Between March and May 1974, the landing craft was based in Singapore, and was used to transport military materiel and stores to and from Belawan, Indonesia. Several major exercises were participated in during the rest of 1974: Kangaroo One in June, and Kentia Palm in September. During October and November, "Labuan" was stationed on the Great Barrier Reef with clearance divers embarked, as part of a project tracking the spread of the Crown of Thorns starfish. "Labuan" was the only RAN "Balikpapan"-class ship not involved in Operation Navy Help Darwin (the RAN response following Cyclone Tracy's destruction of Darwin in December 1974), as she was undergoing refit at the time. In late February 1975, "Labuan" collided with a lighter during Exercise Wagon Train II. The damage was limited to patching a hole above the waterline. During April and May, the landing craft operated in southern Australian waters in support of Army training exercises. "Labuan" returned to Sydney, and during 12 and 13 May transported the RAN's first two Sea King helicopters to Jervis Bay. The rest of 1975 and most of 1976 was spent on training exercises.
