Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Malcolm Patch offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Malcolm Patch offers a classic Great Barrier Reef experience, with sprawling coral structures that are home to a good mix of reef fish. We've often seen barracuda schools here, hanging mid-water, and the occasional turtle glides past. It’s a solid choice for divers looking for a relaxed dive with consistent marine life, particularly if you’re keen on exploring the reef's architecture.
Safety Notes
