Despite being a Queenslander, I'll admit that the Gabba is probably considered 4th tier in terms of AFL stadiums, yet it was able to host a Grand Final that drew huge ratings and the game's quality wasn't effected at all. There's also the narrative of what a novelty grand final will bring to the state and how it could be perceived as "New". Whether you agree with it or not, every Grand Final at the MCG feels the same. The same tune is repeated year in, year out, the same commentators, the same production, etc. Can you imagine the event of a Grand Final in Perth? Or Adelaide? Or Sydney? You would get something different each year instead of tredding the predictable nature of showing the game at the G. Now, that's not to say that the MCG should host the grand final, however, why not share the event around? I know I would rather watch a grand final in Perth than at the G after seeing that it can work.
