Definitely not. There are not even millions of koalas.
There is only one species of koala (Phascolarctus Cinereus), and some disagreement about whether there are two or three sub-species, or indeed, whether there are any sub-species at all.
According to the Australian Koala Foundation, the generally accepted sub-species are:
- Phascolarctos Cinereus adustus - Northern Australia/Queensland
- Phascolarctos Cinereus cinereus - Intermediate/New South Wales
- Phascolarctos Cinereus victor - Southern/Victorian
