SS Xantho

SS Xantho was a steam ship used in the colony of Western Australia as a pearling transport and mothership, as a tramp steamer, carrying passengers, including Aboriginal convicts and trade goods before she sank at Port Gregory, Western Australia in 1872. She was powered by a horizontal trunk engine, and was the first steamship to operate in north-western Australia.

The wreck was forgotten until 1979 when it was found. Subsequent investigations by the Department of Maritime Archaeology at the Western Australian Museum, in concert with the Museum's Department of Conservation and Restoration saw the trunk engine recovered in 1985. In the ensuing years it was gradually restored for display at the museum.
