I'm heading to Cairns for the game, taking Mrs Muscles (skunks tragic) along for the break. I called the club last week and Jess said that it was unlikely that there would be any tickets left over, because there had been a big response from members.
So I logged onto TicketDirect, who have the tickets for the game, and tried to buy two seats together in the stands - figuring it would be better to sit next to she-who-must-be-obeyed - than to leave her and the credit card at large in a tourist spot. It was impossible to buy two tickets together at the ground. There was plenty of standing room available though.
Point being, if you are planning on going to the game in Cairns, it would be good to tell the club early.
