Meet the site
Port Lincoln is Australia's tuna and seafood capital and the base for the Neptune Islands and sea lion trips, but it also has easy diving right in town. The Marine Life Society describes the town jetty as an easy shore dive in the centre of Port Lincoln, in about 4 m, whose pylons are covered with colourful marine life and which is good for photography by day or night. The piles carry sponges, ascidians, bryozoans and algae in reds, oranges and yellows, and they host the usual jetty cast: nudibranchs, decorator and spider crabs, small octopus, seahorses and pipefish, with leatherjackets, cowfish, magpie perch and schools of tommy ruff and yellowtail. Squid gather under the lights at night, and the sandy bottom holds rays, flathead and the chance of a Port Jackson shark. Boston Bay's sheltered water means it can be dived in most conditions. It is the obvious place for a check-out dive or a night dive for visitors in town for the shark and sea lion tours, and it is popular with locals for training. Kirton Point jetty, a short drive east, offers a deeper reef dive with better visibility, and the scuttled tug Bronzewing lies out in Boston Bay for those with a boat. Air fills and gear hire are available in town, and the jetty's central location means cafes and the foreshore are a few steps away, which makes it a convenient dive for groups with non-diving companions.
