The Land
Australia
Continent and country, and it isn't considered an island because of its size
Mountains and Plateaus
Australia is mostly flat except for the Great Dividing Range on the eastern coast.

Most of the Rivers begin in the Diving Range

It is also referred to as the outback
the three deserts are the Gibson, Sandy and Victoria
Towards the south coast, the Nullarbor Plain which means ¨no trees.¨it ends abruptly with a cliff on the Australian BIght
Central Lowlands
The central lowlands separates the outback and the Great Diving Range
contains arid grasslands and desert and stretches across the east central part of Australia
The Murray and Darling are the two rivers that supply water for farming year round because most of them dry up
