I seem to recall discussing this with you before. Not being an Australian or seeing the on the ground reality I can't really comment. I think I recall saying ads may be spillover from American influence - where the demographic reality on the ground does reflect what is seen in ads.

At the same time I see no reason to jump from there to the conclusion that we see the same trend in ads in every white country. In Hungary? Russia? Ukraine? Even Spain? Serious doubts there. Or a serious case of not enough info. People make a lot of unfounded conclusions - extrapolated from their own experiences.
