In the 1970s, Robert Trimbole and the Calabrian Mafia ruled Australia's marijuana trade from their castles in Griffith, NSW. The business expanded to heroin when Trimbole joined Terry Clark and the notorious Mr Asia syndicate, and then to murder when anti-drugs campaigner Donald Mackay blew the whistle. Walkley Award-winning journalist Keith Moor learned the truth about Mackay's disappearance from those involved. His classic account now includes excerpts from the unpublished memoir of Mackay's widow and a dossier on the involvement of controversial federal minister Al Grassby. Moor asks why 'Aussie Bob' Trimbole was allowed to flee the country and was never brought back to face his crimes. He also questions how Trimbole's Griffith Mafia bosses are today able to maintain their links with the global drug trade.
