In “Walkabout,” the crucial detail is that the two teenagers can never find a way to communicate, not even by using sign language. Partly this is because the girl feels no need to do so: Throughout the film she remains implacably middle-class and conventional, and she regards the aborigine as more of a curiosity and convenience than a fellow spirit. Because not enough information is given, we cannot attribute her attitude to racism or cultural bias, but certainly it reveals a vast lack of curiosity. And the aborigine, for his part, lacks the imagination to press his case—his sexual desires—in any terms other than the rituals of his people. When that fails, he is finished, and in despair
 The movie is not the heartwarming story of how the girl and her brother are lost in the outback and survive because of the knowledge of the resourceful aborigine. It is about how all three are still lost at the end of the film—more lost than before, because now they are lost inside themselves instead of merely adrift in the world.
