Although the shape of Australia is due largely to tectonic Earth movements and long term changes in sea level, most of its topography is a result of prolonged erosion by wind and water. … After the ice melted, parts of the continent subsided and formed sedimentary basins such as the Eromanga Basin in South Australia.

How did Australia evolve?
The continent was affected by glaciation around 330 Ma.

Why is Australia so flat?
