Michaelmas Cay

Great Barrier Reef, Cairns

The Basics

To reduce environmental impact, access to the island is limited to a small portion of the beach. Michaelmas Cay is typically visited on catamaran cruises from Cairns, which offer snorkeling and scuba diving, and are usually led by marine biologists who explain the unique environment of the coral cay and reef. See the reef without getting wet on a semi-submarine tour or, for an alternative perspective, take a scenic flight over the Great Barrier Reef.

When to Get There

Unlike other cays, Michaelmas Cay is always above water, so you can visit regardless of the tide. The best time to observe birds is during the summer breeding season, while optimum scuba diving conditions occur between June and October, when there’s typically less rainfall and therefore better visibility.
