Swim with the locals

You can swim with sea-lions, dolphins and schools of fish off the coast of South Australia's Eyre Peninsula. The peninsula stretches 1,000 kilometres east to west and 400 kilometres from the Gawler Ranges in the north to Port Lincoln in the south.

Boston Bay Wines on the shore allows visitors to taste its medal-winning reds and whites.

Each Australia Day weekend (Australia Day falls on January 26), Port Lincoln holds the Tunarama Festival. Highlights include the World Record John West Tuna Tossing Championship.

Just over 30 kilometres offshore from Port Lincoln lies aptly-named Dangerous Reef, a breeding area for great white sharks. You can descend among them in a dive cage - if you dare!
