Dunk Island is 20 minutes from Mission Beach by boat. It sits inside the Great Barrier Reef Marine Park, surrounded by fringing reef, covered in national park rainforest, and home to walking tracks, white sand beaches, a café, and camping. You can visit for half a day or stay overnight. Most people don’t realise it’s this close. They drive two hours north to Cairns and catch a boat to Green Island or Fitzroy Island instead. The reef is the same system. The experience is not.

This guide covers how to get to Dunk Island from Mission Beach, what you can do once you’re there, what the snorkelling tour includes, what it costs, and how it compares to the alternatives.
How do you get to Dunk Island from Mission Beach?
By boat from Clump Point, which is a five-minute drive from Mission Beach village. Free parking at the boat ramp. The crossing takes roughly 20 minutes depending on conditions.
There are two ways to get across. You can catch the Dunk Island ferry for a self-guided day trip. Or you can book a snorkelling tour that includes the crossing, guided reef snorkelling, and island time as part of one package.
No bus transfer. No two-hour drive. You’re on the island before most reef tours from Cairns have left the marina.
What can you do on Dunk Island?
More than most people expect from a half-day trip.
Beaches. Brammo Bay is the main beach. Sheltered, clean, palm-lined. Muggy Muggy Beach is a 40-minute walk through rainforest and coastal woodland on the other side of the island. Quieter. Often empty.
Walking tracks. The island is mostly national park. The Muggy Muggy track is 3km return and flat. The Mt Kootaloo summit track is 7km return, steep, and takes you through ancient fern forest past World War II radar station remains to the highest point on the island. Views north to Hinchinbrook, south to the Family Islands.
Snorkelling. The fringing reef around Dunk Island is accessible straight off the beach in places. For the outer reef, the guided snorkelling tour takes you to Beaver Reef and surrounding sites where the coral and marine life are denser.
Wildlife. Dunk Island has its own population of cassowaries. You might see one on the walking tracks. Green sea turtles are common in the waters around the island. Dolphins, reef fish, giant clams, and seasonal manta rays (summer) are part of the snorkelling experience.
Café. The island café at Brammo Bay is open for day visitors. Licensed. Meals, coffee, cold drinks. You don’t need to pack a full day’s food.
Camping and glamping. The Dunk Island campgrounds reopened in 2025 with upgraded facilities and new glamping tents on Brammo Bay. If half a day isn’t enough, you can stay overnight. Book direct through Dunk Island at https://dunkisland.com/.
What does the snorkelling tour include?
Wildside runs small-group snorkelling tours to Dunk Island and the Great Barrier Reef. Here’s what you get.
Group size. 10 people maximum. That’s the whole boat. Not 10 people in your subgroup on a vessel carrying 80. Ten total.
Gear. Snorkel, mask, and fins fitted before departure. Wetsuit or stinger suit provided depending on the season. Stinger suits November through May. Wetsuits available year-round for warmth.
Guide. Your guide is in the water with you. Not standing on a pontoon pointing at things. Swimming alongside, finding marine life, adjusting the route to conditions. This is a guided snorkel, not a self-directed swim near a moored boat.
Duration. Half-day tour. Morning departure from Mission Beach. 20-minute boat ride. Snorkelling time at the reef. Time on Dunk Island. Return by early afternoon. You still have the rest of the day.
What to bring. Towel, sunscreen (reef-safe preferred), hat, water, and shoes you can get wet. Leave valuables at your accommodation.
Season. Year-round. Summer brings warmer water, coral spawning, and manta rays. Winter brings calmer seas and clearer visibility. Both are good. Conditions vary day to day more than season to season.
What does it cost?
Snorkelling tours are $150pp. Pricing is confirmed at booking. Call (07) 4088 6212 or book online. Ferry-only day trips are a separate option if you want to explore the island without the guided snorkel.
The Wild Tully + Dunk deal. Half day trips to Dunk Island for Great Barrier Reef snorkelling, secluded beaches and hidden caves. Plus half day white water rafting grade 2-3 rapids on the Tully river. 2 x half day package deal. Save $20. Call to book.
How does Dunk Island compare to Green Island and Fitzroy Island?
This is the question most people researching FNQ reef trips are actually asking. Here’s an honest comparison.
Green Island
Fitzroy Island
Dunk Island
Green Island is 45 minutes from Cairns by catamaran. It’s small, flat, and very popular. On a busy day, Green Island receives over 1,000 visitors. The snorkelling is decent but the beaches are shared with a lot of people. Glass-bottom boats, an underwater observatory, a resort, and a pool. It’s a polished, high-volume operation. If you want convenience from Cairns and don’t mind crowds, it does the job.
Fitzroy Island is also 45 minutes from Cairns. Larger, more rugged, better hiking. The snorkelling at Nudey Beach is good. A turtle rehabilitation centre gives it a point of difference. Fewer visitors than Green Island but still a busy day trip destination. Better for people who want to hike and snorkel rather than just snorkel.
Dunk Island is 20 minutes from Mission Beach. Smaller visitor numbers by a wide margin. National park rainforest, cassowaries, walking tracks from flat to steep. The snorkelling tour is capped at 10 people with an in-water guide. The fringing reef is part of the same Great Barrier Reef Marine Park. The difference is the experience: you’re not in a queue, you’re not on a pontoon, and your guide knows your name.
The trade-off is access. Green Island and Fitzroy Island are easy day trips from Cairns, which is where most international flights land. Dunk Island requires getting to Mission Beach first, which is about 2 hours south of Cairns. If you’re already based at Mission Beach, there’s no comparison. If you’re based in Cairns and have limited time, Green or Fitzroy is more convenient.
If you have the time and the choice, Dunk Island is the quieter, more personal experience on the same reef system.
When is the best time to visit Dunk Island?
Year-round. The dry season (May to October) brings clear skies, calm seas, and the best underwater visibility. The wet season (November to April) brings warmer water, occasional rain, coral spawning, and the chance of manta rays. The Tully River also runs higher in the wet, which means better rafting if you’re combining activities.
Avoid public holiday weekends if you want the island to yourself. Midweek is always quieter.
What should you bring to Dunk Island?
For the snorkelling tour: Towel, reef-safe sunscreen, hat, water, wet-suitable shoes. All snorkelling gear is provided.
For a day trip (ferry only): Everything above plus food and water if you don’t want to rely on the café. Comfortable walking shoes if you’re doing the summit track. Insect repellent for the rainforest sections.
For overnight camping: Tent, sleeping gear, torch, food, and water. The campground has basic facilities. Book ahead through the Mission Beach Visitor Information Centre.
