If you think New South Wales and Queensland are big, try Western Australia. It covers about 250 million hectares and has some of the oldest land features on the planet.
The coast stretches some 12,500 kilometres. And the variety of areas is vast - dry, arid areas, towering forests, coral reefs and woodlands.
