Bob Maza (1939-2000), actor, playwright and activist, was born on Palm Island in North Queensland. His father was from Murray Island in the Torres Strait, his mother of the Yidinjdji people. After the 1967 referendum he became active in Aboriginal affairs. In 1970 he travelled to the US as part of a delegation to the United Nations, and spent time working with the National Black Theatre of Harlem. On his return to Australia he co-founded the National Black Theatre of Australia, and began to work as a playwright. His best-known play, The Keepers, was performed at the Adelaide Festival and Belvoir Street Theatre in 1988, and earned him that year's National Black Playwright Award. His other plays include No Shame and the radio drama Sugarbag. As an actor he had a regular role on ABC TV's Bellbird during the 1970s. His work in film included roles in The Chant of Jimmy Blacksmith (1978), The Fringe Dwellers (1985) and Ground Zero (1987). He won the Order of Australia in 1993 and the Red Ochre Award, for outstanding contribution to the arts, in 1988.
