Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Hastings Reef Blue Lagoon offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Blue Lagoon at Hastings Reef is a proper shallow dive, maxing out around 13 metres. What we really love here is the sheer density of small stuff. It’s not about huge pelagics or dramatic walls, though there is a nice wall feature that drops away from the shallows. Our favourite part has to be the sandy patches, absolutely riddled with sea cucumbers, including leopard and pineapple varieties, just doing their thing. Keep your eyes peeled low, near the sand, and along the coral. We've seen some fantastic decorator crabs camouflaging themselves perfectly, and the nudibranchs are often out and about if you take your time. You’ll spot schools of Yellow Spotted Trevally cruising by, and the cauliflower corals are particularly vibrant. It’s also a solid spot for sunburst and racoon butterflyfish. This site really suits divers who enjoy a slower pace, hunting for the smaller, more elusive creatures. If you’re into macro photography, or just like finding weird and wonderful things tucked into crevices, this is your kind of place.
