75-503: The Barrier Ranges comprise the whole system of ranges and ridges associated with the main watershed named the Main Barrier Range - including Coko Range, Floods Range, Slate Range, Robe Range, Mundi Mundi Range, Coonbaralba Range and Mount Darling Range. The city of Broken Hill lies within these ranges. The ranges is oriented in a roughly north-south direction, east of the border between New South Wales and South Australia . It

150-668: A Learning City . The number of international students studying in Adelaide has increased rapidly in recent years to 30,726 in 2015, of which 1,824 were secondary school students. Foreign institutions have been attracted to set up campuses to increase its attractiveness as an education hub. Adelaide is the birthplace of three Nobel laureates, more than any other Australian city : physicist William Lawrence Bragg and pathologists Howard Florey and Robin Warren , all of whom completed secondary and tertiary education at St Peter's College and

225-421: A fire starter. The exact mode of formation of flint is not yet clear, but it is thought that it occurs as a result of chemical changes in compressed sedimentary rock formations during the process of diagenesis . One hypothesis is that a gelatinous material fills cavities in the sediment, such as holes bored by crustaceans or molluscs and that this becomes silicified . This hypothesis would certainly explain

Councils have the power to raise revenue for their activities, which is mostly achieved through "council rates",

375-735: A tax based on property valuations. Council rates make up about 70% of council revenue, but account for less than 4% of total taxes paid by Australians. As at December 2021 the population of South Australia was 1,806,599. A majority of the state's population lives within Greater Adelaide 's metropolitan area which had an estimated population of 1,333,927 in June 2017. Other significant population centres include Mount Gambier (29,505), Victor Harbor - Goolwa (26,334), Whyalla (21,976), Murray Bridge (18,452), Port Lincoln (16,281), Port Pirie (14,267), and Port Augusta (13,957). At

450-662: A temporary settlement at Kingscote , Kangaroo Island , on 26 July 1836, five months before Adelaide 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

525-533: A trigger, strikes a hinged piece of steel (" frizzen ") at an angle, creating a shower of sparks and exposing a charge of priming powder. The sparks ignite the priming powder and that flame, in turn, ignites the main charge, propelling the ball, bullet, or shot through the barrel. While the military use of the flintlock declined after the adoption of the percussion cap from the 1840s onward, flintlock rifles and shotguns remain in use amongst recreational shooters. Flint and steel used to strike sparks were superseded in

600-432: Is a state in the southern central part of Australia . With a total land area of 984,321 square kilometres (380,048 sq mi), it is the fourth-largest of Australia's states and territories by area, which includes some of the most arid parts of the continent, and with 1.8 million people it is the fifth-largest of the states and territories by population. This population is the second-most highly centralised in

675-478: Is also the world's fourth-largest remaining copper deposit, and the world's fifth largest gold deposit. There was a proposal to vastly expand the operations of the mine, making it the largest open-cut mine in the world, but in 2012 the BHP Billiton board decided not to go ahead with it at that time due to then lower commodity prices. The remote town of Coober Pedy produces more opal than anywhere else in

750-679: Is an area of slightly higher ground lying between the lower lands along the Darling River , and lower ground in South Australia. The Barrier Ranges contains a number of mineral deposits, most notably Broken Hill. It was reported in October 1856 that, 'within the last year or two numerous sheep-stations have been opened in the Barrier Ranges, affording a reasonable prospect, not only of increased pastoral wealth, but also of

825-412: Is commonly included in survival kits . Ferrocerium is used in many cigarette lighters, where it is referred to as "a flint". Flint's utility as a fire starter is hampered by its property of uneven expansion under heating, causing it to fracture, sometimes violently, during heating. This tendency is enhanced by the impurities found in most samples of flint that may expand to a greater or lesser degree than

900-602: Is flanked by the Southern Ocean , but official international consensus defines the Southern Ocean as extending north from the pole only to 60°S or 55°S, at least 17 degrees of latitude further south than the most southern point of South Australia. Thus the south coast is officially adjacent to the south-most portion of the Indian Ocean. See Southern Ocean: Existence and definitions . The southern part of

975-538: Is known for its fine wine and numerous cultural festivals. The state's economy is dominated by the agricultural, manufacturing and mining industries. Evidence of human activity in South Australia dates back as far as 20,000 years, with flint mining activity and rock art in the Koonalda Cave on the Nullarbor Plain . In addition wooden spears and tools were made in an area now covered in peat bog in

1050-577: Is one of the primary materials used to define the Stone Age . During the Stone Age, access to flint was so important for survival that people would travel or trade long distances to obtain the stone. Grime's Graves was an important source of flint traded across Europe. Flint Ridge in Ohio was another important source of flint, and Native Americans extracted the flint from hundreds of quarries along

1125-560: Is the Mount Lofty - Flinders Ranges system, which extends north about 800 kilometres (500 mi) from Cape Jervis to the northern end of Lake Torrens . The highest point in the state is not in those ranges; Mount Woodroffe (1,435 metres (4,708 ft)) is in the Musgrave Ranges in the extreme northwest of the state. The south-western portion of the state consists of the sparsely inhabited Nullarbor Plain , fronted by

1200-739: The Adelaide Hills . Tomatoes , capsicums , cucumbers , brassicas , lettuce and carrots are grown on the Northern Adelaide Plains at Virginia . Almonds , citrus and stone fruit are grown in the Riverland . Potatoes , onions and carrots are grown in the Murray Mallee region. Potatoes are grown on Kangaroo Island . South Australia produces more than half of all Australian wine, including almost 80% of Australia's premium wines. South Australia has

1275-800: The Dutch ship the Gulden Zeepaert , captained by François Thijssen , examined and mapped a section of the coastline as far east as the Nuyts Archipelago . Thijssen named the whole of the country eastward of the Leeuwin "Nuyts Land", after a distinguished passenger on board; the Hon. Pieter Nuyts , one of the Councillors of India . The coastline of South Australia was first mapped by Matthew Flinders and Nicolas Baudin in 1802, excepting

1350-680: The Governor of South Australia as his representative. It is a state of the Commonwealth of Australia . The bicameral Parliament of South Australia consists of the lower house known as the House of Assembly and the upper house known as the Legislative Council . General elections are held every four years, the last being the 2022 election . Initially, the Governor of South Australia held almost total power, derived from

1425-578: The Hornsdale Wind Farm in South Australia's Mid-North region. At the time of construction in late 2017, it was billed as the largest lithium-ion battery in the world. The Olympic Dam mine near Roxby Downs in northern South Australia is the largest deposit of uranium in the world, possessing more than a third of the world's low-cost recoverable reserves and 70% of Australia's. The mine, owned and operated by BHP , presently accounts for 9% of global uranium production. The Olympic Dam mine

1500-787: The Jurassic deposits of the Kraków area and Krzemionki in Poland, as well as of the Lägern ( silex ) in the Jura Mountains of Switzerland. In 1938, a project of the Ohio Historical Society , under the leadership of H. Holmes Ellis began to study the knapping methods and techniques of Native Americans . Like past studies, this work involved experimenting with actual knapping techniques by creation of stone tools through

1575-744: The Riverland and the Adelaide Hills . See South Australian wine . South Australia has boundaries with every other Australian mainland state and territory except the Australian Capital Territory and the Jervis Bay Territory .

1650-482: The South Australia Act 1834 ( Foundation Act ), which empowered His Majesty to erect and establish a province or provinces in southern Australia. The act stated that the land between 132° and 141° east longitude and from 26° south latitude to the southern ocean would be allotted to the intended colony, and it would be convict-free. In contrast to the rest of Australia, terra nullius did not apply to

1725-525: The University of Adelaide . Adelaide is home to research institutes, including the Royal Institution of Australia , established in 2009 as a counterpart to the two-hundred-year-old Royal Institution of Great Britain. Most of the research organisations are clustered in the Adelaide metropolitan area: South Australia is a constitutional monarchy with King Charles III as sovereign, and

1800-534: The 2016 census, 78.2% of the population spoke only English at home. The other languages most commonly spoken at home were Italian (1.7%), Standard Mandarin (1.7%), Greek (1.4%), Vietnamese (1.1%), and Cantonese (0.6%). At the 2016 census , overall 53.9% of responses identified some variant of Christianity . 9% of respondents chose not to state a religion. The most commonly nominated responses were 'No Religion' (35.4%), Catholicism (18%), Anglicanism (10%) and Uniting Church (7.1%). South Australia

1875-417: The 2016 census, the most commonly nominated ancestries were: 28.9% of the population was born overseas at the 2016 census. The five largest groups of overseas-born were from England (5.8%), India (1.6%), China (1.5%), Italy (1.1%) and Vietnam (0.9%). 2% of the population, or 34,184 people, identified as Indigenous Australians ( Aboriginal Australians and Torres Strait Islanders ) in 2016. At

1950-580: The 2020–21 financial year. This was the first time since the Australian Bureau of Statistics began collecting data in 1990 that South Australia had outperformed the other states. The recovery was driven in part by growth in the agricultural sector, which increased its production by almost 24% thanks to the end of a drought. Wheat , barley , oats , rye , peas , beans , chickpeas , lentils and canola are grown in South Australia. Apples , pears , cherries and strawberries are grown in

2025-436: The 20th century by ferrocerium (sometimes referred to as "flint", although not true flint, " mischmetal ", "hot spark", "metal match", or "fire steel"). This human-made material, when scraped with any hard, sharp edge, produces sparks that are much hotter than obtained with natural flint and steel, allowing use of a wider range of tinders. Because it can produce sparks when wet and can start fires when used correctly, ferrocerium

2100-600: The City of Adelaide is currently located. The first immigrants arrived at Holdfast Bay (near the present day Glenelg ) in November 1836. The commencement of colonial government was proclaimed on 28 December 1836, now known as Proclamation Day . South Australia is the only Australian state to have never received British convicts. Another free settlement, Swan River colony was established in 1829 but Western Australia later sought convict labour, and in 1849 Western Australia

2175-641: The German Lutheran church to this day. South Australia was the location of the first Muslim mosque in Australia. Flint Flint , occasionally flintstone , is a sedimentary cryptocrystalline form of the mineral quartz , categorized as the variety of chert that occurs in chalk or marly limestone . Historically, flint was widely used to make stone tools and start fires . Flint occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones . Inside

2250-597: The Imperial Parliament enacted the Australian Colonies Government Act , which allowed for the election of representatives to each of the colonial legislatures and the drafting of a constitution to properly create representative and responsible government in South Australia. Later that year, propertied male colonists were allowed to vote for 16 members on a new 24 seat Legislative Council. Eight members continued to be appointed by

2325-468: The South East. Kangaroo Island was inhabited long before the island was cut off by rising sea levels . According to mitochondrial DNA research, Aboriginal people reached Eyre Peninsula 49,000-45,000 years ago from both the east (clockwise, along the coast, from northern Australia) and the west (anti-clockwise). The first recorded European sighting of the South Australian coast was in 1627 when

2475-509: The border on the ground in the 1920s. In 1863, that part of New South Wales to the north of South Australia was annexed to South Australia, by letters patent, as the "Northern Territory of South Australia", which became shortened to the Northern Territory on 6 July 1863 . The Northern Territory was handed to the federal government in 1911 and became a separate territory. According to Australian maps, South Australia's south coast

2550-520: The chalky-soil country of France, the British filled sandbags with flint and used these sandbags as breastworks. Flint pebbles are used as the media in ball mills to grind glazes and other raw materials for the ceramics industry. The pebbles are hand-selected based on colour; those having a tint of red, indicating high iron content, are discarded. The remaining blue-grey stones have a low content of chromophoric oxides and so are less deleterious to

2625-618: The cliffs of the Great Australian Bight . Features of the coast include Spencer Gulf and the Eyre and Yorke Peninsulas that surround it. The Temperate Grassland of South Australia is situated to the east of Gulf St Vincent . The principal industries and exports of South Australia are wheat, wine and wool. More than half of Australia's wines are produced in the South Australian wine regions which principally include Barossa Valley , Clare Valley , McLaren Vale , Coonawarra ,

2700-424: The coasts of South-East England or Western France, were calcined to around 1,000 °C (1,800 °F). This heating process both removed organic impurities and induced certain physical reactions, including converting some of the quartz to cristobalite . After calcination the flint pebbles were crushed and milled to a fine particle size. However, the use of flint has now been superseded by quartz . Because of

2775-477: The colony of New South Wales . Although the new colony included almost two-thirds of the continent, early settlements were all on the eastern coast and only a few intrepid explorers ventured this far west. It took more than forty years before any serious proposal to establish settlements in the south-western portion of New South Wales were put forward. On 15 August 1834, the British Parliament passed

2850-455: The colour of the ceramic composition after firing. Until recently calcined flint was also an important raw material in clay-based ceramic bodies produced in the UK. In clay bodies , calcined flint attenuates the shrinkage whilst drying, and modifies the fired thermal expansion. Flint can also be used in glazes as a network former. In preparation for use flint pebbles, frequently sourced from

2925-581: The community and enforce government regulations. Their principal role was to run the first temporary gaol, a two-room hut. The current flag of South Australia was adopted on 13 January 1904, and is a British blue ensign defaced with the state badge. The badge is described as a piping shrike with wings outstretched on a yellow disc. The state badge is believed to have been designed by Robert Craig of Adelaide's School of Design . The terrain consists largely of arid and semi-arid rangelands, with several low mountain ranges . The most important (but not tallest)

3000-579: The complex shapes of flint nodules that are found. The source of dissolved silica in the porous media could be the spicules of silicious sponges ( demosponges ). Certain types of flint, such as that from the south coast of England and its counterpart on the French side of the Channel , contain trapped fossilised marine flora. Pieces of coral and vegetation have been found preserved inside the flint similar to insects and plant parts within amber . Thin slices of

3150-485: The first in the world to allow women to stand for election. In 1897 Catherine Helen Spence was the first woman in Australia to be a candidate for political office when she was nominated to be one of South Australia's delegates to the conventions that drafted the constitution. South Australia became an original state of the Commonwealth of Australia on 1 January 1901. Although the lower house had universal suffrage,

3225-414: The flint, in a similar (but more time-consuming) way. These methods remain popular in woodcraft, bushcraft, and amongst people practising traditional fire-starting skills. A later, major use of flint and steel was in the flintlock mechanism , used primarily in flintlock firearms, but also used on dedicated fire-starting tools. A piece of flint held in the jaws of a spring-loaded hammer, when released by

3300-501: The government is the party or coalition that exerts a majority in the House of Assembly. The Legislative Council remained a predominantly conservative chamber elected by property owners. Women's suffrage in Australia took a leap forward – enacted in 1895 and taking effect from the 1896 colonial election , South Australia was the first government in Australia and only the second in the world after New Zealand to allow women to vote, and

3375-539: The governor. The main responsibility of this body was to draft a constitution for South Australia. The body drafted the most democratic constitution ever seen in the British Empire and provided for universal manhood suffrage . It created the bicameral Parliament of South Australia . For the first time in the colony, the executive was elected by the people, and the colony used the Westminster system , where

3450-585: The gradual development of the mineral resources of the district and its ultimate settlement.' The name of the Barrier Highway and various local organisations in Broken Hill including the word 'barrier', are derived from the name of this range. In 1844, during his third and final expedition, Charles Sturt named the range Stanley's Barrier Range in honour of Lord Stanley . South Australia South Australia (commonly abbreviated as SA )

3525-636: The inlet later named the Port Adelaide River which was first discovered in 1831 by Captain Collet Barker and later accurately charted in 1836–37 by Colonel William Light , leader of the South Australian Colonization Commissioners' 'First Expedition' and first Surveyor-General of South Australia. The land which now forms the state of South Australia was claimed for Britain in 1788 as part of

3600-445: The large stronghold of Framlingham Castle . Many different decorative effects have been achieved by using different types of knapping or arrangement and combinations with stone ( flushwork ), especially in the 15th and early 16th centuries. Because knapping flints to a relatively flush surface and size is a highly skilled process with a high level of wastage, flint finishes typically indicate high status buildings. During World War I, in

3675-403: The lead over other Australian states for its commercialisation and commitment to renewable energy . It is now the leading producer of wind power in Australia. Renewable energy is a growing source of electricity in South Australia, and there is potential for growth from this particular industry of the state's economy. The Hornsdale Power Reserve is a bank of grid-connected batteries adjacent to

3750-461: The least amount of federal funding for its local road network of all states on a per capita and a per kilometre basis. During 2019-20: South Australia's gross state product (GSP) fell 1.4% in chain volume (real) terms (nationally, gross domestic product (GDP) fell 0.3%). South Australia came out of the COVID-19 recession better than the other Australian states, with the economy growing by 3.9% in

3825-683: The letters patent of the imperial government to create the colony. He was accountable only to the British Colonial Office , and thus democracy did not exist in the colony. A new body was created to advise the governor on the administration of South Australia in 1843 called the Legislative Council. It consisted of three representatives of the British Government and four colonists appointed by the governor. The governor retained total executive power. In 1851,

3900-474: The material more homogeneous and thus more knappable and produces tools with a cleaner, sharper cutting edge. Heat treating was known to Stone Age artisans. When struck against steel, a flint edge produces sparks. The hard flint edge shaves off a particle of the steel that exposes iron, which reacts with oxygen from the atmosphere and can ignite the proper tinder . Prior to the wide availability of steel, rocks of pyrite (FeS 2 ) would be used along with

3975-493: The nation after Western Australia , with more than 77% of South Australians living in the capital Adelaide or its environs. Other population centres in the state are relatively small; Mount Gambier , the second-largest centre, has a population of 26,878. South Australia shares borders with all the other mainland states. It is bordered to the west by Western Australia , to the north by the Northern Territory , to

4050-676: The new province. 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

4125-628: The nodule, flint is usually dark grey or black, green, white, or brown in colour, and has a glassy or waxy appearance. A thin, oxidised layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along streams and beaches . Flint breaks and chips into sharp-edged pieces, making it useful in constructing a variety of cutting tools, such as knife blades and scrapers. The use of flint to make stone tools dates back more than three million years; flint's extreme durability has made it possible to accurately date its use over this time. Flint

4200-467: The north-east by Queensland , to the east by New South Wales , to 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

4275-534: 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

4350-481: 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

4425-635: The ridge. This "Ohio Flint" was traded across the eastern United States, and has been found as far west as the Rocky Mountains and south around the Gulf of Mexico . When struck against steel, flint will produce enough sparks to ignite a fire with the correct tinder , or gunpowder used in weapons , namely the flintlock firing mechanism . Although it has been superseded in these uses by different processes (the percussion cap ), or materials ( ferrocerium ), "flint" has lent its name as generic term for

4500-534: The south-eastern coast and River Murray . The state's colonial origins are unique in Australia as a freely settled, planned British province , rather than as a convict settlement. Colonial government commenced on 28 December 1836, when the members of the council were sworn in near the Old Gum Tree . As with the rest of the continent, the region has a long history of human occupation by numerous tribes and languages. The South Australian Company established

4575-547: 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

4725-424: The stone often reveal this effect. Flint sometimes occurs in large flint fields in Jurassic or Cretaceous beds, for example, in Europe. Puzzling giant flint formations known as paramoudra and flint circles are found around Europe but especially in Norfolk, England, on the beaches at Beeston Bump and West Runton . The "Ohio flint" is the official gemstone of Ohio state. It is formed from limey debris that

Flint, knapped or unknapped, has been used from antiquity (for example at the Late Roman fort of Burgh Castle in Norfolk) up to the present day as a material for building stone walls, using lime mortar, and often combined with other available stone or brick rubble. It

4875-423: 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

4950-487: The use of techniques like direct freehand percussion, freehand pressure and pressure using a rest. Other scholars who have conducted similar experiments and studies include William Henry Holmes , Alonzo W. Pond , Francis H. S. Knowles and Don Crabtree . To reduce susceptibility to fragmentation, flint/chert may be heat-treated, being slowly brought up to a temperature of 150 to 260 °C (300 to 500 °F) for 24 hours, then slowly cooled to room temperature. This makes

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

5100-440: Was deposited at the bottom of inland Paleozoic seas hundreds of millions of years ago that hardened into limestone and later became infused with silica . The flint from Flint Ridge is found in many hues like red, green, pink, blue, white, and grey, with the colour variations caused by minute impurities of iron compounds. Flint can be coloured: sandy brown, medium to dark grey, black, reddish brown or an off-white grey. Flint

5175-442: 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

It is especially associated with East Anglia , but also used in chalky areas stretching through Hampshire , Sussex, Surrey and Kent to Somerset . Flint was used in the construction of many churches, houses, and other buildings, for example,

5325-404: 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

5400-474: 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

5475-570: 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
