Post election 2010 I doubt if Wilkie would have supported Abbott whether Gillard agreed to poker machine reform or not. However, a promise was made during negotiations and I think even with the unrealistic time limits, to the best of her ability, she tried to keep it.
I always thought that pre-commitment was a bit silly, but that was intoduced into the mix to placate the clubs and pubs so that they could hang on to their high rollers. $1 limits is the way to go. I have stupidly played the poker machines for over 40 years and never have I come close to betting anywhere near $1 a spin.
The voting and gambling public still need to be convinced that the reforms may only effect less than 10% of them. When you're up against the "Limited News" press and the clubs (using money collected from poker machine takings) lying to people about licences to gamble and the local sports teams closing down, its hard to get the facts out there.
