From the early 1800s Aboriginal people have been used as guides and trackers by the police force. This century one of the most highly regarded was Sergeant Alexander Riley of Dubbo, NSW. In 1943 Alexander Riley was awarded the highest police award, the Kings' Medal, for distinguished services. During Tracker Riley's time with the NSW Police Force between 1911 and 1950 he was instrumental in solving several murder cases and finding numerous people lost in the bush. A great many people owe their lives to his exceptional tracking skills. A beautifully made and penetrating film that is a tribute to Tracker Riley, one of the greatest of all Aboriginal trackers as told by his family and descendants.
