Gilbert’s potoroo was once widespread throughout south-west Australia, but now is found only on the Mt Gardner headland at Two Peoples Bay Nature Reserve. Potorous tridactylus is widely distributed in southeastern Australia and Tasmania and can be found in coastal New South Wales, southeastern Queensland, coastal, near-coastal, and northeastern areas of Victoria, and the southwestern corner of Western Australia (Census of Australian Vertebrate Species 1995 Gilbert’s Potoroo is the rarest marsupial in the world, with around 100 individuals.

Then, in 2005, the decision was made to risk a couple of adults to establish an ‘ark’ population on 800ha Bald Island, 25km east of Two Peoples Bay. Insects and their larvae compose a meager 1-2% of the winter diet of P. tridactylus, but this can increase to 21% during the summer when insect abundance augments (Hume 1982 and Strahan 1995).
