How did Australia get mountains?
Under the flat plain, the Earth’s crust became thinner and weaker. This allowed hot magma from deep below to rise up. The magma heated the crust and added new lighter rocks, so the crust expanded upwards to form a plateau nearly two kilometres high. This new highlands was the beginning of the Australian Alps.
Why are Australia’s mountains so low?
Australia was part of the supercontinent of Gondwana, lying in the interior of the landmass. The mountain ranges were slowly worn down to a low-lying plain and very few rocks of this period are preserved in the alpine region.

Why is most of Australia uninhabited?
Australia’s population density is low because most of the country’s interior is desert (also known as the outback) and presents extremely difficult living conditions.
Why is the middle of Australia uninhabitable?
One reason behind this large landmass being so desolate is the shortage of rainfall. More than two-third part of the country only receives less than 500 mm annual rain. This arid, uninhabitable part of Australia lies in the middle of the continent (the Outback), away from the coasts.
