A guide to the best snorkelling and diving spots in 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.

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

Keep your eyes peeled for hawksbill turtles at Upolu Reef.

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.

Blacktip sharks come lurking around Saxon Reef.

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.

9. Hastings Reef

What it offers: A favourite snorkelling spot
Number of dive sites: Nine

One of the shallower spots on the Outer Reef, a real highlight of Hastings Reef, is its dive site, Fish Bowl. Sitting around five meters under the surface of the water, Fish Bowl is home to plenty of healthy, strong coral growth.

You may even spot turtles at Hastings along with a large school of humphead parrotfish. Tour operators Reef Experience, Reef Encounter and Divers Den visit Saxon Reef.

10. Agincourt Reef

What it offers: Incredible coral formations
Number of dive sites: 30

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.

7 wellness experiences on Hamilton Island for complete rejuvenation

    Conjuring calm and active adventure in equal measure, Hamilton Island is a tropical tonic for body and mind.

    Hamilton Island knows a thing or two about indulgence. There are long lunches to linger over, seafood towers to savour and poolside loungers designed for guilt-free idling. But for health-minded travellers wanting to feel energised inside and out, this sliver of the Whitsundays takes wellbeing just as seriously. Think yoga mats rolling out at dawn, kayaks skimming turquoise water, state-of-the-art fitness facilities and spa therapists working tropical magic. These Hamilton Island wellness experiences promise to restore, rebalance and leave you feeling brand new.

    1. E-Mountain biking

    For travellers with an appetite for adrenaline, Hamilton Island’s new self-guided e-mountain biking experience is worth carving out a morning for. Start at HI Trails HQ, where you’ll be fitted with a full-suspension, pedal-assisted e-mountain bike and given a run-through of a nine-kilometre section of the island’s 25-kilometre trail network. The electric boost makes the ride more accessible (and the climbs more manageable), though an intermediate level of fitness is still recommended.

    As a first-time mountain biker, I start off wobbly – taking my time to get used to switching gears and electric modes – and wonder if I’ve overestimated my coordination. But soon something clicks. Suddenly we’re zooming through pockets of eucalyptus and out onto ridgelines with sweeping views of electric blue waters, catching our breath at hidden bays with barely another soul in sight. More than 70 per cent of the island remains untouched, so witnessing these lesser-explored pockets feels like a blessing. It’s the kind of adventure that leaves you buzzing, accomplished and blissfully tired out.

    2. HI Fitness Club

    If mountain biking isn’t quite your speed, there are plenty of other ways to stay active on the island. One of the newest Hamilton Island wellness experiences, HI Fitness Club now has 24-hour access, offering a fully equipped modern gym, group classes spanning HIIT to yoga, plus two bubbling spas and a sauna waiting to loosen sore muscles.

    I drop in for a Reformer Pilates class. Each of the four machines has its own mini screen with a wide selection of high-quality virtual classes, meaning I can select one that suits my level and mood that day. Beyond Pilates, the virtual library is like a choose-your-own adventure for fitness enthusiasts: dance, Body Pump, Body Combat and GRIT Cardio are among the options. Or perhaps challenge a family member or friend to a hit of tennis at one of the three courts.

    3. Walking trails

    Get the blood pumping on a morning run.

    We set out early. By 6:45am, we’re halfway up Passage Peak, the highest point on Hamilton Island and widely considered its most impressive vantage point. From the Scenic Trail Entrance, the viewing platform takes around an hour to reach by foot, with moderate inclines that will get your heart pumping without feeling too punishing. The payoff at the top is immediate. Bush-clad Whitsundays islands scatter across the horizon in every direction, the sunrise brushing the scene with soft melon and gold tones. I take my time soaking up the 360° panorama, remembering how powerful an active start in nature can be for clearing the mind and energising the day ahead.

    While Passage Peak is one of the most popular hikes on Hamilton Island, Flat Top Hill Lookout and the longer Southeast Head Trail are also excellent choices.

    4. Spa wumurdaylin

    Feel your worries melt away at Spa wumurdaylin.

    In a tranquil treatment room at Spa wumurdaylin, the world disappears. The space is all brown stone tiles, bamboo racks and lush garden views, setting the tone for my Soul Temple treatment. My therapist, Kass, begins with a full-body, exfoliating orange buff sugar scrub that feels divine. Next comes the vertical Vichy shower and underwater massage to knead out muscle knots. The sound of cascading water is reminiscent of a tropical rainstorm, and stress becomes a distant memory.

    It’s a prime example of the transportive power of the island’s spa, where guests can come to reset the mind and loosen tension in the body. The menu spans radiance facials to deep release rituals and mud wraps, all using products from pH-balanced skincare brand LaGaia Unedited. Concluding with herbal tea, I leave in a blissful daze.

    5. Sunrise yoga

    Start your day on the right foot.

    Morning movement doesn’t get more surreal than sunrise yoga on The Sundays’ seaside terrace. As we roll out our mats, morning light spills across Catseye Beach below, turning the water into a sheet of molten gold. But the setting only does half the healing. I match my breath to the rhythm of the waves and feel my body gradually lengthen and wake as instructor Tyla Rae guides us through a slow, mindful flow.

    Available exclusively to guests of The Sundays, this session captures the spirit of wellness on Hamilton Island – immersion in nature, slowing down by the sea, recalibrating both body and mind. To round out the experience, the perfect ocean cool-off awaits just steps away.

    6. Getting out on the water

    Try your hand at a host of watersports.

    Speaking of ocean delights, Catseye Beach’s host of watersports delivers spades of fun and rejuvenation. Glide over the crystalline water in a kayak, test your sailing skills in a mini catamaran, spot schools of fish (and a turtle if you’re lucky) from a stand-up paddleboard, or slip into an underwater wonderland when you snorkel off the beach.

    Out here, the water is so clear it feels like floating in glass, and the green silhouettes of the Whitsunday Islands rise on the horizon. Half an hour on the water here is all you need to reset your entire mood.

    Guests staying at qualia, Beach Club, The Sundays, Reef View Hotel, Palm Bungalows and Hamilton Island Holiday Homes have complimentary access to all these water activities, making it easy to dive right in.

    7. Take a swing

    For others, mindfulness comes from calm concentration – and golf fits the bill to a tee. Designed by five-time British Open winner Peter Thomson, Hamilton Island Golf Club is perched along the scenic ridges of Dent Island. It’s Australia’s only golf course on its own island, making it one of the most scenic golf courses in the world. The experience is suitable for golfers of all skill levels, with spectator bookings also available for those simply wishing to take in the views. Follow the game with a well-earned lunch at the Clubhouse restaurant.
