Thetford Reef Dive Site

Cairns, Cairns Area

Thetford Reef, nestled close to the Cairns coast and just a short boat trip from the popular Green Island, is a two kilometre long burst of colour - with scattered coral heads, sandy floor areas inviting glittering schools of sea life, and lots of swim-throughs for adventure-seekers. Giant clams, butterflyfish, rabbitfish, damsels, angelfish and pipefish are always visible among the large gorgonian fans and soft coral. Anemones full of cheeky anemone fish and coral heads covered in multi-coloured Christmas worms make for colourful photos. Thetford Reef is also circled by larger pelagic fish, including mackerel, tuna, trevally, wrasse, spangled emperor, red bass, blue and gold fusiliers and sergeant majors.
