Great Adventures is based in Cairns and operates an exciting range of day tours to the iconic Great Barrier Reef. Modern high speed catamarans depart daily to whisk guests away in comfort to the spectacular outer reaches of the Great Barrier Reef and the unique reef and the beautiful rainforest-clad Green Island.

Outer Reef Cruises: Guests of all ages can experience this World Heritage environment. Snorkel and dive amongst beautiful coral gardens, or if you choose to stay dry, you can still embrace the natural wonderland below in the underwater observatory, or from the comfort of their spacious semi-submersible. For the ultimate reef and island experience in one day, Great Adventures offers the choice of combining the Outer Barrier Reef cruise with a two hour stopover on Green Island.

Green Island Cruises: Great Adventures offers three exciting cruises to Green Island, a beautiful 6,000-year old coral cay. With a choice of three daily departure times and taking just 45 minutes to cross the Coral Sea, this is the fastest cruise to Green Island - giving you more time to enjoy this Great Barrier Reef Island!

All of Great Adventures cruises are accredited with Advanced Ecotourism Certification.
