We struggle to fill ANZ twice. We can do it once as its an 82,000 seat stadium. However selling 160,000 odd tickets is very hard to do, especially for 2 games in 6 weeks.
In Brisbane they fill a 55,000 seat stadium twice, but that's a lot easier (110,000) to accomplish when you are winning. Wait until they go a few years without winning and they'll find their 2nd game tickets very hard to sell.
Sydney has to sell the comparing numbers of a 3rd game at Suncorp just to make it worth their time for a 2nd game.
What pisses me off isn't that the game is in Melbourne. Its that game 3 is in Brisbane again. Whyd o they get the 3rd game again? There's something not fair about that. If it comes down to a decider again, they get the home advantage..AGAIN!!
