Answer:
The Outback is the area in the middle of Australia that is mostly desert where fewer people live. Theoretically, it is classed as beginning north of the Flinders Ranges in South Australia and extending throughout the inland, to within a few hundred kilometres of the east and north coastlines, and virtually right to the western coast apart from in the southwest.
It is not all desolate. Many areas of the outback are valuable for sheep and cattle stations. There are rivers and creeks flowing through the outback,and permanent waterholes.
