SS "Dorrigo was a cargo and passenger steam ship. It was built under the name of Saint Francois" by the Smiths Dock Company at the South Bank in Middlesbrough on the River Tees in Northeast England for the Compagnie Navale de l'Océanie for the Pacific Island postal and general trade service, for which it sailed the waters of the Pacific from 1914 to 1921. The ship suffered minor damage during the First World War during the Bombardment of Papeete, prior to coming into the hands of the Langley Bros who placed it in the Sydney to Coffs Harbour route from 1922 to 1925. Upon the demise of the Langley Bros shipping firm in 1925 the vessel came into the service of John Burke and Co and was used for the Northern Queensland runs prior to its loss on 4 April 1926.
