Twin Bommies (aka Twin Towers Reef) 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 Heads 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 Port Jackson Shark, or a Southern Rock Lobster (aka Crayfish) or two.

Divers have the opportunity to catch Southern Rock Lobster (aka Crayfish) at this dive site. Remember your catch bag, current Victorian Recreational Fishing Licence, rock lobster measure, and cray tags. Once you get back to the dive boat, or shore, make sure you clip the tail and tag your Crayfish as per Fisheries requirements. 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, plus Melbourne Cray Dives for a list of other crayfish dive sites near Melbourne. For tips on cooking your Crays, please see How To Cook Crayfish.

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.
