HMAS MELBOURNE, (aircraft carrier), and HMAS VOYAGER, (destroyer), collided in a night exercise off Jervis Bay. VOYAGER sank with a loss of 82 lives. The GC was awarded posthumously to CPO Jonathon Rogers, DSM, for conspicuous bravery in rescue following the collision. The subsequent inquiries and two Royal Commissions into the cause of the collision shook the RAN to its foundations.
