Meet the site
Moonta Bay is the seaside end of the historic copper-mining town of Moonta, and its jetty is a quieter alternative to Port Hughes, three kilometres to the south. The Dive Shack notes its unusual L-shaped structure and describes it as a popular fishing spot where fish visits are sparse – garfish, tommy ruff and squid – and where divers must watch for fishing line. The jetty stands over sand and seagrass in shallow water, typically 3-5 m at the head. The piles carry sponges, ascidians and algae, and patient divers find nudibranchs, crabs, small octopus and the occasional seahorse. Southern calamari are drawn to the jetty lights at night, and the seagrass fringes shelter juvenile whiting, garfish and pipefish. Blue swimmer crabs are common in summer. It lacks the density of growth and critters that makes Port Hughes famous, and heavy fishing pressure means lines and hooks are a constant presence. Its advantages are its easy access, the family-friendly foreshore and the chance of a quiet dive when Port Hughes is busy. For most divers Moonta Bay is a secondary site – worth a dive if you are staying in town or want to add another Copper Coast jetty to your log, but not a priority. Snorkellers enjoy the shallow inner section in summer. Its visibility depends, like all Copper Coast jetties, on the wind having some east in it. Night dives here are more rewarding than day dives: squid gather under the lights, and crabs and octopus emerge from the seagrass edge. Combine it with Port Hughes for a relaxed two-jetty day on the Copper Coast.
