You're comparing an away trip to Catalans to the WCC? Really?
Makes no sense, we are in the middle of a crippling recession, how many Hull or other SL teams fans would follow there side to Dubai, Aus, NZ? Not many that is a fact. If you just look at away attendances at Catalans it's a hand full at best and thats only the south of France.
There's no benchmark for a game in Dubai to compare, so I aren't going to put a number on it. I aren't going to be a pessimist and do down the sport so I can somehow gloat if it does fail.
So NO neutrals would be bothered to save £2000 + for a trip to Australia to watch a team they don't support.
What would your guess be at the attendance then if it was held in Dubai if it's more than 2,000?
If the game was held in Aus and announced early, people could save up and go. Whether they be from Aus, England or wherever, they could save up.
