Australia’s Most Underrated Wilderness Peninsula
The Eyre Peninsula is a triangular wedge of South Australia bounded by the Spencer Gulf, the Great Australian Bight, and the Gawler Ranges — and one of the most spectacular, least-visited regions in the country. Port Lincoln is the seafood capital of Australia with the Southern Hemisphere’s largest fishing fleet. At Coffin Bay, you wade into waist-deep water for oysters so good they’re sold at a premium worldwide. At Baird Bay you swim with wild sea lions in the open ocean. At Neptune Islands, great white sharks circle your cage. And through it all runs over 2,000km of wild coastline barely changed since Matthew Flinders charted it in 1802.
✈️ Getting There

Port Lincoln is 680km from Adelaide — about 7 hours of driving. For focused 3–5 day trips to the southern peninsula, flying with Rex Airlines (45 min, ~$150–250 return) saves a full day each way. For longer road trips exploring the whole peninsula coast-to-coast, driving via Port Augusta allows stops at the giant cuttlefish at Whyalla.
🐩 Port Lincoln — Australia’s Seafood Capital
Port Lincoln is home to the Southern Hemisphere’s largest commercial fishing fleet — trawlers, tuna farms, crayfish boats, and aquaculture operations supplying premium seafood to restaurants across Australia and internationally. The city is the departure point for two of Australia’s most extraordinary wildlife experiences.
- Swimming with Southern Bluefin TunaPort Lincoln’s tuna farms hold large schools of southern bluefin tuna in sea cages offshore. Operators offer snorkelling or diving in the water alongside them — fast, powerful fish at very close quarters. Approximately $95–195 per person.
- Shark Cage Diving — Neptune IslandsPort Lincoln is the world’s most reliable departure point for great white shark cage diving. The Neptune Islands (90 min offshore) host a consistent great white population year-round. No diving experience required. Full-day tours approximately $500–700 per person.
- The Fresh Fish PlaceFactory-direct seafood market — King George whiting, snapper, Coffin Bay oysters, Boston Bay mussels, all daily-fresh at prices unavailable elsewhere.
🦪 Coffin Bay — The World’s Best Oysters
Coffin Bay oysters are grown in pristine, cold, nutrient-rich protected waters and considered among the finest in the world — a clean, intensely ocean-fresh flavour impossible to replicate from tank or transit. The best experience is a guided farm tour — you wade into waist-deep water with a local farmer, learn how Pacific and Angasi oysters are cultivated from seed to harvest, shuck your own, and eat them fresh from the rack. Tours cost approximately $80–120 per person. You can also buy a dozen directly from farm shops for as little as $10–15. Coffin Bay National Park (50km west of Port Lincoln) is a wild landscape of sand dunes, isolated beaches, and exceptional wildlife — a 4WD is needed for the best areas.
🦕 Baird Bay — Swimming with Sea Lions
Baird Bay is a small fishing village on the northwest coast of the Eyre Peninsula where Ocean Eco Tours runs one of Australia’s most extraordinary wildlife encounters: swimming with wild Australian sea lions and bottlenose dolphins in the open ocean. Sea lions are fast, curious, and apparently delighted by humans — they spin around swimmers, come face-to-face, investigate snorkel masks, and play entirely on their own terms. Every moment is natural and genuine.
Tour details: Half-day tours approximately $200 per adult / $100 per child. Wet suits provided. You must be able to swim. Best season is September through May. Book well ahead — numbers are limited. Baird Bay is approximately 530km from Port Lincoln.
