North Wall Corner is is an amazing dive, situated at the Northern end of the Lonsdale Wall in Port Phillip. Lonsdale Wall runs South to North, and at this point it turns and runs West to East. At North Wall Corner the current has scoured quite a deep area. The walls tower vertically here with amazing splits and overhangs sheltering an amazing variety of soft coral and sponges.

The top of the wall is around 19 metres in depth and slopes down to the bottom at 66 metres. Thus North Wall Corner is a dive for the experienced diver as the maximum depth of 66 metres is out of range for the average diver.

As you descend there is a maze of over-hangs, caves, and smaller crevices that support a vast array of marine life. These crevices are the home of many blue-devils and blue groper as well as an endless cross-section of temperate invertebrates.

It must be noted that part of this site lies within the Port Phillip Heads Marine National Park, whilst the remainder lies in the shipping channel. It is illegal to anchor in a shipping channel, so divers must be aware of any shipping movements and plan the dive accordingly.

Generally this dive is done on Slack Water at the end of the Flood so that it's at its clearest. For this dive it is best to swim along the East West wall first and then return onto the North South wall before the current picks up.

Port Phillip Heads Marine National Park

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.

Thirty-one of the 120 shipwrecks known to have occurred within a 10 nautical mile radius of Port Phillip Heads are thought to be within the Port Phillip Heads Marine National Park in Point Lonsdale and Point Nepean.

Aboriginal tradition indicates that the Bellarine Peninsula side of the Port Phillip Heads Marine National Park is part of Country of the Wathaurung people, and the Mornington Peninsula side, including Mud Islands, is part of Country of the Boon Wurrung people.

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.
