Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Helix Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Helix Reef offers a solid Great Barrier Reef experience, classic coral bommies and fringing reef. You’ll drift past plenty of anemones with their resident clownfish, along with parrotfish and fusiliers in the shallows. It's a relaxed dive, good for newer divers or anyone looking for a straightforward, pleasant afternoon underwater. We’d suggest keeping an eye out for green turtles, they often cruise through the channels here.
