'The Aboriginal tracker is a stock character in certain Australian films, employed as set dressing, catalyst, curio. Although fictional trackers have been celebrated on celluloid, few real trackers have been given life within the national memory. Some people may recall Billy Dargin and his role in locating and shooting Ben Hall. Others might think of Dubbo’s Tracker Riley, or Dick-a-Dick, who found the missing Cooper and Duff children near Natimuk in 1864 when they had been given up for dead.' (Introduction)
