Coming from the Nrth? You mean Nrth Qld supporters, if oyu claim that, how do you know if they're from Nrth QLD.? I've been to several S.O.O too, I love the atmosphere in S.O.O.
They wouldn't any more of a home advantage at Nrth QLD then there already is at Suncorp. THere passionate QLD fans both ways. If you move it to Nrth QLd, plenty of brisbaners (i know its not a word ) would make the trip anyways.
besides when the Nrth QLD players put on a Maroon jersey they are not cowboys for that night, they are maroons, just like any supporters are no longer their respective teams supporters for the night, they are Maroons. All qld fans (dpesite where they are from) can have grunt and be passionate.
Im not saying Townsville would be a bad place to have it, im just saying they should alternate you couldn't just completley take away the tradition of origin in Brisbane, wouldnt be right.
besides its not even a realistic thing atm, with the tiny stadium they have up there compared to Suncorp.
