context_page_description: Rockingham Naval Memorial Park is a military memorial in the City of Rockingham, Western Australia, dedicated to the Royal Australian Navy. It contains a number of commemorative plaques, a 110 mm gun turret from HMAS Derwent and a submarine fin from HMAS Orion.
  The memorial was dedicated on 24 January 1996 by the mayor of the City Of Rockingham, F. W. Gardiner. The project was jointly-funded by the City of Rockingham, the Federal Government of Australia, the State Government of Western Australia and the Naval Association of Australia.
  Apart from the Rockingham Naval Memorial Park, two other major war memorials exist in Rockingham, the Rockingham War Memorial and the Z Special Unit Memorial, in honour of the Z Special Unit.
context_section_description: HMAS Orion (S 61) was one of six Oberon-class submarines of the Royal Australian Navy. Orion was in service from 1977 to 1996. The submarine was eventually broken up for scrap in 2006. The fin of the Orion was placed in the Naval Memorial Park, while the port propeller was donated to the Western Australia Maritime Museum.
  On 3 August 2017, a commemoration of the 30th anniversary of the loss of Able Seaman Hugh Marcrow and Seaman Damien Humphreys from HMAS Otama was held at the memorial. Markcrow and Humphreys were lost when the submarine Otama dived off the New South Wales coast on 3 August 1987; their bodies were never recovered.
  An inaugural Australian Lost Submariners Memorial Service was held by The Submarines Association of Australia in August 2019 at the Orion fin, attended by more than 200 current and former submariners. The event commemorated the submariners who lost their lives since the establishment of the modern Australian Submarine Force in 1967.
