Having just 2 clubs in Perth may suit the vested positions of the supporters & officials of those two, but whats best for the game? What about the best interests for WA kids getting a chance in the AFL draft? What about maximising attendances & commercial interests. Even maximising the use of the new stadium they have.It's not as simple as that. Some of that population growth is going to places that don't have a team right now (and won't for the foreseeable future) meaning the increase in those areas is irrelevant in terms of representation. Also, a population increase in Melbourne is more valuable to the game than an increase in Sydney, because the culture is much more geared towards AF, meaning it's much easier for migrants to be sucked into the AF orbit.
When you scale for these two things, perhaps Melbourne isn't overrepresented much, or not at all. Would you seriously argue Brisbane is underrepresented in terms of the appetite of the market for AF? Brisbane has 1/8 of total population growth in Australia, but there's no way in hell we have 1/8 of the nation's interest in AF. Melbourne is probably overrepresented in a direct comparison to Perth, but I've heard over and over from Perthlings that there's no appetite for a third team, so it's pretty irrelevant how represented they are.
