Depends on where they are. Australia zoo, not far from me, have clean koalas. They are kept separate from the Chlamydia clinic at the zoo (funded by Russell Crowe) where the infected ones are treated. One reason for an increase in the disease in the wild is the destruction of habitat ergo forcing more contact among the colonies.To give you a hint as to how cuddly Koalas are, a principal cause of death in the wild is Chlamydia……
So….you can see how backpackers are taken by surprise when a drop bear appears in their orbit.
