A difficult one to compare because a large percentage of the Australian population are considered obese by the World Health Organisation so the "average Australian" weight doesn't stack up in this discussion so to speak.
What about airline flight crew weights, the military, police, pilot medicals, one could say the same about them too, it's just a matter of degree?
It's a little like saying that I'm annoyed because I can't be the pinup girl for David Jones because I'm not good looking enough so I am being discriminated against.
