Snorkelling Cairns on The Great Barrier Reef Marine Park"Ocean Free" or "Ocean Freedom" - CHOOSE THE Great barrier reef tour DESTINATION THAT SUITS YOU

Ocean Free, the 16m  schooner sails you to a mooring on Pinnacle Reef, just 1km offshore from Green Island on the Great Barrier Reef, with transfers to the island during the day. Snorkel, dive straight off the boat on this exclusive Ocean Free reef site  with a maximum of only 25 guests for an incredibly customer-focussed snorkel experience. Learn about the reef and start to feel that deep connection to nature – it will get a “hold” on you! After a morning of water activities and a large smorgasbord lunch on board, transfer by tender to Green Island Beach where you can relax  on the coral cay “sand”, take an interpretative walk across the island or visit Marine Land Melanesia and view some  crocodiles (in captivity! ) and other artefacts from the region (small direct fee applies). After 4 and 1/2 hours between reef and island we set sail back to Cairns. The only  company in Cairns to have a personal sail, reef  and  Green Island experience. Be at one with nature with a small group of like-minded people!

Ocean Freedom, the 20m luxury cruising CAT goes to two very unique and different Great Barrier Reef destinations, “Wonder Wall” on the Outer Edge of Upolu Reef and  Upolu Cay Reef.  This tour has 6 hrs of actual reef time – more than any other Cairns reef tour so plenty of time to totally immerse yourself in all that is reef! With complimentary informative Glass Bottom Boat (subject to sea conditions on the day) and Adventure Drift Snorkel Tours, led by our  passionate, knowledgeable Master Reef guides and Marine Interpreters, you will engage and learn about the reef and then, we have no doubt,  start  to feel this deep connection to nature that we all share.

All our Great Barrier Reef sites  are a part of the Cairns Great Barrier Reef Marine Park zone and  World Heritage Area.

Cairns Premier Reef and Island Tours view their Island and Cay destinations as their natural pontoons sitting on the Great Barrier Reef. Both these Cairns snorkel and dive reef tours cater for small numbers, offering truly personalised service where you not only get to snorkel and dive the beautiful Great Barrier Reef (GBR), but also get to experience an eco-friendly developed coral cay Island (Green Island) or a changing coral cay, sitting in the middle of the ocean (Upolu Cay). Get well fed and relax on the sail home or cruise back to Cairns while reflecting on the days’ reef snorkelling adventures.

These Cairns snorkel and dive reef experiences are must do in Cairns!

Green Island lies 27km offshore from Cairns; it is a National Park within the Great Barrier Reef World Heritage Area. It has been a popular tourist snorkelling destination for over a century. In 1937 it became a National Park, in 1974 a Marine Park and then in 1981, part of the Great Barrier Reef World Heritage Area. This island is a true coral cay formed over thousands of years by the build-up of sand and coral rubble, deposited on the calm side of a platform reef. When the tide is low, you can walk along the water around the whole island (1.6km), look out for turtles, stingrays and sea birds. You can also just chill out on the beautiful golden sandy beaches, or swim in the crystal waters surrounding the beaches (if you are not a strong swimmer, make sure you swim in the area patrolled by the Life Guards on the beach). You can even enjoy a cocktail at the bar (remember no alcohol though if you are doing any more diving).

More Info


Ocean Freedom has two very unique and stunning Great Barrier Reef snorkel and dive sites, one close to Upolu Cay and the other on the outer edge of Upolu Reef. Upolu Cay Reef is a beautiful coral formation surrounded by crystal clear, turquoise water. On days where conditions allow, guests can be transferred across to the cay in our large tender. Once there, they can laze on the cay, swim in the shallow waters or take a snorkel tour back to the main vessel, viewing coral and sea life on the way, under the watchful eye of our lookouts. On other days where the Cay is not accessible, they can still snorkel the stunning aquarium-like shallow waters and coral gardens. Anyone needing assistance is supplied with the necessary buoyancy aids and guided back with one of our crew. At our second site Outer Edge Upolu Reef, guests are stunned by the amazing ‘Wonder Wall’ streaming with sea life. Crew comment they’ve never seen so many different Nemo species on one site. Guests are treated to an engaging and informative Glass Bottom Boat Tour and also an Adventure Drift Snorkel tour with our marine naturalist, under the watchful eye of our look outs. Once you learn about the magic of the reef and its inhabitants with our enthusiastic and knowledgeable reef guides, your connection to the Great Barrier Reef grows stronger! Order of sites visited is dependent on conditions on the day.
