Why dive here
With 73+ marine species recorded in the area - including dugongs, great white sharks, humpback whales and sperm whales - La Diéppoise, wreck offers some of Prony Bay's richest wreck diving. Water ranges 22-27°C, warmest January, February, March.
We love the La Diéppoise. It’s a shipwreck with a difference. This anti-mine vessel, later repurposed as a lighthouse and beacon ship, had a wooden hull – a detail that now makes it incredibly unique. When you drop down to 23m, you’ll find that the wood has long since vanished, leaving behind just the skeletal ribs of the hull. It’s like diving through a ghost ship, a fascinating lattice that lets the light stream through and gives you an unobstructed view into its former compartments. You can easily swim right through the remaining structure, a genuinely eerie experience as you trace the ship’s original form. While fixed growth on the wreck itself is minimal, the structure acts as an artificial reef, drawing in big schools of bannerfish and wrasse that flutter around the ribs. Keep an eye out for speckled grouper lurking in the shadows and the occasional reef manta ray cruising past in the deeper water. It's a mellow dive, perfect for wreck enthusiasts who appreciate a bit of history and a different kind of exploration.
