Green Island might only be a 45-minute hop from the mainland, but it feels like you’ve dropped into another world — one where turtles cruise by, trees grow from coral, and cassowaries occasionally strut through the undergrowth (yep, really).
Whether you’re just popping over for a half-day reef fix or staying the night for that peaceful after-hours magic, Green Island proves that you don’t need to go far to feel far away.
A Bit of History
Green Island — or Wunyami, as it’s traditionally known — has long been a place of significance for the Aboriginal people of the region. Historically used as a seasonal sea country base, it was vital for marine life harvesting, cultural ceremonies, and storytelling.
In more modern history, the island became a hub for commercial charter boats and tourism in the early 20th century. It now forms part of the Green Island Great Barrier Reef marine park, co-managed by Queensland Parks and the Traditional Owners, helping preserve both its cultural and ecological values.
Oh, and the crocs? They’re a more recent twist — courtesy of Marineland Melanesia Crocodile Park, a one-of-a-kind blend of wildlife sanctuary and cultural museum that now calls the island home.
What makes Green Island so special?
Few places offer an island reef environment where coral reefs, colourful bird life, and island rainforests coexist — all within walking distance. This cay might be compact, but it’s brimming with natural wonders, insect life, and marine biodiversity.
You’ll also find educational opportunities through Reef Biosearch and marine biologist activities that dive deep (pun intended) into reef ecology and conservation. There’s even the Guided Island Eco Walk and
Things to do on the Island
Snorkelling straight off the beach
This is no gimmick. You can hire snorkel equipment or join a boat snorkel trip and be swimming among abundant sea life within minutes. No long transfers or complicated instructions — just grab your gear and walk into the water from the sandy beach.
The reef here is shallow, calm, and full of activity: giant sea turtles, damselfish, anemones, and rays often glide through these protected waters. Snorkel equipment hire is available near the Green Island day-use area, close to the beach hire hut.
If you’re booking a glass-bottom boat & snorkelling combo, you can cover both perspectives in one smooth go.
Glass-bottom boat tours and semi-submarine rides
The glass-bottom boat tour is a staple here, not just for the kids or those who forgot their swimsuits. These cruises are narrated by a glass-bottom boat guide and float across shallow reefs teeming with aquatic life. They’re a fab way to appreciate the outer reef structures from the comfort of a dry seat.
For something deeper (literally), the Semi-Submarine glides underwater through the deeper parts of the reef. It’s one of the top glass-bottom boat activities for travellers after a bit more immersion, minus the wetsuit.
Marineland Melanesia (Croc Sanctuary + Artefacts)
Equal parts thrilling and cultural, Marineland Melanesia is more than just a crocodile park. Sure, you’ll see the world’s largest captive saltwater croc (yes, Cassius is very much real). But you’ll also walk through Melanesian artefacts, war clubs, ceremonial masks, and oceanic carvings that paint a deeper picture of our regional neighbours across the Torres Strait and beyond.
This centre for visitors offers croc feedings, educational talks, and close-up views of creatures that are more ‘prehistoric tank’ than petting zoo residents.
Island Walks and Rainforest Trails
The Green Island Eco Walk and Island Walk loop through lush terrain where rainforest plants jostle for space with strangler figs and mangroves. This isn’t just a bunch of palms stuck in sand — this is genuine rainforest, growing on coral.The boardwalk is wheelchair accessible, making it a good shout for families or those with mobility needs. You might spot butterflies, sunbirds, or a goanna if you’re lucky. Interpretive signs along the way offer insight into the island reef environment and traditional bush uses.
Scuba diving and marine biology programs
First-time divers can book an introductory dive while seasoned divers head out to reef sites off the cay’s edge. The diving here isn’t as deep or dramatic as spots further offshore, but it’s great for getting up close to coral gardens and marine life in a more relaxed setting. Some operators offer dives with a marine biologist, where you’ll learn about reef resilience, coral bleaching, and fish behaviours — straight from the expert floating beside you.
When’s the best time to visit?
Dry Season (May–October)
This is the sweet spot: lower humidity, better visibility for reef activities, and fewer mozzies. Day visitors and resort guests flock in during these months, so book your ferry and Dining Options early if you want a seat with a view.
Wet Season (November–April)
Expect tropical heat, sticky air, and sudden downpours. But also? Fewer crowds, greener rainforest, and turtle nesting on the beaches. Just pack your poncho and a sense of humour.
Keep in mind that stinger season (Nov to May) requires wearing stinger suits — available with most snorkel or boat trip bookings.
How to get there
You’ve got a few solid options:
- Green Island Ferry via the Green Island Reef Rocket Ferry or Great Adventures by Quicksilver
- Private boat trip or commercial charter boats
- Fancy? Book a scenic chopper to the Green Island HeliPad
The Return ferry transfers take about 45 minutes and often include Return transfers from Cairns hotels. Coach transfer options also exist, particularly for families or groups. Make sure you check your Green Island Ferry Times and plan around departure times.
Travel time can vary with tides and weather, so leave some buffer if you’ve got dinner plans back in Cairns.
Green Island Resort & Eco Accommodation
The Green Island Eco Resort (also known as Green Island Resort or Green Island Reef Resort) is your only overnight accommodation, but it’s worth the stay. Guests get Island Suites, private access to the island shore, and first dibs on sunrise swims and post-sunset peace after the day visitors leave.
It’s the perfect choice for resort guests who want that extra layer of reef immersion. Rooms are nestled beneath the canopy, and there’s an island resort shop on site if you forget your swimmers (or your wine).

Respecting the reef, island, and culture
Green Island sits in a marine park on land cared for by generations of Aboriginal people, and its preservation depends on respectful tourism. Here’s how to do your part:
- Never stand or walk on coral — even if it looks dead, it probably isn’t.
- Use only reef-safe sunscreen
- Don’t touch marine life, no matter how curious that green turtle looks
- Dispose of rubbish properly, especially food scraps
- Stay on marked nature trails and boardwalks
- Learn about the Manbarra people and the 5 Manbarra press-ganged Palm Island history — it’s a sobering but important part of our national story
