Why dive here
With 199+ marine species recorded in the area - including blue sharks, bull sharks, dolphins, dugongs and great white sharks - Julian Rocks offers some of Sydney & New South Wales's richest wreck diving. Water ranges 18-23°C, warmest January, February, March.
Julian Rocks is our favourite kind of dive site: utterly chaotic, in the best possible way. The mixing of currents here really does deliver, not just in the sheer number of species, but in the delightful combinations you’ll often find. We’ve seen everything from schooling wobbegongs tucked into the rocky overhangs to manta rays cruising through the blue, all in a single dive. It's a place where you keep your head on a swivel, because a blotcheye soldierfish might be staring you down from a crack while a gang of dusky filefish materialises out of the haze. We often find the spitlure frogfish here, camouflaged perfectly against the sponges, and the leopard sharks are practically a guarantee in summer. Julian Rocks is best suited for divers who appreciate dynamic environments and aren't afraid of a bit of current, which can pick up quickly. Our tip: go early to beat the crowds, and always ask the skipper about the specific conditions that morning – they know the sweet spots.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
Julian Rocks Wreck History
Vessel Type
barge
Cause
unknown
Located in the clear, protected waters of the Frioul archipelago near Marseille, the Barge de Tiboulen du Frioul is a fantastic example of how even the most modest vessel can become a thriving underwater ecosystem. Situated near the small island of Tiboulen, a well-known local diving area, this barge sank under unknown circumstances and now serves as a popular and accessible dive site. Its simple, open structure makes it a safe and enjoyable wreck to explore, perfect for newly certified wreck divers or those looking for a relaxing dive. The structure is often covered in colourful sponges and algae, providing shelter for scorpionfish, blennies, and the occasional conger eel, making it a microcosm of the rich marine life found within France's Calanques National Park.
