7. Green Island & Great Barrier Reef


This full-day tour invites you to experience two of Tropical North Queensland’s most iconic natural wonders — a coral cay rainforest island and the outer reaches of the Great Barrier Reef — in one seamless, expertly-guided adventure. Departing from Cairns on board a comfortable fast catamaran, the itinerary blends exploration, relaxation and reef discovery. The day begins with a visit to the lush rainforest-fringed Green Island, followed by three hours on a purpose-built outer-reef platform designed for everyone — swimmers, snorkellers, non-swimmers alike. With all major snorkel equipment, guided marine-education talks, buffet lunch, and return transfers included, this tour offers a rich, accessible way to immerse yourself in reef and island environments. Whether you’re a first-timer to the reef or a seasoned snorkeler, the combination of rainforest, beach and coral reef makes for a memorable travel day.

Green Island

Green Island is a 6,000-year-old coral cay located within the Great Barrier Reef Marine Park and lies just around 45 minutes by catamaran from Cairns. This tropical island features white coral-sand beaches, a patrolled swimming and snorkelling shoreline, and a lush rainforest interior with boardwalk trails. Here you can snorkel straight from the beach, wander through leafy rainforest, or simply relax beneath the palms. It offers a perfect contrast to the outer reef — a gentle island interlude, before venturing further out.

Outer Reef Platform

Moving beyond the island, the tour continues to a moored activity platform on the outer reef — a floating hub where you’ll spend around three hours immersed in coral-garden life. From this platform you can snorkel amid vibrant fish and coral, dive (for certified or introductory divers), visit the underwater observatory, take a semi-submersible tour, or simply lounge on deck and soak in the vast marine panorama. The outer reef, with its clear water, abundant marine biodiversity and dramatic coral formations, offers the “big-reel” reef experience. Paddle, float, or observe — this location gives you access to the World Heritage‐listed reef in comfort and style.

  • Departure from Cairns: 8:30 am (alternate 10:30 am departure may be available subject to schedule).
  • Return arrival in Cairns: Approximately 5:30 pm.

  • The journey from Cairns to Green Island and the outer reef is conducted aboard a modern high-speed catamaran, offering air-conditioned indoor sections and outdoor decks for viewing and relaxing.
  • The outer reef segment uses a stable, purpose-built activity platform (pontoon) moored on the reef, which provides snorkel access, the underwater observatory, semi-submersible boarding, and sundeck lounging.
  • Onboard the platform and during transit you’ll find lockers for valuables, changing rooms, toilets, bars/snack service (soft drinks, wine & beer available on board), and shaded and sun-loving spaces.
  • The operator is accredited with the regional marine park authority and operates under high-standard eco-tourism certification; its vessels are designed for comfort, safety, and minimal impact on the reef environment.
  • Gear hire (snorkels, fins, buoyancy vests) is included and well-maintained; an experienced crew supports both novice and experienced snorkellers/divers.

What makes this tour different from other reef tours?
This tour combines two distinct reef experiences in one day—time on a tropical coral cay (Green Island) and access to a pristine Outer Reef location. It offers a broader and more diverse experience than visiting a single reef or island destination alone.

Is the tour suitable year-round?
