Wallabies are native to Australia, where they are found in all of the states and both territories, including the island state of Tasmania. Many species live in bushland, b â¦ ut there are also numerous varieties especially suited to rocky hillsides. Wallabies are actually grouped according to the habitat in which they live, so there are swamp wallabies, brush wallabies, and rock wallabies. Swamp wallabies inhabit fairly flat bushland areas which are reasonably open, unlike the brush wallaby which prefers more closed forest, with denser undergrowth.
