The quokka (Setonix brachyurus) is a small macropod about the size of a domestic cat. Like kangaroos and wallabies, the quokka is herbivorous and mainly nocturnal.
In the wild, it survives in only in the South-West of Western Australia, with a number of small scattered populations on the mainland, one large population on Rottnest Island and a smaller population on Bald Island near Albany. Both of these islands are fox and cat free.
The quokka has no fear of humans and it is common for it to approach them closely, particularly on Rottnest Island.
