The Wreck Today
This is the most recently discovered of the four submarines scuttled outside Port Phillip Heads. While it makes for an exhilarating dive, it should only be attempted by experienced and properly trained divers. The vessel sits upright on a sandy bottom in 38m, with a slight list to port. Its hull is covered by a variety of marine growth, including sea tulips, soft corals and zoanthids. Its stern faces seaward, and the stabilising fins and propeller shaft are clearly visible.
Near the bow, a depression in the sea floor, makes it possible for the diver to swim under the hull and emerge on the other side. The torpedo tubes are also visible at the bow.

Hazards and Precautions
The 38m depth calls for experience and training, correct equipment and very careful planning. Begin your ascent with plenty of air remaining for the inevitable decompression stops. Even at this depth surge can be a problem, especially when penetrating inside the wreck. If surge is present remain on the outside.
Penetration into the wreck is possible, but extreme care must be taken. A cave diving reel is essential if penetration is attempted. Once inside the wreck, it can become very dark, so good torches are essential. Care must be taken to avoid stirring up silt on the bottom, thus further reducing visibility.
