be here already and they’re running late. They’re going to miss it.”Not long after, Sue’s partner, Michael (who is also Veronica’s brother, Bob’s uncle) arrives with their son Elijah and his son Gabe, in time for the show. This final gig of the tour seemed to have been largely arranged for the families of the band, and there was little advertising for it. In the way of family get-togethers a mix of tension and excitement fill the room. But once the band starts playing things calm down, a group of kids occupy the dance floor, twirling, swaying, skipping and running along with the music. Family, Authenticity, and Commercial Practices in Australian Country MusicI open with this fieldwork account to illuminate how the presence and involvement of family, through parents, spouses, aunts, uncles, children and even close friends are central to the experience of what it is to be a country music artist in Australia. In the case of Bob Corbett and the Roo Grass Band, for example, band members make choices to involve family in the activity of “being” a band—touring, performing, engaging with fans—and these choices have emotional value for them, but are also yoked to broader discourses of family which circulate in the field of Australian country music. This field story reveals that “family” is not something carved off from artists’ public engagement with the field of Australian country music but is central to it. Discourses of and around “family” are implicit in the practices of Australian country music artists and are strategically used by artists to define what country music is and what is valued in the field. Crucially, the discourse of family is used to support claims to authenticity within country music culture. Ideas about and associated practices concerning, “authenticity” permeate the culture of country music. The discourse reaches across all aspects of the field, and all participants in the scene are compelled to at least turn their minds to questions of authenticity, and develop strategies for dealing with them. Value is conferred on artists seen to convey so-called “true” and “genuine” personas. Indeed the country music community demands something referred to as “honesty” from performers. It needs to be noted that country music is a commercial popular music form and culture. Many agents in the scene have an uneasy symbolic relationship with the commercial aspects of country music, but it is a basic premise within the field: the music exists to make money. This is not to say that financial and popular success (in their quantifiable forms: money made, units sold, crowd sizes, radio spins) is the only thing valued in country music. As a form of cultural capital, authenticity is also valued. But within Australian country music a tension exists between the part of field underpinned by commercial logic and the idea of the popular and those underpinned by notions of creativity, independence and musical integrity. Authenticity is deployed to distinguish country music from other styles of music in a number of keys ways. Authenticity can be taken as an essential quality of music, which “honestly” reflects or expresses an identity or experience (e.g., Australian national identity, rural experience, heartbreak) (Watson, Volume 1; Watson, Volume 2; Sanjek); as a proper way of relating music, artist and audience (Smith); as a ideological watchword which tempers commerciality (Sanjek); or as something “fabricated” or constructed in the codification of the genre (Akenson; Peterson; Carriage and Hayward). I am not positing authenticity as a feature unique to Australian country music. A number of authors have highlighted the role authenticity plays in many forms of popular music to navigate, understand or obfuscate the functions of the commercial music industry and shape its output (Frith; Sanjek; Barker and Taylor). The scholarship on country music and popular music in general often explores how authenticity is inscribed in the products of country music, rather than the processes and practices behind those products: the everyday, extra-musical activities of participants in the scene. This article is concerned then with how discourses of authenticity are sutured to business, musical and promotional practices, and how such tropes function alongside discourses and practices concerning “family” in the negotiation of commercial realities in Australian country music. Rather than looking at end products, my research takes a ground-up approach, exploring what people are doing and how they talk about their practices and decisions. Discourses of “family”, and practices around kin, provide one of many possible entry points for this exploration. MethodologyThis article is based on ethnographic research on Australian country music. Between 2012-2014 I spent many months of focused immersion with Bob Corbett and the Roo Grass Band at festivals and on tour. This research was part of broader participant observation I conducted which included attending more than 150 country music events across New South Wales and Queensland. I also conducted hundreds of informal interviews at these events, as well as in-depth, semi-structured interviews with key informants, including band members Bob Corbett, Sue Carson, Robbie Long, and Michael Carpenter (sometimes drummer).Bob Corbett was recognised by the “mainstream” Australian country music scene in 2012 after winning the Star Maker competition. Since the win Bob and the band’s success within the field has increased—higher album sales, larger crowds, more airplay, recognition, sponsorships and nomination for Golden Guitar Awards (the main Australian country music industry awards). They play a mercurial mix of styles including bluegrass, Western swing, pop folk, and rock. At the core is a concern with storytelling and live, acoustic based performance is central. Bob and the band are primarily engaging with the field of Australian country music (through festivals, media, and self-identification), rather than the folk or bluegrass scenes, which, while related, are distinct fields with different logics, rules and relations.The conceptual framework for this article is indebted to Pierre Bourdieu. In using the term “field” to talk about Australian country music, I understand it as a discrete, relatively autonomous social microcosm, which is located within the social space of Australian society and the broader music industry, yet it is ruled by logics which are “specific and irreducible to those that regulate other fields” (Bourdieu in Bourdieu and Wacquant 97). Australian country music consists of systems of relations, which define the occupants of the field—country musicians, country music stars, or country music fans (to name but a few)—and shape the products and practices of the field. Bob Corbett and the Roo Grass Band are participants in the field of Australian country music, and work to differentiate their position, and gain a monopoly over authority and influence within the field—to be recognised as successful, authentic country music artists (Bourdieu and Wacquant 100). This framework allows analytic space for exploring and understanding a tension between authenticity, as a form of cultural capital, and the commercial imperatives of country music as a popular music form.Family Bands and the Family BusinessThe significance and foregrounded presence of “family” within Australian country music is a result of the history of the field in which family bands have been prominent. The practice of touring with your spouse, children or other kin has been connected to a discourse of the “Family Band” in Australian country music. Slim Dusty and his family, as pioneers in the Australian country music industry, and arguably the most commercially and culturally successful artists in the scene’s history, are held up as an example par excellence of the country music canon, and provide the model for how country music should or could be done as a family. Slim, his wife Joy, daughter Anne Kirkpatrick and other extended family worked as a “family band” touring, performing, songwriting, recording, and being country music artists. As the “first family” Australian country music band (Baker; Ellis) they dominate the social and cultural imaginary of Australian country music. They represent a tradition of family involvement in the business of country music as a way of dealing with the practical realities of touring, providing emotional support and enjoyment, and as a part of a relatively conservative set of values drawn from country life­. These features work together to discursively distance the “family band” from the commercial music industry and imbue integrity and naturalness in those artists’ engagement with the music business. Bob Corbett and the Roo Grass Band is a family band: fiddle player Sue is Bob’s aunty; her partner Michael Stove, Bob’s uncle, was an original member of the Roo Grass Band. But more than that, the band understands themselves as a “family”. Sometimes-drummer in the band, Michael Carpenter, talked at length about the “Roo Grass Family” when I interviewed him, including the affective value he places on those relationships:I love it when Bob says… ‘Michael’s been a part of the Roo Grass family for a long time’ … it’s a very country music thing to say … when Bob says it, it actually means something, there’s a certain level of weight to it, because I know the way he treats his bands, I know the way he treats the people who are involved ... it does make them feel like they are a part of something special and so, and that’s beyond just doing a gig … it kind of creates this sense of loyalty that is important to me.The other members of the band also understand and value their involvement with the band in a similar way, and it spills into the chemistry the band has on stage, and the enjoyment they derive from playing together. The idea of the family band opens out beyond the actual band as well: the “Roo Grass Family” includes friends, fans and others with strong ties and involvement with the band.Practical, on the ground support (both on tour and also at home) offered by family to artists in Australian country music is a significant source of capital for those artists. However, participants also talk about this family help as a chance to spend time together, and couch it within discourses of loyalty, love, fun and commitment. Practices and discourses of small, DIY business are also sutured to discourse of family, as a way of reinforcing the fierce independence from big business and record companies. The fieldwork account at the beginning of this article reveals some of the work done by family on tour for Bob and the band, mainly through the presence of Bob’s mum, Veronica, as defacto tour manager. During the gig Bob offered a series of acknowledgments for the tour. After thanking the audiences and tour sponsors, he moved on to family:Bob: I’d like to thank my aunty Roberta, she came along and helped us on a tour leg … Ah, I’m going to forget people, I’m going to leave the special ones to last … I would like to thank Kirrily personally, but as Sue said, all partners and stuff, so I love you Kiz. But the most special one of all: Mrs Veronica Corbett [loud applause and cheers]. She’s the backbone! Of the tour, so thanks mum, thanks for everything.Veronica: Absolute pleasure Bobby.Bob: It’s been, it’s been a pleasure. You love doing it.Veronica: I love it.Bob: Yeah, you do love doing it, it’s been great, you know. I don’t want to get too, too sentimental, but, um just before dad died, he turned to me and said ‘look after mum’, and I don’t, I don’t look after mum, but in a way, just sharing all these experiences, like, we’re looking after each other, so, thank you for doing that.In this account, I am interested in the ways in which Bob, Veronica and Sue talk about the labour provided by family. There are a number of ways that participants talk about the practice of getting family to help do the work of touring and performing country music, which emerge here, and are consistently used by Bob and the band. It is spoken of in terms of “spending time” with each other, and of loving that time. Discourses of enjoyment and sociality permeate Bob, Veronica, and others’ discussions of the practical reality of people giving up their time to help. This is part of the cultural capital of authenticity: being a professional country music band out on the road is about more than hard slog, making money and cold business; it is an enjoyable experience, underpinned with love. To be authentic, it should be about more than the dollars.While the involvement of family in the activities of the band is discussed and understood as a chance to spend time together, an enjoyable experience, there are also discourses of support and help tied to these practices by those in and around the band. It is often acknowledged as a practical reality that family members are involved in the activities of the band (or in maintaining the home front) as a source of free or cheap labour which makes touring and performing possible. Sue acknowledged the importance of family support to the band, particularly as an independent band, in the interview: Main sources of support? … the management from Toyota and everything … after winning Star Maker, that was really great, so they’ve really helped … and also family … you certainly need that support, because you can’t, you’ve got to get out there and do it, that’s the only way to do it … it’s very personal support in a lot of ways … we’re not at that stage where, we’re not at a bigger level where there’s plenty of money being thrown around by record companies, that sort of support.In acknowledging the role of family at home while the band tours, as well as the “personal support” given to the band, Sue binds the practices of individuals staying at home, minding kids and maintaining home life, to the discourse of family. She is also linking the practices to the band’s “independent” status and the lack of “money being thrown around by record companies” as the reason this support and other on the road, tour based work, is essential. Within Sue’s account here, and at other times during my fieldwork, there was a sense that she saw the need for family support as a sign of inadequacy, a sign that the band had not yet “made it” to the level where the support comes from record companies, and there will be money thrown around to support the activities of the band. This touches on a broader set of discourses that circulate in the country music community about professionalism and amateurism, which are also linked to ideas about family. While the foregrounding of family has value within the field of country music, there is something else going on here. A division is often drawn between “commercial” and “creative” endeavours in Australian country music. By linking practices involving kin and discourses of family, Bob Corbett and the Roo Grass Band position themselves as authentic, or real, grass roots, and with creative freedom, in contrast to being creatively constrained or selling out. Within this division, a reliance on one’s family can be understood in some ways as a rejection of the commercial, business networks of country music. In the case of Sue’s account above there is a sense that it is also a way of negotiating success when you do not have access to a record label or other big business support, which may seem the easier route. Sue’s view differs somewhat from Bob’s in this respect. Bob often expressed pride in the fact that they are “doing it on their own” and boasting an independent DIY model of music business (for example through ticketing, tour organisation and production); a business model that relies on the support of their family, but which is respected and valued within Australian country music. ConclusionArtists such as Bob Corbett and the Roo Grass Band all occupy “positions” in the field of Australian country music, and the discourses of “commercial”, “creative”, and “authentic” all work to categorise artists, and their position in the field. Economic and material circumstances limit, enable or influence the decisions to involve families or not: for Bob, a desire to remain in control of his creative output and career, and the need to maximise income to feed his family makes DIY ticketing, and taking his mum and friends on the road a good choice. But these material factors work with symbolic and cultural factors, in the game of cultural legitimisation about what it is to be a country music artist. The way in which Bob and the band invoked particular discourses of family, loyalty, fun and enjoyment, to talk about the on-the-ground practices of having family involved (or not) in their working lives as musicians is part of the work these bands and artists are doing to represent themselves to the country music community; they are attempting to establish themselves as adequately, legitimately and authentically “country”. In the process they are also shaping what it is to be a country music artist and what is valued within the field—in this case “family”. The constant struggles over what country music is, what is “authentic” country and what represents success, are struggles over the “schemata of classification … which construct social reality” (Bourdieu 20). Bob Corbett and the Roo Grass Band are using strategies in this struggle, in this case the strategies link practices involving kin to discourses of honesty and openness by collapsing public and private, heritage and tradition through the family band, and authenticity, professionalism, and success in the way family support can limit the need to rely on record labels and big business.

The seasonal periodicity of hydrology, physical and chemical water quality parameters and phytoplanktonic assemblages was studied at two sites in a large tropical Australian riverine impoundment. This study, the first in the lower Fitzroy River at Rockhampton, occurred between August 1990 and November 1993. It covered extremes in riverine flow conditions including major flooding and drought.

The annual flow regime was characterized by major flows in the "wet" season (summer and autumn) and greatly reduced or no flow in the "dry" season of winter, spring and sometimes early summer. Consequently, the thermal regime at both of the study sites was divided into two phases. The first was a phase of water column heating in the late winter to early summer. Features of this heating phase were long term stratification with progressive epilimnetic deepening, high pH, regular occurrence of epilimnetic oxygen supersaturation and decreased or undetectable levels of oxidized nitrogen in the surface layer. Hypolimnetic anoxia was recorded late in this phase. The second, between substantial wet season inflows and late winter was characterized by nutrient rich inflows and water column cooling and mixing.

Distinct interannual differences occurred in the volume, source and timing of inflows and subsequent water chemistry. In 1991, conductivity, water clarity, filterable reactive phosphorus (FRP) and pH increased markedly following major flooding from northern tributaries, while oxidized nitrogen decreased. This was in marked contrast to the drier years of 1992 and 1993 where turbidity and oxidized nitrogen were higher during the initial post-flood period and conductivity and FRP were lower. Extremes of mostly abiogenic turbidity (range 1.6 to 159 NTU) were a feature of the light climate. Ratios of euphotic depth/mixing depth below 0.3 occurred in early 1992 and 1993.

Steep gradients in the physical and chemical environment were paralleled by variations in the phytoplankton. Algal biomass (as chlorophyll a) at Site 1, midstream opposite the water intake for the city of Rockhampton, ranged from 1.5 to 56.6 ug L-1. The vertical water column distribution of chlorophyll was variable with assemblages normally dominated by phytoflagellates and various species of cyanoprokaryotes. There was also higher relative abundance of chlorophyll a (reflecting increasing dominance of cyanoprokaryotes) in the latter half of the year and at the lower end of light availability. The specific vertical water column positioning with respect to light and temperature is shown for assemblages dominated by the genera Anabaena, Aphanizomenon and Cylindrospermopsis.

The most striking aspect of the phytoplankton was the long term dominance of cyanoprokaryotes and the species richness (particularly that of cyanoprokaryotes) when compared with the dearth of information to date on other tropical rivers. Seasonal successions were varied. Regularly occurring assemblages were cyanoprokaryotes (Oscillatoriales), euglenophytes or non-flagellated chlorophytes during flows followed by flagellated chlorophytes and then cyanoprokaryotes (Nostocales) during the dry season. Genera present indicated highly eutrophic conditions. Hierarchical agglomerative clustering of phytoplankton data and comparison with a principal components analysis of corresponding environmental data were used to demonstrate the linkage between steep environmental gradients and variation in the phytoplankton assemblage. The specific environmental conditions associated with the success of various species were also analysed and presented. Using the above information, a two-part model was proposed which predicts the most likely genera of phytoplankton with respect to multidimensional environmental gradients. This model covers a wide gamut of conditions varying from highly variable lotic to lentic environments.

As Cylindrospermopsis raciborskii was considered a most important species in relation to the quality of the water supply for Rockhampton, the physical, chemical and biotic conditions prior to and during a bloom of this species are described. A number of possible grazers of C. raciborskii were identified with a view to future biomanipulation. One of these, the large ciliate, Paramecium cf. caudatum was found to be an effective grazer of toxic straight C. raciborskii in the laboratory.

This study is unique in that it analyses the impact of episodic events (eg. major flooding) on the subsequent phytoplankton in the lower Fitzroy River. The model relating phytoplankton to multidimensional environmental gradients provides great information for use in management, particularly in relation to the prediction of toxic algal blooms.

Introduction: The Mackay campus of Central Queensland University (CQU) celebrated its tenth birthday on the 19th April, 1997. The focus of this occasion was a dinner attended by members of the Mackay Advisory Committee who had been involved in the establishment of the campus.

The incorporation of legumes into crop rotations has been suggested as a strategy to address declining soil fertility, especially of nitrogen (N), in Central Queensland cropping systems. However, traditional methods to determine the contribution made by legumes to soil N are flawed in that usually only the above ground biomass (AGB) or at best macro root tissues are assessed. Furthermore crops regularly experience soil water deficits in this environment, but the impact this has on the contribution made to soil fertility by legumes is poorly documented.

A published ¹⁵N foliar labelling methodology that accurately estimates legume below ground biomass N (BGB-N), was adapted under polyhouse conditions and verified in the field for lab lab, lucerne and siratro. For the legumes investigated, labelled macro root tissue at a depth of 10-20 cm was representative of recoverable root tissue (all > 500 um) throughout a 60 cm soil profile. A protocol was established that reliably estimated the ¹⁵N content of soil enriched by the labelled root system to within a 95% confidence interval.

N₂ fixation in symbioses which translocate fixed N as amides from their nodules are reported to have a greater tolerance to water stress than that in symbioses which export ureides. The impact of water stress on N₂ fixation and the distribution of biomass and N between above and below ground compartments was therefore studied for two commercially important legumes: mungbean (a ureide exporter) and peanut (an amide exporter). Under glasshouse conditions, drought had no effect on mungbean BGB-N as a proportion of legume N (AGB-N + BGB-N) (35%) whereas the proportion of peanut N as BGB-N increased from 33 % under optimal conditions to 44% (P<0.05) under terminal drought. Legume N and N derived from atmospheric N2 (Ndfa), including BGB-N and BGB Ndfa was significantly greater than estimates based on AGB-N alone. Under drought, whole plant Ndfa was twice that of values based on AGB-N alone. The proportion of cereal crop N derived from legume BGB-N (27%) was significantly greater than that derived from AGB-N (20%). The proportion of mungbean N derived from atmospheric N₂ (%Ndfa) was 51% under optimal soil water conditions but declined to 20 and 12% under the moderate and terminal droughts, respectively. Severe drought produced a small but significant reduction in N₂ fixation activity compared to optimally watered plants (%Ndfa decreased to 67 from 78%; P<0.05). Moderate drought had not significant effect on %Ndfa compared to optimally watered plants (78 and 75%Ndfa, respectively).

Similar trends to those reported in the glasshouse trial were observed under field conditions, with significantly greater contributions by mungbean and peanut to soil N fertility and cereal crops documented than reported previously for a range of grain and pasture legumes used in Central Queensland cropping systems. Droughted legumes increased the proportion of BGB-N at depth (20-60 cm), with greater increases by peanut. Despite drought induced decreases in mungbean and peanut %Ndfa (at 59 and 32%, respectively, of irrigated plants), droughted mungbean and peanut %Ndfa was still substantial (30 and 53%, respectively). Droughted whole mungbean and peanut Ndfa was estimated at 10 and 21 kg N/ha, respectively. However, net N balance was nevertheless neutral to negative for mungbean when N exported in harvested grain was considered. The estimates of Ndfa were three fold higher than that based on AGB-N only, and were consistent with the thesis that legumes possessing an amide exporting symbiosis offer significantly greater potential to improve soil N fertility in the region. The drought survival mechanisms exhibited by legumes is also a factor determining whether or not accumulated N and N₂ fixation were maintained under increased soil water deficit and when a net contribution to soil N stores was likely.

"Pisonia grands R. Br. (Nyctaginaceae) is a large tropical tree whose distribution is restricted to coral cays, in particular those with high seasonal nesting seabird populations. These trees are often the dominant plant species found on coral cays. This is the case for the chosen study site on North West Island, a coral cay which lies off the Central Queensland coast within the Mackay Capricorn section of the Great Barrier Reef. Coral cays are almost entirely composed of coral rubble and sand and as a result the substrate pH (c. 9.0) and many ions are found as insoluble salts. The high pH, abundance of calcium, lack of water and high seasonal input of nitrates from nesting seabirds, are possible influences on the biosynthesis of oxalates which are found in high concentrations in P. grandis. The aims of this study are twofold. The first aim was to investigate the influence of environmental factors, such as pH and nitrate concentration, on the biosynthesis of oxalate in Pisonia grandis leaf. The second aim was to purify and characterise the enzyme glycolic acid oxidase (E.C. 1.1.3.1) (GAO), an enzyme involved in the biosynthesis of oxalate..." --abstract.. Pisonia grandis R. Br. (Nyctaginaceae) is a large tropical tree whose distribution is restricted to coral cays, in particular those with high seasonal nesting seabird populations. These trees are often the most dominant plant species found on coral cays. This is the case for the chosen study site on North West Island, a coral cay which lies off the Central Queensland coast within the Mackay Capricorn section of the Great Barrier Reef. Coral cays are almost entirely composed of coral rubble and sand and as a result the substrate pH is high (c. 9.0) and many ions are found as insoluble salts. The high pH, abundance of calcium, lack of water and high seasonal input of nitrates from nesting seabirds, are possible influences on the biosynthesis of oxalates which are found in high concentrations in P. grandis. The aims of this study were twofold. The first aim was to investigate the influence of environmental factors, such as pH and nitrate concentration, on the biosynthesis of oxalate in Pisonia grandis leaf. The second aim was to purify and characterise the enzyme glycolic acid oxidase (E.C. 1.1 .3.1) (GAO), an enzyme involved in the biosynthesis of oxalate. P. grandis was grown in a hydroponic system which was constructed in a glasshouse. The effect of variations in light intensity, pH and the concentrations of nitrate, calcium and sodium chloride in the nutrient sol ution on leaf oxalate concentration was investigated. A small diurnal variation in leaf soluble oxalate concentration was observed (O.5mmol/g DW at 07:00hrs and 0.62 mmol/g/DW at 19:00hrs) which was consistent with the notion that an intermediate in the formation of oxalate was derived from photosynthesis or photorespiration. In all other experimental regimes leaf oxalate concentrations were shown to vary in response to changes in the excess cation content of the leaves. These hydroponic studies suggested that changes in leaf excess cation concentration, and associated changes in intracellular pH, stimulate changes in the biosynthesis of oxalate in Pisonia. GAO was isolated to purity from the leaves of P. grandis and was found to be similar to GAO from other sources. The holoenzyme was found to be a hexamer (M.Wt. 250000) of subunits with molecular weight 44000. In vitro, with glycolate substrate, GAO had a pH optima of 7.0 and a Km of O.4mM. The enzyme exhibited partial competitive inhibition by oxalate (Ki 2.75mM) and was irreversibly inhibited by phydroxymercuribenzoate. Phenyllactate and iodoacetate did not inhibitthe enzyme preparation. These studies were repeated for glyoxylate and lactate as the enzyme substrates. The pH optima determined for GAO in vitro with glycolate and glyoxylate substrates, in conjunction with the pH optima reported for aminotransferase enzymes, supports the notion that leaf oxalate participates in a biochemical pH stat within the leaves of Pisonia grandis.

Two new programs at Geoscience Australia are providing trusted, high-quality science to support decision making and the Australian resources industry. The Trusted Environmental and Geological Information program will provide baseline precompetitive data in the Cooper, Adavale, north Bowen and Galilee basin regions. A repository of information is being developed in collaboration with CSIRO, including new geological and environmental assessments, to accelerate development in the sectors of petroleum, mineral, hydrogen and carbon capture and storage, while simultaneously providing opportunities to understand the potential hazards, risk and impacts of these resources being developed. The Data Driven Discoveries program is combining new and old data to better understand the underexplored Adavale Basin in central-western Queensland. The program will undertake chemical composition analyses to support the correlation of geological layers, collate and reprocess historical seismic data, acquire new seismic reflection data, and undertake stratigraphic research drilling to provide a more detailed understanding of basin architecture and the resource potential of the Adavale Basin. An overview of the Trusted Environmental and Geological Information and Data Driven Discoveries programs, initial results, and planned acquisition, will show how these complementary programs will contribute to streamlined regulation and approval processes, the low emissions agenda, and responsible resource development in key basins regions across Australia.
