General Sir Peter Cosgrove AK AC (Mil) CVO MC (Retd) is one of Australia's most significant public figures. As a soldier he saw action in Vietnam, winning the Military Cross, and rose to the very top of his profession, becoming Chief of the Defence Force. Soon after his retirement from the Army, he was invited to take charge of the huge relief and rebuilding operation in Queensland after the devastation of Cyclone Larry. In 2014, Cosgrove became Australia's Governor-General. As Governor-General he travelled far and wide, supporting Australians in times of crisis, sadness, joy or celebration, representing us on the world stage with humour, intelligence and a force of personal magnetism that was felt by everyone from prime ministers to presidents. When he retired in July 2019, it was as one of the most beloved and respected governors-general in Australia's history. "You Shouldn't Have Joined..." (an expression much used during his days as a soldier) is the memoir of Cosgrove's extraordinarily full and eventful life, covering some of the military life that featured in his 2006 bestseller, My Story, but in a way that reflects how his perspective has since changed, while also allowing us an incredible insight into the role and world of Australia's Governor-General.
