What You'll Learn
Australia's lowest point, Lake Eyre, is 15m below sea level
Australia is the lowest continent in the world, with an average elevation of only 330 metres. Mount Kosciusko, Australia's highest peak, is 2228 metres above sea level. In contrast, the world's tallest mountain, Mount Everest, stands at 8848 metres above sea level.
Australia's lowest point is Lake Eyre, which is approximately 15 metres (49 feet) below sea level. Located in the deserts of central Australia, in northern South Australia, Lake Eyre is around 700 kilometres north of Adelaide and 400 kilometres from the nearest point along the South Australian coastline. The lake covers an area of 9000 square kilometres and is recognised as one of the most important sites for waterbirds in Australia. It is also known for its salt flats, which have been used for land speed record attempts.
Lake Eyre is part of the Lake Eyre Basin, one of the largest endorheic (internally draining) systems in the world. The lake itself is made up of two sections, Lake Eyre North and Lake Eyre South, joined by the narrow Goyder Channel. The lowest part of the lake is characterised by a salt pan formed by the seasonal expansion and evaporation of trapped waters. This salt crust, which is particularly thick in the lake's southern portions, has been measured at up to 46 centimetres in depth.
The lake was named after Edward John Eyre, the first European to see it in 1840. It was officially renamed in 2012 to include its Aboriginal name, Kati Thanda, in a policy of dual naming. The lake holds deep spiritual significance for the Arabana people, who hold the native title over most of the lake and its surrounding region. The eastern portion of the lake is allocated to the Dieri people.

The continent's average elevation is 330m above sea level
Australia is the lowest continent in the world, with an average elevation of 330 meters above sea level. This is in stark contrast to other continents, whose highest points are all more than twice the height of Australia's tallest mountain, Mount Kosciuszko, which stands at 2,228 meters above sea level. To put this into perspective, the world's tallest mountain, Mount Everest, reaches a staggering height of 8,848 meters above sea level, almost four times the height of Mount Kosciuszko.
Australia's low-lying landscape is a defining characteristic of the continent. The continent's flatness is due to its geological history and the fact that it has remained relatively stable tectonically for a long period of time. This stability has prevented the formation of large mountain ranges, resulting in the continent's relatively low elevation compared to other landmasses.
The lack of significant mountain ranges in Australia contributes to its overall low-lying nature. While the continent boasts some impressive mountain peaks, such as Mount Kosciuszko, these are considered relatively modest compared to the towering peaks found on other continents. Australia's terrain is characterized more by vast expanses of flat or gently sloping land, with a mix of deserts, grasslands, and coastal areas.
The average elevation of 330 meters above sea level has implications for Australia's climate and geography. Lower elevations generally result in warmer temperatures, and Australia is known for its hot and arid conditions in many regions. The flat terrain also allows for extensive inland drainage systems, with rivers flowing inland from the coastal areas. This has given rise to unique ecosystems and habitats found nowhere else on Earth.
While Australia's average elevation of 330 meters above sea level makes it the lowest continent, it does not mean that there are no variations in height across the landmass. There are still areas of higher ground and mountainous regions, particularly along the eastern coast, where the Great Dividing Range runs parallel to the coastline. These variations in elevation within the continent contribute to the diverse landscapes and environments found across Australia.

Mountain ranges in the north of Western Australia
Western Australia is known for its mountain ranges, which consist of old, eroded formations. The Stirling Range, located in southwest WA, northeast of Albany, is one of the most notable ranges in the region. Bluff Knoll, the highest peak in the Stirling Range, stands at 1,099 meters (3,609 feet). The Stirling Range National Park offers challenging trails, including the Bluff Knoll trail, which ascends 600 meters to the summit. The trail provides panoramic views of the surrounding landscapes and is a popular hiking destination.
The Hamersley Range in Karijini National Park is another significant mountain range in Western Australia. Mount Meharry, the highest point in Western Australia, reaches an elevation of 1,251 meters (4,104 feet). The region is known for its mining activities, producing iron ore, gold, diamonds, and bauxite.
The far northern regions of Western Australia experience a tropical monsoon climate, with heavy rains during the wet season followed by dry summers. This climate gives rise to the tropical savanna ecosystem, characterized by boab trees in the Kimberley region. The wet season creates temporary wetlands that serve as critical habitats for migratory birds, crocodiles, and other species.
The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a vast cordillera system in eastern Australia. It runs parallel to the east coast of Australia, stretching over 3,500 kilometers from Dauan Island in the Torres Strait to the Grampians region in Victoria. The range includes major cities such as Canberra, Toowoomba, and outer suburbs of Sydney, Melbourne, Brisbane, Gold Coast, and Cairns. It serves as a watershed for eastern Australia's river systems and provides water to the Great Artesian Basin in Queensland.

Central Australia is a flat plain
Australia is the lowest continent in the world, with an average elevation of only 330 metres above sea level. Its highest peak, Mount Kosciuszko, stands at 2228 metres above sea level, which is less than half the height of the world's tallest mountain, Mount Everest, at 8848 metres.
Central Australia, also known as the Red Centre, is an informal term for a large, arid region in the geographic centre of the country. It is often associated with the Outback, and in its broadest sense, it can refer to any undeveloped region in inland Australia. The region is characterised by its desert environment, receiving just 150 millimetres of rainfall annually.
The landscape of Central Australia is indeed dominated by flat plains. The Nullarbor Plain, for example, is an expansive, almost treeless, arid region in southern Australia. It is the world's largest single exposure of limestone bedrock, covering around 200,000 square kilometres. The plain has a desert climate, with scorching hot summers and freezing winters inland. The mean annual rainfall at Cook in the Nullarbor Plain is 184.1 millimetres, with most rain falling between May and August.
The Carpentaria Plains, occupying the basin of the same name, also form a narrow lowland corridor. In the south, these plains take the form of rolling plains underlain by heavy gray lime-enriched soils. In the north, there are extensive flat depositional plains, some of which are related to swamps from the Pleistocene Epoch.
Additionally, the gibber plains of Central Australia, particularly around the Lake Eyre depression, are characteristic of the region. These plains are the result of the disintegration of silcrete, a hard rock residue that once extended over vast areas. The stony debris from this process has contributed to the unique landscape of Central Australia.

The highest point is Mount Kosciuszko, 2228m above sea level
The highest point in mainland Australia is Mount Kosciuszko, which rises to 2228 metres (7310 ft) above sea level. It is located on the Main Range of the Snowy Mountains in Kosciuszko National Park, in New South Wales, near the border with Victoria. Mount Kosciuszko was named by the Polish explorer Paweł (Paul) Edmund Strzelecki in 1840, in honour of Tadeusz Kościuszko, a general and hero of the Kościuszko Uprising and the American Revolutionary War. Strzelecki's decision to name the mountain after Kościuszko was due to its perceived resemblance to the Kościuszko Mound in Kraków, Poland.
Mount Kosciuszko is ranked 35th by topographic isolation. It is accessible via a walking path from Thredbo, which takes around 3 to 3.5 hours for a round trip. The walking path is especially popular during the summer, and it is a mesh walkway designed to protect the native vegetation and prevent erosion. The peak can also be approached from Charlotte Pass, which is a 7.6-kilometre (5-mile) walk to Rawson Pass at 2100 metres (6900 ft) above sea level. From Rawson Pass, it is a further 1.4 kilometres (0.87 miles) to the summit.
Mount Kosciuszko is not only the highest point in mainland Australia but also the name of a national park in the Australian Alps National Parks and Reserves. The mountain is located within this park, which is home to a variety of native flora and fauna. The summit offers panoramic views of the surrounding mountains and valleys, and on a clear day, hikers can see as far as the Victorian Alps and the NSW South Coast.
