Michaelmas Cay
Located 22 nautical miles (40 km) from Cairns, the same as the distance across the English Channel, and close to the outer reef systems, Michaelmas Cay is the largest of the uninhabited coral cays in the Cairns region; in fact it is huge in comparison. Seastar is the first vessel to arrive at Michaelmas Cay. Very few tour vessels are now permitted access to this sensitive island and now there are only two which travel daily that are permitted the right to use and access the Cay.
Outer Great Barrier Reef Snorkel Tour includes luxury catamaran cruise all equipment and two guided snorkel tours

Great day; awesome snorkelling experience - saw such amazing fish and coral as well as a turtle and a shark (pretty close up). Weather was raining in Cairns but beautiful where we went and visibility under the water was incredible.
