Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Down Under Diving offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Down Under Diving is one of those spots on the GBR that really embodies the phrase "living reef." We love it for its sheer density of fish life, particularly the schools of Humphead Unicornfish that seem to flow over the reef like a shimmering river. On a good day, the visibility can be excellent, letting you watch the Redstripe Tuskfish dig through the sand or the Blacksaddled Coral Groupers eye their next meal. Our favourite dives here are the morning ones; the light catches the Staghorn coral just right, and the Clark's Anemonefish are usually buzzing around their Bubble Coral homes. Keep an eye out for the more unusual residents, too. We’ve spotted Spitlure Frogfish camouflaged perfectly, and sometimes, if you’re lucky, a Long-beaked Dolphin will cruise by. It's a fairly mellow dive, making it great for those who want to take their time and really soak in the smaller details, though stronger currents can occasionally pick up. It's a truly vibrant example of the GBR, showcasing its everyday brilliance.
