Harrier Reef
Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Harrier Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Harrier Reef delivers a solid Great Barrier Reef experience. We’ve found decent hard coral formations here, with plenty of small reef fish like damselfish and parrotfish darting between the bommies. It’s a good choice for divers looking for a relaxed, straightforward reef dive, especially if you’re keen on seeing the classic GBR scenery without strong currents. Expect typical visibility for the region, often 15-20 meters.
Safety Notes
Strong currents typical this month (avg 30 cm/s). Good buoyancy control essential.
