Historic MV Andrew Wilson to Become South Australia’s Newest Artificial Reef and Dive Site

A historic working vessel is preparing for a new chapter beneath the waves, with the MV Andrew Wilson set to become South Australia’s newest artificial reef and recreational dive site.

The retired dredging vessel will be deliberately scuttled around six kilometres offshore from Brighton Beach, where it will rest in approximately 20 metres of water. Once on the seabed, the ship is expected to provide a permanent habitat for marine life while creating a new attraction for recreational divers and anglers.

The project comes as South Australia continues efforts to support the recovery of marine ecosystems affected by the state’s prolonged harmful algal bloom, which has had a significant impact on coastal habitats and marine wildlife.

A New Purpose for a Historic Vessel

Rather than being scrapped, the 40-metre MV Andrew Wilson has been donated for use as an artificial reef.

Before being sunk, the vessel will undergo extensive preparation to remove fuels, oils and any potentially hazardous materials, ensuring it meets environmental standards for reef creation.

Once submerged, the structure will provide hard surfaces for algae, corals, sponges and other marine organisms to colonise. Over time, these communities are expected to attract fish and other marine species, transforming the former workboat into a thriving underwater ecosystem.

Artificial reefs created from purpose-prepared ships have proven successful worldwide, often developing into productive marine habitats while providing popular dive sites.

Supporting Marine Recovery

The new reef forms part of wider efforts to enhance marine habitats following South Australia’s ongoing algal bloom, which has caused widespread impacts across the state’s coastline.

Although an artificial reef cannot replace damaged natural ecosystems, it can provide additional habitat for marine species and increase local biodiversity by creating new shelter and feeding opportunities.

The Brighton location is also expected to become a valuable destination for recreational diving, offering divers an accessible wreck that will evolve as marine life establishes itself over the coming years.

Growing Australia’s Artificial Reef Network

Australia has successfully created numerous artificial reefs using retired vessels, many of which have become thriving marine habitats and significant tourism attractions.

Once the MV Andrew Wilson is scuttled, it is expected to join that growing network, offering opportunities for divers, underwater photographers, marine researchers and recreational fishers alike while giving a historic vessel a lasting legacy beneath the sea.
