Aussie Angels 9: Operation Wombat

Well, it looks like everything's going wrong for the Angels! There's a new principal at Boyer, who runs the place more like an army than a school; their favourite teacher Ms Lee is on leave and her replacement, Ms Trimbold, obviously doesn't like them. Suddenly Meg and Mike are constantly in trouble. There's no more mobile phones at school, no more time off to help with animal rescues and worst of all they are suspended when Foxie accuses Mike of bringing Feral the ferret to school.
It's Foxie's ferret, of course, but somehow he and Greash have persuaded the new teacher that the Greens are the real school troublemakers!When a baby wombat is dumped in the Greens' driveway, the Angels are sure Greash and Foxie are behind it. There are no wombats in the Otways, so someone must have brought this baby here deliberately. Boris, the reformed former leader of the School Rulers gang, decides to go undercover.
He pretends to be in with Foxie and Greash so the Angels can find out what's going on. When they discover a secret camp in the mountain, they dig up a scam that goes all the way to the top of the new school administration!OPERATION WOMBAT is the ninth instalment in a series loved by children all over Australia.
