Range DescriptionThis species is known from Australia and the island of New Guinea (Papua New Guinea only). In Australia, it previously occurred though much of monsoonal northern areas, including a number of offshore islands (e.g., Groote Eylandt). Currently this species occurs in perhaps 20 per cent of historic range. It is restricted to the mainland within a thin strip of about 30 km of the coast in Western Australia and Northern Territory. It is also known from islands. The smallest island from which the species is currently known is 8,181 ha (Inglis Island) (Woinarski et al. 1999). In Western Australia, the species is only known from several localities. The range is apparently disjunct between the northern Western Australia segment and the northern Northern Territory segment, though there have not been extensive recent surveys in the region. In Northern Territory, it is now found on Cobourg Peninsula, Bathurst, Melville, and Inglis Islands, Groote Eylandt, and a small area in Kakadu National Park (Woinarski 2000, 2005). The species is also present on Bentinck Island, Queensland.
In Papua New Guinea, it is known only from two nearby localities (Penzara Village and Morehead) in southern Western Province, where it seems to be a distinct subspecies, C. p. randi. Surveys suggest that the species has a restricted distribution (Flannery 1995). It ranges from sea level to 60 m asl.
