Aaron Stuart is a 43-year-old Aboriginal man from the Ngarabunna tribe (renamed the Arabunna tribe for white lips) in South Australia. He is also an author and filmmaker, a former policeman, the chairman of the Arabunna Native Title and a member of the South Australian Aboriginal Advisory Council and South Australian Congress of Indigenous Nations. He now spends his days counselling and saving -- and sometimes failing to save -- the lives of suicidal Aboriginal people.

Stuart is often called to cut down people after they have hanged themselves. "I always administer CPR no matter how long they have been hanging," he says. "I cut down this tribal man in the back shed of a party. The people kept partying and this guy was dead. The police and ambulance took half an hour to arrive. But in fairness they get called a lot for suicide attempts.
