Twin Bommies

Bommie DiveBommie Dive | Boat access

Crayfish Dive Site Open Water Rated Outside Port Phillip Reef Dive Site

Depth: 12 metres (39 feet) to 18 metres (59 feet)

Twin Bommies is exactly as its name would suggest, two large rock Bommies standing up from the 18 metre seabed just off Point Lonsdale outside of Port Phillip in Bass Strait. The Bommies have a large community of fish life and are covered in bright soft corals and sponges. A great dive with lots of photo opportunities, not to mention the odd Crayfish or two.

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.
