Plus it is a growing sport here. It's only a matter of time before more are playing in the league. But yeah a nz team is a long way off. It is something the AFL is considering in the long term though, I've heard a lot of rumours that they're eyeing up Wellington. Would be interesting if it ever did happen.
I don't think I'd be a season member, but is certainly go along to the odd game and follow results. When I was watching it the other night, I was enjoying it, but also thinking itd be a lot more exciting if you actually supported a team (I chose a team, but in the end didnt actually care who won). So a Wellington team would make for some exciting games.
