Out of the ashes
This is extraordinary, and sweet. I have been out catching koalas in the wild before, which is a stage production of ladders and abseiling and nets, and you would simply never try to handle one with your bare hands (they have the teeth and the claws to do quite an injury - and are simply not the cuddly animals you see in zoos). They also rarely drink free water. For a wild animal to behave like this it must have been in dire straits.
