What You'll Learn

Population and demographics
The Outback is a remote, vast, and sparsely populated area of Australia. It covers most of Australia, including anywhere outside of densely populated coastal areas. The Outback extends from the northern to southern Australian coastlines and includes a variety of climatic zones, from tropical and monsoonal climates in the north to semi-arid and temperate climates in the south. The "red centre" of the Outback is arid. The Outback is also deeply ingrained in Australian heritage, history, and folklore.
The population of the Outback in Australia declined from 700,000 in 1996 to 690,000 in 2006, with the latest estimates placing the population at 607,000 people. The Outback is thus a sparsely populated area, with a low human population density and a largely intact natural environment. The population density of the Outback Region in South Australia was 0.015 per km² as of the 2006 census. The Outback Northern Territory saw the largest population decline, while the Kimberley and Pilbara regions experienced population increases during the same period.
The Outback has a high proportion of indigenous inhabitants, with 17% of the total population identifying as indigenous Aboriginal Australians. This population has retained 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. Four of the five Aboriginal councils of South Australia fall within the boundaries of the Outback Region.
The Outback has a disproportionately male population, with a sex ratio of 1040 males for every 1000 females. The Royal Flying Doctor Service (RFDS) assists those living in the Outback, providing medical and ambulance services to remote areas. In terms of education, the small number of children in many Outback communities has led to alternative schooling methods, such as the School of the Air, which utilises satellite telecommunication for remote learning.
Tourism is a significant industry in the Outback, with regional tourism contributing substantially to national tourism incomes. Tourism Australia promotes nature-based and Indigenous-led experiences to attract domestic and international travellers. In the 2015-2016 financial year, 815,000 visitors spent $988 million in the Northern Territory alone. Popular tourist destinations in the Outback include Devils Marbles, Kakadu National Park, Kata Tjuta (The Olgas), MacDonnell Ranges, and Uluru (Ayers Rock).

Geography and climate
The Outback is a remote, huge, and sparsely populated area of Australia. Covering more than 5.3 million square kilometres, it is estimated that 5% to 17% of the population lives there, with the total population estimated at 607,000 people. The Outback is considered to be anywhere outside of the densely populated coastal areas of Australia. It stretches across several states: the Northern Territory, Western Australia, South Australia, Queensland, and New South Wales.
The Outback is unified by a combination of factors, most notably a low human population density, a largely intact natural environment, and low-intensity land uses. The region is extremely diverse, with arid red deserts, tropical climates in the north, savannas, woodlands, rocky hills, floodplains, and vast stretches of wilderness. It is made up of 10 deserts, subtropical savanna, and the largest temperate woodland on Earth. The Outback receives a fair amount of rain, from 150 mm in the arid areas to 500 mm in semi-tropical parts, although some years there is no rain at rain at all, and other years there are floods.
The Outback is deeply ingrained in Australian heritage, history, and folklore, and is particularly prevalent in Australian art. The region is home to Aboriginal Australians, with a history of up to 68,000 years. There are over 150 Indigenous languages spoken across Central Australia, and 17% of the Outback population are from indigenous Aboriginal tribes.
The Outback's main economic activities include agriculture, mining, and tourism. The largest industry across the Outback is pastoralism, in which cattle, sheep, and sometimes goats are grazed in mostly intact, natural ecosystems. The Outback is also extremely rich in iron, aluminium, manganese, and uranium ores, and also contains major deposits of gold, nickel, copper, lead, and zinc ores.

Natural resources and industry
The Outback is a vast, remote inland area of Australia, covering approximately 5.6 million square kilometres or over two-thirds of the continent. It is sparsely populated, with a total population of around 600,000-800,000 people, of which 17% are indigenous. The Outback is characterised by diverse landscapes, including red rock deserts, grassland plains, and woodlands, and supports a unique array of plant and animal species, many of which are endemic to the region.
The natural resources and industries of the Outback are varied and play a significant role in the region's economy. Here are some key sectors:
- Mining and Minerals: The Outback is extremely rich in natural resources due to its geological history. It contains significant deposits of iron ore, aluminium, manganese, and uranium ores, as well as gold, nickel, copper, lead, and zinc ores. Major mining areas include Coober Pedy, Lightning Ridge, White Cliffs, Broken Hill, and the Challenger Mine. The Argyle diamond mine in Western Australia was once the world's largest producer of natural diamonds.
- Oil and Gas: The Cooper Basin in the Outback is a significant source of oil and gas extraction. The Pilbara region in Western Australia is particularly known for its oil, gas, and petroleum industries, which are a major source of export revenue.
- Agriculture and Grazing: The Outback supports extensive pastoralism or livestock grazing, with cattle, sheep, and goat farming being the largest industry in terms of area occupied. The marginally fertile rangelands are used for grazing, and many Outback pastoral properties are certified as organic livestock producers due to the lack of fertiliser and pesticide use.
- Tourism: Tourism is a significant industry in the Outback, attracting both domestic and international visitors. The unique landscapes, natural beauty, and Indigenous culture of the region are marketed as desirable experiences. Regions such as Alice Springs, Tennant Creek, and Arnhem Land are popular tourist destinations, contributing tens of billions of dollars to the economy.
- Fossil Sites: Riversleigh in Queensland, within the Outback region, is a renowned fossil site recognised as a World Heritage Site. It contains fossil remains of ancient mammals, birds, and reptiles, attracting scientific and tourism interest.
- Renewable Energy Potential: While Australia currently relies heavily on fossil fuels, particularly coal, for its energy, there is growing potential for renewable energy sources such as wind, solar, and tidal power. The Outback, with its vast open spaces and natural advantages, could play a role in harnessing these renewable energy resources in the future.

History and culture
The Outback is deeply ingrained in Australian heritage, history, and folklore. The region covers a vast area of the country, stretching across deserts, plains, and mountains. While there’s no exact boundary, the Outback generally refers to the inland areas of Australia, away from the coastal cities. The term "Outback" has been used to refer to these arid regions since the 19th century. Other popular terms include "the bush", "back o'Bourke", and "the never-never".
The Outback is home to a small but resilient population, consisting of both Aboriginal peoples and settlers. Aboriginal Australians have lived in the Outback for at least 50,000 to 60,000 years and occupied all Outback regions when Europeans first entered central Australia in the 1800s. Today, the Outback is home to the majority of the Aboriginal population. Aboriginal culture, art, and mythology are deeply rooted in the arid landscape of the Outback. Visitors can experience this rich cultural history by visiting sacred sites, viewing ancient rock art, and hearing stories passed down through countless generations. Aboriginal-guided tours offer a fantastic way to learn about Aboriginal traditions and their deep connections to the land.
European explorers tended to avoid the Outback, favouring the lush coastal regions of Australia. The first European exploration of the Outback is credited to Gregory Blaxland, William Lawson, and William Charles Wentworth, who in 1813 explored a trail through the Great Dividing Range in New South Wales. Settlement in the Outback greatly increased after the expeditions of Scottish explorer John McDouall Stuart in the 1850s and 1860s, which led to the establishment of the Overland Telegraph in 1872.
The Outback contains a wealth of ecologically rich ecosystems, including distinctive wildlife and important water sources. The region is also extremely rich in natural resources, including iron, aluminium, manganese, and uranium ores, as well as deposits of gold, nickel, copper, lead, and zinc ores. The value of grazing and mining is considerable due to the Outback's size.
