Snorkels
Although there is an abundance of snorkels on the market to choose from, we believe that you get what you pay for. Some cheap snorkels, plus budget mask and snorkel sets, offer snorkels which are not sealed correctly and therefore when bent and in use the snorkel lets in water not through the top, but through the centre. You won't find any of those here.
Diving Snorkels - The snorkels here are for scuba divers. Thus they naturally drop away from the diver's face because most of the time the diver will have a 2nd stage regulator in their mouth, not the snorkel mouthpiece. When the diver does use the snorkel the mouthpiece is bent up and into the mouth. This does place some additional pressure on the jaw and mouth compared to a snorkel for snorkellers that is designed to make this easier.
Snorkelling Snorkels - Some snorkels are designed more for snorkeling, rather than scuba diving. This means the snorkel is shaped so that the snorkel mouthpiece naturally comes close to the mouth. Thus the snorkeller has less pressure on their jaw and mouth. These snorkels are in our Snorkelling Snorkels section.
Note: For child and junior sized snorkels, please look at our Kids Corner.

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.
