Fremantle began east-coast escort duty in April 1943, following a month in which Japanese submarines had sunk seven ships in coastal waters. She moved to Darwin in August and spent twenty-one months protecting northern routes before taking up guard and escort work around New Guinea. Postwar duties included mine clearance in Chinese waters, national-service training, fisheries protection, survey work, and general fleet service. Her largely uneventful convoy record illustrates the value of an escort's presence: protected shipping gave attackers a reason to seek easier targets elsewhere.
