The cruise departed on time, and it was very thoughtful of the team to call and check whether we were on our way. The crew were friendly and helpful throughout the trip, and the food offered for lunch was tasty with a good variety of options. The glass-bottom boat was a highlight for my mom, as she preferred not to go into the water, so it was great that she could still enjoy seeing the fish. The island itself was beautiful and perfect for snorkelling.

Island is relatively small but very enjoyable to walk around it. I did snorkling and it was amazing: unlike in open ocean snorkling (i paid double price for it) where very little could be seen, here just next to deck such a diverse fish. Coral not so much but variety of fish was amazing. Many sharks was a bonus:) A double bonus for many turtles that simply live there so they can be always seen. It was amazing The only minus: masks are one size fits all so better to have your own mask

Journey to Green Island aboard the spacious 'Big Cat' catamaran and enjoy a full day exploring this unique coral cay, where vibrant reef meets lush rainforest—entirely at your own pace.

Choose how you'll witness the underwater magic. Snorkel straight off the pristine beaches, glide over coral gardens on a glass-bottom boat tour, or descend for a submariner's view in our semi-submarine. Guided snorkel safaris are also available.

Wander shaded rainforest boardwalks under ancient trees, relax on sun-kissed white sand beaches, or dive into the turquoise waters. Enjoy up to 5 hours of leisure time to explore Green Island's beaches and rainforest trails independently.

For a fully planned day, opt for the tour that includes a buffet lunch. You'll enjoy freshly-prepared hot and cold items with native Australian ingredients from an award-winning restaurant.

We were amused by glassboat, the captain was very professional, kind and funny. We also saw many types of corals and fishes. Luckily we saw a green trutle as well.

We had a great day but the weather was terrible. When getting off the boat we were told the glass bottom boat had been cancelled. When reboarding they were running. It would have been nice to get a message to say they could reschedule it when it was safe.

Your Great Barrier Reef adventure begins at the Cairns Reef Fleet Terminal. Check-in is seamless, and soon you'll step aboard the MV Big Cat—a 35-meter catamaran designed for comfort. Find your perfect spot in the air-conditioned lounge, out on the sun deck, grab a drink from the bar, and get ready for a stunning cruise.

A scenic 45-minute journey across the turquoise waters brings you to Green Island—a beautiful coral cay where lush rainforest meets the wonders of the Great Barrier Reef. Once you arrive, nearly five hours are yours to craft your perfect tropical escape. Will you stroll the peaceful boardwalk beneath towering palms, take a refreshing dip in the ocean, or simply find a patch of sand to soak up the Queensland sun?

Choose your reef adventure

How will you connect with the world-famous reef today? Your pre-booked choice ensures you experience it your way:

Snorkelling: Grab your included gear and step straight off the beach into a world of colourful fish and coral gardens. It's easy, accessible, and instantly rewarding.

Glass-bottom boat: Prefer to stay dry? Glide effortlessly over the reef, gazing down at the coral formations and marine life while your guide shares fascinating insights.

Semi-submarine: Immerse yourself without getting wet! Descend below the waterline for a diver's perspective, looking out through panoramic windows at the underwater spectacle.

Guided snorkel safari: Join expert guides to explore prime snorkelling spots, perfect for boosting confidence or seeing even more diverse marine life.

Buffet lunch: Add a buffet lunch featuring hot and cold selections.

Back on the 'Big Cat' between adventures, you'll find plenty of space to relax. Since no lunch is included, you have maximum flexibility. Pack your favourite snacks and lunch, or purchase drinks and light refreshments from the licensed onboard bar whenever you feel like it. The friendly crew is always available for assistance, gear fitting, and local tips.

As the afternoon winds down, you'll board the 'Big Cat' for the relaxing cruise back to Cairns. Arrive in the late afternoon with sun-kissed skin, maybe some salt in your hair, and a camera full of incredible reef and rainforest moments.
