Located just inside the heads of Port Philip Bay on the Lonsdale Wall system, The Mall is part of the underwater canyon formed by the old Yarra River as it flowed out through the plains carving steep walled edges out of soft rock sides before the sea levels rose and the bay flooded many years ago. An almost vertical drop characterizes the site with overhangs and ledges and undercuts providing sanctuary to an enormous variety of fish including the spectacular Blue Devils, Leather Jackets, Magpie Morwongs, Hula Fish, Old Wives plus Crayfish and Cuttlefish. At least four different Nudibranchs and Seastars can be found here if you look closely.

This site lies in the Port Phillip Heads Marine National Park. The park is made up of six separate marine areas around the southern end of Port Phillip: Swan Bay, Mud Islands, Point Lonsdale, Point Nepean, Popes Eye, and Portsea Hole.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
