Kangaroos and wallabies are marsupials that belong to a small group of animals called macropods. They are only found naturally in Australia and Papua New Guinea.Most macropods have hind legs larger than their forelimbs, large hind feet, and long muscular tails which they use for balance. Rock-wallabies live among piles of boulders, rocky hills and cliffs. 2  Tree-kangaroos (two species of which live in Australia) are found in the mountainous rainforests of north Queensland. 3  Smaller species of wallabies and kangaroos live in a wide range of habitats, from desert to woodland to rainforest.
