i think in most places where both genders play in choosing their mates you find long term relationships are more based on personality than appearances.
Attractive people are more likely to have opportunities in life, thereby finding success easier. Unattractive people have to resort to any means necessary to survive, including breaking the law.
My theory is that since Australia was founded by criminals the majority were unattractive, add into it the fact they were British (bad teeth, big ears, pale skin) and multiply by 150 years of shallow gene pool (Aus isolated) and you've got a recipe for unattractive.
Plus majority of the crimes these convicts were convicted of were relatively harmless as most just stole a piece of bread or livestock in order to survive. Very rarely was it for things like murder or abuse. So a lot of them weren't really criminals and actually good people as they were just trying to survive and feed their families
I think most of the people who committed murder or things of the like we're usually sentenced to death
So they wouldn't have a chance to get to Australia
