10 Best Snorkelling and Diving Spots near Cairns

Get to know some of the must-see coral reef sites on the Great Barrier Reef.

Although the World Heritage-listed Great Barrier Reef stretches over 2300 kilometres along the Queensland coastline, Cairns is considered to be the official gateway to experience this beauty up close. With 3000 separate reefs and over 900 continental islands and coral cays, it’s the world’s largest coral reef system and has a myriad of unique marine life you won’t find anywhere else.

Now we have the big reef covered, it’s good to keep in mind that each of those 3000 separate reefs has its own dive sites – basically the best spots on the reef where you can enter the water.

Ready to snorkel or dive on one of the seven wonders of the natural world, directly from Cairns? Take your pick from these 10 snorkelling and diving spots.

1. Flynn Reef

What it offers: Fantastic coral gardens
Number of dive sites: Nine

Located around 60 kilometres offshore from Cairns, the popular Flynn Reef is known for its stunning coral gardens and diverse array of marine life.

It’s perfect for snorkelling the shallow waters, as well as scuba diving, as the outer edges of the reef drop away to an average depth of 20 metres. Diving conditions are optimal all year round. Tour operators Silverswift and Passions of Paradise visit Flynn Reef.

2. Milln Reef

What it offers: Beautiful, clear waters
Number of dive sites: 11

Also situated on the outer edge of the Great Barrier Reef is Milln Reef, home to some very famous dive sites – particularly Petaj Mooring, where you can often find large schools of bright, colourful fish called sweetlips hanging around, as well as resident turtles and whitetip reef sharks.

The Whale is another fun dive site with a shallow top creating the effect of a whale’s blowhole during low tide. Tour operators Silverswift, Passions of Paradise and the Pro Dive Cairns Three Day Liveaboard Scuba Dive Trip visit Milln Reef.

3. Pellowe Reef

What it offers: Epic wall dives and swim-throughs
Number of dive sites: Two

A bit smaller than Flynn and Milln Reef is Pellowe Reef, yet it still packs a punch. One of the dive sites is named Cucumber Alley due to the vast number of sea cucumbers that can be found here. The other dive site, Darth Vader, is named due to long deep valleys and caverns that cover up the light, creating a dark, gloomy (but amazing!) atmosphere.

Due to the smaller size of Pellowe Reef, it’s a lot more exposed to windy weather conditions and can only be accessed in extremely satisfactory weather conditions. Tour operators Silverswift, Passions of Paradise and the Pro Dive Cairns Three Day Liveaboard Scuba Dive Trip visit Pellowe Reef.

4. Moore Reef

What it offers: Operators spend the day here
Number of dive sites: 16

In the shape of a giant horseshoe with three outer reef pontoon operators parked here, Moore Reef is massive. The pontoons offer an easy way to explore the reef in the protected waters, so families especially love it here.

Onboard a Sunlover Reef Cruise, you can even swirl down a 30-metre spiralling waterslide into the tropical ocean. Tour operators Passions of Paradise, Sunlover Cruises , Great Adventures and Reef Magic visit Moore Reef.

5. Thetford Reef

What it offers: Opportunity to see larger marine life
Number of dive sites: 11

The two-kilometre-long Thetford Reef site has a bit of everything – great visibility, many coral heads and lots of swim-through canyons and passages to explore.

Cathedral, TUSA Canyons, and Rosco’s are some of its most famous diving sites, and remarkably, whale sharks and dwarf minke whales have been seen passing near this reef. Tour operators Passions of Paradise, Sunlover Cruises, Great Adventures and Reef Magic visit Thetford Reef.

6. Norman Reef

What it offers: Adventure playground for divers
Number of dive sites: 15

Similar to Thetford Reef is Norman Reef, a reasonably large reef and one that’s especially appreciated by scuba divers. Here you can explore the many cliffs, caves, swim-through areas and even a little wreck. The reef’s depth also means that it’s home to a range of larger marine life, such as barracudas, trevally and even the odd reef shark.

The waters near Norman Reef are renowned for having superb visibility. Tour operators Passions of Paradise, Reef Experience, Reef Encounter, Divers Den and Down Under Cruise and Dive visit Norman Reef.

7. Upolu Reef

What it offers: A wide variety of marine life
Number of dive sites: Six

Upolu is a small, protected lagoon-shaped reef with shallow coral gardens and is an excellent place for first-time introductory diving. You can spot a wide variety of marine life here, such as giant clams, sea cucumbers, nudibranchs, cleaner wrasse, yellowtails, giant trevally and large green mauri wrasse.

Often, hawksbill turtles can be found chewing on the red seagrass found growing between the hard and soft corals of the reef. Tour operators Passions of Paradise, Reef Day Tripper and Ocean Freedom visit Upolu Reef.

8. Saxon Reef

What it offers: Ideal night diving conditions
Number of dive sites: Six

Large enough to allow up to three boats at a time to moor, liveaboard dive boats often stop at Saxon Reef to give scuba divers a night experience. Reef sharks can be seen at night, and you can expect to see whitetip, blacktip and grey whaler sharks.

During the day, large shallow coral gardens are exposed where many soft and hard corals thrive and can be viewed either snorkelling or diving. Tour operators Passions of Paradise, Reef Experience, Reef Encounter and Divers Den visit Saxon Reef.

Hop onboard a boat ride from Port Douglas to reach Agincourt Reef, a series of many smaller reefs with at least 16 different dive sites. As the reefs are located on the edge of the continental shelf of Australia, the water quality is spectacular, which creates a pristine environment for marine life and coral colonies.

The Gardens is a particularly popular dive site as they are renowned for its brightly coloured reef fish, making it a photographer’s paradise. Tour operators Quicksilver Cruises , Poseidon Dive and Snorkel and Calypso Reef Cruises visit Agincourt Reef.

Exploring the world’s largest sand island starts with the perfect K’gari homebase.

The morning light is still soft, but it’s already a perfect sunny day. We left our K’gari homebase at Kingfisher Bay Resort with our guide, Peter Meyer, at 9 am to make the most of our time to explore all that the world’s largest sand island holds. The size of K’gari is hard to grasp until you arrive here. This is no sandbar. Stretching 120 kilometres, unique lakes, mangrove systems, rainforest, 75 Miles of beach, historic shipwrecks, small townships and even one of Queensland’s best bakeries are all hidden within its bounds.

But first, one of the island’s most iconic sights: the pure silica sand and crystal clear waters of Lake McKenzie.

Laying eyes on it for the first time, I’m finally able to confirm that the photos don’t lie. The sand is pure white, without the merest hint of yellow. The water fades from a light halo of aqua around the edges to a deeper, royal blue, the deeper it gets (not that it’s particularly deep, six metres at most). The surface remains surprisingly undisturbed, like a mirror.

Arriving with our guide before 10 am means that no one else is around when we get here. Which means we have the pleasure of breaking the smooth surface with our own ripples as we enter. As a self-confessed wimp with chilly water temperatures, my fears are quickly assuaged. Even in the morning, the water stays around 23 degrees – perfect for lazing about all day. But we have more sights to see.

Exploring K’gari

This was the Personalised 4WD tour offered by Kingfisher Bay Resort, and my absolute top pick of experiences. Over the course of the day, we had the freedom to create our own bespoke itinerary (plus a provided picnic lunch along the way), with an expert guide who had plenty of stories and local expertise to give context to what we were looking at. From the history of the SS Maheno shipwreck, which survived the First World War only to be washed ashore by a cyclone in 1935, to a detailed description of how an island made of sand could sustain such diverse flora.

If it’s your first time to K’gari, the Beauty Spots Tour is another great option. Departing daily from Kingfisher Bay Resort (you’ll start to notice a trend, as many of the tours do start and end here), an air-conditioned, 4WD bus takes guests to the island’s most iconic locations, including the best places to swim, like Lake McKenzie and Eli Creek. The latter offers a gentle current, perfect for riding with a blow-up tyre out towards the ocean.

The next day, for a look at a completely different side of K’gari, I joined one of Kingfisher Bay Resort’s Immersive Ranger-guided tours to kayak through the mangroves of Dundonga Creek. This long, snake-like stretch of creek winds its way inland from the ocean outlet we entered by, at times too narrow for three kayaks to be side-by-side. Small insects buzz from leaf to leaf, while birds call overhead. Occasional bubbles indicate we’ve passed some fish that call this place home.

If kayaking isn’t for you – or if, like me, you simply want more – other ranger-led experiences include nature walks and a dedicated Junior Eco Ranger Program for kids ages five to 12 (these run every weekend, and daily over the peak December holidays). Just ask for a timetable of upcoming tours when you check in.

While during whale season, Hervey Bay Whale Watch & Charters operates tours from the hotel’s jetty to get up close to the famous Humpback Highway of Hervey Bay, from 7 November to 31 May, attention turns to the Aqua Oasis Cruise . Departing from the resort every Tuesday, Thursday, Saturday and Sunday for resort guests, adventure along the island’s remote western coast, pointing out wildlife like dolphins, turtles, flying fish and eagles along the way.

The cruise drops anchor so guests can jump into the water using the boat’s equipment – from SUP boards to inflatable slides and jumping platforms. Then refuel with a provided lunch, of course.

Unwind at sunset

As much as days on K’gari can be filled with adventure, to me, the afternoons and evenings there are for unwinding. Sunsets on K’gari are absolutely unbelievable, with Kingfisher Bay on the west side being the best spot to catch the colours.

The Sunset Bar , located at the start of the resort’s jetty and overlooking the beach, is the ultimate location for sundowners. Let chill beats wash over you as you sip on cool wines, beers and cocktails in a relaxed, friendly vibe. Personally, a cheese board was also absolutely called for. As the sun sinks, the sand, sea and horizon turn a vibrant shade of orange, with the jetty casting a dramatic shadow across the water.

When the show is over, head back to the hotel for dinner at the Asian-fusion Dune restaurant, or the pub-style Sand + Wood. But if your appetite is still whetted for more lights and colours, the evening isn’t over yet.

Settle into the Illumina stage for Return to Sky, an immersive light and sound show leading viewers on a captivating journey through K’gari’s stories and landscapes.

Indulge and disconnect

Of course, there is a type of traveller who knows that balance is important, day or night. While Kingfisher Bay Resort offers more than one pool for guests to spend all day lounging by (they’ll even serve you food and drinks while you do it), you’ll find me at the Island Day Spa.

The masseuses could match the magic hands of any big city spa, and I felt the warm welcome as I walked into the light, breezy reception. Choose from a range of botanical facials, beauty treatments and soothing massages using traditional techniques (obviously, I couldn’t go past a relaxing massage). All products used contain organic, native botanical ingredients with nutrient-rich plant extracts to soothe skin and mind. To really indulge, try out one of the packages, couples treatment or even a pre-wedding day offering.

Getting there

Getting to K’gari is shockingly easy. Find daily flights into Hervey Bay from Brisbane, Melbourne and Sydney. Kingfisher Bay Resort offers a shuttle bus between the airport, their headquarters in Hervey Bay and the ferry to take you to K’gari.
