In recent years, the numbers of southern humpback and southern right whales entering the bay of Port Phillip have shown increases. Unlike in Portland and on Great Ocean Road, Southern Rights in eastern Victorian waters are still critically endangered and in very small numbers; however, presences of cow-calf pairs in the bay in recent years indicate that Port Phillip Bay was possibly once a wintering/calving ground for these whales. They swim very close to shores to take rests in shallow, sheltered waters, sometimes just next to piers in Frankston.
