About this tour
Board a catamaran from Cairns for a full-day expedition to Michaelmas Cay, a pristine sand island ringed by thriving coral gardens on the Great Barrier Reef. Spend four hours exploring the cay itself, where you can snorkel directly from the shore, descend in a climate-controlled semi-submersible to observe coral and marine life without getting wet, or take a scuba dive if certified. Marine biologists deliver talks throughout the day. Meals and refreshments—morning tea, a hot and cold buffet lunch with prawns, afternoon tea, and complimentary bubbles—keep you fuelled between water time.

What to expect
You'll depart Cairns by catamaran, arriving at Michaelmas Cay mid-morning. The island itself is small and sheltered; most visit to snorkel the fringing reef directly from the beach, where visibility is typically clear. If you prefer to observe without getting in, the semi-submersible—an air-conditioned vessel with windows below the waterline—cruises the reef's outer edge, bringing coral and fauna within arm's reach. Divers (12+ with certification) can do a guided descent; others simply watch from the boat or cay. Between activities, you'll gather on deck for talks about reef ecology and conservation. The day is unhurried: four full hours at the cay lets you choose your own pace.
Good to know
Snorkel gear and rash suit (lyra) are provided. Divers must complete a health questionnaire; some medical conditions exclude participation. Wait 12 hours after a single dive before flying or ascending above 300 metres; 24 hours if doing multiple dives. Bring sunscreen, hat, and towel.
