A boat dive around a protected island 1.4 km off the coast near Lake Munmorah, over a sandy bottom broken by weed and rocky outcrops in less than 20 m. The shallows support blue groper, Port Jackson sharks, stingrays and cuttlefish, with ocean wobbegongs tucked into the rock and macro life on the weed.

The dive

Bird Island sits 1.4 km off the coast in the Tasman Sea, and the dive works the shallow water around it: a sandy bottom with rocky outcrops and patches of weed, all in less than 20 m. The outcrops are the route, so the dive moves from one rock area to the next and crosses the open sand between them rather than following a wall or a fixed line.

Stingrays lie on the sand between the rocks, and ocean wobbegongs are tucked into the rock areas, so approach each outcrop slowly and look under the ledges before you settle. The shallow waters around the island also support blue groper, Port Jackson sharks and cuttlefish. The rock and weed sections carry the macro life, so the second half of the dive is best spent slowly over one good patch rather than covering ground.
