Ribbon Number Five Reef
Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Ribbon Number Five Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Ribbon Number Five Reef is one of those spots that sticks with you long after the last dive. We always suggest trying to hit this one early in the morning, before the liveaboards start shuffling around. The light penetration through the shallower sections of the reef, especially around the big bommies of yellow scroll coral, is just fantastic, casting dappled patterns on the sand. We love dropping in here and drifting along the wall, keeping an eye out for the bigger pelagics that cruise by. Black marlin have made an appearance on more than one occasion for us, a real heart-stopper. But it's not just the big stuff; the sheer density of the stony corals and staghorn formations is incredible. You'll find yourself slowly finning over fields of it, spotting tiny wrasse darting between the branches and maybe a sleepy longface emperor tucked into a crevice. It’s a great site for divers who appreciate intricate coral topography and a chance at some exciting open-water encounters.
