Rolf De Heer's earlier movie "Tracker"..with David Gulpilil (the Narrator in Ten Canoes) as the tracker........is one you should put on your "To see" list http://www.imdb.com/title/tt0212132/

This from one of the reviews sums it up nicely. "A grim topic, a past that shames every Australian to this day, except of course for those like our beloved PM whose compassion chip has been surgically removed."
