SS Nemesis was carrying coal to Melbourne, Australia, in July 1904, when she was caught in a severe storm off the coast of New South Wales. Bodies of crew members and debris from the ship's wreckage washed ashore at Cronulla, about 29 kilometers south of Sydney.

This mystery created a media storm and aroused great public interest, but the remains of the ship, which was 75 meters long, were never found and its final "burial" place remains a mystery. Subsea Professional Marine Services, a remote sensing company called CSIRO, accidentally came across the missing shipwreck.
