Michaelmas and Upolo Cays National Park
Michaelmas Cay, part of Michaelmas and Upolo Cays National Park, is one of the most important seabird breeding sites in the Great Barrier Reef World Heritage Area. Michaelmas Cay is a small, low sand cay, covered by grasses and low-growing plants. Upolu Cay is a low, unvegetated sand cay.
From the fenced beach access area on Michaelmas Cay, watch seabirds nesting and tending their young without disturbing them. Marvel at the sight of up to 30,000 seabirds occupying the cay at peak nesting periods during summer. Look for sooty terns, common noddies and crested terns. Admire huge flocks of seabirds filling the sky. Go snorkelling to explore the diverse surrounding reefs. Public moorings are provided for private boats.
