The Neptune Islands are a remote, boat-based dive site located in the open Southern Ocean. Diving here is conducted within protective cages due to the presence of great white sharks, bronze whaler sharks, and mako sharks. The topography features reef sections ranging from shallow depths down to 21 metres. Divers also encounter New Zealand fur seals and Australian sea lions. While the islands are exposed to strong currents and surf, operations take place in sheltered anchorages. Visibility typically ranges from 15 to 25 metres, though it can fluctuate. Water temperatures vary between 15C and 19C throughout the year. Guided tours are required for all dives.

Visibility can shift dramatically between dives, so do not be discouraged if conditions look murky on arrival as they often clear through the day. The cooler months from May through October tend to bring the most reliable shark activity, so if great whites are your priority those are the months to prioritise.
Access is exclusively via liveaboard or day charter boats departing from the Port Lincoln Marina. The boat journey takes approximately 2.5 to 3 hours.
