AFL Grand Final or Melbourne Cup??

One of them is Melbourne's biggest day.   Football or horse racing?   Despite my best efforts, I can't think of anything local that rivals these events in excitement, numbers and fervour.   I don't particularly follow a footy team and I  rarely have a bet on the races, so I have no vested interest in either.   So, why can't I think of other events that can match these two?
Anyone have a suggestion??   Aussies, that is.  We have to compare oranges with oranges.
