Dive into Our Latest Reef Project
Building a Sustainable Future Beneath the Waves
Join us as we embark on an exciting journey to create two thriving artificial reefs, enhancing marine biodiversity and supporting recreational fishing in South Australia.
Project Milestones
Reef Build Update
The recreational fishing and resilience reef builds at Wirrina Cove and Nepean Bay are now complete. Working alongside In-Depth Innovations and McMahons Services, detailed site surveys and underwater assessments using ROV technology helped identify ideal locations for the reef installations. After months of planning, preparation and construction, the reef modules have now been successfully deployed. These new reef systems will provide valuable habitat for marine life, support ecosystem recovery, and create exciting opportunities for South Australian recreational fishers for years to come.

Wirrina Site Survey
On the 5th of March 2026, Will joined McMahons Services and In-Depth Innovations offshore from Wirrina Cove to complete a detailed ROV survey for the future artificial reef build, assessing the seabed and surrounding habitat to confirm the site’s suitability for deployment. With perfect glassy conditions and a promising mix of rubble and muddy bottom in 27 metres of water, the successful survey marked another exciting step toward bringing the artificial reef project to life.
