The depot was renamed HMAS "Penguin IV" with the outbreak of the Second World War. On 1 August 1940, the depot was commissioned as HMAS "Melville". The Naval Wireless Transmitting Station Coonawarra, which operated under the command of "Melville", provided essential communications in support of the Allied operations in the Dutch East Indies and South West Pacific Area regions. The base was subjected to numerous bombing raids during the "Battle of Darwin" and suffered significant damage. After the cessation of hostilities, the base was hampered by the continuing expansion of Darwin and the increase in numbers  of naval personnel. It was decided to move the operations to the Naval Wireless Transmitting Station Coonawarra, which was commissioned on 16 March 1970 as HMAS "Coonawarra". "Melville" continued to remain in use until it was destroyed by Cyclone Tracy on 25 December 1974.
