Outback
The Outback is a remote, vast, sparsely populated area of Australia. The Outback is more remote than what Australians call “the bush”. While often envisaged as being arid, the Outback regions extend from the northern to southern Australian coastlines and encompass a number of climatic zones, including tropical and monsoonal climates in northern areas, arid areas in the "red centre" and semi-arid and temperate climates in southerly regions. The total population is estimated at 607,000 people.
Geographically, the Outback is unified by a combination of factors, most notably a low human population density, a largely intact natural environment and, in many places, low-intensity land uses, such as pastoralism in which production is reliant on the natural environment. The Outback is deeply ingrained in Australian heritage, history and folklore. In Australian art the subject of the Outback has been vogue, particularly in the 1940s. In 2009, as part of the Q150 celebrations, the Queensland Outback was announced as one of the Q150 Icons of Queensland for its role as a "natural attraction".
History
have lived in the Outback for at least 50,000 years and occupied all Outback regions, including the driest deserts, when Europeans first entered central Australia in the 1800s. Many Aboriginal Australians retain strong physical and cultural links to their traditional country and are legally recognised as the Traditional Owners of large parts of the Outback under Commonwealth Native Title legislation.Early European exploration of inland Australia was sporadic. More focus was on the more accessible and fertile coastal areas. The first party to successfully cross the Blue Mountains just outside Sydney was led by Gregory Blaxland in 1813, 25 years after the colony was established. People, starting with John Oxley in 1817, 1818 and 1821, followed by Charles Sturt from 1829 to 1830, attempted to follow the westward-flowing rivers to find an "inland sea", but these were found to all flow into the Murray River and Darling River, which turn south.
From 1858 onwards, the so-called "Afghan" cameleers and their beasts played an instrumental role in opening up the Outback and helping to build infrastructure.
Over the period 1858 to 1861, John McDouall Stuart led six expeditions north from Adelaide, South Australia into the Outback, culminating in successfully reaching the north coast of Australia and returning without the loss of any of the party's members' lives. This contrasts with the ill-fated Burke and Wills expedition in 1860–61 which was much better funded, but resulted in the deaths of three of the members of the transcontinental party.
The Overland Telegraph line was constructed in the 1870s along the route identified by Stuart.
In 1865, the surveyor George Goyder, using changes in vegetation patterns, mapped a line in South Australia, north of which he considered rainfall to be too unreliable to support agriculture.
Exploration of the Outback continued in the 1950s when Len Beadell explored, surveyed and built many roads in support of the nuclear weapons tests at Emu Field and Maralinga and rocket testing on the Woomera Prohibited Area. Mineral exploration continues as new mineral deposits are identified and developed.
2002 was declared the Year of the Outback. While the early explorers used horses to cross the Outback, the first woman to make the journey riding a horse was Anna Hingley, who rode from Broome to Cairns in 2006.
Environment
Global significance
The paucity of industrial land use has led to the Outback being recognised globally as one of the largest remaining intact natural areas on Earth. Global "Human Footprint" and wilderness reviews highlight the importance of Outback Australia as one of the world's large natural areas, along with the Boreal forests and Tundra regions in North America, the Sahara and Gobi deserts and the tropical forests of the Amazon and Congo Basins.The savanna of northern Australia are the largest, intact savanna regions in the world. In the south, the Great Western Woodlands, which occupy, an area larger than all of England and Wales, are the largest remaining temperate woodland left on Earth.
Major ecosystems
Reflecting the wide climatic and geological variation, the Outback contains a wealth of distinctive and ecologically rich ecosystems. Major land types include:- the Kimberley and Pilbara regions in northern Western Australia,
- sub-tropical savanna landscape of the Top End,
- ephemeral water courses of the Channel Country in western Queensland,
- the ten deserts in central and western Australia,
- the Inland Ranges, such as the MacDonnell Ranges, which provide topographic variation across the flat plains,
- the flat Nullarbor Plain north of the Great Australian Bight, and
- the Great Western Woodlands in southern Western Australia.
Wildlife
Birdlife is prolific, most often seen at waterholes at dawn and dusk. Huge flocks of budgerigars, cockatoos, corellas and galahs are often sighted. On bare ground or roads during the winter, various species of snakes and lizards bask in the sun, but they are rarely seen during the summer months.
Feral animals such as camels thrive in central Australia, brought to Australia by pastoralists and explorers, along with the early Afghan drivers. Feral horses known as 'brumbies' are station horses that have run wild. Feral pigs, foxes, cats, goats and rabbits and other imported animals are also degrading the environment, so time and money is spent eradicating them in an attempt to help protect fragile rangelands.
The Outback is home to a diverse set of animal species, such as the kangaroo, emu and dingo. The Dingo Fence was built to restrict movements of dingoes and wild dogs into agricultural areas towards the south east of the continent. The marginally fertile parts are primarily utilised as rangelands and have been traditionally used for sheep or cattle grazing, on cattle stations which are leased from the Federal Government. While small areas of the outback consist of clay soils the majority has exceedingly infertile palaeosols.
Riversleigh, in Queensland, is one of Australia's most renowned fossil sites and was recorded as a World Heritage site in 1994. The area contains fossil remains of ancient mammals, birds and reptiles of Oligocene and Miocene age.
Industry
Pastoralism
The largest industry across the Outback, in terms of the area occupied, is pastoralism, in which cattle, sheep, and sometimes goats are grazed in mostly intact, natural ecosystems. Widespread use of bore water, obtained from underground aquifers, including the Great Artesian Basin, has enabled livestock to be grazed across vast areas in which no permanent surface water exists naturally.Capitalising on the lack of pasture improvement and absence of fertiliser and pesticide use, many Outback pastoral properties are certified as organic livestock producers. In 2014,, most of which is in Outback Australia, was fully certified as organic farm production, making Australia the largest certified organic production area in the world.
Tourism
Tourism is a major industry across the Outback, and commonwealth and state tourism agencies explicitly target Outback Australia as a desirable destination for domestic and international travellers. There is no breakdown of tourism revenues for the "Outback" per se. However, regional tourism is a major component of national tourism incomes. Tourism Australia explicitly markets nature-based and Indigenous-led experiences to tourists. In the 2015–2016 financial year, 815,000 visitors spent $988 million while on holidays in the Northern Territory alone.There are many popular tourist attractions in the Outback. Some of the well known destinations include Devils Marbles, Kakadu National Park, Kata Tjuta, MacDonnell Ranges and Uluru.
Mining
Other than agriculture and tourism, the main economic activity in this vast and sparsely settled area is mining. Owing to the almost complete absence of mountain building and glaciation since the Permian ages, the outback is extremely rich in iron, aluminium, 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.In Western Australia the Argyle diamond mine in the Kimberley was once the world's biggest producer of natural diamonds and contributed approximately one-third of the world's natural supply, but was closed down in 2020 due to financial reasons. The Pilbara region's economy is dominated by mining and petroleum industries. The Pilbara's oil and gas industry is the region's largest export industry, earning $5.0 billion in 2004/05 and accounting for over 96% of the state's production. Most of Australia's iron ore is also mined in the Pilbara and it also has one of the world's major manganese mines.
Population
communities in outback regions, such as the Anangu Pitjantjatjara Yankunytjatjara lands in northern South Australia, have not been displaced as they have been in areas of intensive agriculture and large cities, in coastal areas.The total population of the Outback in Australia declined from 700,000 in 1996 to 690,000 in 2006. The largest decline was in the Outback Northern Territory, while the Kimberley and Pilbara showed population increases during the same period. The sex ratio is 1040 males for 1000 females and 17% of the total population is indigenous.
