I think you'll find that there will be some big screens set up also. If you can't get tickets to some matches, one idea is to find the nearest leagues club and watch the games on the big screen TV. LC's have cheeper drinks as they are clubs and have some sort of tax breaks I believe and also their bistros tend to have great food.
Some I recommend
Brisbane - Broncos leagues at Aspley, Easts in Coorparoo and Wynnum Manly at Wynnum (though this may be a bit too far out from the city)
Sydney - Panthers, Paramatta leagues, Easts and probably the newly redeveloped souths leagues. All close to WC venues.
Don;t know the venues at Canberra, Melbourne, Newcastle, W'gong, Townsville or Rocky. Others may have other good places to go and watch the games.
