Where to dive and snorkel on the Great Barrier Reef

Immerse yourself in under-the-sea wonderment with our guide to precisely where to dive and snorkel on the Great Barrier Reef.

One of the seven wonders of the natural world, the Great Barrier Reef is an otherworldly playground for wide-eyed exploration. The largest coral reef system on the planet, it measures in at more than 348,000 square kilometres, a breathtaking labyrinth of caves, caverns, pinnacles, ethereal monuments, boulders, vivid coral and, of course, marine life, just off the northeastern coast of Queensland. But while the delicate ecosystem can be accessed from various points across the state, knowing exactly where to dive and snorkel the Great Barrier Reef is going to showcase the most astonishing sights.

Spanning remote islands and ancient shipwrecks to famed bays, our guide to the best spots is here to elevate your next underwater expedition.

1. Agincourt Reef

What it offers: 16 unique dive sites, caves, vibrant fish life and a mammoth wall dive.

Getting there: High-speed boats from Port Douglas depart frequently, and it’s a 90-minute ride each way.

While more than a dozen individual dive sites will keep water babies busy for days, Agincourt Reef’s main sites offer the stuff of dreams. Located about 65 kilometres northeast of Port Douglas, Agincourt Reef’s Barracuda Bommie (one guess what you’ll spy there), Castle Rock, The Channels (filled with swimmable tunnels), and The Chapel are hugely popular. Agincourt itself sits within the Ribbon Reefs – more on that wider Great Barrier Reef non-negotiable just below – but given this single location’s diverse appeal, it deserves a mention entirely of its own. Ask your guide to point you in the direction of Blue Wonder, too, a wall dive that travels more than 40 metres below the surface.

2. Lady Elliot Island

What it offers: Easy snorkelling and diving access, day-trip proximity from Brisbane, Hervey Bay, the Gold Coast and Bundaberg, marine-life encounters.

Getting there: Lady Elliot Island is roughly 90 km north-east of Bundaberg, accessible by air.

Located on the southern tip of the Great Barrier Reef, Lady Elliot Island is a haven for those in search of the majestic manta ray. For those who make the journey via a chartered flight from the mainland, a snorkelling or diving encounter with one of the gentle giants is most definitely on the cards. Just make sure you time your visit right – stick to the winter months when they flock to the island in search of cooler water temperatures. Additionally, the coral edges on the island’s western side offer the opportunity to swim alongside dolphins and turtles, with coral gardens visible from the moment you step off the beach. Need more convincing? Excellent year-round water visibility also makes this spot popular amongst families (easy snorkelling), while affordable accommodation at Lady Elliot Island Eco Resort (especially compared to other Great Barrier Reef islands) helps seal the deal.

3. Ribbon Reefs

What it offers: Brightly coloured anemones, the famed Clam Gardens, diverse marine life and crystal-clear conditions.

Getting there: The Ribbon Reefs consist of 10 individual reefs (including Agincourt, outlined above), accessible via a boat trip from Cairns or Port Douglas.

Beginning north of Cairns, and finishing east of Lizard Island, the Ribbon Reefs fringe along a 200-kilometre stretch of the Great Barrier Reef. They are relatively isolated and support a huge range of biodiversity, so a trip anywhere along here will reward you with the likes of huge plate corals, delicate anemones, channels, caves, clams, canyons and shallow coral gardens. It’s just about the clearest portion of the Great Barrier Reef to marvel at. Visitors also choose this place for the famous Cod Hole dive site, home to the massive and friendly potato cod – yet another once-in-a-lifetime photo opp in this neck of the woods. Don’t miss the Clam Gardens dive site, too, where soft corals, a vibrant mecca of fish and, of course, giant clams can be explored.

4. Milln Reef

What it offers: Great beginner diving conditions, high visibility levels on the outer reef, night diving.

Getting there: Day boat tours depart regularly from Cairns and take about 1.5 hours each way.

Boasting a collection of unique dive sites, each varying in scale and opportunity, Milln Reef’s clear, turquoise waters offer a relaxed entry point to the Great Barrier Reef. It’s about 56 kilometres southeast of Cairns and renowned as one of Cairn’s best dive sites. Navigate both shallow and deep dive opportunities, with depths varying from 10 to 20 metres depending on where you drop off. Its Whale Bommie dive site, found in Milln Reef’s Three Sisters cluster on the western side, is the pick for night dives with depths flowing deeper than 20 metres and sea turtles, lobsters, crabs, soft coral and black coral waiting to be discovered.

5. Lizard Island

What it offers: Excellent walk-in beach snorkelling, good access to Cod Hole

Getting there: Chartered flights regularly depart from Cairns and last about an hour each way.

Lizard Island is primarily an island national park, covering 1013 hectares in total. Completely isolated from the rest of the world, it offers one of the Great Barrier Reef’s most northern dive points, plus there are private white-sand beaches and easy snorkelling to help fill your days. More than 150 species of corals and an abundance of marine life can be found in the surrounding waters, while the fringing reef is typically colourful, healthy and vibrant. Divers can reach the likes of Cod Hole and the rest of the Ribbon Reefs via a short boat trip organised by the team behind Lizard Island’s luxurious accommodation offerings, making an overnight stay all too enticing.

6. Hayman Island

What it offers: Exceptional snorkelling suitable for families, good access to the Reefworld pontoon at Hardy Reef.

Getting there: Flights to Hayman Island depart from Hamilton Island airport.

Serving as the closest Whitsundays island to the outer reef, Hayman Island features an array of snorkelling opportunities to keep your entire clan entertained. Blue Pearl Bay, less than 1 kilometre from the island, offers stellar conditions as well as the chance to meet Priscilla, a giant Maori wrasse renowned for interacting with guests. For those wanting more, journey about an hour to Reefworld, located at Hardy Reef, for more than 1,400 species of brightly hued coral plus clownfish, rays and a friendly 2-metre-long groper named George who patrols the area.

7. S.S. Yongala Wreck

What it offers: Intermediate to advanced diving conditions, historical insight and ample marine life.

Getting there: 30-minute boat trips depart from Ayr, near Townsville, but you can also get there via boat from Townsville, which takes three hours each way.

A mysterious and historically significant dive site teeming with marine life, the S.S. Yongala wreck is considered one of the world’s best dive sites. Sinking thanks to a cyclone in 1911, the S.S. Yongala’s structure can still be discovered — almost 75 per cent of the vessel remains intact. The 110 metre-long wreckage is covered with colourful coral and sponges, which have evolved into a magnificent artificial reef and haven for diverse marine life. Fishing and penetration diving bans have upped fish numbers and prevented corrosion, allowing both hard and soft coral to thrive alongside super-sized marine life.

8. Flynn Reef

What it offers: Swim-through coral fields, good beginner snorkelling and diving conditions, high chances for sea turtle spotting.

Getting there: 90-minute boat trips frequently depart from Cairns.

It’s easy to see why visitors from all over the world are drawn to Flynn Reef. Featuring expansive fields of hard coral and plenty of marine life, the underwater hot spot is what Great Barrier Reef postcards are made of. You’ll find it roughly 60 kilometres east of Cairns, sitting pretty as one of the closest reefs to the continental shelf and the Pacific Ocean. Once you’re there, navigate schools of clownfish, batfish, trout, cod, fusiliers, butterflyfish and angelfish along your journey and keep your eye out for sea turtles (including the prevalent green sea turtle), grey reef sharks, moray eels, octopus, lionfish, barracuda and nudibranchs.

Discover the best Great Barrier Reef tours

From the moment you arrive in Moreton Bay, stunning natural vistas, fresh and tasty dining, history and more invite you to stay and play.

Untouched national park, mirror-like lagoons and endless stretches of beaches all make Moreton Bay experiences feel like you’ve stumbled across a secret Queenslanders collectively vowed not to tell. Yet it’s easily accessible. Explore further and discover hinterland farms, ancient rainforest, fresh seafood and more: there’s something on offer for every pace, interest and generation.

Just 20 minutes from Brisbane Airport, it’s hard to believe how underrated this Queensland getaway is. Here’s your ultimate guide to rediscover play with unmissable experiences in Moreton Bay.

1. G’Day Adventure Tours, Bribie Island

G’Day Adventure Tours’ Sea to Table Experience should be your first agenda item in Moreton Bay. Take a 4WD journey through the sandy tracks of Bribie Island’s beaches to the still, glassy waters of the island’s lagoons. Glide over perfect replicas of paperbarks and fluffy blue clouds mirrored in the lagoon waters in your kayak. Listen as native birdsong echoes around you.

Then, it’s on to Fort Bribie. During the Second World War, these concrete bunkers – now slowly being enveloped by the dunes – were the last line of defence for Moreton Bay.

End the day with a sun-dappled beach picnic of locally caught Queensland prawns and famous Moreton Bay bugs. As you head home, watch the dolphins playfully dart in and out of the surf.

2. Morgan’s Seafood at Scarborough

Right on the Scarborough Boat Harbour, you’ll find Morgan’s Seafood . Between the luxury yachts, you’ll also spot trawlers and fishermen delivering their day’s catch right to Morgan’s. The family-owned and operated spot is one of the best places to try the region’s eponymous Moreton Bay bug. Or, sample more of the area’s direct-from-the-boat seafood fresh at their oyster and sushi bar. If you’re lucky, your visit might coincide with a day they’ve caught tuna.

Picture fish caught that day, prepared and then served to you as fresh sashimi as the sun sets over the unique silhouette of the Glasshouse Mountains.

3. Woorim Beach, Bribie Island

On Bribie’s eastern coastline, you’ll find Woorim Beach : aka the closest surf beach to Brisbane. Find a place on the sand by the patrolled area or wander further south to find a quiet spot and while the day away between the shaded dunes, the pages of your book and the peaceful sound of rolling waves.

Ask any local where to grab lunch, and they’ll direct you to Bribie Island Surf Club Bistro . Tuck into a fresh, local seafood platter, just metres from the beach.

4. D’Aguilar National Park

D’Aguilar National Park is a 40,000-hectare slice of greenery that stretches from urban Brisbane right up to Woodford (home of the Woodford Folk Festival). The vast expanse of park is home to ancient rainforests, eucalypt forests and shaded swimming spots hidden within gorges and under waterfalls. The area is significant for the Jinibara and Turrbal people, with ceremonial bora rings and dreaming trails all found within the park.

Carve out some time in your itinerary to explore the park’s many trails. The Maiala day-use area is the perfect starting point for walks for all levels of ability.

5. Arcade Wine Bar

Opposite the Redcliffe Jetty and down a laneway, you’ll find an unassuming wine bar. Venture inside and quickly fall in love with Arcade Wine Bar , one of the region’s most beloved local haunts.

Owners Danilo and Matt have a combined 50 years of sommelier experience, which they have poured into the menu, styling and wine list. More than just a hole-in-the-wall wine bar, Arcade Wine is an enoteca (a wine repository), whose walls are lined with bottles upon bottles of Italian wine varietals from every corner of Italy.

Settle in with a wine and work your way through the menu inspired by Danilo’s native Italy: traditional meatballs, their quick-to-sell-out terrine, or a selection of Italian cheeses, charcuterie and arancini.

6. Wamuran & Loop Rail Trail

Away from the ocean, tucked in the hinterland, is the Wamuran & Loop Rail Trail . Perfect for cyclists or walkers, the trail was built to showcase the history of the Caboolture to Kilcoy rail corridor (last operating in 1964) and makes for the perfect family day out. The trail runs for 10.5km and connects Wamuran and Caboolture via an accessible path.

Pass through former railroad, bridges and shaded bushland as you cut from A to B. Plus, visit in winter for a detour along the way to one of the many pick-your-own strawberry farms.

7. Farm Visits

Beaches, mountains and history make an enticing combination. But Moreton Bay also brings hinterland, family-friendly farms to the table. Trevena Glen is one of the area’s most loved, with bunnies, ponies, sheep, alpacas (and more) available to visit for the kids. For the adults, book a horse-riding session and be treated to a grazing platter as you watch the sun set over the mountains of D’Aguilar National Park.

At White Ridge Farm , find camels, putt-putt, train and tractor rides and all kinds of animals. The entire farm is paved, making it accessible for all.

8. Miss Sprinkles

Miss Sprinkles Gelato moreton bay — Pick your scoop at Miss Sprinkles Gelato.

An ice cream at the beach is one of life’s most perfect pleasures. While in town, stop by Miss Sprinkles for the locals’ pick of homemade gelato on the Scarborough foreshore.

The gelato here is made the authentic Italian way and scooped up just across from the beach. Or, settle in at their kitschy pink wooden tables for traditional gelato in the sunshine. Aside from the homemade gelato, you’ll also find tarts, pies and even doggie gelato.
