Advanced Open Water Rated Crayfish Dive Site Deep Rated Inside Port Phillip Reef Dive Site Slack Water Subject to Shipping Technical Rated

Depth: 24 metres (79 feet) to 60 metres (197 feet)

This is a rugged piece of wall dive in the very middle of the main shipping channel inside Port Philip. Diving is only possible as a slack water dive at the end of the Ebb or outgoing tide and even then only if no shipping is due through the heads for the next three hours.

The top of the wall is 24 metres and the wall itself runs East to West at this point and drops off to the South down to 60 metres. Features of this site include huge caves, swim-through and vertical cracks.

Divers have the opportunity to catch crayfish (Southern Rock Lobster) at this dive site. Remember your catch bag, current Victorian Recreational Fishing Licence, rock lobster measure, and cray tags. Please abide by all current fishing regulations if you intend to catch crays. See How To Catch Crayfish for practical cray hunting advice from The Scuba Doctor.

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.
