The counterpoint to that argument is that AFL isn't the number 1, 2, or 3, rated football code up here in terms of talent. The vast majority of the tented kids are still funnelled in to Rugby League and Soccer in the public school system and Rugby Union and Soccer in the private school system.Both Qld and NSW have more people playing AFL than SA does.
I've been out of school for nigh on 30 years, but I'd be genuinely surprised if there's more than a token school based AFL comp anywhere in QLD. Probably more chance of a girls comp developing.
Up here, many kids play the sports their parents follow or push them towards. You look at the majority of kids to successfully make it through the Gold Coast and Brisbane academies and make it to the AFL, they come from Victorian families who support an AFL team, who moved up to QLD for job opportunities when the kids were young.
Brisbane:
Jacob Allison (Vic)
Eric Hipwood (Vic)
Ben Keays (Vic)
Harris Andrews (Vic)
Gold Coast:
Brad Scheer (WA)
Jack Bowed (Vic)
QLD and NSW might have more people playing AFL (which I genuinely query as I reckon most sports fudge the numbers when they talk about how many kids/adults play the sport) than SA, but that will purely be a result of our significantly larger populations, not because AFL is the number 1 football code in the state.
What will be interesting, will be to watch female participation rates with the NRL introducing a womens comp next year.
