50th anniversary of former PM Harold Holt's disappearance

A low key memorial is scheduled to be held this weekend to mark the 50th anniversary of the disappearance of Harold Holt, Australia's 17th Prime Minister. He went missing while swimming off Cheviot Beach in Melbourne in 1967 and was never seen again. On the anniversary (17th Dec) of his disappearance, his political successors agree there's more to his legacy than his mysterious disappearance.
