I can tell you there are nearly 5 million people in regional NSW and QLD plus ACT. In SA and WA regional there are 920,000 people.
It is obviously an advantage to AFL for these areas to be ignored in the ratings, wouldn't you agree.
Using those figures that would mean about half the people in NSW and QLD are in regional areas which i personally find hard to believe. Regional to me is atleast 150km away from Sydney.
