HMAS Brisbane (D 41) was one of three Perth-class guided missile destroyers to serve in the Royal Australian Navy (RAN).

[2] During the mid-1960s, the United States government pressured Australia to increase the resources it was committing to the Vietnam War; one of the requests was for a combat vessel to help the USN meet the demand for naval gunfire support operations.

[8] Australia was the only allied nation to provide naval support to the United States Navy during the Vietnam War.

[21] After time in Australian waters to prepare for wartime service, Brisbane arrived in Subic on 28 March 1969 to be deployed to the Vietnam War.

[2][22] Responsibility was handed over from Perth on 31 March, and the ship spent the first two weeks of April undergoing familiarisation exercises and having both gun turrets repaired following equipment failures early on.

[22] The destroyer was first deployed to naval gunfire support duties, and arrived off the IV Corps operating area on 15 April.

[22] During this period, there was a surge in Market Time activity, and although Brisbane was not assigned to that operation, she was asked to provide gunfire assistance on several occasions.

[23] On 5 May, Brisbane was ordered to the Gulf of Thailand to provide support for South Vietnamese forces operating near the Cambodian border.

[25] On 10 June, the Australian ship relieved USS Rupertus and commenced gunline duties in the II Corps Area.

[29] The ships were deployed to Yankee Station, with Brisbane and USS Perkins (plus other destroyers on occasion) performing escort and plane guard duties.

[29] On 14 September, Brisbane sailed to Subic for maintenance and fitting of the replacement turret, then departed on 1 October for Sydney, having been relieved by the Daring-class destroyer HMAS Vendetta two days earlier.

[31] This, combined with the damage to the forward gun turret and other defects, meant that the destroyer only fired 7,891 shells during the six-month deployment.

[31] Two officers from the ship were Mentioned in Despatches, while other personnel awards included a British Empire Medal and 25 Naval Board commendations.

[34] Brisbane returned to carrier escort duties, where she remained until sailing to Hong Kong for maintenance on 12 June.

[34] Foul weather prevented gunfire support operations until 30 June, but the rate of activity increased, with 60 fire missions completed by the end of the three-week period.

[34] In mid-July, after a short stint back in Region 3, Brisbane sailed to Subic for maintenance and leave.

[2][43] In addition to facilitating communications, Brisbane's personnel were responsible for clearing sites for helicopters and headquarters, salvaging boats and equipment, repairs of infrastructure, and installation of power generators: on average, 160 of the ship's company went ashore each day.

[2] In April 1977, Brisbane and HMNZS Canterbury were assigned to escort Melbourne during a five-month return trip to the United Kingdom for the Silver Jubilee Naval Review.

[44] On 9 May, one of the carrier's Sea King helicopters was forced to ditch in the Indian Ocean: Brisbane successfully recovered the aircrew.

[45] The ships participated in the naval review at Spithead on 28 June, and Brisbane returned to Sydney on 4 October, entering dock for refit eight days later.

[1] In early 1988, Brisbane visited Melbourne for the Moomba festal, then sailed to her namesake city in August to participate in a 'Shopwindow' exercise with ships of the Royal New Zealand Navy.

[1] Brisbane attended RIMPAC during April and May 1990, then returned to Australia to prepare for deployment to the Persian Gulf as part of Operation Damask.

[1] In March 2000, Brisbane was one of three RAN ships to participate in a Royal New Zealand Navy fleet concentration period.

[51] Her bridge and one of her 5-inch (127 mm) guns were removed and preserved at the Australian War Memorial in Canberra, which were incorporated into the post-1945 galleries, which opened in 2007.

[57] As part of celebrations for the tenth anniversary of Brisbane's scuttling, 92.7 MIX FM conducted the world's first live underwater radio broadcast from the wreck on 31 July 2015.
