The Tuggerah Wreck

Lying in 46 metres of water off the Royal National Park, the Tuggerah is a favourite among Sydney tech divers. This 180-foot coastal steamer sank during a storm in 1919 while carrying coal from the Illawarra region. Today, it rests on its port side, largely intact, and teeming with marine life. Divers are treated to schools of bullseyes, large wobbegongs, and even the occasional kingfish circling the wreck. With its propeller still in place and plenty of structure to explore, the Tuggerah is a fantastic dive that offers both historical interest and challenging depth—making it a true technical diver’s delight.

The Kelloe Wreck

The SS Kelloe lies in about 48 metres of water off Botany Bay. This iron-hulled collier went down in 1902 after a collision with another steamer. Though scattered, the wreck site features impressive debris fields, including the boiler, engine components, and other large structural elements. It’s a dive that rewards careful navigation and exploration. Marine growth has overtaken the wreck, attracting cuttlefish, port Jackson sharks, and a wide variety of invertebrates. The Kelloe is less dived than the Tuggerah, adding to its appeal as a slightly more remote and mysterious site for seasoned tech divers.
