Don't Blame the Koalas

In England a recently bereaved widow and her two children discover that they've inherited a property in Australia. With some reluctance they head to Australia to claim their inheritance only to discover that the profitable sheep station they've imagined is in fact a rather out of the way wildlife park full of Australian native animals. What's more it has human occupants as well - a distantly related trio of grandchildren who have been bequeathed lifelong rights to live on the property. As well, there's an Australian born Vietnamese animal handler who's somehow the only one who has real expertise in dealing with native Australian animals.
