Keith Hetherington (1929 - June 30, 2021) was an Australian actor, writer and novelist who worked as television scriptwriter on such Australian TV shows as Homicide, Matlock Police, Division 4, Solo One, The Box, The Spoiler and Chopper Squad. Hetherington began writing particularly westerns for Cleveland to pen about 1,000 novels under the names Kirk Hamilton and Brett Waring. Hetherington became a journalist for the Queensland Health Education Council, writing weekly articles for newspapers and radio plays dramatising on health subjects. A former colleague invited Hetherington to work for Crawford Productions around 1970. After initially writing television scripts in his home town of Brisbane, he moved to Victoria in 1971 as freelancer on shows. When Australian television production declined in 1975, Hetherington returned writing Cleveland westerns, with some television work. He also wrote a book on metal detecting, some film tie-in novels, and thrillers A Dragon out of the South and The Judas Coast.
