SS Wandilla was a steamship built in 1912 for the Adelaide Steamship Company. The ship operated on the Fremantle to Sydney run until 1915, when she was acquired for military service and redesignated HMAT Wandilla. Initially used as a troop transport, the vessel was converted to a hospital ship in 1916. Wandilla was returned to her owners at the end of the war, then was sold to the Bermuda & West Indies SS Company and renamed Fort St. George in 1921.
