Projects
The Rottnest Ships Graveyard is located in an area to the southwest of Rottnest Island. Since 1910 this area has been used as a place to sink a range of surplus equipment from boats to aeroplanes. There are 47 known vessels that were purposely sunk in the graveyard when they reached the end of their working life. The most recent scuttling was in 1994 when the former HMAS Derwent was sunk in 200m of water.

The majority of these wrecks are yet to be identified due their depths, which range from 58m to 200m of water. The depth makes accessing these wrecks challenging without specialised equipment and training. Jeremy Green and the WA Museum have previously undertaken historical research and maritime archaeological surveys in the Rottnest Ships Graveyard. The intent of the WreckSploration Team is to provide supplementary data to assist with the large body of work already done to date.
The initial research dives on these wrecks were carried out in 2003-2006 by Craig Campbell, Craig Challen, Craig James, Doug Friday, Karl Hall, Mike Caporn and Peter Balalas. Some of their initial work is still available on the Trimix Divers website
The WreckSploration Team is now undertaking a project with support from the WA Museum to go back to the Rottnest Ships Graveyard, and attempt to survey via photogrammetry select wreck sites that hold significant interest and historical value to the WA Museum and community at large.
Although this will not be the first time some of these wrecks have been dived, if successful, this will be the first time many of these wrecks have been positively identified and surveyed with this new technology, enabling 3D models of the wrecks to be seen by the general public.
Ex HMAS Junee
(Graveyard Site 02)
The first of these wrecks to be surveyed was the Ex HMAS Junee, a converted minesweeper that was fitted out for naval training and then scuttled at the end of useful service in 1968 in 83m depth.

The HNLMS K XI
(Graveyard Site 45)
The location of the Dutch submarine HNLMS K XI had been a mystery for decades. Like many scuttled wrecks off the Perth coast, the locations were either incorrectly recorded or never documented. Thanks to a WreckSploration-led team of divers, the location of the HNLMS K XI is no longer a mystery.

County of Caithness
(Graveyard Site 41)
The County of Caithness measured 81.19m in length, 11.82m beam, and 7.19m draft, with a gross tonnage of 1,715 and a net tonnage of 1,636. As a four-masted iron ship, it represented the zenith of sailing ship design during the late 19th century, combining substantial cargo capacity with enhanced stability and speed.

Timaru
(Graveyard Site 42)
During WWI, the Commonwealth Government requisitioned or purchased a number of dredges from around Australia, and between 1917 and 1919 brought them to WA for dredging Cockburn Sound for the construction of the Henderson Naval Base. With the cessation of the war, work stopped and the dredges were laid up in Cockburn Sound, and slowly sold off during the 1920s. One of those was the steam hopper barge 404, aka TIMARU, aka Naval Dredger 4, aka CND4, built in 1893.
