minehunters and a month previous, the efforts of Melville confirmed that the shipwreck was not the hospital ship. In March 2017, Melville was sent to North Queensland after tropical cyclone Debbie. Its task was to assist in humanitarian operations consisting of clean up, community assistance and to provide basic provisions such as food and water. In August 2017, Melville was deployed to Shoalwater Bay, approximately 30 kilometres off the coast of Queensland, tasked with assisting the search for a crashed United States Marine Corps MV-22 Osprey tilt-rotor aircraft. A Royal Australian Navy clearance diving team was also utilised to search the wreck for three missing members of the aircrew and United States marines from the III Marine Expeditionary Force (III MEF), and to assist in the US led operation to recover the aircraft. On 29 January 2018, HMAS Melville was awarded a Meritorious Unit Commendation by the United States Marine Corps.
