Meet the site
Sandringham's breakwater is a piece of maritime recycling. When the yacht harbour was built and extended through the twentieth century, redundant hulls were sunk to form and reinforce the wall, among them the cable-laying steamer Francis Henty, whose remains lie in 3-5 m as part of the structure, and the J-class submarine HMAS J7, scuttled in 1930 and later incorporated into the harbour moorings just north of the breakwater. The dive is a shallow wander along a wall of boulders and old iron in 1-6 m, with more holes, plates and ledges than any natural reef on this stretch of coast, and consequently a lot of fish: leatherjackets, moonlighters, zebrafish, old wives, blennies, wrasse, cardinalfish in the shadows, sea stars, urchins and nudibranchs on the rock, and octopus, cuttlefish and dumpling squid at night. Rays and flathead sit on the sand at the base and juvenile snapper school around the wall in summer. It is a regular night-dive venue because the harbour precinct is lit, the pier gives an easy entry and the water inside the wall is calm in almost any wind. The trade-off is boat traffic: the harbour is home to one of the biggest yacht clubs in the state and the fairway is busy, so divers stay on the breakwater and out of the channel. For an easy, structure-rich dive with a bit of history in the southern bayside suburbs it is hard to beat, and the J7 is there for anyone wanting to extend the swim.
