Sea Turtle Australia November – Encounter Guide & Best Sites

November-March is sea turtle nesting season on the Queensland coast. Mon Repos has the largest loggerhead turtle rookery in the South Pacific.

Encounter overview

Diving or snorkelling with sea turtles in Australia during November is peak season, with an encounter probability of approximately 90% under normal conditions. Sea turtles have been navigating the world’s oceans for 100 million years. Hovering alongside one at a cleaning station or watching it graze on seagrass feels like a direct connection to deep time.

Best sites

• Mon Repos (Queensland)
• Lady Elliot Island
• Heron Island

What to expect

Green turtles (Chelonia mydas) graze on seagrass and algae; hawksbills (Eretmochelys imbricata) feed on sponges and invertebrates. Both species use cleaning stations on coral reefs. Nesting females return to the same beaches every 2-5 years.

Water conditions in November

Water temperature in Australia typically ranges 18-29°C (location-dependent). Visibility at Mon Repos (Queensland) in November is generally good; check local liveaboard or dive operator reports the week of your trip for specific conditions. Reef, liveaboard, shore dive is the primary dive style in Australia.

Practical tips

Never ride or touch a turtle – it burns energy they need for migration. Shine lights away from eyes. If near a nesting beach at night, use red-filtered torches and keep noise minimal. Turtles at cleaning stations will linger for 15-20 minutes.

Getting there
