Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Split Bommie, Hastings Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Split Bommie at Hastings Reef is one of those sites we always recommend for a relaxed afternoon. The name makes sense once you’re down there – it's a collection of distinct coral heads, or bommies, that sit a little way off the main reef, creating these lovely channels and swim-throughs. At a maximum depth of 13 metres, it’s a brilliant spot for newer divers or anyone just wanting to spend some quality time soaking in the details without worrying about deco. We love the easygoing feel here. You'll drift over big tables of stony coral, their surfaces textured like ancient landscapes, and spot the brilliant fluorescence grass coral glowing subtly in the shadows. Look closely for Giant morays peeking out from their crevices, and keep an eye on the sand patches for Green turtles munching on seagrass. On a sunny day, the light plays beautifully through the shallow water, illuminating schools of Bicolour Parrotfish and Blue-lined Surgeonfish grazing the reef. It’s a gentle, pretty dive, perfect for photographers or just unwinding.
