Here in Australia our greatest disappearance for a public figure was:
Harold Edward Holt, CH (5 August 1908 – 17 December 1967) was an Australian politician who became the 17th Prime Minister of Australia in 1966. His term as Prime Minister dramatically ended in December of the following year when he disappeared while swimming at Cheviot Beach near Portsea and was presumed drowned.
Holt spent 32 years in Parliament, including many years as a senior Cabinet Minister, but was Prime Minister for only 22 months. This necessarily limited his personal and political impact, especially when compared to his immediate predecessor Robert Menzies, who was PM for a total of 18 years.
