The stamp features the HMAS Wyatt Earp(formerly known as FV Fanefjord, Wyatt Earp, and HMAS Wongala).It was a motor vessel commissioned into the Royal Australian Navy (RAN) from 1939 to 1945 and again from 1947 to 1948.
Built originally as a fishing boat named FANEFJORD. Used for fishing and sealing. Purchased by Sir Hubert Wilkins for Lincoln Ellsworth who renamed her WYATT EARP. Used by him for Antarctic exploration. Sold to the Australian government and renamed WONGALA. A later change of ownership had her called Natone, and under this name she plied the east Australian coast until wrecked in a storm near Double Island Point, Queensland, on the night of 23-24 January 1959.
