Located on the Lonsdale side of Port Phillip Heads, the Lonsdale Wall extends for 1km, therefore providing many different dives. The Wall is characterised by an almost vertical drop. As you descend there is a slight step-out every 6 to 9m and behind each step-out there is a huge overhang which is easy to swim through. These overhangs support an enormous variety of fish, soft corals, sponges and other invertebrate life.
