Port Phillip is the entrance to Australia's busiest port and is one of Victoria's most popular recreational destinations.
Every year millions of people enjoy its vast coastline, world-class swimming beaches and coastal parks. An entirely different perspective however is available to those who explore Port Phillip by boat. Island, shipwrecks and marine reserves dot Port Phillip, while scuba diving and fishing reveal the colourful diversity of Port Phillip's marine life.
