How many Kegs will they go through on the first event likely Australia vs England One Dayer?

60,000 people

10,000 average 6 beers
15,000 average 3 beers
10,000 average 2 beers
10,000 minors 0 beers
15,000 don't have a beer

Say 500ml per glass including wastage.

That's just under 1000 kegs.

* These figures and assumptions are totally made up in my head.

Another assumption is around 300 kegs per AFL game.

And 1/2 a keg for the Ed Sherman concert.
