The Dunraven was a British steamer merchant ship on route from Bombay to Newcastle, England with a cargo of timber and cotton when she struck the reef at Beacon Rock on the 22 April 1876. The ship was holed in three places, fire broke out and she overturned and sank. A conflicting version of events suggests that she lay impaled on the reef for several days before fire engulfed her and she sank.


She lies upside down with her stern at 29 metres and bow section at 18 metres. The best of this dive is by penetrating the hull from either the stern, the broken midship or bow. The interior of the ship is home to innumerable fish and corals including groupers, lionfish, scorpionfish and swarms of glassfish.
