Depth: 2 metres (6.6 feet) to 6 metres (20 feet)

Level: Open Water and beyond.

West of the beach at Williamstown is a small promontory known as 'The Jawbone'. The eastern side of Jawbone is dominated by basalt boulders with encrusting worms and mussels. Numerous sea-stars and crabs inhabit the crevices, while shrimps and small fish dart amongst the weeds.

This site is located within the Jawbone Marine Sanctuary, which is the most northern marine sanctuary in Port Phillip Bay. Jawbone Marine Sanctuary, named after its shape, is located in Williamstown and protects 30ha of coastal waters. The little promontory, west of the beach at Williamstown, has been fenced off from the rest of the world for over 80 years by a coastal rifle range. This forgotten and unspoilt place is now considered a haven for coastal and marine life right next to Melbourne.

Nice site apart from walk down to the beach. In the shallows there is lots of seagrass with pipefish to be found nearly all of the time. Dumpling squid, wollongog bugs, sand octopuses, tiny seahorses, leatherjackets, zebrafish, clingfish and crabs have been spotted here.

More protected than Williamstown Beach Breakwater (Crystals), so a good site to dive instead when the wind is up. There is a wreck not far off shore as well, and there are many spots to dive here in all directions. The further south you go the deeper it gets and there are also colourful corals to be spotted here.

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.
