Betfair has them neck and neck with $2 for the coalition and $1.92 for Labour - swinging around in that $1.9 - $2 range for the both of them
IMO Tony will get 73 and the support of the 3 ex national independants.
Part of the game is for the independents to throw the option out there that they will go with labour to get a better deal out of it all. Their traditional liberal / national elecorates would never forgive them if they sided with labour, they know this . They'll get a good deal, you watch.
Just put $50 on Tony @ $2.00 to fund my mid week beer requirements this week
