Great Dividing Range
Formed during the Carboniferous Period as part of the supercontinent Pangaea as Gondwana collided with other landmasses, Eastern Australia's main watershed, the Great Dividing Range, comprises a 3,700-kilometre cordillera system of low mountain ranges, plateaus, escarpments and upland areas running roughly parallel to the Queensland, New South Wales, and Victorian coasts from Dauan Island off the Queensland's northeastern tip to the Grampians in Victoria.
After a relatively narrow profile in the Cape York Peninsula, the uplands widen, varying in width from around 160 kilometres to over 300 kilometres. The range's crest is the boundary between the drainage basins of rivers that drain east into the Pacific Ocean and westwards towards the Gulf of Carpentaria, the Lake Eyre basin or the Murray-Darling system. Still, the name can refer to both the watershed and all of the uplands between Australia's east coast and the continent's inland plains and lowlands.
