Finsch's monitor (Varanus finschi) is a species of Monitor Lizard found in New Guinea and Australia. Finsch's monitor was only known from Blanche Bay, Ralum and Massawa in New Britain. Further research on the available museum specimen enlarged the range of the species, which currently includes the Bismarck Archipelago (New Ireland), New Guinea and Queensland, Australia. Unfortunately, the specimen from Queensland lacks any fixed data on its locality, so the exact distribution of Finsch's Monitor in northern Australia remains unknown. Varanus finschi is found in multiple types of habitats: mangrove forest, inland forest, fresh cut clearings, coconut plantations and rocky beaches. It belongs to the subgenus Euprepiosaurus along with the closely related Ceram Mangrove and Peach Throat Monitor
