Ummm.........I disagree somewhat. I think risk of Socceroos fans having 'Asian fatigue'. Yes for sure a full house at say Docklands (50,000) for WC qualifier with meaning, verus any of those Asian nations.
For a friendly against an AFC side that Australia already play fairly regularly I'm not so sure. Put it this way you'd get a fair contingent of AWs fans for a game in either Melbourne or Sydney.
I went to the pre 2010 WC friendly at MCG, between Socceroos & AWs and the crowd was 60,000 plus from memory. Admittedly was a World Cup farewell for both sides who had already qualified, and NZ football was on a high from the Bahrain game.
