Detroit 6–71 diesel motors, providing 675 brake horsepower to the two propeller shafts, allowing the vessels to reach 9 knots (17 km/h; 10 mph).

[2] The LCHs have a maximum payload of 180 tons; equivalent to 3 Leopard 1 tanks, 13 M113 armoured personnel carriers 23 quarter-tonne trucks, or four LARC-V amphibious cargo vehicles.

[2] The flat, box-like keel causes the ships to roll considerably in other-than-calm conditions, limiting their ability to make long voyages.

[5] After completing working-up exercises, in May 1973, Labuan transported Clearance Diving Team One (CDT1) to Moreton Island to destroy a World War II era torpedo.

[5] Between 15 August and 12 October, the landing craft visited communities around Papua New Guinea, with the clearance divers clearing reef passages and disposing of unexploded ordnance from World War II.

[5] On 19 October, the vessel left Papua New Guinea and sailed to Cairns with sister ship HMAS Brunei.

[5] 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.

[5][9] In RNVR service, Labuan was used to provide training and seagoing experience to Reserve personnel, generally on two-week deployments.

[5] During September and October 1980, clearance divers were embarked aboard Labuan for three weeks of shipping channel clearing around the Solomon Islands.

[6][clarification needed] At the start of 1992, the final RANR training cruise occurred, after which the vessel was docked in Cairns for a refit.

[5] On 14 May 1996, while returning from Exercise Thunder Bay 96, the landing craft ran aground on a reef off South Harrison Island.

[5] In March 1997, the ship was placed on standby to evacuate Australian citizens from political unrest in Papua New Guinea; this need did not eventuate, and Labuan resumed normal operations in early April.

[5] In March 2006, Labuan was involved in humanitarian operations following Cyclone Larry (after having ridden out the storm herself in Wahday Creek), moving supplies and equipment from Townsville to Mourilyan.

[5] From April until June 2009, Labuan and Tarakan were deployed to the southwest Pacific, visiting Vanuatu, Tonga, and Western Samoa.

[5] In July 2010, the ship was involved in the US Navy's Pacific Partnership humanitarian assistance operation, providing over-the-shore support and acting as a forward base for medical and dental personnel during visits to Indonesia and Timor Leste.

[6] After participating in Exercise Croix Du Sud off New Caledonia, Labuan and Tarakan delivered humanitarian supplies to remote coastal settlements in the Solomon Islands in September 2014 as part of Australian support efforts in the region.

[17] In 2013, the Australian government had promised to gift one of the Balikpapan-class vessels due to leave RAN service to Papua New Guinea.

[18] As part of Australia's assistance to the Papua New Guinea Defence Force, the Royal Australian Navy provides her commanding officer and a chief of the boat.
