Diving in Eyre Peninsula
Port Lincoln is the base for Australia's only great white shark cage diving at the Neptune Islands, and for sea lion swims at Hopkins Island and Baird Bay. Around the peninsula's coast are the Port Lincoln jetties, Tumby Bay, the wreck of the Fides and a great deal of clear, cold, unvisited reef.

Record your trip questions →Questions, answered
How do I choose a dive in Eyre Peninsula?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 29 published records are research options, not a list of trips available today. Match the plan to your training, recent experience and the operator’s current requirements.
When should I visit Eyre Peninsula for diving?
Choose dates with a provider who runs the activity you want, then discuss seasonal patterns, recent conditions and alternative itineraries. A generic best-month claim cannot establish the conditions at your exact site or guarantee a wildlife encounter.
Can I use these maps to enter or navigate a dive site?
No. Recorded and approximate map positions support orientation only. Confirm the exact access, permissions, meeting point and route with the responsible local provider or manager.
