Major Landform regions of Australia See also. The Australian continent is broadly divided into 4 major landform regions, each of which is comprised of smaller-scale constituent landform regions-eastern highlands, central lowlands, western plateau and the coastal plains.he lowest point on the Australian continent, Lake Eyre, is also situated in this region. It also includes inselbergs such as Uluru and Kata Tjuta. About 38 % of the Australian continent is less than 200 m above sea level (so far), much of it in the Central lowlands.
Coastal Plains. The Coastal Plains are to the eastern edge of Australia. The Coastal plains out of all the landforms, is the most populated and dense. Being a flat and and a low-lying area on the Australian continent, this helps to develop a greater amount of species and landmass.ith the continent divided into 4 major landform areas. Each region is made up of smaller component landforms. Through deep seismic surveys, scientists have been able to obtain a much clearer picture of Australia's geological past.
