A Waltz Through the Hills (1988)

"Two orphans want to go home. But home is halfway around the world"

When Sammy Dean and her older brother Andy are suddenly orphaned, they fear that they will be separated and placed in foster homes. So they set off along on foot, hoping to reach a ship that will take them to England and their only surviving relatives. The two young runaways must make their dangerous journey through some of the world’s harshest terrain-the wilds of the Australian outback.
