Port Campbell Bay Reef is a sheltered shore dive on Victoria's Shipwreck Coast, with the reef wall starting from the beach and an old river bed alongside it. The western wall carries marine growth that shelters fish, crayfish, and invertebrates, and the bay also gives a simple snorkel-friendly entry when conditions are calm. It is tide- and swell-sensitive, so low-tide, low-swell windows work best. Boats cross the area, so a flag and float are part of normal planning.
