This species is endemic to Australia, where it occurs in New South Wales, Australia (formerly as far south as the Illawarra). It is present in suitable forests scattered throughout the escarpment, but it is no longer found in coastal forests. Upper altitudinal sites include the Dorrigo Plateau, Gibraltar Range, and Barrington Tops. It occurs up to 1,000 m asl. Feral populations exist on Kauwau Island, New Zealand (Maynes 2008).
