I think it's incumbent on the non-Victorian teams to raise at least one hair-brained Grand Final scheme a year for the next 40 years if only to highlight the inherent, bald-faced Victorian self-interest on display by signing a contract that extends to second half of the 21st Century.
It might not lead to a change in the GF location, but it might force the AFL to look at other ways to mitigate the unfairness now contractually baked into the system for decades to come. Maybe that's more games at the MCG for interstate teams, maybe that's permitting chartered flights, maybe that's requiring (as part of the sponsorship agreement) the airline sponsor to put on extra flights to interstate GF team's fans at a reasonable price, maybe it's home final compensation system, maybe it's a greater ticket allocation for interstate fans. There are any number of things the AFL could do, short of moving the GF, to mitigate that part of fairness they whored off to the (presumed and non-tendered) highest bidder. .
They aren't doing any of those things because they don't consider there is a problem. They are wrong, and anything that puts pressure on them to reconsider that position is a good thing.
