    Switzer Reef might not shout its name from the rooftops like some of its GBR neighbours, but for those who know, it's a real treat. We love coming here for the sheer density of hard corals, especially the big, sculptural brain corals that just dominate the reefscape. It feels ancient, a proper old-growth forest of the sea. Drop in and you're surrounded by these impressive coral structures, home to surprising bursts of colour from parrotfish and the occasional silver flash of school mackerel cruising by. Look closer and you'll find the smaller residents, like the fascinating silver-cheeked toadfish, often tucked into crevices. While it's a relatively easy drift, the currents can pick up, so it suits divers comfortable managing that. Our favourite time to visit is mid-morning, when the sun angle really brings out the subtle purples and greens in the cactus and smooth cauliflower corals. It's a fantastic spot for photographers keen on capturing dramatic reef architecture without battling crowds.

    Safety Notes
