Depth: 2 metres (6.6 feet) to 8 metres (26 feet)

Level: Open Water and beyond.

Black Rock Jetty in Half Moon Bay, Port Phillip, is a good site for new divers. Around the Black Rock Jetty are small leather jackets, star fish, gobbleguts and the occasional seahorse.

Half Moon Bay, home to the Black Rock Yacht Club, the Half Moon Bay Lifesaving Club, is the crescent shaped small sandy shallow area to the left of the car park. It is an excellent night dive especially in spring when the phosphorescence is at its brightest. At night you can find octopus, flathead and bull rays. Avoid during a southerly as the area can get quite choppy.

See WillyWeather as a guide for the tide times and the height of the tide.

Also worth a note is the wreck of the HMVS Cerberus warship. Divers are now banned from the wreck as it is too dangerous, so please keep a distance away. The guns from the warship lie on the sandy bottom nearby.

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.
