HOOKAH DIVING
Hookah diving systems, also known as Surface Supply Diving Systems, provide a lightweight, low-hassle alternative to traditional scuba gear. The quality hookah dive equipment and hookah accessories available from The Scuba Doctor Dive Shop ensure recreational and commercial divers can get the most out of their surface-supplied air equipment.
Please read Introduction to Hookah Diving for more information about things you need to consider with a hookah diving setup.
We strongly recommend that all Hookah divers take an Open Water Scuba Diving course and become a certified diver. All of the safety precautions that apply to scuba diving also apply to hookah diving. You need to learn and understand things like decompression stops, how to use compressed air and dive computers, and other safety factors. Decompression sickness (DCS), commonly called 'the bends', happens when a diver comes to the surface too quickly. It's a serious health and safety issue and can happen with hookah diving. You should also read books on the subject of underwater diving safety and study them thoroughly. This will further familiarise you with the rules of the deep.
Lonsdale Rock
Bommie Dive | 
Boat access
Depth: 6 m (20 ft) to 15 m (49 ft)
The position of Lonsdale Rock is discernible by the oily appearance of the water due to kelp growing on it.
Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait before diving or snorkelling this site.
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.
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.

Wathaurong (Wadda-Warrung) country
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.
