Would a Canberra side get higher or similar attendance to the Raiders?
It's hard to say for sure, but I think AFL crowds would top the Raiders' if we got our own team.
GWS has had higher average crowds a few times, but usually sit just under the Raiders' crowds. That's with about a third of our games usually capped by selling out.
The Giants are gaining support, but they're still not really seen as Canberra's team. As a result there's very little media surrounding GWS games compared to Raiders games, and less fanatical support than a home-team would generate. There also seems to be less GWS advertising than Raiders advertising.
So with an upgraded stadium and the excitement around our own home-team, I think it's not unfeasible for the AFL team to get 50% bigger crowds than the Raiders.
