Green Island, Fitzroy Island, Frankland Islands and Michaelmas Cay — we reviewed every operator. Here's who stood out, and why.
Cairns is the gateway to some of the most accessible tropical islands in the world — each one completely different in character. Green Island is a living coral cay right on the Great Barrier Reef: small, reef-fringed, and easy to reach in 45 minutes. Fitzroy Island is a continental island draped in rainforest, with excellent reef access directly from its beaches and more active pursuits than any other island nearby.
Frankland Islands are five uninhabited coral islands in a national park — remote enough that only one operator is licensed to take you there, which means the reef stays uncrowded. And Michaelmas Cay, the furthest out at 55 km, sits on the outer reef and doubles as one of Queensland's most important seabird nesting grounds.
We spent time on each island and compared every operator that departs Cairns. What follows is an honest breakdown — prices, inclusions, what's genuinely worth paying for, and who we think gets it right.
How we review: All prices and inclusions are sourced directly from operator websites, verified via their live booking systems. Prices are current for April 2026–March 2027 and include GST. Fuel levies are noted separately where applicable.
All four islands depart from Cairns Reef Fleet Terminal, 1 Spence St. Green Island and Fitzroy are 45 min each. Frankland and Michaelmas are further out.

Green Island is a 6,000-year-old coral cay sitting directly on the Great Barrier Reef, 27 km from Cairns. It's the only inhabited coral cay in the region — small enough to walk around in 20 minutes, but rich enough to keep you occupied all day. Three operators run daily tours, each with a different angle on the same destination.
Best Value
The most popular Green Island day tour — 5.5 hours on the island with your choice of snorkel gear or a glass-bottom boat tour included. No fuel levy, no surprise charges. Half-day available at the same price.
Most Inclusions
Three tiers to choose from. The most popular is the Discovery package ($156/adult) — snorkel gear, glass-bottom boat, exclusive pool access and a beach bag. Even the ferry-only ($112) includes a marine biologist talk and eco walk. Up to 7 hours on the island.
Most Exclusive
The only genuine sailing tour to Green Island — a 16-metre schooner, max 25 guests, engine off when the wind allows. Ocean Free visits Pinnacle Reef, an exclusive mooring 1 km off the island. Full seafood lunch, snorkel gear and guided tour all included.
Fitzroy Island is a continental island — meaning it was once part of mainland Australia. The result is something fundamentally different from Green Island: dense tropical rainforest, a summit with panoramic views, walking tracks, and a fringing reef you can snorkel directly from the beach. It's the island for people who want to actually do something with their day.
Honest note: Nudey Beach — regularly voted one of Australia's best beaches — is made of crushed coral, not fine sand. It's beautiful, but manage expectations if you're after a classic sandy stretch.
Best Value
Fitzroy Island Adventures is the island's dedicated operator — the only one that runs exclusively to Fitzroy. Their base price of $108 covers the ferry return and up to 6 hours on the island, with no fuel levy. Snorkel gear and activities are add-ons, which means you only pay for what you use.
Best All-Inclusive Package
Sunlover makes Fitzroy Island easy: you pay one price, and snorkel gear, lunch and a glass-bottom boat tour are sorted. Their Best of Island package ($166/adult) is currently the same price as the Value Package until September 2026, making it genuinely excellent value. Departs at 10:15am — a more relaxed start time than Fitzroy Island Adventures, and returns to Cairns at 4:30pm.
Michaelmas Cay is a small white sand coral cay sitting on the outer Great Barrier Reef, 55 km north-northeast of Cairns. It's different from every other island in this list: visitors spend around 4 hours on and around the cay in a protected access zone, with seabirds nesting overhead. It's a boat trip and a landing — genuinely unlike anything else you can do from Cairns in a day.
Best Small Group
SeaStar runs the more intimate tour to Michaelmas Cay — capped at 36 guests and stopping at two locations: Michaelmas Cay and Hastings Reef. Departs 7:30am, returns ~4:15pm. Every inclusion is covered: buffet lunch, morning and afternoon tea, snorkel gear, wetsuits, vests, a glass-bottom boat tour and guided snorkel at both locations.
Best Sailing Experience
Ocean Spirit runs to Michaelmas Cay aboard a 32-metre sailing catamaran — a larger vessel with more guest capacity than SeaStar, but still well-equipped. The price includes EMC ($8.50), and the experience includes a semi-submarine, marine biologist presentations, fish feeding, and sparkling wine on the return journey. Prices valid April 2026–March 2027.
The Frankland Islands are five uninhabited coral islands in a national park about 45 km southeast of Cairns. Only one operator is licensed to go there — which means no other tour groups on the reef, ever. The snorkeling experience here is defined by that exclusivity: guided, unhurried, and without the crowds that follow every other island from Cairns. The journey itself adds to it — coach, a cruise down the Mulgrave River, then a sea crossing to islands most visitors never reach.
Exclusive Operator
This is the only operator licensed to take visitors to the Frankland Islands, which immediately changes the experience. The full day tour is 8.5 hours door-to-door and includes a full buffet lunch, semi-submarine, snorkel, kayak, paddleboard and a guided island walk — all bundled. The express option ($195) is 5.5 hours total with 2.5 hours on the island, still including all water activities.
Short on time? Three operators let you combine destinations in a single day from Cairns — each with a different pairing and price point.
The only same-day combo covering both Green Island and Fitzroy Island. Departs Cairns at 8:30am — 2.5 hours at Fitzroy, then transfer to Green Island for 3.5 hours before returning to Cairns. Snorkel gear or a glass-bottom boat tour is included in the price. Saves up to $63 per adult compared to booking separately.
Sunlover's full-day combo combines a morning at the Moore Reef pontoon — with its waterslide, ocean pool and buffet lunch — followed by an afternoon on Fitzroy Island. It's the only tour in Cairns that gets you to the outer reef AND an island in a single day from the same operator, with snorkelling at both.
Great Adventures combines 2 hours on Green Island with 3 hours on their outer reef platform — including the semi-submarine, underwater observatory and a hot and cold buffet lunch. Departs Cairns 8:30am, arrives Green Island 9:15am, departs for outer reef 11:20am, returns Cairns 5:30pm. Snorkelling at both locations included.
The honest answer depends less on the island and more on what you actually want from the day. Here's how we'd break it down.
Three operators, multiple activity layers, easy access and no long transfers. Big Cat is the most popular and best value at $122. If you want something quieter and more personal, Ocean Free's sailing tour with 25 guests is in a different league entirely — but at $289, you're paying for that difference.
Fitzroy is the one for walkers, snorkellers and people who find "beach resort" days underwhelming. The summit track gives proper views, Nudey Beach (crushed coral, not sand) is striking despite what Instagram might suggest, and the fringing reef is genuinely accessible. Fitzroy Island Adventures at $108 is the cheapest full-day island tour from Cairns.
Michaelmas Cay is unlike everything else on this list. It's on the outer reef, it has 23 species of nesting seabirds, and it combines snorkelling with a genuine landing on a white sand cay in the middle of the ocean. Not the cheapest option, but there's nothing else like it.
The Frankland Islands have one operator and no crowds. The combination of a river cruise, uninhabited islands and excellent reef makes it feel like an expedition rather than a tour. More expensive and further out — but if the reef is the point, this is where to go.
The Two Island Explorer at $196 covers Green Island and Fitzroy Island in one day. It's the best-value combo and genuinely does justice to both islands rather than rushing through them.
Green Island with Big Cat or Great Adventures. Closest island, most facilities, glass-bottom boat option, and no fuel levy. Half-day available if kids tire out. Great Adventures has a dedicated kids' ocean pool (exclusive to their tours).
Frankland Islands for the best uncrowded reef. Otherwise Fitzroy Island — snorkel directly from the beach at Welcome Bay with a fringing reef right off the sand. Budget around $34 extra for gear if booking Fitzroy Island Adventures.
Green Island is the clear pick — rainforest walks, Marineland Melanesia crocodile habitat, shops, cafes, glass-bottom boat tours and a semi-submarine. You can have a full day without entering the water. Fitzroy Island also has excellent walking tracks and a turtle rehab centre.
Ocean Free to Green Island for the most intimate sailing experience on the reef. Or SeaStar Cruises to Michaelmas Cay — max 36 guests and a genuinely different kind of day that most travellers haven't done.
Fitzroy Island Adventures at $108 adult is the cheapest full island day from Cairns. No fuel levy, up to 6 hours. Bring your own snorkel gear to avoid the $34 hire fee — or skip snorkelling and walk the tracks, which are free.
Answers based on verified operator information as of May 2026.
It depends on what you want. Green Island is the most accessible and versatile, with tours from $112 adult. Fitzroy Island is best for active travellers from $108. Frankland Islands offers the most exclusive snorkelling experience at $195–$270. Michaelmas Cay is the most unique at $265–$288 — a coral sand cay on the outer reef.
Green Island is 27 km northeast — 45 minutes by catamaran. Fitzroy Island is 29 km southeast — also 45 minutes. Frankland Islands are ~45 km southeast — roughly 1.5–2 hours including a coach and river cruise. Michaelmas Cay is the furthest at 55 km north-northeast, taking about 1.5 hours by boat.
Fitzroy Island Adventures at $108 per adult is the cheapest full-day island tour from Cairns — ferry return plus up to 6 hours on the island with no fuel levy. Green Island starts from $112 with Great Adventures (ferry-only, no snorkel gear). Both include genuine island time without cutting the day short.
Nudey Beach is made of crushed coral rather than fine sand — which is beautiful in its own right but noticeably different from a classic sandy beach. It was ranked #1 on Brad Farmer's list of Australia's 101 Best Beaches in 2018 for its scenery, not its texture. Worth visiting, but set the right expectations.
Yes. The Two Island Explorer (Big Cat) covers Green Island and Fitzroy Island for $196 adult. Sunlover's Reef & Island in a Day combines Moore Reef and Fitzroy Island for $337 (+$10 fuel). Great Adventures offers Green Island plus their outer reef platform for $343.
Frankland Islands for dedicated snorkellers — one operator, five uninhabited islands, uncrowded reef. Fitzroy Island also offers excellent snorkelling directly from the beach at Welcome Bay and Nudey Beach. On Green Island, Ocean Free's exclusive mooring at Pinnacle Reef is the standout option for a proper snorkel.
It varies by operator. Frankland Islands (Full Day), Great Adventures Island & Reef Combo, Sunlover Best of Island and SeaStar Cruises all include meals. Big Cat Green Island, Fitzroy Island Adventures and Great Adventures ferry-only do not — lunch is an optional extra. Ocean Free includes a full seafood smorgasbord.
All operators depart from the Reef Fleet Terminal at 1 Spence Street, Cairns — a 5-minute walk from the CBD. Frankland Islands tours also include a coach from Cairns before the boat. Most hotels can arrange transfers to the terminal.
