It serves as a significant feature of the reef topography and a natural sanctuary for marine life.
The site is renowned for its diverse marine inhabitants, particularly during the winter months when it provides crucial shelter for majestic grey nurse sharks. Divers can also encounter impressively large moray eels, various species of wobbegongs, and impressive schools of large pelagic fish that frequent the area.
The best time to visit Julian Rocks - Cod Hole for an encounter with grey nurse sharks is during the winter season. This advanced dive site is best suited for experienced divers comfortable with cave or cavern environments and potential currents.
