helllo, glad to see an Aussie fellow here, unfortunately i dont have a sim to help you out on that. But i can tell you my experience on the machine. As it is a 3 player machine, I once played with an aussie guy and a chinese lady, because i'm not alone at the machine so i thought i'd wong in/out at TC +1.
I bet for one round and then wong'ed on the other, the aussie dude was annoyed and told me if i want to bet, then keep betting, if not, leave the machine. The chinese lady was also annoyed about it, said to herself it's hard to win with someone siting in for a round and out for the other... My advice, find a quiet club and play alone or don't wong...
