==History== ===Geological=== [[File:Wolfe creek meteorite crater.jpg|thumb|Wolfe Creek Crater in Western Australia]] The area's geology spans a geological time period of over 3.8 billion years, therefore featuring some of the oldest rocks on earth. There are three main cratonic shields of recognised Archaean age within the Australian landmass: The Yilgarn, the Pilbara and the Gawler cratons. Several other Archaean-Proterozoic orogenic belts exist, usually sandwiched around the edges of these major cratonic shields. The history of the Archaean cratons is extremely complex and protracted. The cratons appear to have been accumulated to form the greater Australian landmass in the late Archaean to meso-Proterozoic, (~2400 Ma to 1,600 Ma).
Chiefly the Capricorn Orogeny is partly responsible for the assembly of the West Australian landmass by connecting the Yilgarn and Pilbara cratons. The Capricorn Orogeny is exposed in the rocks of the Bangemall Basin, Gascoyne Complex granite-gneisses and the Glengarry, Yerrida and Padbury basins. Unknown Proterozoic orogenic belts, possibly similar to the Albany Complex in southern Western Australia and the Musgrave Block, represent the Proterozoic link between the Yilgarn and Gawler cratons, covered by the Proterozoic-Palaeozoic Officer and Amadeus basins.<ref>Pirajno, F., Occhipinti, S.

Aboriginal tribes and clans have been nomadic in the desert areas for thousands of years. They subsisted on the local flora and fauna, now known as bush food, and made sure that their sources of drinking water remained intact. The nomads moved in clearly demarcated tribal areas. For example, important tribes living in the desert areas include the Arrernte, Luritja and Pitjantjatjara. The latter tribe's sphere of influence extended from Uluṟu to the Nullarbor Plain. The Dieri tribe lives in a large area of the Simpson, Strzelecki and Tirari deserts.<ref>{{Cite book| title = Notes on the Dieri tribe of South Australia | last1 = Berndt | first1 = Ronald Murray | last2 = Vogelsang | first2 = T. | author1-link = Ronald Berndt | year = 1939 | publisher = Royal Society of South Australia }}</ref>

The isolated desert areas remained undeveloped for a long time. For example, the Spinifex people first had contact with whites in the 1950s, when they were expelled from their tribal lands because of nuclear weapons testing (1950–1963) by the British and Australian governments. The Pintupi Nine, a group of nine Aboriginal people of the Pintupi tribe, lived a nomadic hunter-gatherer lifestyle in the Gibson Desert until October 1984, when they first encountered whites as they left the desert.

There are four known types of terrestrial deserts:
* continental (or remote) deserts * tropical (or zonal) deserts * shelter deserts * coastal deserts Australian deserts generally meet the first three criteria, although some coastal desert areas exist in Western Australia. The great ocean circulation in the south of the continent and the cold sea currents in the southern zone play the fourth crucial role, indirectly at the origin of the long periods of continental drought by imposing high atmospheric pressures. As for the fifth hypothesis of cold or frozen deserts, as absurd as this assertion may appear in present-day Australia, they existed several million years ago. Geomorphologists thus explain a number of spectacular rock formations, from the Mount Olga or Uluru to the over-deepened wave of the wind rocks, by involving a thaw of (peri)glacial formations followed by wind action over a long period. The sand ridges have a trend of SSE-NNW and continue parallel for great distances.<ref>{{Cite web|url=http://www.environment.gov.au/|title=Department of Agriculture, Water and the Environment|website=Department of Agriculture, Water and the Environment}}</ref>

==Biodiversity== ===Vegetation=== [[File:Mount Conner - panoramio.jpg|thumb|left|A view of Mount Conner with typical tussock vegetation in the foreground]] Two types of semi-desert, referred to as "grassland" in Australia, occur in the Australian deserts: tussock or Mitchell grasslands are found in the desert areas of the Northern Territory, South Australia and western Queensland. The annual precipitation that falls on these marl and alluvial soils covered with grasses of the ''Astrebla'' genus ranges from {{convert|150 to 500|mm|abbr=on|round=0.5}}. Trees cannot take root on the heavy clay soils, and they are riddled with bushfires. Spinifex or hummock semi-desert grows spiny- headed grasses (''Spinifex'') in clumps, next to free areas as green ''Triodia pungens'' and blue-grey ''Triodia basedowii''. ''Zygochloa'' dominates on the sand dunes of the Simpson, Strzelecki and Tirari Deserts. In large areas of desert, semi-desert grasslands with mulga bushes (''Acacia aneura'') predominate.<ref>[http://www.aridzonetrees.com/AZT%20Interactive%20Buttons/Tree%20Index/Cut%20sheets/Acacia/Acacia%20aneura.htm Arid Zone Trees] {{webarchive |url=https://web.archive.org/web/20070610101802/http://www.aridzonetrees.com/AZT%20Interactive%20Buttons/Tree%20Index/Cut%20sheets/Acacia/Acacia%20aneura.htm |date=June 10, 2007 }}</ref>
Semi-desert savannas with low-growing acacia species cover large areas in the south of the arid zone, where 200 to 500 mm of precipitation falls in winter and summer. The acacia species, called mulga, grow on the plains, mountain slopes and hills of the deserts. In connection with the bushfires, which are mainly ignited by the spinifex grasses, the non-resistant mulga bushes burn, which then no longer grow back. There is evidence that Aboriginal people did not start bushfires in mulga landscapes.{{cn|date=November 2025}} The desert areas covered by mulga are also threatened by deforestation, extensive livestock farming and fuel wood production. At the eastern end of the arid zone is the so-called witchetty bush. This area is home to the endemic species of acacia, ''Acacia kempeana'', which feeds the wood borer larva, the witchetty maggot, up to three inches in size. It is high in protein and was an important part of the Aboriginal diet.<ref>{{cite web|url=https://bie.ala.org.au/species/http://id.biodiversity.org.au/node/apni/2894166#names|title=''Acacia kempeana'' F.Muell.|access-date=12 May 2019|work=Atlas of Living Australia|publisher=Global Biodiversity Information Facility}}</ref>
Eucalyptus woodland thrives along the dry riverbeds. Grasses grow on the soil under the eucalypts. Chenopodiaceae shrubs, which usually do not exceed {{convert|1.5|m|ft|abbr=on|round=0.5}} in height, are found in the southern desert areas. They are salt plants that grow on both dry and saline soils. In the deserts there are permanent or percolating patches of freshwater formed in rocky areas or in sandstone canyons. Bluebush and saltbush species grow in heavier soils. Between the sand ridges, the areas of wooded steppe consist of ''Eucalyptus gongylocarpa'', ''Eucalyptus youngiana'', and ''Acacia aneura'' (mulga) shrubs scattered over areas of resilient spinifex grasses, particularly ''Triodia basedowii''. Most of the area is covered by hummock grasslands (''Triodia spp.''), with a few eucalypts, acacias, grevilleas, and bloodwoods (''Corymbia chippendalei'' and ''Corymbia opaca'') are found on sand hills. The vegetation of the dunefields of the Tirari Desert is dominated by either sandhill wattle (''Acacia ligulata'') or sandhill cane-grass (''Zygochloa paradoxa''), which occur on the crests and slopes of dunes. Tall, open shrubland also occurs on the slopes.<ref name="Biodiversity Strategy Draft p34">{{cite web| url = http://www.environment.sa.gov.au/biodiversity/pdfs/sa_aridlands_biostrat_draft_sandy_desert.pdf| title = South Australian Arid Lands Biodiversity Strategy Draft| page = 34| publisher = The Department for Environment and Heritage (Federal Government of Australia) and South Australian Arid Lands Natural Resources Management Board| access-date = 2008-06-23| archive-url = https://web.archive.org/web/20080625092457/http://www.environment.sa.gov.au/biodiversity/pdfs/sa_aridlands_biostrat_draft_sandy_desert.pdf| archive-date = 25 June 2008}}</ref>
In drier areas, species including old man saltbush (''Atriplex nummularia''), cottonbush (''Maireana aphylla'') and Queensland bluebush (''Chenopodium auricomum'') form a sparse, open shrubland, whereas swamps and depressions are frequently associated with swamp cane-grass (''Eragrostis australasica'') and lignum (''Muehlenbeckia florulenta''). The intermittent watercourses and permanent waterholes associated with tributaries of Cooper Creek support woodland dominated by river red gum (''Eucalyptus camaldulensis'') and coolibah (''Eucalyptus coolabah'').<ref name="Biodiversity Strategy Draft p17">{{cite web| url = http://www.environment.sa.gov.au/biodiversity/pdfs/sa_aridlands_biostrat_draft_sandy_desert.pdf| title = South Australian Arid Lands Biodiversity Strategy Draft| page = 17| publisher = The Department for Environment and Heritage (Federal Government of Australia) and South Australian Arid Lands Natural Resources Management Board| access-date = 2008-06-27| archive-url = https://web.archive.org/web/20080625092457/http://www.environment.sa.gov.au/biodiversity/pdfs/sa_aridlands_biostrat_draft_sandy_desert.pdf| archive-date = 25 June 2008}}</ref> Numerous salt lakes form after heavy rainfall and at times fill the underlying salt flats. The salt lakes occupy relatively small areas in the desert areas. For example, a major salt lake is Lake Eyre, which spans areas of the Gibson and Tirari Deserts and fills up completely and then dries up about once every 25 years. Seventeen headwaters have formed in the deserts as a result of the subsurface Great Artesian Basin, one of the largest freshwater basins in the world. The water coming out of the springs is rich in minerals. The springs partially form the habitat of endemic fish and the spring area is overgrown with rare plants. Numerous springs have dried up due to extensive agricultural use in the last 100 years. Threats to biodiversity include wildfires, feral animals, weeds, and uncontrolled grazing.{{Citation needed|date=November 2024}}

===Wildlife=== Significantly fewer animals live in the Australian deserts than in the Australian coastal regions. The most common creatures in Australia's arid regions are insects, such as termites and ants, which are of great importance to the ecology. Animals in the desert include feral camels, dingoes, goannas (including the large perentie) and numerous species of lizards and birds. Mammals include bilbies, mulgara, common brushtail possum, rufous hare-wallaby, burrowing bettong, the black-flanked rock-wallaby, marsupial moles, rufous hare-wallabies, yellow-footed rock wallaby, western grey kangaroos, and red kangaroos. Some of the bird-life found within the desert include the rare Alexandra's parrot, wedge-tailed eagles, Australian bustard, the mulga parrot, the scarlet-chested parrot and the chestnut-breasted whiteface (''Aphelocephala pectoralis'') found on the eastern edge of the Great Victoria Desert and the malleefowl of Mamungari Conservation Park.{{Citation needed|date=November 2024}}
About 103 species of mammals lived there at the time of European colonization, of which 19 are extinct, such as the desert bandicoot (''Perameles eremiana''), the numbat (''Myrmecobius fasciatus'') and the long-tailed bouncy mouse (''Notomys longicaudatus'').<ref name=ntgov>{{cite web | url = http://www.nt.gov.au/nreta/wildlife/animals/threatened/pdf/mammals/longtailed_hoppingmouse_ex.pdf | title = ''Notomys longicaudatus'' | access-date = 2011-04-17 | last = Pavey | first = Chris | date = May 2006 | publisher = Department of Natural Resources, Environment and the Arts, Northern Territory Government | archive-url = https://web.archive.org/web/20080903060007/http://www.nt.gov.au/nreta/wildlife/animals/threatened/pdf/mammals/longtailed_hoppingmouse_ex.pdf | archive-date = 2008-09-03 }}</ref> The main survivors are small rodents, insectivorous bats, marsupials, kangaroos and wallabies. A major threat to vegetation are the free-roaming camels in the desert. Over 300 species of birds live in the desert areas, including emus, ratites, parrots, cockatoos, owls and raptors. The desert includes many types of lizards, including the vulnerable great desert skink (''Egernia kintorei''), the Central Ranges taipan (discovered in 2007), and a number of small marsupials, including the endangered sandhill dunnart ''(Sminthopsis psammophila)'' and the crest-tailed mulgara ''(Dasycercus cristicauda)''. One way to survive here is to burrow into the sands, as a number of the desert's animals, including the southern marsupial mole ''(Notoryctes typhlops)'', and the water-holding frog do.{{Citation needed|date=November 2024}}
Reptiles live in large numbers in the deserts, for example the woma python, thorny devil, bearded dragon, monitor lizard, frilled dragon and geckos. Frog species that have adapted to drought, such as the desert trilling frog (''Neobatrachus centralis'') and the desert tree frog (''Litoria rubella''), can also occur. The most numerous species of lizards in the world can be found in the Australian desert, there are over 40 species of them there. In addition to fish, the few permanent freshwater holes are also home to mussels, crustaceans and insects. 34 species of fish occur in Lake Eyre and others at the artesian springs (e.g. at Dalhousie Springs in South Australia). Over 40 species of frogs have been observed after heavy rains.{{Citation needed|date=November 2024}}

==Mining== Other than agriculture and tourism, the primary economic activity in the vast and sparsely settled desert is mining. Owing to the almost complete absence of mountain building and glaciation since the Permian (in many areas since the Cambrian) ages, the outback is extremely rich in iron, aluminum, manganese and uranium ores, and also contains major deposits of gold, nickel, copper, lead and zinc ores. Because of its size, the value of grazing and mining is considerable. Major mines and mining areas in the Outback include opals at Coober Pedy, Lightning Ridge and White Cliffs, metals at Broken Hill, Tennant Creek, Olympic Dam and the remote Challenger Mine. Oil and gas are extracted in the Cooper Basin around Moomba.

The Pilbara region's economy is dominated by mining and petroleum industries.<ref>''The Pilbara's oil and gas industry is the region's largest export industry earning $5.0 billion in 2004/05 accounting for over 96% of the State's production.'' source – [http://www.pdc.wa.gov.au/industry/types-of-industries/oil-and-gas.aspx WA.gov.au] {{webarchive|url=https://web.archive.org/web/20080719184734/http://www.pdc.wa.gov.au/industry/types-of-industries/oil-and-gas.aspx |date=19 July 2008 }}</ref> Most of Australia's iron ore is also mined in the Pilbara and it also has one of the world's major manganese mines.{{Citation needed|date=November 2024}} {{Panorama|image=File:Outback view from Chambers Pillar.jpg|width= 750|height= 150|caption=View of dunefields and mesa, Central Australia}}
==Transport== thumb|A roadway within the red desert. The outback is reticulated by historic tracks with excellent bitumen surface and well-maintained dirt roads. The Stuart Highway runs from north to south through the centre of the continent, roughly paralleled by the Tarcoola-Darwin railway line. There is a proposal to develop some of the roads running from the south-west to the north-east to create an all-weather road named the Outback Highway, crossing the continent diagonally from Laverton, Western Australia (north of Kalgoorlie), through the Northern Territory to Winton, in Queensland. Air transport is relied on for mail delivery in some areas, owing to sparse settlement and wet-season road closures. Most outback mines have an airstrip and many have a fly-in fly-out workforce.{{Citation needed|date=November 2024}}
Roads in the desert include: {{Div col|small=yes}} * Birdsville Track * Burke Developmental Road * Canning Stock Route * Colson Track * Connie Sue Highway * French Line * Gary Highway * Gibb River Road * Great Central Road * Gunbarrel Highway * Kalumburu Road * Kidman Way * Lasseter Highway * Oodnadatta Track * Peninsula Developmental Road * Plenty Highway * Sandover Highway * Strzelecki Track * Talawana Track * Tanami Track {{div col end}}
==Towns== Although the desert covers about three-quarters of the continent, it only supports around 800,000 residents – less than 5% of the Australian population. In addition, there are approximately 1,200 small Indigenous communities, of which almost half have a population of fewer than 100 people. The Royal Flying Doctor Service (RFDS) started service in 1928 and helps people who live in the outback of Australia. In former times, serious injuries or illnesses often meant death due to the lack of proper medical facilities and trained personnel. Young Indigenous adults from the Gibson Desert region work in the Wilurarra Creative programs to maintain and develop their culture. Indigenous Australians in the desert regions include the Kogara, the Mirning and the Pitjantjatjara. Aboriginal populations have been increasing in this region.<ref name="Wilurarra Creative">[https://www.wilurarra.com.au/ Wilurarra Creative]</ref>
