Port Campbell Jetty is a shore-access pier dive on the eastern side of Port Campbell Bay, with an easy route off the jetty or from the beach and a shallow reef line beneath the pylons. The jetty structure and nearby sand hold anemones, juvenile fish, rays, and other shelter-loving life, while the bay itself is calmer than the exposed coast around it. It is still tide- and swell-sensitive, and the site can turn surgey fast when the Southern Ocean builds. Treat it as a low-swell, safety-aware day dive rather than a guaranteed casual swim.
