Cairns Island Tours

“An island off Cairns is not just a destination — it is a completely different relationship with the ocean, the reef, and the horizon.”

Cairns Island Tours — Tropical Island Day Trips from the City

Cairns sits at the gateway to some of Australia’s most beautiful reef islands, with Green Island, Fitzroy Island and the Frankland Islands all reached by fast ferry within 45 to 90 minutes of the city. Each island has a distinct character and a different reef experience — choosing between them is one of the most pleasant travel decisions you’ll make. And for visitors who want to see all three, multi-day island touring from Cairns is entirely achievable.

Green Island — The Classic Coral Cay

Green Island is a 6,000-year-old coral cay — a small island built entirely of coral debris, sitting 27 kilometres northeast of Cairns in the heart of the Great Barrier Reef Marine Park. It is the closest and easiest reef island to reach from Cairns (45 minutes by fast catamaran) and has excellent snorkelling directly from the beach, a beautiful island rainforest, an underwater observatory and a well-equipped day visitor facility. Green Island Resort also offers overnight stays for those who want to experience the island after the day crowds leave.

Fitzroy Island — National Park and Eco-Resort

Fitzroy Island is a genuine continental island with a national park character — granite and rainforest rather than coral sand, with outstanding snorkelling at Welcome Bay (directly from the beach), excellent walking tracks and a comfortable eco-resort. The 45-minute ferry from Cairns is fast and the island feels considerably more remote than its proximity suggests. The combination of good reef access, beautiful bush walks and the resort’s facilities makes Fitzroy particularly versatile as a day trip or overnight stay.

The Frankland Islands — Uninhabited Reef Islands

The Frankland Islands, a group of five uninhabited continental islands south of Cairns with surrounding reef, offer the most genuinely remote island day trip experience from the city. Accessible by day cruise from Deeral south of Cairns, the islands feature excellent snorkelling in pristine reef environments and a wilderness beach experience that cannot be found on the busier islands.

Green Island — The Classic Cairns Island Experience

Green Island is the most accessible reef island from Cairns — a 45-minute high-speed catamaran ride to a coral cay on the inner reef, close enough to the city to suit a short day and far enough out to feel properly offshore. The island’s tiny size (just 12 hectares), its fringe of white sandy beach and the surrounding reef teeming with marine life makes it the definitive Queensland reef island experience. Day visitors have access to snorkelling equipment, glass-bottom boat tours, an underwater observatory and resort facilities. Overnight stays at the Green Island Resort allow the experience of having the island near to yourselves at dawn and dusk — when the light is extraordinary and the reef wildlife is most active.

Fitzroy Island — Rainforest Meets Reef

Fitzroy Island, 45 minutes from Cairns by ferry, is more mountainous and rugged than Green Island — a national park island with dense rainforest, walking tracks, excellent snorkelling and a beautiful resort. The combination of reef access and rainforest walking is unique among the islands reached from Cairns. The resort is excellent — family-friendly, with multiple accommodation categories, a pool, restaurant and dive centre. Day visitors have full access to the beach, snorkelling and walking tracks, making Fitzroy one of the best-value day trip options in the Cairns region.

The Frankland Islands — Wilderness and Solitude

The Frankland Islands are the most remote and least visited of the reef islands within easy reach of Cairns — five uninhabited national park islands reached by a 45-minute cruise from Deeral on the Mulgrave River south of Cairns. The experience here is fundamentally different from the resort islands: no permanent buildings, pristine beaches, exceptional snorkelling on undisturbed reef systems, and the extraordinary quiet of a wilderness island. The Frankland Islands offer a sense of genuine remoteness that is increasingly rare in popular reef destinations. Tours run by Frankland Islands Cruise and Dive include guided reef walks, snorkelling equipment and a catered lunch on the beach.

How an Island Day Fits Together

The islands are the most flexible reef day from Cairns. Green Island is about 45 minutes by fast catamaran, and the Frankland Islands and Fitzroy Island sit within roughly 45 to 90 minutes of the city. Because ferries run several times a day, an island can be a half day or a full day depending on which sailing you take back — which makes the islands the sensible choice when part of your day is already spoken for. To see where each island sits off the coast, compare them on the Cairns Explorer.

If you are here on a cruise ship, that flexibility is the whole point. An island day is usually the best reef option on a port day, because the crossing is short and you choose your own return sailing rather than being tied to a single all day itinerary. Green Island in particular is close enough that even a modest port call leaves real time in the water. Ferries leave from the Reef Fleet Terminal at the Cairns Marina, about a fifteen minute walk from the Cairns Cruise Liner Terminal. Book the return sailing that lands you back with a clear margin before your all aboard time, not the last one of the day.

Island Day Questions

How long does it take to reach the islands from Cairns?

Green Island is about 45 minutes from Cairns by high-speed catamaran. Fitzroy Island is around 45 minutes by ferry, and the Frankland Islands sit within roughly 45 to 90 minutes of the city.

Which Cairns island is best if I only have part of a day?

Green Island. It is the closest, the crossing is short, and because ferries run several times a day you can choose a return sailing that suits the time you actually have rather than committing to a full day itinerary.

Is Green Island on the outer reef?

No. Green Island is a coral cay on the inner reef, which is why the crossing takes about 45 minutes rather than the 90 minutes to two hours needed to reach outer reef sites.

Can I visit a Cairns island on a cruise port day?

Usually yes, and it is often the best reef option available to you. The crossing is short and you choose your own return sailing. Ferries leave from the Reef Fleet Terminal at the Cairns Marina, about a fifteen minute walk from the Cairns Cruise Liner Terminal. Book a return sailing that lands you back with a clear margin before your all aboard time.

What is the difference between Green Island and Fitzroy Island?

Green Island is a small flat coral cay of about 12 hectares with a fringe of white sand and resort facilities. Fitzroy Island is more mountainous and rugged, a national park island with dense rainforest, walking tracks, snorkelling and a resort.

Islands with Children

Island day trips are usually the better first reef experience for a family. The crossing is short, the water is calmer, and there is a beach to retreat to when someone has had enough of snorkelling.

Ideal for younger children, non-swimmers and anyone prone to motion sickness, because you can see coral from a glass-bottomed boat or from the shallows and be back on sand within minutes. Consider a full outer reef trip instead if your family are confident snorkellers hoping for the clearest water and the widest coral. Confirm minimum ages for any diving or activity separately from the boat transfer, in writing, when you book.

A Moment Worth Slowing Down For

Island days have a rhythm that catches people out. The best part is rarely the busiest hour in the middle. It is the first twenty minutes after you step off the boat, before anyone has organised anything, when the island is quiet and the water is still and you have not yet decided what to do. Do not fill that in. It is the bit you will remember.

Before You Book: Check the Marine Forecast

Island crossings are short, but a short crossing in a big sea is still a long half hour. The Bureau of Meteorology publishes the Cairns Coastal Waters Forecast, Cape Tribulation to Cardwell, which gives wind, seas and swell and — most usefully — forecasts seas inside and outside the reef separately. The Bureau cautions that these forecasts are averages: gusts can be forty per cent stronger than forecast and maximum waves can be twice the forecast height. Routine forecasts are issued at 9:00 am and 3:00 pm eastern standard time. We link to the live forecast rather than repeat figures that change twice a day.
