This species is distributed from the islands of Timor (Indonesia and Timor Leste), Wetar and Leti (both to Indonesia) through the Kai Islands and a number of the Moluccan Islands of Indonesia (including: Ambon, Buru, and Seram); it is present on the islands of Misool, Waigeo, Batanta, and Salawati (all Indonesia), and ranges over much of the northern part of the island of New Guinea (Indonesia and Papua New Guinea), including a number of offshore islands. It ranges as far east as the Bismarck Archipelago, Papua New Guinea, where it is present on many islands including the islands of New Britain and New Ireland. It also occurs on many of the Solomon Islands.

Many of the insular island populations are the result of prehistorical introductions, possibly including: Timor, Seram, Buru, Sanana, the Kai Islands, the Bismarck Archipelago, and the Solomon Island chain.
