By early in the Cretaceous Period, Australia was already so flat and low that a major rise in sea level divided it into three landmasses as a shallow sea spread over the land. After the ice melted, parts of the continent subsided and formed sedimentary basins such as the Eromanga Basin in South Australia. Australia began its journey across the surface of the Earth as an isolated continent between about 55 and 10 million years ago, and continues to move north by about seven centimetres each year.Īustralia's present topography is the result of a long landscape history, which, fundamentally, started in the Permian Period when Australia was very near the South Pole, and much of the continent was glaciated by large ice caps. Northern Territory.The Finke River in central Australia is one of the oldest rivers in the world and salt lakes of the Yilgarn region in Western Australia are the remnants of a drainage pattern which was active before continental drift separated Australia from Antarctica. ![]() Geoscience Australia is the government's technical adviser on all aspects of geoscience, and custodian of the geographical and geological data and knowledge of the nation.
