Our guide to Great Adventures Green Island and Great Barrier Reef Adventure

Enjoy this reef and island experience which takes you to the tropical Green Island and the spectacular outer reaches of the Great Barrier Reef.  

Firstly, a 45-minute catamaran ride will whisk you to the beautiful Green Island, a 6000-year-old coral cay that is home to a unique reef and rainforest combination, which you will get to explore for a couple of hours.

Next, your day of adventure and discovery continues onto a spacious activity platform moored on the majestic Outer Great Barrier Reef. There, you can snorkel and dive directly off the platform amongst beautiful coral gardens and marine life or just relax on the sundeck and enjoy a delicious buffet lunch while taking in the amazing marine scape.

Frequently Asked Questions for Great Adventures Green Island and Great Barrier Reef Adventure

  • How do I check-in before departure?
    Please check-in at the Great Adventures counters inside the Reef Fleet Terminal (1 Spence Street in Cairns) 1 hour before your departure time.
  • Will I get seasick?
    Hopefully not. The large, stable fast catamarans provide very good sea keeping even in rougher ocean conditions. Where there is motion, whether a car, bus, plane or boat, some people will suffer from motion sickness. Motion sickness tablets are available onboard for purchase. There are also ginger tablets as a natural alternative motion sickness medication on a complimentary basis. To be effective, motion sickness medications should be taken immediately on boarding. If you are concerned about potential motion sickness, being closer to the coast, Green Island is a shorter 45 minute journey and is more protected than a cruise to the Outer Reef.
  • Do you supply life jackets?
    Life jackets are onboard for emergency use only. However, flotation/buoyancy vests are available for use whilst swimming or snorkelling. At Green Island, these can be hired from the Dive Shop. For passengers continuing on to the Outer Reef, please help yourself to these from the front of the platform with the rest of your snorkelling equipment.
  • What is the temperature of the water?
    The warm waters of Tropical North Queensland range in temperature from 22-29 Celsius (75-85 Fahrenheit) and make for year round comfort for water activities.

  • If we book a certain return time for a Green Island cruise, can we change to an earlier or later departure once we are over on the Island?
