I'm trying to find out the name of this book I read in High School and it's driving me mad!

The book was set in Sydney, Australia and all the animal escaped from the Toronga zoo, I think there was a war, and all the characters where children. If anyone can help me out with this book id be, well relieved. :o

Thanks
