Ribbon Number Seven Reef
Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Ribbon Number Seven Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Ribbon Number Seven Reef isn't the blockbuster many expect from the Outer Reefs, but it's a solid, reliable dive if you're exploring the northern sections. We’ve had some pleasant drifts along the reef edge here, often spotting some sizeable pelagics passing through – Black Marlin aren’t unheard of in season. The coral formations themselves are healthy, with good coverage of table and staghorn corals. Keep an eye out for the resident Humpback Groupers and the occasional Spangled Emperor cruising the bommies. It’s a good choice for divers who appreciate a quiet, less crowded site where the marine life feels a bit more natural and unpressured.
