G'day MrWhite - off the top of my head there are two places we know of which are fairly conveniently located on the river - so if you don't like one you can walk across to the other. Fellow forumer's will no doubt have other suggestions.
Brewwerkz has a number of TV's and is popular for such events. The Riverside Point branch is the one I'm thinking of:

The other is next to the reverse bungy on the other side of the river in Clarke Quay. We can't remember the exact name of it, sorry - perhaps someone else here can "top up" this posting for you.
Enjoy your trip! P&C
