Animal Haven is a temporary home for all sorts of Australian wildlife, although there are a few permanent residents as well, like Oscar the owl, Fur Bag the possum, Cinnamon the koala and Alice the labrador. Meg and Mike live there, too, and they work so hard to help their parents rescue and look after the animals that the locals at Jeff's Creek have nicknamed them the Aussie Angels. Their little brother Mark is more of an Aussie devil, though, and sometimes makes their job difficult with his mischievous tricks. Then there's Boris Boola and his gang . . .
In their first adventure, the koalas are in trouble, they need rescuing and the Aussie Angels are just the ones for the job.
