Wall Dive | Boat access
Depth: 12 m (39 ft) to 45 m (148 ft)
Party Point is located on the Lonsdale side of Port Phillip Heads and is a dive site on the Lonsdale Wall which extends for 1 km, therefore providing many different dives. An almost vertical drop characterises the Party Point dive site as the wall extends out to form a large point.
As you descend there is a slight step-out every 6 to 9 metres, and behind each step-out, there is a huge overhang, which is easy to swim through. These overhangs support an enormous variety of fish including the spectacular Southern Blue Devil, Southern Rock Lobster (aka Crayfish), soft corals, sponges and other invertebrate life.
Party Point is a slack water dive, that is not in the shipping channel. Care still must be taken to ensure all divers are aware of the state of the tide, and their exit strategy at the end of slack water. While technical divers can reach a depth of 45 metres at Party Point, there is plenty for an Open Water rated diver to see down to 18 metres, and for an Advanced Open Water rated diver to see down to 30 metres.
The Rip & Tides Warning: Always keep an eye on sea conditions throughout any shore or boat dive within "The Rip" (aka "The Heads"). This is a dangerous stretch of water, where Bass Straight meets Port Phillip, which has claimed many ships and lives. Please read the warnings on the web page diving-the-rip before diving or snorkelling this site.
This dive site is one of many on Lonsdale Wall, located just inside The Heads on the Lonsdale side of Port Philip — one of Australia's premier dive locations. Lonsdale Wall is one side of an underwater canyon formed by the old Yarra River as it flowed out to sea through the plains, carving steep-walled edges out of soft rock sides. Between the end of the last Ice Age around 8000 BCE and around 6000 BCE, the sea-level rose to drown what was then the lower reaches of the Yarra River. Thus the canyon formed by the river near what is now The Heads, or The Rip, was flooded creating the Lonsdale Wall, North Wall and Nepean Wall areas. Lonsdale Wall extends for one kilometre, providing many spectacular dive sites. An almost vertical drop characterises Lonsdale Wall with the wall starting as shallow as 8 m (26 ft) metres deep in places and sometimes dropping down to well over 60 m (197 ft) deep.

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.

Traditional Owners — This dive site is in the traditional Country of the Wathaurong (Wadda-Warrung) people of the Kulin Nation. This truly ancient Country includes the coastline of Port Phillip, from the Werribee River in the north-east, the Bellarine Peninsula, and down to Cape Otway in the south-west. We wish to acknowledge the Wathaurong as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

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.
