Koalas do exist outside parks and zoos. Late last year Himself and I holidayed at Port Macquarie (NSW mid north coast) where koalas are quite active - relatively speaking, because they don't do much at all! The camp ground where we stayed had several resident koalas, definitely not tame. A large tree just near our caravan was a favoured spot; late in the afternoon a koala would appear to take up residence for the night. We also heard them growling at night - males warning other males to keep away, and also telling the girls "I'm much more fantastic that he is, come and mate with me".
