HMAS Whang Pu was used as an accommodation ship, a mobile repair ship, a base works ship and fulfilled numerous other roles. Understandably, the ship was referred to as a ‘jack of all trades’
On 6 July 1944 Whang Pu departed Milne Bay and headed to Madang, via Finschhafen, arriving there on the 9th. It was now utilised as a base works ship for the construction of the base facilities at Madang, as well as continuing to provide repair facilities for frigates, corvettes and motor launches. Logistics and medical support continued with Whang Pu supporting over 2000 RAN personnel ashore or in smaller vessels. In April-May 1945 Whang Pu was converted to a Naval Stores Issue Ship but remained the ‘Jack of all trades’ for maintenance and administrative support.
On 10 June 1945 Whang Pu departed Madang and headed westward to its final tasking at the island of Morotai, in the Netherlands East Indies. Morotai had been captured in September 1944 by US troops and was used as a forward air and naval base by Allied units. Australian forces were also based on the island in preparation for the landings on Borneo in 1945. Isolated parts of the island were still held by the Japanese but they were contained and rarely seen.
Whang Pu arrived at Morotai on 16 June and was moored in the harbour and commenced work as a stores issuing ship and floating workshop for smaller vessels—it was not to move for its berth for the next 9 months. The ship suffered its only death on 20 June 1945 when Steward William Fisher died while returning from leave ashore. He slipped when boarding the ship, struck his head and subsequently drowned. He was buried in the war cemetery at Morotai but was later re-interred at Ambon War Cemetery, Indonesia.
Whang Pu was at Morotai when the Japanese surrender was accepted there by General Thomas Blamey on 9 September 1945. It finally departed the island on 16 February 1946, with a steaming crew and stores personnel only on board. It sailed north, via Subic Bay, to Hong Kong where it arrived on 26 February.
After being de-stored it was decommissioned on 22 April 1946 and its remaining ships company returned to Australia in the frigate HMAS Murchison. Whang Pu was then returned to its owners.
Whang Pu was sold in November 1949 and broken up.
