The Best Turtle Experiences in the Southern Great Barrier Reef

If you love sea turtles, the Southern Great Barrier Reef is one of the world’s most rewarding places to explore. From coral cays teeming with marine life to ranger-led nesting encounters, this region offers unforgettable moments with green, loggerhead and hawksbill turtles.

Here’s your guide to the very best turtle experiences across Heron Island, the Keppel Islands, Lady Elliot Island, and Mon Repos.

Heron Island – Turtles on Your Doorstep

Heron Island is a natural sanctuary where turtles are part of everyday life. The island sits directly on the reef, giving snorkellers and divers instant access to shallow coral gardens, reef edges and sandy flats turtles love.

Why Heron Island Is Special for Turtles

Nesting & Hatching Season:

• Green and loggerhead turtles nest from late October/November to March. Hatchlings begin emerging from January to May.
• Year-round in-water sightings:
• Resident turtles graze on the reef flats and rest among bommies, making encounters common even outside nesting season.

Best Turtle Experiences

• Snorkelling the reef edge: Drift over coral shelves where turtles cruise between cleaning stations and seagrass patches.
• Night-time nesting walks: During nesting season you may spot females coming ashore around high tide.
• Dawn hatchling runs: Early mornings sometimes reveal straggler hatchlings making their dash to the sea.

Access: Heron Island is reached via ferry or seaplane from Gladstone.

Keppel Islands – Easy, Family-Friendly Turtle Encounters

The Keppel Islands, just off Yeppoon near Rockhampton, offer calm, shallow, easily accessible reefs perfect for spotting turtles without boats, deep water or long swim distances.

Why the Keppels Are Great for Turtles

Sheltered fringing reefs create ideal feeding grounds for green turtles. Clear, shallow bays make it easy for snorkellers of all ages to enjoy turtle encounters.

Top Turtle Spots in the Keppels

• Monkey Beach & Shelving Point: Excellent off-the-beach snorkelling with frequent turtle sightings.
• Snorkel safaris: Fast-boat tours from Yeppoon hop between reefs and increase your chances of seeing multiple turtles in one outing.
• Kayak & SUP spotting: Calm mornings let you watch turtles surface to breathe from above the waterline.

Access: Ferries and day tours depart from Keppel Bay Marina (Yeppoon/Rosslyn Bay).

Lady Elliot Island – A Turtle & Manta Ray Wonderland

Renowned for its pristine reef and crystal-clear visibility, Lady Elliot Island is heaven for snorkellers and divers. While manta rays often steal the spotlight, the island is also home to abundant sea turtles.

Why Lady Elliot Island Is Turtle Heaven

• Green and hawksbill turtles are seen year-round across both lagoon and western reef sites.
• Turtle cleaning stations along the reef edge offer relaxed, world-class snorkelling encounters.
• Seasonal turtle talks and guided activities enhance the experience.

Best Turtle Experiences

• Lagoon snorkelling: Shallow and sheltered, perfect for beginners and families.
• Glass-bottom boat & guided snorkels: Learn about turtle behaviour and get help spotting camouflaged individuals.
• Reef-edge snorkel safaris: Confident snorkellers can join trips to sites like Coral Gardens, where turtles mingle with manta rays and reef sharks.

Access: Lady Elliot Island is reached via light aircraft from Bundaberg, Hervey Bay, Brisbane and the Gold Coast.

Mon Repos – The Southern Great Barrier Reef’s Turtle Nursery

Mon Repos Conservation Park, near Bundaberg, hosts the largest concentration of nesting loggerhead turtles on Australia’s east coast. Ranger-led encounters offer intimate, responsible viewing opportunities.

Why Mon Repos Is Unique

It protects the most important loggerhead rookery in the South Pacific. Viewing is strictly controlled to minimise impact on nesting females and hatchlings.

Best Turtle Experiences

• Nesting tours (Nov–Jan): Watch female loggerheads haul ashore, dig nests and lay eggs under carefully managed conditions.
• Hatchling tours (Jan–March): Witness thousands of hatchlings erupt from nests and scramble toward the ocean.
• Mon Repos Turtle Centre: Learn about turtle biology, satellite tracking and conservation programs.

Access: A short drive from Bundaberg, with tours departing from the Turtle Centre.

When to Visit for the Best Turtle Encounters

• Nesting: November–March
• Hatching: January–May
• Best in-water encounters: Year-round, especially in the Keppel Islands, Heron, and Lady Elliot, with calmer conditions in winter and spring.
• For the chance to witness both nesting and hatchlings in the same trip, visit in late January–February.

How to Be a Turtle-Friendly Traveller

• Keep a respectful distance—never chase or touch turtles.
• Move slowly and stay near the surface when snorkelling.
• On nesting beaches, use no lights or red-filtered lights and avoid standing in front of turtles.
• Remove beach obstacles and minimise night lighting.
• Choose eco-friendly operators who actively support turtle conservation.
