The unidentified body on Christmas Island was a sailor in the Royal Australian Navy (RAN) found on a life raft in the Indian Ocean, off Christmas Island, in 1942. He is widely believed to originate from the RAN cruiser , which sank off Western Australia in November 1941 after a battle with the German auxiliary cruiser . While 318 of 399 personnel survived, the 645 crew of "Sydney" was lost with all hands. The locations of the shipwrecks were unknown until March 2008.
