Illustrated by Laura Hurwitz.
Riley, Cousin Alice, Aunt Martha and Uncle Max visit the Australian outback where they research the local koala population, which has scattered and shrunk due to increased drought, bush fires and farming in the outback.
While staying at a working sheep station, they see kangaroos, a platypus, Uluru and much more. Riley becomes an official jackaroo and helps save the sheep from a wild dingo, but can he find a way to save the koalas and the outback?
