Tasmania is 100% AFL., so it is a good market for AFL to invest in.
It's well known the ACT has a high transient population, so people come to Canberra with set alliances to teams and sports. The ACT is also smaller and more diverse when it comes to sports. So being super, super generous, its a 70/30 split with Rugby (all forms) being the main sports. Looking at the ACT right now, they are trying to keep a Women’s soccer team alive, the fantasy of a A League team continues which suggest that funding is a real issue. The ACT has one of the highest sports participation rates and a diverse range of sports which makes it a competative market for local sponsorships which are very limited. So it’s not just simply an Rugby v AFL market arguement.
So, at best, the 480K ACT peoples you are using to base your AFL argument on is in reality is more like less than 200K on a really good day.
Probably one of the best indicators where sports, sports sponsorship and the ACT are heading is the Vikings Group. Beyond their rugby they also have many other sporting teams. They appear to be powerhouse with their own grounds etc. But they are desperately trying to move operations out of the ACT as they are struggling financially, and the ACT government is slowly cutting off their revenue streams (yes, the pokies!). That means less funding for community sports which the ACT Government will need to pick up. The ACT doesn’t have the revenue like the Tasmanian market and its already a crowded market. Ask the Raiders and Brumbies.
The only reason the GWS are in Canberra is the approximately $700k+ they get paid, per game, from the ACT Government as part of the 10year $28.5mil deal.
