The Dinagat bushy-tailed cloud rat (Crateromys australis), is a new species of bushy-tailed cloud rat in the family Muridae. It is found only on Dinagat Island in the Philippines. Its natural habitat is subtropical or tropical dry forests. The main threat is habitat loss caused by deforestation and chromite mining. It was long known only by the holotype collected by Dioscoro S. Rabor in 1975 until it was rediscovered and filmed by Czech zoologist Milada Řeháková and her husband in January 2012.
