Perth II HMAS (35757)
500m SW from Seal Island, King George Sound

HMAS Perth II was a 4,850 tonnes, 133 metre long Charles F. Adams (Modified Perth) class guided missile destroyer built in Michigan, USA. It was the Royal Australian Navy’s only vessel to have been hit by enemy fire in the last 50 years, while assigned to the US Seventh Fleet in Vietnam between 1967-69. The US Secretary of Navy awarded HMAS Perth with two citations for ‘Meritorious Service’ and ‘Exceptionally Meritorious Service’. In 1981-82 HMAS Perth II patrolled the Western Arabian Sea with the USS Ranger and USS John F. Kennedy battle groups during the Iran-Iraq War, and undertook numerous other missions and diplomatic visits as Australia’s senior naval unit, steaming over a million nautical miles throughout the world.
After a distinguished 34 year career HMAS Perth II was decommissioned in 1999, and on 24 November 2001 was scuttled in 38m depth off Seal Island, King George Sound to become a recreational dive site.
HMAS Perth II is now enjoying a revival as a premier dive tourism attraction in the state’s Southwest, along with HMAS Swan scuttled in 1998 off Dunsborough.
The WA Museum’s underwater archaeologists and conservators monitor the HMAS Perth II and HMAS Swan wrecks, to record information about site formation and corrosion processes on historic iron and steel shipwrecks.
