Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Iris Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Iris Reef offers a classic Outer Reef experience, with sprawling coral formations that undulate gently in the current. We’ve seen plenty of reef sharks cruising the edges here, and the bommies often hide schools of snapper. It’s a solid choice for a multi-dive day, especially if you’re looking for those reliable Great Barrier Reef sights.
