The potoroo is known as the "rat" kangaroo with the appearance of a miniature Wallaby. Discovered in 1968 and offically recognised as a species in 1978. As it prefers to inhabit areas which have a high rainfall, the potoroo was once widespread in the north-east of New South Wales and along the ranges. But now they are only found within forests of New South Wales and the Queensland border due to a loss of natural habitat and an increase in predators. It is today considered an endangered species in New South Wales.
