The Tobruk could transport up to 18 tanks in the tank deck, and more than 40 Armoured Personnel Carriers or Light Armoured Vehicles on the vehicle deck, which had been reinforced to enable the transportation of two Landing Craft Mechanical-8s (LCM-8) on specially designed cradles. In addition, two Landing Craft Vehicular Personnel units could be secured by davits on either side of the superstructure. The ship's roll-on/roll-off function was supplemented by two 8.5 ton cranes and a 70 ton derrick. She had forward and aft helicopter decks, which could be operated simultaneously, and could provide accommodation for up to 520 troops.
Tobruk's final port visit was to Newcastle in June and she returned to to her home port of Sydney for the last time on 25 June. Her final voyage was recognised in Federal Parliament with both the Prime Minister and Opposition Leader acknowledging her service to the nation, noting that she lived up to her motto of 'Faithful and Strong'.
HMAS Tobruk decommissioned on 31 July 2015 after more than three decades of dedicated service. She was subsequently gifted to the Queensland Government for use as a dive wreck. In early December 2016 Tobruk was towed from Sydney to Bundaberg and prepared for scuttling.
On 28 June 2018 she was sunk in the Great Sandy Marine Park, between Bundaberg and Hervey Bay, Queensland.
