This species has also been recorded as established in Hawaii and from various islands in Wallacea (e.g. In New Zealand, the introduced populations may number less than 1000.

They have also been introduced to Palau and New Zealand. Outside Australia, they have been introduced to Singapore, where their numbers have been estimated to be between 5. Within Australia, sulphur-crested cockatoos of the nominate race have also been introduced to Perth, which is far outside the natural range. Northern Australia from West Australia to the Gulf of Carpentaria Restricted to the Aru Islands in the Maluku province of eastern Indonesia Except for highland areas, they occur throughout most of New Guinea and on nearby smaller islands such as Waigeo, Misool and Aru, and various islands in the Cenderawasih Bay and Milne Bay.įound in New Guinea and the surrounding islands They are numerous in suburban habitats in cities such as Adelaide, Melbourne, Canberra, Sydney and Brisbane. In Australia, sulphur-crested cockatoos can be found widely in the north and east, ranging from the Kimberley to as far south as Tasmania, but avoiding arid inland areas with few trees. A highly intelligent bird, they are well known in aviculture, although they can be demanding pets. They can be locally very numerous, leading to them sometimes being considered pests.
