Michaelmas Cay, on the Great Barrier Reef off Cairns, is 10 kilometres long reef with a sand cay. Explore the bommies, walls, swim-throughs, gullies, small caves and overhangs. Michaelmas Cay is rich with a myriad of sea life including green turtles, blue-spotted Rays molluscs and hundreds of species of tropical reef fish including Humphead Maori Wrasse. The reef surrounding the cay is renowned for an abundance of giant clams. Standing on the beach you may experience fish "biting" at your heels - they're only trying to catch shrimp and other small animals.
