Walkabout

In November, a white, city-bred teenaged schoolgirl and her much-younger brother become stranded in the wilderness after their father goes berserk. After driving them far into the Australian outback, ostensibly for a picnic, the father suddenly begins shooting at the children. They run behind rocks for cover, whereupon he sets the car on fire and suicide. The girl conceals what has happened from her brother and, after grabbing some food and supplies, the pair head out into the desert.
