Barrett was born in Bondi, Australia, the son of George and Marguerite Barrett. He left school at 14 to do a few odd jobs before taking on a trade as a butcher around the eastern suburbs of Sydney. He gave up his trade when a hind of beef fell on him and injured his shoulder. While he was on worker's compensation, he completed three writing courses at the WEA (Workers' Educational Association). When his sickness benefits ran out he worked in various jobs, DJ, barman, or went on the dole. His first writing job was gag writing for disc jockeys on Radio 2SM. He also signed on with a casting agent and started acting in commercials and television series and appeared in what he says are 'two classic A-grade clunkers'; the movies Bullamakanka and The Empty Beach.
Robert G. Barrett's books have sold over one million copies, earning him the crown of king of Australia's popular fiction. This new novel, featuring his much-loved hero Les Norton, is a cracking story featuring the legendary witch of old Kings Cross, Rosaleen Norton, and a modern-day hunt through Victoria. Hold onto your hats for a rip-roaring read full of all the action, sex and humour that is the Robert G. Barrett trademark. 2003 marks a very special anniversary for the former butcher from Bondi, with the publication of his 20th book.
