Tasman was built for the Singapore, Java and Australian east coast trade and was on the Australian route until 1928 when the new twin screw turbinesteamers Nieuw Holland and Nieuw Zeeland took over the route. Tasman served the Java–South Africa route until transferred to the South Pacific New Zealand-Sydney service.
At the outbreak of hostilities between Japan and China in 1937, Tasman was docked at the city of Shanghai during the bombing of Shanghai, but escaped undamaged.
On the outbreak of war in the Pacific, December 1941 the ship was in the Timor Sea from which she was sent to Singapore. On 1 January 1942 she evacuated civilians and elements of the Royal Air Force. Arriving in Surabaya the RAF personnel were left and more civilian evacuees were loaded for Australia.
Tasman was one of the 21 KPM ships that sought refuge in Australia on the fall of Java that the Commanding General, United States Army Forces in Australia (USAFIA) was instructed to purchase or charter for an SWPA local fleet. On 26 March 1942 the Chief Quartermaster, USAFIA arranged interim charters pending final negotiations with the Netherlands Government in London. Final negotiations between the War Shipping Administration (WSA) and the Dutch government resulted in their being placed under U.S. Army control through a complex charter arrangement in which the British Ministry War Transport (BMWT) chartered the KPM vessels and with WSA allocated them to SWPA with the stipulation they be under total control of the U.S. Army. Though some sources note the arrangement was through the Allied Consultative Shipping Council (ACSC), Masterson details the command's objection and rejection of ships intended for critical military operations being arranged by that means. General MacArthur reported on 28 April that his fleet of 28 vessels included the 21 KPM ships. Tasman was given the local fleet number X-16.[2]
The ship was converted at Sydney to carry troops. She transported both Australian and American troops to Port Moresby, Milne Bay and Oro Bay in New Guinea. On 11 July 1942 she had arrived at Milne Bay with Brigadier John Field and the 7th Brigade Group as "Milne Force" to protect the developing port and airfields. She was in Milne Bay the night before and left the morning of the Japanese landings and the first ship to reinforce Milne Bay during the Japanese attempt to take the airfields there. Tasman made three later attempts to enter the bay, being driven off by Japanese naval vessels. The ship was escorted by during these New Guinea operations.
In February 1943 SWPA notified the War Department that it was converting the ship to a hospital ship for intra-theater use, requesting it be certified under the Hague Convention. Though under the control of the U.S. Army, the ship, along with the other KPM hospital ship conversion Maetsuycker, was under "Dutch registry and certified under the Hague Convention by the Netherlands Government" and flew the Dutch flag. The conversion, with plans provided by Army engineers, was done during four months at Melbourne
She was equipped to carry 250 patients and continued to be crewed by Dutch officers and Javanese (Indonesian) sailors. The hospital was staffed by American doctors and nurses. She served in the South West Pacific area and, as was Maetsuycker, limited to transporting patients between bases in SWPA. Tasman was at the vanguard throughout the Pacific campaign and transported repatriated prisoners of war from the Japanese prison camps at Santo Tomas, Philippines.
In June 1945 Tasman entered Sydney for refit before being released from SWPA charter and returned to BMWT control in July. By October the ship was caught up in the turmoil of both Indonesian independence and Australian labor union activities with Indonesian seamen walking off, Australia declaring such non-European seamen illegal immigrants, labor listing the ship as "black" in sympathy with the Indonesian seamen and refusing any work related to the ship with a "scab crew" with charges and counter charges of "Communism" among labor leaders.
Tasman was returned to the Dutch Government in December 1945 still under the command of Captain Willem Eleveld, who had commanded the ship from 1941 through the war. He described her as "lucky" as she had never been bombed despite constant operations.
After the end of World War II, she was returned to her owners KPM on 1 July 1947. Later she was transferred to Koninklijke Java-China Paketvaart Lijnen in 1948 before being transferred back to KPM in 1955. She was sold and broken up for scrap in Hong Kong in 1958.[1]
