On 17 December 1967, Harold Holt, the Prime Minister of Australia, disappeared while swimming in the sea near Portsea, Victoria.
An enormous search operation was mounted in and around Cheviot Beach, but his body was never recovered. Holt was presumed to have died, and his memorial service five days later was attended by many world leaders.
