7519-675: The next six longest rivers of Australia (the Murrumbidgee , Darling , Lachlan , Warrego and Paroo Rivers ). Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin , which covers about one-seventh the area of Australia. It is widely considered Australia's most important irrigated region. The Murray rises in the Australian Alps , draining the western side of Australia's highest mountains, then meanders northwest across Australia's inland plains, forming
7622-519: 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
7725-474: The patterns of the river's natural flow from the original winter-spring flood and summer-autumn dry to the present low level through winter and higher during summer. These changes ensured the availability of water for irrigation and made the Murray Valley Australia's most productive agricultural region, but have seriously disrupted the life cycles of many ecosystems both inside and outside the river, and
7828-470: 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
7931-456: The remaining length of the Murray to finally reach Lake Alexandrina and the river's mouth. The vicinity of the Murray Mouth was explored more thoroughly by Captain Collet Barker in 1831. The first three settlers on the Murray River are known to have been James Collins Hawker (explorer and surveyor) along with Edward John Eyre (explorer and later Governor of Jamaica ) plus E.B. Scott (onetime superintendent of Yatala Labour Prison ). Hawker
8034-426: The river channel is unusually narrow), before entering into the proper Murray River channel again. The primary result of the Cadell Fault – that the west-flowing water of the Murray River strikes the north-south fault and diverts both north and south around the fault in the two main channels (Edward and ancestral Goulburn) in addition to a fan of small streams, and regularly floods a large amount of low-lying country in
8137-556: The river promoted an expansion of farming and led ultimately to the development of irrigation areas (including the Murrumbidgee Irrigation Area ). In 1915, the three Murray states – New South Wales, Victoria, and South Australia – signed the River Murray Agreement which proposed the construction of storage reservoirs in the river's headwaters as well as at Lake Victoria near the South Australian border. Along
8240-724: The river where Albury now stands in 1824: Hume named it the Hume River after his father. In 1830, Captain Charles Sturt reached the river after travelling down its tributary the Murrumbidgee River and named it the Murray River in honour of the then British Secretary of State for War and the Colonies , Sir George Murray , not realising it was the same river that Hume and Hovell had encountered further upstream. Sturt continued down
8343-595: The river's length. There are widespread concerns that the river will be unusably salty in the medium to long term – a serious problem given that the Murray supplies 40 per cent of the water supply for Adelaide . Efforts to alleviate the problems have proceeded but disagreement between various groups has hampered progress. Introduced fish species such as carp , gambusia , weather loach , redfin perch , brown trout , and rainbow trout have also had serious negative effects on native fish. The most pernicious are carp, which have contributed to environmental degradation of
8446-527: The river. The primary purpose of this is to provide habitat for fish species whose breeding grounds and shelter were eradicated by the removal of the snags. Author E.J. Brady chronicled an eventful journey downriver in a small motor boat from Albury to the coast in 1911 in River Rovers. The volume and value of river trade made Echuca Victoria's second port and in the decade from 1874 it underwent considerable expansion. By this time up to thirty steamers and
8549-470: The south-east before emptying into the Great Australian Bight (often referenced on Australian maps as the Southern Ocean ) through the Murray Mouth , 10 km (6.2 mi) east of Goolwa South . Despite discharging considerable volumes of water at times, particularly before the advent of large-scale river regulation , the waters at the Murray Mouth are almost invariably slow and shallow. As of 2010 ,
8652-439: 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
8755-444: The southern part of Queensland. The Murray carries only a small fraction of the water of comparably sized rivers in other parts of the world, and with great annual variability of its flow. It has dried up completely during extreme droughts on three occasions since official record-keeping began. More often, a sandbar formed at the mouth and stopped the flow. The Murray is the border between New South Wales and Victoria – specifically at
8858-488: 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
8961-578: The state's upper house with the balance of power controlled by a variety of minor parties and independents. 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
9064-434: The stretch downstream of Mildura , Lock 15 at Euston and Lock 26 at Torrumbarry . Construction of the remaining weirs purely for navigation purposes was abandoned in 1934. The last lock to be completed was Lock 15, in 1937. Lock 11, just downstream of Mildura, creates a 100-kilometre (62 mi) long lock pool that aided irrigation pumping from Mildura and Red Cliffs . Each lock has a navigable passage next to it through
9167-550: The top of the bank of the Victorian side of the river. In a 1980 judgement, the High Court of Australia ruled on the question as to which state had jurisdiction in the unlawful death of a man who was fishing by the river's edge on the Victorian side of the river. This boundary definition can be ambiguous, since the river changes its course over time, and some of the river banks have been modified. For 11 km (6.8 mi) west of
9270-468: The town of Murray Bridge, formerly called Edwards Crossing. To distinguish this bridge from the many others that span the Murray River, this bridge is known as Murray River road bridge, Murray Bridge Tolls applied on South Australian ferries until abolished in November 1961. Small-scale pumping plants began drawing water from the Murray in the 1850s and the first high-volume plant was constructed at Mildura in 1887. The introduction of pumping stations along
9373-520: 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
9476-409: The weir, which is opened during periods of high river flow, when there is too much water for the lock. The weirs can be completely removed, and the locks completely covered by water during flood conditions. Lock 11 is unique in that the lock was built inside a bend of the river, with the weir in the bend itself. A channel was dug to the lock, creating an island between it and the weir. The weir is also of
9579-400: The women settled on the shore, only to suffer bad luck with fishing, being plagued by a water fiend known as Muldjewangk . They later moved to a more suitable spot at the site of present-day Ashville . The twin summits of Mount Misery are said to be the remnants of his rafts; they are known as Lalangengall or the two watercraft . This story of a hunter pursuing a Murray cod that carved out
9682-447: 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
9785-597: Was dammed by the southern end of the fault to create a natural lake. The Murray River flowed to the north around the Cadell Fault, creating the channel of the Edward River which exists today and through which much of the Murray's waters still flow. Then the natural dam on the Goulburn River failed, the lake drained, and the Murray changed its course to the south and started to flow through the smaller Goulburn River channel, creating "The Barmah Choke" and "The Narrows" (where
9888-492: 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
9991-550: 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
10094-428: Was launched as a mission steamer, replacing an earlier steam launch, also named Etona , which had been operating on the Murray since 1891. The vessel was based at Murray Bridge , and operated between Goolwa and the Victorian border, stopping at towns such as Mannum , Morgan and Renmark as well as isolated settlements and workcamps. The forepart of the vessel was used a chapel fitted with an altar and organ, with
10197-461: 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
10300-470: 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
10403-559: 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
10506-455: Was welcomed by pastoralists who had been suffering from a shortage of transport due to the demands of the gold fields. By 1860 a dozen steamers were operating in the high water season along the Murray and its tributaries. Once the railway reached Echuca in 1864, the bulk of the woolclip from the Riverina was transported via river to Echuca and then south to Melbourne. The steam paddleship Etona
10609-769: 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
