Frankton Pier

Frankston Pier is a popular beginner-friendly shore dive located on the eastern shore of Port Phillip Bay in Melbourne's southeastern suburbs, Victoria, Australia. With a maximum depth of just 6 meters, this accessible pier dive is one of the most convenient and rewarding places to explore temperate marine life in the greater Melbourne area. The pier's wooden and concrete pylons form a linear reef structure that extends several hundred meters into the bay, creating a protected corridor of habitat that supports a remarkable concentration of marine life for such a shallow, suburban location. The pylons act as vertical gardens, with each one hosting its own community of encrusting organisms from the waterline to the sandy bottom. The marine life at Frankston Pier is surprisingly diverse and provides excellent opportunities for macro photography. Colorful sponges, ascidians, and bryozoans coat the pylons in vivid patches of orange, purple, and green. Nudibranchs of various species graze on the growth, their impossibly bright colors making them favorite subjects for underwater photographers. Seahorses and pipefish cling to the structure and the nearby seagrass beds, while blue-ringed octopus can occasionally be spotted in their tiny dens among the debris on the sandy bottom. Larger residents include various species of leatherjacket that hover around the pylons, curious banjo sharks resting on the sand, and schools of trevally that patrol the pier's length. During the cooler months, the pier may attract spider crabs in large aggregations - a phenomenon unique to Port Phillip Bay that creates unforgettable diving when it occurs. The beginner-friendly conditions make Frankston an ideal training and confidence-building site. Depths are minimal, currents are negligible within the bay, and shore access eliminates the need for boat logistics. The pier provides a natural navigation reference, making it nearly impossible to become disoriented. Water temperatures in Port Phillip Bay range from about 10 degrees in winter to 21 degrees in summer. Visibility varies from 1 to 8 meters depending on conditions. Despite the sometimes limited visibility, the concentration of life within arm's reach ensures there is always something fascinating to observe. Frankston Pier is proof that exceptional diving can be found in the most accessible places.
