South Australia’s Adventure Coast

The Eyre Peninsula is where South Australia meets the Southern Ocean — 2,500 kilometres of pristine coastline stretching from the sheltered waters of Spencer Gulf to the thundering swells of the Great Australian Bight. This is a region of extremes: towering sea cliffs and turquoise bays, abundant seafood and vast pastoral stations, cage diving with great white sharks and swimming alongside sea lions. The Eyre Peninsula has earned its reputation as South Australia’s adventure sports capital, but it is also a place of quieter discoveries — coastal walking trails through national parks, seasonal gatherings of giant cuttlefish, and remote beaches where your footprints may be the only ones in the sand.
The region’s five sub-regions — Eastern Eyre, Lower Eyre, West Coast, Far West Coast, and the Gawler Ranges — each offer distinct landscapes and experiences. Port Lincoln, the region’s largest town, is one of Australia’s wealthiest fishing ports, built on the Southern Bluefin tuna industry that also supports cage diving tourism. Whyalla, on the eastern shore of Spencer Gulf, hosts one of the world’s most remarkable marine events — the annual winter aggregation of giant Australian cuttlefish. And Coffin Bay, famous for its oysters, provides the gateway to a national park of wild beauty.
Coastal Walking

Coffin Bay National Park protects some of the Eyre Peninsula’s most spectacular coastal scenery — wild beaches, limestone headlands, and sheltered bays where ospreys nest on sea stacks and dolphins cruise the shallows. The park’s walking trails take you through this landscape, from island hikes accessible at low tide to long beach traverses that connect headlands and hidden coves. The Elliston Coastal Trail, further north along the west coast, follows dramatic cliff-top paths above the Southern Ocean, offering some of the most spectacular coastal walking in South Australia.

Diving with Giant Cuttlefish
Every winter, between May and August, the waters off Whyalla’s Stony Point become the stage for one of the ocean’s most extraordinary events. Hundreds of thousands of giant Australian cuttlefish — the world’s largest cuttlefish species — gather in the shallow rocky reef to mate and spawn. The aggregation is unique globally, occurring nowhere else on Earth at this scale. Divers and snorkellers can enter the water and find themselves surrounded by these remarkable creatures, which display mesmerising patterns of colour and texture as they compete for mates.

The Eyre Peninsula’s trails lead to the edge of the continent — to wild beaches where the Southern Ocean crashes against ancient limestone, to national parks where the coastline belongs to the ospreys and sea lions, and to shallow reefs where giant cuttlefish gather in numbers found nowhere else on Earth. This is South Australia at its most raw and magnificent, a region where the trails are just the beginning of the adventure.
