The Great Dividing Range, or the Eastern Highlands, is Australia's most substantial mountain range and the fifth longest land-based range in the world.
It stretches more than 3,500 kilometres (2,175 mi) from Dauan Island in the Torres Strait off the northern tip of Cape York Peninsula, Queensland, running the entire length of the eastern coastline through New South Wales, then into Victoria and turning west, before finally fading into the central plain at the Grampians in western Victoria.
The width of the range varies from about 160 km (100 mi) to over 300 km (190 mi). The Greater Blue Mountains Area, Gondwana Rainforests, and Wet Tropics of Queensland World Heritage Areas are located in the range.
The Dividing Range does not consist of a single mountain range. It consists of a complex of mountain ranges, plateaus, upland areas and escarpments with an ancient and complex geological history.
In some places the terrain is relatively flat, consisting of very low hills. Typically the highlands range from 300 to 1,600 metres (980 to 5,250 ft) in height.
