Nice quiz! Would it make more sense to drop the 'as' in the Tullamarine question? And as for the AFL team, there are technically 9 teams from Melbourne (including it's suburbs) but only one goes by the name Melbourne, so the question is fine.
Also, a random fact is that Melbourne used to be called Batmania.
Melbourne was only called Batmania by one correspondent - possibly tongue in cheek - in 1835. You can see this in a letter and a weird news item in Trove.
