HMAS Swan
A former destroyer escort scuttled in Geographe Bay, prepared with multiple access points.
The HMAS Swan, scuttled off Dunsborough in 1997, is one of Australia's major artificial wreck dives and should be treated separately from ordinary reef diving.
The vessel was prepared for diving with multiple access points cut into it, and the superstructure rises to within a few metres of the surface while the seabed sits around 30 metres.
That depth range means the wreck accommodates both straightforward external diving and, for appropriately trained divers, interior routes.
