Encounter overview

Diving or snorkelling with sea turtles in Australia during March is high season, with an encounter probability of approximately 80% under normal conditions.

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 March

Water temperature in Australia typically ranges 18-29°C (location-dependent). Visibility at Lady Elliot Island in March 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.
