On 25 April 1944, "Amycus" got underway for Cape Cretin, New Guinea, where she joined a convoy bound for Hollandia. She reached that base on 3 May, and assumed duty as a repair ship and the flagship of the landing craft control officer. The ship remained in Humboldt Bay through the summer and autumn carrying out repair and tender services for various landing craft. On 20 December, "Amycus" left Hollandia and proceeded to Seeadler Harbor, Manus Island. A week later, she sortied with a task group destined to take part in the Lingayen Gulf landings. As her convoy crossed the South China Sea, there were numerous air raid alerts, but only one attack materialized. On 7 January 1945, two enemy planes came in low to attack. One was shot down by a screening vessel, and the other broke off her approach and escaped undamaged.
