Michaelmas Cay Qld Aus

Michaelmas Cay, located on the western end of Michaelmas Reef, is part of the Michaelmas and Upolu Cays National Park and the larger UNESCO Word Heritage Great Barrier Reef. The 1.8ha cay is formed of the broken coral and shells which currents brought over and onto the reef and over time the cay has been covered partially with beach spinifex, stalky grass, sea purslane, beach morning glory and bulls head or puncture vine.

Michaelmas Cay is considered one of the most important seabird breeding areas on the Great Barrier Reef with up to 20,000 pairs of seabird at the height of the season. As a result of the many seabirds the cay even had a guano mining lease in the early 20th century. Sooty Terns, Crested Terns, Lesser Crested Terns and Common Noddies nest all year round and another at least 12 species of seabirds have been recorded. Green sea turtles are seen occasionally and the reefs are an excellent area for snorkeling with visitors coming from Cairns, some 40 kilometers away.
