Coode Island, was an island at the convergence of the Yarra and Maribyrnong Rivers, 4 km west of central Melbourne, Australia. Today the low-lying land is part of the Port of Melbourne, site of Swanson and Appleton Docks and their associated container storage and rail yards, as well as a number of chemical storage facilities.
Originally extensive low-lying wetlands, the area became an island after a channel was dug to shorten the length of the Yarra River in 1886. A shipping canal was constructed to the south of the existing course of the river through Fishermans Bend, to allow access from the Port of Melbourne to Yarraville. The boundaries were the canal on the south, the Maribyrnong River on the west and the Yarra River on the north and east. Once formed, the island became an industrial area of 97 hectares. The island was named after Sir John Coode, an English harbour engineer who was engaged by the Melbourne Harbour Trust to select the optimum route for the canal as part of the Port of Melbourne. The former course of the Yarra River was slowly filled in over the years, along with the associated swamps, and by the mid-20th century, Coode Island was no longer a true island, although the name remained.
By 1909 the area was being used as an animal quarantine station and after 1915 as a sanatorium for victims of bubonic plague and other contagious diseases. By the 1920s the area was inhabited by hermits living in huts and abandoned ships. In 1927 the Larkin Aircraft Supply Company had set up operations on the island, including a factory and aerodrome, which was used until World War II.
