The Best Snorkelling Spots in Australia: A State-by-State Guide

Australia has some of the finest snorkelling in the world. Two of the planet's great reef systems — Ningaloo and the Great Barrier Reef — sit entirely within Australian waters, and beyond them, the country has hundreds of accessible snorkelling locations from tropical rock platforms to temperate kelp forests. Here's a guide to the best of them.

What You Need to Snorkel

Snorkelling requires almost no gear or experience. The basic kit:

Mask — the most important piece of equipment. A mask that fits well (holds suction against your face without straps) makes the entire experience better. Try before you buy; rental masks at popular snorkel sites are often ill-fitting.
Snorkel — a simple J-shaped snorkel is fine for surface snorkelling. Dry-top snorkels (with a valve that seals when submerged) are easier for beginners.
Fins — not strictly necessary in calm, shallow reef areas but useful for covering distance and managing mild current. Short-blade fins are the most practical for beach entry.
Rash vest or wetsuit — a UPF rash vest provides sun protection on your back (one of the most UV-exposed surfaces during snorkelling) and some thermal comfort in cooler water.

Most popular snorkelling destinations in Australia have hire available if you don't own equipment.

Western Australia

Turquoise Bay, Ningaloo Reef

The standout snorkelling experience in Australia. Ningaloo Reef runs parallel to the WA coast for over 300 kilometres, and at Turquoise Bay the reef begins just metres from the beach — no boat required. The drift snorkel is the highlight: enter the water at the southern end of the bay and let a gentle current carry you north over the reef at walking pace while you watch the sea life below.

Coral cover is exceptional — large table corals, staghorns, and brain corals — with turtles, reef sharks, rays, and hundreds of species of fish as regular companions. The water is warm (25–28°C from October to April) and clear. One of the genuinely world-class snorkelling experiences.

Best time: April to October for the calmest conditions. March to July for whale shark season.

Coral Bay, Ningaloo

South of Exmouth, Coral Bay is a small town with reef accessible directly from the beach — no drift required. The bay is calmer than Turquoise Bay and excellent for beginners and families. Manta rays are resident here year-round, and manta ray snorkelling tours operate daily.

Best time: Year-round; manta rays most reliable March to May.

Mettam's Pool, Trigg, Perth

For Perth-based snorkelling without a long drive, Mettam's Pool — a natural rock pool enclosure 15 minutes north of the city — offers accessible reef snorkelling with good fish life, particularly in the morning before the wind comes up.

Queensland

Great Barrier Reef — Cairns and Port Douglas

The world's largest coral reef system, stretching 2,300 kilometres along the Queensland coast. Day trips from Cairns and Port Douglas reach the outer reef in 90 minutes to two hours by fast catamaran. The outer reef platforms — Agincourt Reef, Norman Reef, Flynn Reef — offer snorkelling in water of extraordinary clarity with exceptional coral and fish diversity.

Best time: June to October — the dry season, with calmer seas and better visibility. Stinger suits are recommended year-round; mandatory from November to April on most tour boats.

Lady Elliot Island, Southern Great Barrier Reef

A coral cay at the southern tip of the Great Barrier Reef, accessible by light aircraft from Bundaberg or Hervey Bay. The snorkelling here is among the best on the reef — extensive coral gardens immediately accessible from the beach, with high densities of manta rays, turtles, reef sharks, and diverse fish life. A smaller, quieter alternative to the busy Cairns reef operations.

Best time: Year-round; mantas most reliable December to April.

Heron Island, Southern Great Barrier Reef

Similar to Lady Elliot — a coral cay with reef directly accessible from the beach. Heron is famous for its turtle nesting (November to March) and the density of marine life directly off the island's shore. The Heron Bommie, a large coral pinnacle 10 minutes by dinghy, is one of the best dive and snorkel sites on the southern reef.

Whitsundays — Hook Island and Border Island

Day trips from Airlie Beach reach several excellent snorkel sites around the outer Whitsunday Islands. Hook Island has a large, protected lagoon with good coral and fish life accessible from the beach. Border Island is less visited with cleaner coral. Both are significantly better for snorkelling than the famous Whitehaven Beach, which is primarily a sand destination.

Best time: May to November.

New South Wales

Shelly Beach, Manly

A marine protected area in a sheltered cove adjacent to Manly Beach. The protection means fish density and diversity are both noticeably higher than at comparable unprotected sites. Wobbegong sharks rest on the sandy bottom; blue gropers, luderick, and drummer are common. Entry directly from the beach, no boat required.

Jervis Bay — Murrays Beach and Caves Beach

The clear, protected water of Jervis Bay offers excellent snorkelling at several locations. Murrays Beach in the Booderee National Park section has a reef platform accessible from the shore with good fish and invertebrate life. Caves Beach further into the park has underwater caves and swimthroughs suitable for confident snorkellers.

Julian Rocks, Byron Bay

A marine reserve 2.5 kilometres offshore from Byron Bay, accessible by boat from the Main Beach. Julian Rocks sits at the convergence of tropical and temperate water currents, creating unusual biodiversity — leopard sharks, grey nurse sharks, manta rays, and tropical reef fish all coexist here. Snorkelling tours and dive charters operate from Byron Bay year-round.

Best time: December to May for the warmest water and best visibility.

South Australia

Second Valley, Fleurieu Peninsula

A sheltered cove with a limestone reef accessible from the beach. Cold water (14–18°C year-round) rewards those who bother with a wetsuit — the reef life, including leafy sea dragons, is excellent. Leafy sea dragons are unique to southern Australian waters and are among the most extraordinary creatures visible to snorkellers anywhere in the world.

Rapid Bay Jetty, Fleurieu Peninsula

The old jetty pylons at Rapid Bay are encrusted with invertebrates and attract large numbers of leafy sea dragons — one of the most reliably good leafy sea dragon snorkel sites in Australia. A wetsuit is essential.

Victoria

Sorrento, Mornington Peninsula

The rock platforms and shallow reef around Sorrento Back Beach and the Sorrento pier area offer good snorkelling in Victorian conditions. Weedy sea dragons (related to but distinct from leafy sea dragons) are commonly found here. Wetsuit essential — water temperature ranges from 12°C in winter to 20°C in late summer.

Wilsons Promontory — Waterloo Bay

Accessible only via a multi-day hike or by boat, the remote beaches of Wilsons Promontory have excellent snorkelling in protected marine national park waters. Waterloo Bay and Refuge Cove are the standout locations. The isolation means the marine life here is largely undisturbed.

Tasmania

Fortescue Bay, Tasman Peninsula

Cold, gin-clear water, kelp forests, and excellent invertebrate and fish life. Accessible from the Fortescue Bay campground in the Tasman National Park. A 5mm wetsuit is essential year-round; a hood and gloves are advisable in winter. The dramatic dolerite sea cliffs above make for an unusual snorkelling backdrop.

Tips for Better Snorkelling in Australia

Anti-fog your mask. A fogging mask ruins snorkelling. Rub a small amount of toothpaste or dedicated anti-fog gel on the inside of the lens before you enter, rinse lightly, and it will stay clear for hours.

Breathe slowly. Slow, relaxed breathing extends your time in the water and reduces the chance of water entering the snorkel. Panic breathing is the most common beginner problem.

Float, don't kick. At reef sites, excessive kicking stirs up sediment and disturbs marine life. The best snorkelling is slow and still — float and let the sea life come to you.

Never touch the coral. Coral is alive and extremely fragile. Physical contact — even accidental — damages polyps and introduces bacteria. Maintain depth and don't use coral for support.

Wear reef-safe sunscreen. Oxybenzone and octinoxate — common sunscreen ingredients — are toxic to coral. At reef snorkelling sites, use mineral (zinc oxide or titanium dioxide) sunscreen or cover up with a rash vest rather than relying on chemical sunscreen.

After a morning in the water, your skin needs recovery. UV reflects intensely off the ocean surface during snorkelling — more than most people realise. Apply after sun oil when you're done for the day, and come back to a proper base with the XO Beach Blanket set up under shade while you dry off.
