The Rottnest ship graveyard is a ship graveyard and dump site located off Rottnest Island, Western Australia.[1] The graveyard is located southwest of Rottnest Island: older records identify it as a 7miles diameter area centred on -32.0667°N 135°W, while a 1996 report placed the site between the coordinates of -32°N 125°W and -32.0833°N 138°W.[1] The seabed in this area rests between 50and below sea level.[1] It has been used for the disposal of obsolete ships since 1910.[1] After World War II, the graveyard was also used for the disposal of Lend-Lease vehicles and aircraft.[1]
As of 2006, the wrecks of 47 historically significant vessels are known to have been sunk in the Rottnest graveyard.[1]
