An Australian girl gets lost in the Outback, but she's befriended by a kangaroo who gives her a ride in her pouch as they search for the girl's home. Aiding the pair are musically gifted koalas, platypuses, and kookaburras in this film based on Ethel Pedley's 1899 children's book, with animated humans and animals superimposed upon a live-action background.

In the Australian Outback, the Carmody family--Paddy, Ida, and their teenage son Sean--are sheep drovers, always on the move. Ida and Sean want to settle down and buy a farm. Paddy wants to keep moving. A sheep-shearing contest, the birth of a child, drinking, gambling, and a racehorse will all have a part in the final decision.

In 1964, atomic war wipes out humanity in the northern hemisphere; one American submarine finds temporary safe haven in Australia, where life-as-usual covers growing despair. In denial about the loss of his wife and children in the holocaust, American Captain Towers meets careworn but gorgeous Moira Davidson, who begins to fall for him. The sub returns after reconnaissance a month (or less) before the end; will Towers and Moira find comfort with each other?
