Eyre Peninsula, SA
Tumby Bay Jetty sits on the Spencer Gulf coast of the eastern Eyre Peninsula, 45 km north of Port Lincoln. It is one of South Australia's classic shore-entry jetty dives, with a resident leafy seadragon colony on the pylons and a steady catalogue of stingrays, seamoths, pipefish and nudibranchs around the structure. The dive is shallow, calm, and well-suited to Open Water divers with patient observation skills. There is no dive shop in town; bring your own kit or hire from Port Lincoln.
