Yep just put a stadium there and success is assured.
It’s just that easy.
That's not the only thing that would be needed mate, but that is the first and almost most important step in a long road to long term acceptance and success by the locals. If it's not in the best location and of the highest quality, being indoors is a freaking miracle and a blessing, to start with then doesn't matter how good the team perform, people will take a decent interest because they are winning, but then drop right off because the ground is average, not in a brilliant buzz location and well ho hum out of sight out of mind.
A City location means office workers, tourists and locals will trot along just for the atmosphere and entertainment no matter how the team is going. Way different then some average suburban nothing ground. You just can't get that type of response and engagement from those sorts of grounds. We have them all over this country, how much evidence do you need? We don't have any actual City stadium at all. The closest to that but it isn't is Parra Stadium and still it is going gang busters.
But this for convenience. comfort and atmosphere will be at another level. Nothing like it in Australia for footy codes. People would love it if it were to ever happen, but of course it won't.
