103-654: Iron Knob is a town in the Australian state of South Australia on the Eyre Peninsula immediately south of the Eyre Highway . At the 2006 census , Iron Knob and the surrounding area had a population of 199. The town obtained its name from its proximity to large deposits of iron ore , most notably Iron Monarch which outcropped prominently from the relatively flat, surrounding landscape. The name Iron Knob first appeared on pastoral lease maps of 1854. The first mineral claim in

206-479: A Mediterranean climate . The south-east ranges from oceanic (Tasmania and coastal Victoria) to humid subtropical (upper half of New South Wales), with the highlands featuring alpine and subpolar oceanic climates . The interior is arid to semi-arid . Driven by climate change , average temperatures have risen more than 1°C since 1960 . Associated changes in rainfall patterns and climate extremes exacerbate existing issues such as drought and bushfires . 2019

309-511: A belt of Brigalow grasslands lie between the coast and the mountains, while inland of the dividing range are large areas of grassland and shrubland. These include the western plains of New South Wales, and the Mitchell Grass Downs and Mulga Lands of inland Queensland. The northernmost point of the mainland is the tropical Cape York Peninsula . The landscapes of the Top End and

412-793: A large wave of immigration from across Europe , with such immigrants referred to as " New Australians ". This required a relaxation of the white Australia policy , which was justified to Australians using the slogan "populate or perish". A member of the Western Bloc during the Cold War , Australia participated in the Korean War and the Malayan Emergency during the 1950s and the Vietnam War from 1962 to 1972. During this time, tensions over communist influence in society led to unsuccessful attempts by

515-461: A date which later became Australia's national day . Most early settlers were convicts , transported for petty crimes and assigned as labourers or servants to "free settlers" (willing immigrants). Once emancipated , convicts tended to integrate into colonial society. Convict rebellions and uprisings were suppressed under martial law, which lasted for two years following the 1808 Rum Rebellion , Australia's only successful coup d'état . During

618-597: A good week. Construction of a private railway greatly increased transportation rates and by 1939, 9000 long tons (10,080 short tons) of ore were delivered daily to Whyalla by rail; trains carried loads of 2000 long tons (2240 short tons). Ships operated by the BHP Shipping were named with Iron as their prefix; some were built by the company at the Whyalla Steelworks . Highway 1 regularly closes due to controlled explosions. Australia Australia , officially

721-568: A settlement was established in Van Diemen's Land (present-day Tasmania ), and in 1813, Gregory Blaxland , William Lawson and William Wentworth crossed the Blue Mountains west of Sydney, opening the interior to European settlement. The British claim extended to the whole Australian continent in 1827 when Major Edmund Lockyer established a settlement on King George Sound (modern-day Albany ). The Swan River Colony (present-day Perth )

824-548: A short distance off the north-east coast and extends for more than 2,000 km (1,200 mi). Mount Augustus , claimed to be the world's largest monolith, is located in Western Australia. At 2,228 m (7,310 ft), Mount Kosciuszko is the highest mountain on the Australian mainland. Even taller are Mawson Peak , at 2,745 m (9,006 ft), on the remote Australian external territory of Heard Island , and, in

927-411: A wide variety of landscapes, with tropical rainforests in the north-east, mountain ranges in the south-east, south-west and east, and desert in the centre. The desert or semi-arid land commonly known as the outback makes up by far the largest portion of land. Australia is the driest inhabited continent; its annual rainfall averaged over continental area is less than 500 mm. The population density

1030-436: Is 3.4 inhabitants per square kilometre, although the large majority of the population lives along the temperate south-eastern coastline. The population density exceeds 19,500 inhabitants per square kilometre in central Melbourne. In 2021 Australia had 10% of the global permanent meadows and pastureland. Forest cover is around 17% of Australia's total land area. The Great Barrier Reef , the world's largest coral reef, lies

1133-413: Is a constitutional monarchy , a parliamentary democracy and a federation . The country has maintained its mostly unchanged constitution alongside a stable liberal democratic political system since Federation in 1901. It is one of the world's oldest federations, in which power is divided between the federal and state governments. The Australian system of government combines elements derived from

Whyalla Steelworks The Whyalla Steelworks is a fully integrated steelworks and the only manufacturer of rail in Australia. Iron ore is mined in the Middleback Range to feed the steelworks, resulting in

1339-517: Is now Southeast Asia. It is uncertain how many waves of immigration may have contributed to these ancestors of modern Aboriginal Australians. The Madjedbebe rock shelter in Arnhem Land is possibly the oldest site showing the presence of humans in Australia. The oldest human remains found are the Lake Mungo remains , which have been dated to around 41,000 years ago. Aboriginal Australian culture

1442-557: Is one of only two pristine Archaean 3.6–2.7 Ga (billion years ago) crusts identified on the Earth. Having been part of all major supercontinents , the Australian continent began to form after the breakup of Gondwana in the Permian , with the separation of the continental landmass from the African continent and Indian subcontinent. It separated from Antarctica over a prolonged period beginning in

1545-460: Is one of the oldest continuous cultures on Earth. At the time of first European contact, Aboriginal Australians belonged to wide range of societies, with diverse economies spread across at least 250 different language groups . Estimates of the Aboriginal population before British settlement range from 300,000 to 3 million. Aboriginal Australians cultures were (and remain) deeply connected with

1648-411: Is unique. About 85% of flowering plants, 84% of mammals, more than 45% of birds , and 89% of in-shore, temperate-zone fish are endemic . Australia has at least 755 species of reptile, more than any other country in the world. Besides Antarctica, Australia is the only continent that developed without feline species. Feral cats may have been introduced in the 17th century by Dutch shipwrecks, and later in

1751-459: The BOS for manufacture into steel. Coke is produced on site from coal supplied to the plant from Newcastle or Port Kembla and ships are loaded with iron ore for shipment from Whyalla's port. Finished steel products are distributed by sea, road and rail. In 2020, the slip at the former shipyard was recommissioned as a facility to decommission, scrap and recycle (DSR) large ships. It was reported to be

1854-731: The Colonial Office that it be formally adopted. In 1824, the Admiralty agreed that the continent should be known officially by that name. The first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office . Colloquial names for Australia include " Oz ", " Straya " and " Down Under ". Other epithets include "the Great Southern Land", "the Lucky Country" (from

1957-524: The Commonwealth of Australia , is a country comprising the mainland of the Australian continent , the island of Tasmania and numerous smaller islands . Australia has a total area of 7,688,287 km (2,968,464 sq mi), making it the sixth-largest country in the world and the largest country by area in Oceania . It is the world's oldest, flattest, and driest inhabited continent, with some of

2266-529: The Iraq War from 2003 to 2009. The nation's trade relations also became increasingly oriented towards East Asia in the 21st century, with China becoming the nation's largest trading partner by a large margin. In 2020, during the COVID-19 pandemic , several of Australia's largest cities were locked down for extended periods and free movement across the national and state borders was restricted in an attempt to slow

2369-638: The Menzies Government to ban the Communist Party of Australia , and a bitter split in the Labor Party in 1955. As a result of a 1967 referendum , the federal government gained the power to legislate with regard to Indigenous Australians, and Indigenous Australians were fully included in the census . Pre-colonial land interests (referred to as native title in Australia) was recognised in law for

2472-701: The Pacific Community ; the Commonwealth of Nations ; and the defence and security organisations ANZUS , AUKUS , and the Five Eyes . It is also a major non-NATO ally of the United States. The name Australia (pronounced / ə ˈ s t r eɪ l i ə / in Australian English ) is derived from the Latin Terra Australis ( ' southern land ' ), a name used for a hypothetical continent in

2575-520: The Permian and continuing through to the Cretaceous . When the last glacial period ended in about 10,000 BC, rising sea levels formed Bass Strait , separating Tasmania from the mainland. Then between about 8,000 and 6,500 BC, the lowlands in the north were flooded by the sea, separating New Guinea, the Aru Islands , and the mainland of Australia. The Australian continent is moving toward Eurasia at

2678-663: The Territory of Papua and New Guinea in 1949 and gained independence from Australia in 1975. In 1914, Australia joined the Allies in fighting the First World War, and took part in many of the major battles fought on the Western Front . Of about 416,000 who served, about 60,000 were killed and another 152,000 were wounded. Many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZAC) at Gallipoli in 1915 as

2781-514: The Torres Strait Islands . The Dutch charted the whole of the western and northern coastlines and named the island continent " New Holland " during the 17th century, and although no attempt at settlement was made, a number of shipwrecks left men either stranded or, as in the case of the Batavia in 1629, marooned for mutiny and murder, thus becoming the first Europeans to permanently inhabit

2884-678: The bombing of Darwin and other Japanese attacks on Australian soil , led to a widespread belief in Australia that a Japanese invasion was imminent , and a shift from the United Kingdom to the United States as Australia's principal ally and security partner. Since 1951, Australia has been allied with the United States under the ANZUS treaty. In the decades following World War II, Australia enjoyed significant increases in living standards, leisure time and suburban development. Governments encouraged

2987-426: The emu and the kookaburra . Australia is home to many dangerous animals including some of the most venomous snakes in the world. The dingo was introduced by Austronesian people who traded with Indigenous Australians around 3000 BCE . Many animal and plant species became extinct soon after first human settlement, including the Australian megafauna ; others have disappeared since European settlement, among them

3090-584: The governor-general at the federal level and by the governors at the state level, who by section 63 of the Constitution and convention act on the advice of their ministers. Thus, in practice the governor-general acts as a legal figurehead for the actions of the prime minister and the Cabinet. The governor-general may in some situations exercise reserve powers : powers exercisable in the absence or contrary to ministerial advice. When these powers may be exercised

3193-643: The "baptism of fire" that forged the new nation's identity . The beginning of the campaign is commemorated annually on Anzac Day , a date which rivals Australia Day as the nation's most important. From 1939 to 1945, Australia joined the Allies in fighting the Second World War. Australia's armed forces fought in the Pacific , European and Mediterranean and Middle East theatres .

3296-575: The "island continent" and is sometimes considered the world's largest island . Australia has 34,218 km (21,262 mi) of coastline (excluding all offshore islands), and claims an extensive exclusive economic zone of 8,148,250 square kilometres (3,146,060 sq mi). This exclusive economic zone does not include the Australian Antarctic Territory . Mainland Australia lies between latitudes 9° and 44° south , and longitudes 112° and 154° east . Australia's size gives it

3399-428: The 18th century by European settlers. They are now considered a major factor in the decline and extinction of many vulnerable and endangered native species. Seafaring immigrants from Asia are believed to have brought the dingo to Australia sometime after the end of the last ice age—perhaps 4000 years ago—and Aboriginal people helped disperse them across the continent as pets, contributing to the demise of thylacines on

3502-524: The 1964 book of the same name ), "the Sunburnt Country", and "the Wide Brown Land". The latter two both derive from Dorothea Mackellar 's 1908 poem " My Country ". Indigenous Australians comprise two broad groups: Human habitation of the Australian continent is estimated to have begun 50,000 to 65,000 years ago, with the migration of people by land bridges and short sea crossings from what

3605-529: The 2018 Environmental Performance Index . There are more than 1,800 animals and plants on Australia's threatened species list, including more than 500 animals. Paleontologists discovered a fossil site of a prehistoric rainforest in McGraths Flat , in South Australia, that presents evidence that this now arid desert and dry shrubland / grassland was once home to an abundance of life. Australia

3708-635: The Australian Antarctic Territory, Mount McClintock and Mount Menzies , at 3,492 m (11,457 ft) and 3,355 m (11,007 ft) respectively. Eastern Australia is marked by the Great Dividing Range , which runs parallel to the coast of Queensland, New South Wales and much of Victoria. The name is not strictly accurate, because parts of the range consist of low hills, and the highlands are typically no more than 1,600 m (5,200 ft) in height. The coastal uplands and

3811-545: The Australian mainland. The first ship and crew to chart the Australian coast and meet with Aboriginal people was the Duyfken , captained by Dutch navigator Willem Janszoon . He sighted the coast of Cape York Peninsula in early 1606, and made landfall on 26 February 1606 at the Pennefather River near the modern town of Weipa on Cape York. Later that year, Spanish explorer Luís Vaz de Torres sailed through and navigated

3914-593: The Commonwealth of Australia. This continued a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942 , and culminating in the Australia Acts of 1986. Australia is a federal parliamentary democracy and constitutional monarchy comprising six states and ten territories . Its population of more than 28 million is highly urbanised and heavily concentrated on

4017-454: The Iron Monarch mine. The Iron Monarch mine was prepared for reopening by Arrium in 2013. As of 2015, both Iron Monarch and Iron Duke continue to produce iron ore for export and for smelting at the Whyalla Steelworks . In the early days of mining at Iron Knob, ironstone was carted by oxen to Hummock Hill (renamed Whyalla in 1914). Approximately 300 long tons (336 short tons) was delivered in

4120-696: The Southern Hemisphere since ancient times. Several 16th-century cartographers used the word Australia on maps, but not to identify modern Australia. When Europeans began visiting and mapping Australia in the 17th century, the name Terra Australis was applied to the new territories. Until the early 19th century, Australia was best known as New Holland , a name first applied by the Dutch explorer Abel Tasman in 1644 (as Nieuw-Holland ) and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts. The name Australia

4326-800: The Whyalla Visitors Centre. The Whyalla Steelworks receives iron ore mined at various sites along the Middleback Range . Iron ore mining in this region dates back to at least 1900. Prior to the steelworks' construction, the ore was shipped from Whyalla (then known as Hummock Hill) to Port Pirie for use as a flux in smelters. It was later supplied to steel-making facilities at Port Kembla, New South Wales . The first shipment of iron ore by sea for Port Pirie departed Whyalla in 1903. The first mines to be developed were Iron Knob and Iron Monarch, with later developments including Iron Baron , Iron Knight, Iron Princess, Iron Chieftain and Iron Duke. The mines were developed by BHP , which went on to develop

4429-603: The Whyalla shipyards. In 1947, Australia's largest domestically built vessel, the bulk carrier Iron Yampi , was launched. It was built for BHP Shipping to transport iron ore from Yampi Sound in Western Australia. In 1965, the honor was claimed again, when the Darling River was launched. With the launch of the tanker Arthur Phillip in 1974, the Whyalla shipyard passed a major milestone, having produced over one million tonnes of merchant vessels in total. The shipyard also produced

4532-483: The Whyalla steelworks have been considered as a potential cause of elevated lung cancer incidence among residents of Whyalla. Between 1999 and 2004, 95 cases of lung cancer were recorded - 32 more than the Government of South Australia 's Department of Health anticipated based on studies of other regions in the state. Concerns regarding emissions and their health impacts came to a head between 2005 and 2007, largely due to

4635-517: The area was pegged by BHP in 1897. Mining commenced in 1900. Iron ore was first transported by bullock wagon to Port Augusta , where it was loaded on to 200-ton barges. From 1903, it was transported by rail to Whyalla and ship to Port Pirie where it was used as a flux in the lead smelter there. In 1901 the BHP Whyalla Tramway from Iron Knob to Hummock Hill (later renamed Whyalla ) was completed, followed by wharves in 1903. These allowed

4738-610: The centre and Phanerozoic sedimentary basins , metamorphic and igneous rocks in the east. The Australian mainland and Tasmania are situated in the middle of the tectonic plate and have no active volcanoes, but due to passing over the East Australia hotspot , recent volcanism has occurred during the Holocene , in the Newer Volcanics Province of western Victoria and south-eastern South Australia. Volcanism also occurs in

4841-477: The colonies was achieved after a decade of planning, constitutional conventions and referendums , resulting in the establishment of the Commonwealth of Australia as a nation under the new Australian Constitution . After the 1907 Imperial Conference , Australia and several other self-governing British settler colonies were given the status of self-governing dominions within the British Empire. Australia

4944-609: The company's emissions was now left in the hands of the Minister for Mineral Resources. At the time, Premier Mike Rann was critical of the EPA, describing it as a 'toothless tiger... because it didn't have the backing of government, it didn't have independence'. As public and political pressure persisted, the Government eventually modified the licensing conditions for the facility's allowable airborne pollution emissions. This included reducing

5047-807: The continent. In 1770, Captain James Cook sailed along and mapped the east coast, which he named " New South Wales " and claimed for Great Britain. Following the loss of its American colonies in 1783, the British Government sent a fleet of ships, the First Fleet , under the command of Captain Arthur Phillip , to establish a new penal colony in New South Wales . A camp was set up and the Union Flag raised at Sydney Cove , Port Jackson , on 26 January 1788,

5150-583: The convict system culminated in its abolition in the eastern colonies by the 1850s. Initially a free colony, Western Australia practised penal transportation from 1850 to 1868. The six colonies individually gained responsible government between 1855 and 1890, thus becoming elective democracies managing most of their own affairs while remaining part of the British Empire . The Colonial Office in London retained control of some matters, notably foreign affairs. In

5253-425: The country's economy. It ranks highly for quality of life, health, education, economic freedom, civil liberties and political rights. Australia is a middle power , and has the world's thirteenth-highest military expenditure . It is a member of international groups including the United Nations; the G20 ; the OECD ; the World Trade Organization ; Asia-Pacific Economic Cooperation ; the Pacific Islands Forum ;

5356-432: The direct loading of ships which could transport the ore across Spencer Gulf to Port Pirie. Iron Knob's iron ore proved to be of such high quality (upwards of 60% purity) that it led to the development of the Australian steel industry. It supplied iron to the Newcastle Steelworks and Port Kembla in the 1910s and 1920s and Whyalla in the 1930s. The iron ore was transported by the BHP Whyalla Tramway to Whyalla where it

5459-414: The distribution of finished steel products of over 90 different grades. It occupies a 1,000 ha site on the shore of False Bay , Spencer Gulf and is the largest employer in Whyalla , South Australia . Approximately 1.2 million tonnes of raw steel is produced in the steelworks each year, with about 65% of that transferred by rail to Arrium 's Market Mills as billets for further processing. The balance of

5562-459: The early 2010s after the 2000s Australian drought . Although most of Australia is semi-arid or desert, the continent includes a diverse range of habitats from alpine heaths to tropical rainforests . Fungi typify that diversity—an estimated 250,000 species—of which only 5% have been described—occur in Australia. Because of the continent's great age, extremely variable weather patterns, and long-term geographic isolation, much of Australia's biota

5665-481: The eastern seaboard. Canberra is the nation's capital, while its most populous cities are Sydney and Melbourne , both with a population of more than 5 million. Australia's culture is diverse, and the country has one of the highest foreign-born populations in the world . It has a highly developed market economy and one of the highest per capita incomes globally . Its abundant natural resources and well-developed international trade relations are crucial to

5768-449: The efforts of Ted Kittel and the community-lead Whyalla Red Dust Action Group. Residents of East Whyalla and students of the Whyalla Town Primary School are believed to be worst impacted by the dust emissions due to their proximity to the source. The public controversy was predicated by a legal case heard in the Environment, Resources and Development Court in 2005, EPA v. OneSteel. The case evaporated after OneSteel successfully renegotiated

5871-413: The export of iron ore to Japan, leading to strikes and arrests. In 1937, output from the Middleback Range , mostly from Iron Monarch was estimated at 2 mtpa. In 1939, it was referred to in England as the highest grade deposit of iron ore known in the world. In 1943, the iron Knob deposit was still delivering an average ore grade of 64 percent metallic content. In 1949, 99% of Australian demand for iron ore

5974-477: The first blast furnace 'blown in'. A shipyard was also constructed, designed to aid the British Commonwealth 's efforts in World War II . After the war, the steelworks and shipyards continued to produce a range of products including rail track and maritime vessels for commercial use. In the 1960s, a BOS rolling mills and coke ovens were constructed, enabling the Whyalla plant to become a fully integrated steelworks. Various records were set and milestones met by

6077-601: The first time when the High Court of Australia held in Mabo v Queensland (No 2) that Australia was neither terra nullius ( ' land belonging to no one ' ) or "desert and uncultivated land" at the time of European settlement. Following the abolition of the last vestiges of the White Australia policy in 1973, Australia's demography and culture transformed as a result of a large and ongoing wave of non-European immigration, mostly from Asia. The late 20th century also saw an increasing focus on foreign policy ties with other Pacific Rim nations. The Australia Acts severed

6180-422: The government for initially relaxing the EPA licensing conditions on dust emissions by modifying the company's Indenture Act after significant breaches were recorded in 2005. The Australian Democrats ' leader Sandra Kanck was critical of the removal of the Minister for the Environment from the role of overseeing emissions licensing for OneSteel. The party was concerned that the sole ministerial responsibility for

6283-412: The heart of the country are the uplands of central Australia . Prominent features of the centre and south include Uluru (also known as Ayers Rock), the famous sandstone monolith, and the inland Simpson , Tirari and Sturt Stony , Gibson , Great Sandy, Tanami , and Great Victoria deserts, with the famous Nullarbor Plain on the southern coast. The Western Australian mulga shrublands lie between

Lying on the Indo-Australian Plate , the mainland of Australia is the lowest and most primordial landmass on Earth with a relatively stable geological history. The landmass includes virtually all known rock types and from all geological time periods spanning more than 3.8 billion years of the Earth's history. The Pilbara Craton

6489-417: The island of New Guinea (considered geologically as part of the Australian continent), and in the Australian external territory of Heard Island and McDonald Islands . Seismic activity in the Australian mainland and Tasmania is also low, with the greatest number of fatalities having occurred in the 1989 Newcastle earthquake . The climate of Australia is significantly influenced by ocean currents, including

6592-620: The land and the environment, with stories of The Dreaming maintained through oral tradition , songs , dance and paintings. Certain groups engaged in fire-stick farming , fish farming , and built semi-permanent shelters . These practices have variously been characterised as " hunter-gatherer ", " agricultural ", "natural cultivation" and "intensification". Torres Strait Islander people first settled their islands at least 2,500 years ago. Culturally and linguistically distinct from mainland Aboriginal peoples, they were seafarers and obtained their livelihood from seasonal horticulture and

6695-447: The least fertile soils. It is a megadiverse country , and its size gives it a wide variety of landscapes and climates including deserts in the interior and tropical rainforests along the coast . The ancestors of Aboriginal Australians began arriving from south-east Asia 50,000 to 65,000 years ago, during the last glacial period . By the time of British settlement, Aboriginal Australians spoke 250 distinct languages and had

6798-494: The location for the future federal capital of Canberra . While it was being constructed, Melbourne served as the temporary capital from 1901 to 1927. The Northern Territory was transferred from the control of South Australia to the Commonwealth in 1911. Australia became the colonial ruler of the Territory of Papua (which had initially been annexed by Queensland in 1883) in 1902 and of the Territory of New Guinea (formerly German New Guinea ) in 1920. The two were unified as

6901-448: The mainland. Australia is also one of 17 megadiverse countries. Australian forests are mostly made up of evergreen species, particularly eucalyptus trees in the less arid regions; wattles replace them as the dominant species in drier regions and deserts. Among well-known Australian animals are the monotremes (the platypus and echidna ); a host of marsupials , including the kangaroo , koala , and wombat , and birds such as

7004-408: The mid-19th century, explorers such as Burke and Wills charted Australia's interior. A series of gold rushes beginning in the early 1850s led to an influx of new migrants from China , North America and continental Europe, as well as outbreaks of bushranging and civil unrest; the latter peaked in 1854 when Ballarat miners launched the Eureka Rebellion against gold license fees. The 1860s saw

7107-602: The next two decades, social and economic reforms, together with the establishment of a Legislative Council and Supreme Court , saw the penal colony transition to a civil society. The indigenous population declined for 150 years following European settlement, mainly due to infectious disease. British colonial authorities did not sign any treaties with Aboriginal groups . As settlement expanded, tens of thousands of Indigenous people and thousands of settlers were killed in frontier conflicts while settlers dispossessed surviving Indigenous peoples of most of their land. In 1803,

7210-578: The number of days per year that excessive dust was permitted. In 2006, 29 days of 'excessive dust' were recorded. The changed conditions would limit breaches to 10 days in 2008, and ultimately 5 days in 2011. Additional breaches could incur a fine of up to $ 120,000. The company was required to report monthly to the Government of South Australia with emissions reports and details of any remedial actions taken. Despite describing their 'journey' with Whyalla's dust-affected community as 'reactive', 'very closed door', and 'adversarial', OneSteel eventually worked with

7313-498: The oldest living culture in the world. Australia's written history commenced with Dutch exploration of most of the coastline in the 17th-century. British colonisation began in 1788 with the establishment of the penal colony of New South Wales . By the mid-19th century, most of the continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming

7416-554: The only facility in Australia capable of handling ships over 200 m (660 ft). The first ship through the facility was the former HMAS  Success . The initial deconstruction work was done by McMahon Services at Port Pirie before the hull was moved across Spencer Gulf to Whyalla. As of 2021, the interests of the works' owners, GFG Alliance, are represented to the South Australian parliament by lobbying firm, Bespoke Approach. The Broken Hill Proprietary Company (BHP)

7519-583: The plan. Once it is up and running, it will supply power to the steelworks, which will then produce green steel . The Whyalla Steelworks draws the majority of its required water from the Murray River , via the Morgan-Whyalla pipeline. In December 2011, a reverse osmosis seawater desalination plant was commissioned. Capable of producing 1.5 GL of water per year, the plant allows Arrium to reduce Murray River water consumption by up to 25%. The brine from

7622-408: The plant is discharged into settling ponds which flow into the waters of False Bay , Spencer Gulf . A rail network exists within the steelworks. Built as a narrow gauge network, it was converted to standard gauge in the 1960s. In 1901, a line opened from Whyalla to Iron Knob. In 1930, a branch opened from Middleton Junction to Iron Baron. The latter closed in 1947 being reopened in 1958. In 1990, it

7725-544: The plant. Two 4.2 MW gas turbines operate exclusively on purchased natural gas . Despite this on-site capacity, the plant relies on purchased electricity for a substantial portion of its needs, and only exports power to the grid occasionally. Plans for the associated 280 MW Cultana Solar Farm were abandoned in 2021. Santos has supplied gas to the steelworks for several years, and in February 2025 signed an MoU with GFG Alliance to start discussions to reduce emissions from

7828-428: The political systems of the United Kingdom (a fused executive , constitutional monarchy and strong party discipline ) and the United States ( federalism , a written constitution and strong bicameralism with an elected upper house), resulting in a distinct hybrid. Federal government power is partially separated between three groups: Charles III reigns as King of Australia and is represented in Australia by

7931-483: The project's economic merits. The project represented a $ 395 million investment in the development of Whyalla's economy with coincidental environmental benefits. The plan was to be implemented by 2008. The company also engages in the assessment and remediation of buildings in the town of Whyalla, with results and other emissions statistics published in The Whyalla News . Greens MLC Mark Parnell openly criticised

8034-572: The protection of threatened species. Numerous protected areas have been created under the National Strategy for the Conservation of Australia's Biological Diversity to protect and preserve unique ecosystems; 65 wetlands are listed under the Ramsar Convention , and 16 natural World Heritage Sites have been established. Australia was ranked 21st out of 178 countries in the world on

8137-445: The quarrying stopped, the town population declined to 200 and Iron Knob was under threat of becoming a ghost town . However, due to rising prices of housing elsewhere, the town has attracted new residents seeking low cost residences. A home could be purchased for approximately A$ 35,000–70,000 and vacant land could be purchased for less than A$ 15,000. In 2010, Onesteel (later Arrium ) announced that it would return to Iron Knob to reopen

8240-475: The rate of 6 to 7 centimetres a year. The Australian mainland's continental crust , excluding the thinned margins, has an average thickness of 38   km, with a range in thickness from 24 km to 59 km. Australia's geology can be divided into several main sections, showcasing that the continent grew from west to east: the Archaean cratonic shields found mostly in the west, Proterozoic fold belts in

8343-533: The remaining constitutional ties between Australia and the United Kingdom while maintaining the monarch in her independent capacity as Queen of Australia . In a 1999 constitutional referendum , 55% of voters rejected abolishing the monarchy and becoming a republic. Following the September 11 attacks on the United States, Australia joined the United States in fighting the Afghanistan War from 2001 to 2021 and

8446-419: The resources of their reefs and seas. Agriculture also developed on some islands and villages appeared by the 1300s. By the mid-18th century in northern Australia, contact, trade and cross-cultural engagement had been established between local Aboriginal groups and Makassan trepangers , visiting from present-day Indonesia. The Dutch are the first Europeans that recorded sighting and making landfall on

8549-491: The rise of blackbirding , where South Sea Islanders were coerced or abducted into indentured labour, mainly by Queensland colonists. From 1886, Australian colonial governments began removing many Aboriginal children from their families and communities, justified on the grounds of child protection and forced assimilation policies. The Second Boer War (1899–1902) marked the largest overseas deployment of Australia's colonial forces . On 1 January 1901, federation of

8652-709: The spread of the SARS-CoV-2 virus . Surrounded by the Indian and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas, with the Coral Sea lying off the Queensland coast, and the Tasman Sea lying between Australia and New Zealand. The world's smallest continent and sixth-largest country by total area , Australia—owing to its size and isolation—is often dubbed

8755-586: The steel is then converted to finished products at the Whyalla Rolling Mill. These products service the construction and rail transport industries. Dust emissions from the steelworks became a controversial topic in 2005 after legislation was rewritten to nullify a legal battle between OneSteel and the South Australian Environmental Protection Agency. The steelworks is open to the public for guided tours which can be booked at

8858-513: The steelworks and shipyards. The steelworks first established a plant for the production of pig-iron for sale or use at other BHP plants. The announcement was made in 1937 and South Australian legislation was prepared to facilitate the development. Water security for the project was also guaranteed by the development of the Morgan-Whyalla pipeline . The Whyalla Steelworks was opened in May 1941 with

8961-472: The steelworks employed 1,600 people, down from a peak of around 6,000. The steelworks is owned by Liberty House Group , who purchased Arrium in September 2017. Arrium was previously known as OneSteel, and was spun off from BHP in 2000. The iron-making department incorporates the blast furnace, coke ovens and the power and services departments of the Whyalla steelworks. Molten iron is supplied from here to

9064-509: The steelworks. The Whyalla Hydrogen Facility is a proposed 250MWe hydrogen electrolyser, a 200MW combined cycle gas turbine generator, and 3600-tonne hydrogen storage facility, which will supply electricity to the steelworks using green hydrogen . A South Australian Government company called Hydrogen Power South Australia was established to own and operate the plant, which is expected to be completed in 2025 and begin operations in 2026. ATCO Australia , BOC , and Epic Energy will deliver

9167-517: The terms of their governing Indenture Act, with the support of the Government of South Australia. OneSteel responded by incorporating new processes into the design of Project Magnet . By proposing to transport ore from the Iron Duke mine in a slurry pipeline, the company hoped to reduce opportunities for the emission of excessive red dust. The project was supported by acting Premier Kevin Foley who espoused

9270-406: The thylacine. Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced animal, chromistan , fungal and plant species. All these factors have led to Australia's having the highest mammal extinction rate of any country in the world. The federal Environment Protection and Biodiversity Conservation Act 1999 is the legal framework for

9373-449: The visual appearance of dust-impacted areas in Whyalla. The WRDAG was disbanded in 2010 after agreement that the red dust issue had been addressed. Former chair of the WRDAG, Ted Kittel, stated “The problem is resolved with a fair and reasonable outcome. I believe that OneSteel has now set a benchmark in the way it addresses environmental issues and in the excellent way it now communicates with

9476-475: The world's first gas turbine-electric powered ship, the Seaway Prince in 1975. BHP 's shipyards continued to operate until 1978. Many of the vessels were produced for the use of BHP Shipping . The eventual closure of the shipyards came as a major blow to the town of Whyalla and plunged it into an economic recession , with 1,800 workers made redundant. In 1982, the steelworks employed 5,000 people. In 2011,

9579-615: Was Australia's warmest recorded year, and the 2019–2020 bushfire season was the country's worst on record . Australia's greenhouse gas emissions per capita are among the highest in the world. Water restrictions are frequently in place in many regions and cities of Australia in response to chronic shortages due to urban population increases and localised drought. Throughout much of the continent, major flooding regularly follows extended periods of drought, flushing out inland river systems, overflowing dams and inundating large inland flood plains, as occurred throughout Eastern Australia in

9682-460: Was also exported to Japan . In the financial year 1935–36, 291,961 tonnes of ore from Iron Knob was shipped there via the seaport of Whyalla. This became a controversial matter in the late 1930s due in part to Australia's known reserves at the time being limited to Iron Knob and Yampi Sound in Western Australia. Japan was also considered an 'aggressor' nation following acts of war against China in 1937. Waterfront workers and seamen protested against

9785-640: Was either smelted or dispatched by sea. 21% of the steel required for the construction of the Sydney Harbour Bridge was quarried at Iron Knob and smelted at Port Kembla , New South Wales. The remaining 79% was imported from Britain. In the 1920s, iron ore from Iron Knob was exported to the Netherlands and the United States of America . In the 1930s, customers included Germany and the United Kingdom . Prior to World War II, iron ore from Iron Knob

9888-413: Was established in 1829, evolving into the largest Australian colony by area, Western Australia . In accordance with population growth, separate colonies were carved from New South Wales: Tasmania in 1825, South Australia in 1836, New Zealand in 1841, Victoria in 1851, and Queensland in 1859. South Australia was founded as a free colony—it never accepted transported convicts. Growing opposition to

9991-518: Was extended 40 kilometres from Iron Baron to Iron Duke. After iron ore production ceased at Iron Baron in 1991 and Iron Duke in 1998, the line from Middleton Junction closed. With the reopening of the Iron Baron Mine in mid-2012, the line reopened to Iron Baron. In October 1972, the 74 kilometre Whyalla railway line opened primarily to serve the Whyalla Steelworks. Dust emissions from

10094-928: Was extended to Whyalla by the late 1950s. While the town's supply was progressively transferred to ETSA during the 1960s, BHP continued to supply much of its own needs and those of some other customers that were not economic to transfer to the ETSA network. As BHP's power needs grew it began to use grid power for a greater portion of its own needs. However, as of 2016 the steelworks continues to generate its own electricity to lower its energy costs and increase security of supply. In 2005, Whyalla Steelworks had 66.5 MW of dedicated electricity generating capacity on-site. 57.5 MW of this capacity consisted of three turbo alternators driven by steam raised in various boilers, fired primarily by waste blast furnace and coke oven gases. The boilers can also be fired with supplementary fuel oil and natural gas. The boilers also provide steam for process use around

10197-582: Was met by supply from Iron Knob and associated mines in South Australia, having risen from 95% in 1943. Additional deposits of iron ore were developed by the Broken Hill Proprietary Company further south along the Middleback Range. These include Iron Baron, Iron Prince and Iron Queen (discovered in 1920) and Iron Knight, Iron Duchess and Iron Duke (discovered in 1934). Quarrying for iron at Iron Knob and Iron Monarch ended in 1998. When

10300-565: Was one of the founding members of the League of Nations in 1920, and the United Nations in 1945. The Statute of Westminster 1931 formally ended the ability of the UK to pass federal laws without Australia's consent. Australia adopted it in 1942, but it was backdated to 1939 to confirm the validity of legislation passed during World War II. The Australian Capital Territory was formed in 1911 as

10403-466: Was popularised by the explorer Matthew Flinders , who said it was "more agreeable to the ear, and an assimilation to the names of the other great portions of the Earth". The first time that Australia appears to have been officially used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst . In December 1817, Macquarie recommended to

10506-437: Was responsible for bringing electricity to the townships of Iron Knob, Whyalla, their associated mines and ultimately the Whyalla steelworks. This was achieved by the construction of three powerhouses and network infrastructure to reticulate the power. BHP commenced power supply to Whyalla in 1908 and Iron Knob in 1922. A second powerhouse was built in the 1920s to replace the first and was decommissioned in late 1941 (though it

10609-491: Was still standing in the 1990s). The third powerhouse was built in 1941 as part of the No.1 Blast furnace. It features two turbo alternators and two turbo blowers and remains in operation. It provides electricity for use around the plant and air to the blast furnace. Compressed air is also utilised around the plant by a number of other departments. The South Australian grid, run by the then Electricity Trust of South Australia (ETSA),
