In which state do koalas live?

Koalas are native to Australia.

They are found throughout the states of Queensland, New South Wales and Victoria. European settlement resulted in their extinction in South Australia, but they have been reintroduced to parts of South Australia, where colonies are thriving. Small colonies have also been introduced to the southeast corner of Western Australia.

Koalas are not found in either Tasmania (Australia's island state) or in the Northern Territory.
