Who was the first living Australian to appear on an Australian postage stamp?

Gwoya Tjungurrayi also known as One Pound Jimmy was an aboriginal elder and lawman of his people and died in 1965 at age of 70. He was photographed in 1935 and the image was used in September 1936 issue of a tourism magazine called "Walkabout".
