Cementco started life as the Australian Army amphibious operations support ship Crusader (AV 2767) in 1945 and carried equipment between New Guinea and Australia. In 1947 she was sold to the Queensland Cement and Lime Company. Renamed Cementco, she carried dredged coral from Moreton Bay to the company’s cement factory at Darra. After retirement in 1984 a buyer could not be found, so the hulk was sunk as a dive wreck at Flinders Reef off Cape Moreton in 1986.
