Moresby was launched at the State Dockyard, Newcastle on 7 September 1963 by the wife of Rear Admiral Gatacre.

Throughout her career in the RAN, Moresby sailed over 1 million miles, and carried out surveys of Torres Strait, the D'Entrecasteaux Channel in Tasmania, Exmouth Gulf, Wilsons Promontory and the Gulf of Papua.

[4] She was renamed MV Patricia Anne Hotung,[5] and underwent a A$1 million refit at Maritime Engineers in Fremantle, Western Australia, enabling the 95-metre (312 ft) ship to carry 500 passengers and 2,021 tons of cargo.

IOM Director General Brunson McKinley described the ship's role as "invaluable" and "a remarkable contribution to the international humanitarian effort to bring East Timorese refugees home to begin rebuilding their devastated country"[7]
