As a worker, a theatre producer, an activist, and a businessman, William Onus was a tireless campaigner for the rights of his people in Australia, and a leader for the referendum that saw Australia's Indigenous peoples finally counted as people in their own country.

He was also, perhaps, the first Aboriginal filmmaker.

A new documentary, Ablaze, begins with the discovery of Bill's film in the National Film and Sound Archive and goes on to tell his story, and the story of his fight for equal rights.

Co-director Alec Morgan shares Bill's story and the story of the film.
