It is because Australia is an island. It is a secluded landmass with no immigration of animals from other parts of the world.

Sea levels were much lower than today. Animals could make their way from the Malay Archipelago. Australia's coast also stretched further into the Timor Sea. It is thought that the Aborigines originally reached Australia from these routes. Animals usually show people the way into new environments.

Australia also used to be part of Asia. Continental drift and raising sea levels caused the continent/island of Australia to become "lost" and the animals and the people on the land were in a way stuck where they were. Nature has a very clear rule about what to do in such a case. It is to adapt or to die. That is exactly what the animals did. They slowly started to adapt to the environment that they live in.
