I believe this view was based on a normal Australian male living in those times (1958). In my view this image represents a person living in those tough times and who was fashioned by his/her environment making him/her the person that he was. This explanation also vaguely matches ‘Michael’ in Crocodile Dundee. A statement that well describes Dundee and drinks deeply on occasion. Although he is the world’s best self-confidence man. I believe there possibly was a lot of truth in this explanation at the time. Russell Ward goes into describing details like even words and I don’t think he could make this entire up in his head because it wouldn’t be published if it was totally not true.
During 1958 Australia was still a very youthful country with a small population based on people from many nations. The towns were small and jobs would have concerned manual labour rather than being ‘thinking’ jobs, eg: lawyer, doctor, orthodontist, etc. I think the conditions that exist in Australia back then could have shaped the person that Ward describes here to some extent. From my position this statement still holds quite a lot of truth, even today. They are frequently in the ‘public eye’ because they are popular and people know them from films or music and the media reporting of every scam and modify that goes on in their personal life.
