Green Island

Green Island is a beautiful 6000 year old coral cay located in the Great Barrier Reef Marine Park – a premier world heritage site and one of the Seven Natural Wonders of the World.

Just 27km from the hub of Tropical North Queensland, Cairns, Green Island is a 45 minute journey across the Coral Sea with Cairns Adventures’ high speed catamarans. With its unique reef and rainforest environment, this beautiful island provides the one-stop tropical experience.

Green Island is the only coral cay on the Great Barrier Reef with a rainforest growing on it! It is home to 126 native plant species, colourful birdlife, surrounded by magnificent coral gardens and is some 15 hectares (approx 37 acres) in size.

Revel in an array of activities or relax and let your day unfold in this tropical paradise. Stroll through magical rainforest, laze on the white coral sands, swim, dive or snorkel amongst an amazing display of tropical fish and coral gardens, or enjoy the well appointed day visitor facilities, including Green Island Resort's award winning Emeralds Restaurant.


Great Barrier Reef

The beauty of the Great Barrier Reef is yours to experience when you cruise to our mulit-level reef activity platform. Situated on the outer edge of the Great Barrier Reef, our spacious platform features undercover seating and tables to enjoy a delicious buffet lunch, full bar facilities, a swimming enclosure for children, change rooms with freshwater showers, sundeck, and scuba diving facilities with a semi-submerged platform. You will be able to snorkel and dive amongst some of the most spectacular coral gardens and marine life diversity on the Great Barrier Reef.

Or if you choose to stay dry, you can still embrace the natural wonderland below in our underwater observatory and spacious, air-conditioned semi-submersible vessel!



Frequently Asked Questions

Are all seasons suitable for seawalker?
The warm waters of Tropical North Queensland make for year round comfort for water activities. In cooler months however, the complimentary wet suits will keep your body warm.

Will the water pressure make me uncomfortable?

You will descend down the ladder slowly, so it’s easy to equalize the pressure.

Is there a minimum or maximum age limit to do Seawalker?
The minimum age is 12 years old, but there is no upper age limit providing you pass the medical questionnaire.

How deep will we go?
Your instructor will guide you down to around 5 metres deep, an ideal and comfortable depth to experience the reef in a stress free environment.

What if the weather is rainy or cloudy?
You will be walking alongside the coral and fish underneath our platform. Even during poor weather, you will still be able to have a great viewing experience close to the reef and marine life.

Can I take my camera or GoPro underwater?
No. Due to safety procedures you will be unable to take a camera underwater with you however a professional photographer will take your photos and these will be available to purchase.


Can my child try Introductory Diving, Seawalker or Scuba Doo?
The minimum age for these in-water activities is 12 years old. The participant also needs to pass a medical questionnaire as some medical conditions may preclude you from being able to join these tours.

Who can try Seawalker and Scuba Doo?
Seawalker is only available on Green Island. Scuba Doo is only available at the Outer Reef platform. These activities are great options for non-swimmers, children or older people not sure about trying scuba diving or snorkelling. It can even be a great experience for people with minor disabilities. You do need to pass a small medical questionnaire to be able to participate and some medical restrictions apply. The minimum age is 12 years.

Will I get seasick?
Hopefully not. Our 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. We offer 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 towels?
We recommend you bring your own towel. We do have limited towels available for hire however we cannot guarantee availability. These can be collected from the Pool Bar on Green Island, or from the crew on board the vessel if you are travelling 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. 

Do you have prescription masks available?
Standard masks magnify objects underwater by about 25%. We do have prescription masks up to -8.0 available. If you need a prescription mask, please advise us so we can make sure one is available for you as we have a limited supply, especially in the higher prescription strengths. These are hired from the Dive Shop on the Green Island, or included in the price if you are diving.
