The Letters Patent , which used the enabling provisions of the South Australia Act 1834 to fix the boundaries of the Province of South Australia, provided that "nothing in those our Letters Patent shall affect or be construed to affect the rights of any Aboriginal Natives of the said Province to the actual occupation and enjoyment in their own Persons or in the Persons of their Descendants of any Lands therein now actually occupied or enjoyed by such Natives." Although
7425-650: The only source of fresh water through much of inland Australia. The basin underlies 22% of the Australian continent, including most of Queensland , the south-east corner of the Northern Territory , north-eastern South Australia , and northern New South Wales . It is 3000 metres (9800 feet) deep in places and is estimated to contain 64,900 cubic kilometres (15,600 cubic miles) of groundwater . The Great Artesian Basin Coordinating Committee (GABCC) coordinates activity between federal, state/territory and local levels of government and community organisations. This area
7524-498: The opal industry attracted Aboriginal people because of the level of workplace autonomy it provided", and it also accommodated their cultural practices. While opal mining around the town had slumped in the early 1940s, it picked up after a local Aboriginal woman, Tottie Bryant, discovered a large deposit in 1945. In August 1956 at the 'Eight Mile' opal field, the Olympic Australis opal was found approximately 30 feet below
7623-461: The opal mines, which were expanding rapidly, and following World War II many refugees, veterans, and immigrants from Southern and Eastern Europe found employment in the mines as well. At some points in the post-war period, up to 60 per cent of miners at Coober Pedy had Southern or Eastern European ancestry. Aboriginal people were also employed in the industry from the 1940s. A 2016 thesis by M. Harding suggests "the small-scale and informal nature of
7722-534: The patent guaranteed land rights under force of law for the indigenous inhabitants, it was ignored by the South Australian Company authorities and squatters. Despite strong reference to the rights of the native population in the initial proclamation by the Governor, there were many conflicts and deaths in the Australian Frontier Wars in South Australia. Survey was required before settlement of
7821-481: The province, and the Colonization Commissioners for South Australia appointed William Light as the leader of its 'First Expedition', tasked with examining 1500 miles of the South Australian coastline and selecting the best site for the capital, and with then planning and surveying the site of the city into one-acre Town Sections and its surrounds into 134-acre Country Sections. Eager to commence
7920-410: The region's low rainfall, the high cost of water, and lack of topsoil. The harsh summer desert temperatures mean that many residents prefer to live in caves bored into the hillsides (known as " dugouts "). A standard three-bedroom cave home with lounge, kitchen, and bathroom can be excavated out of the rock in the hillside for a similar price to building a house on the surface. However, dugouts remain at
8019-461: The rock formations from relatively high ground near the eastern edge of the basin (in Queensland and New South Wales) and very gradually flows toward the south and west. A much smaller amount enters along the western margin in arid central Australia, flowing to the south and east through the permeable sandstone, at a rate of one to five metres per year. Discharge water eventually exits through
8118-439: The south-east by Victoria , and to the south by the Great Australian Bight . The state comprises less than 8% of the Australian population and ranks fifth in population among the six states and two territories. The majority of its people reside in greater Metropolitan Adelaide. Most of the remainder are settled in fertile areas along the south-eastern coast and River Murray . The state's colonial origins are unique in Australia as
8217-441: The state has a Mediterranean climate , while the rest of the state has either an arid or semi-arid climate . South Australia's main temperature range is 29 °C (84 °F) in January and 15 °C (59 °F) in July. The highest maximum temperature ever recorded was 50.7 °C (123.3 °F) at Oodnadatta on 2 January 1960, which is the highest official temperature recorded in Australia. The lowest minimum temperature

Local government in South Australia is established by the Constitution Act 1934 (SA), the Local Government Act 1999 (SA), and the Local Government (Elections) Act 1999 (SA). South Australia contains 68 councils and 6 Aboriginal and outback communities . Local councils, elected on
8415-583: The total output has dropped to 1,500 megalitres (1,200 acre⋅ft) per day. This included just under 2,000 freely-flowing bores and more than 9,000 that required mechanical power to bring water to the surface. Many bores are unregulated or abandoned, resulting in considerable water wastage. These problems have existed for many decades, and in January 2007 the Australian Commonwealth Government announced additional funding in an attempt to bring them under control. However, many of
8514-480: The town's history. Coober Pedy is also renowned for its below-ground dwellings, called " dugouts ", which are built in this fashion due to the scorching daytime heat. The name "Coober Pedy" is thought to derive from the Kokatha- Barngarla term kupa-piti , which translates to "whitefellas' hole", but in 1975 the local Aboriginal people of the town adopted the name Umoona , which means "long life" and
8613-600: The upper house, the Legislative Council, remained the exclusive domain of property owners until the Labor government of Don Dunstan managed to achieve reform of the chamber in 1973. Property qualifications were removed and the Council became a body elected via proportional representation by a single state-wide electorate. Since the following 1975 South Australian state election , no one party has had control of
8712-625: The words in the Kokatha language , kupa piti , usually translated as "whitefella" and "hole in the ground", or guba bidi , "white man's holes", relating to white people's mining activities. Further investigation into the words by linguists shows that kupa may have originated from the Parnkalla language and that piti may be the Kokatha word specifically created for "quarry" (a white man's activity). In 1858, Scottish-born John McDouall Stuart
8811-447: The world. Opal was first discovered near the town in 1915, and the town became the site of an opal rush, enticing immigrants from southern and eastern Europe in the aftermath of World War II . Higher education and research in Adelaide forms an important part of South Australia's economy. The South Australian Government and educational institutions have attempted to position Adelaide as Australia's education hub and have marketed it as
8910-623: Was below sea level , the sandstone was covered by a layer of marine sedimentary rock, which formed a confining layer that trapped water in the sandstone aquifer. The eastern edge of the basin was uplifted when the Great Dividing Range formed. The other side was created from the landforms of the Central Eastern Lowlands and the Great Western Plateau to the west. Most recharge water enters
9009-495: Was closed in June 2014. It was sold to Cu-River Mining who reopened the mine in 2016. In 2013, a potentially significant tight oil (oil trapped in oil-bearing shales) resource was found near the outskirts of Coober Pedy in the Arckaringa Basin . This resource was estimated to hold between 3.5 and 223 billion barrels (560 × 10 ^ and 35,450 × 10 ^ m) of oil, providing the potential for Australia to become

9207-497: Was formally constituted as a penal colony. Although South Australia was constituted such that convicts could never be transported to the Province, some emancipated or escaped convicts or expirees made their own way there, both prior to 1836, or later, and may have constituted 1–2% of the early population. The plan for the province was that it would be an experiment in reform, addressing the problems perceived in British society. There
9306-559: Was founded. The guiding principle behind settlement was that of systematic colonisation , a theory espoused by Edward Gibbon Wakefield that was later employed by the New Zealand Company . The goal was to establish the province as a centre of civilisation for free immigrants, promising civil liberties and religious tolerance. Although its history has been marked by periods of economic hardship, South Australia has remained politically innovative and culturally vibrant. Today, it
9405-468: Was the first Australian colony not to have an official state religion, and the colony became attractive to people who had experienced religious discrimination, including Methodists and Unitarians . South Australia also had thousands of Prussian Old Lutheran immigrants, some of whom established their own form of Lutheranism. As a result, the Lutheran Church of Australia remains separate from
9504-407: Was the first European explorer to pass near the site of Coober Pedy. On 1 February 1915, Wille Hutchison discovered the first opal in the area, after which the town was established. Opal miners started moving in around 1916. In 1920, five years later, a meeting settled on the name of Coober Pedy, when a post office was established. In July 1975, the local Aboriginal people of Coober Pedy adopted
9603-474: Was to be religious freedom and no established religion. Sales of land to colonists created an Emigration Fund to pay the costs of transferring a poor young labouring population to South Australia. In early 1838 the colonists became concerned after it was reported that convicts who had escaped from the eastern states may make their way to South Australia. The South Australia Police was formed in April 1838 to protect
9702-513: Was upgraded to AAA by Standard & Poor's in September 2004 and to AAA by Moody's in November 2004, the highest credit ratings achievable by any company or sovereign. The state had previously lost these ratings in the State Bank collapse. However, in 2012 Standard & Poor's downgraded the state's credit rating to AA+ due to declining revenues, new spending initiatives and a weaker than expected budgetary outlook. South Australia receives
9801-786: Was −8.2 °C (17.2 °F) at Yongala on 20 July 1976. The region's overall dry weather is owed to the Australian High on the Great Australian Bight. As of 2016, South Australia had 746,105 people employed out of a total workforce of 806,593, giving an unemployment rate of 7.5%. South Australia's largest employment sector is health care and social assistance, making up 14.8% of the state's total employment, followed by retail (10.7%), education and training (8.6%), manufacturing (8%), and construction (7.6%). South Australia's economy relies on exports more than any other state in Australia. South Australia's credit rating
