The Northern Hairy-nosed Wombat is one of the world's most critically endangered species. It is the largest herbivorous burrowing mammal in the world and disappeared rapidly after the introduction of sheep, cattle and rabbits into Australia, due to competition for grass (their nutrition is based on almost 100% grass).
The Yellow-bellied Glider lives along the East coast of Australia, from Northern Queensland to Victoria. Although it's not currently listed as threatened, its habitat is being decimated in Victoria's alpine areas and populations in NSW are facing extinction.
Tasmanian Devils are threatened by Devil Facial Tumour Disease (DFTD). This disease currently afflicts three quarters of Tasmania's Devils but is absent from Devils in the Tarkine in Tasmania's North West.
