因为绿党和工党拨票的,工党和绿党等于半结盟。上届选举也是这样的。这届选举7月19日工党绿党宣布在大选中也将互拨选票
Labor is pandering to the Greens with countless, very dubious 'environment initiatives' for the express purpose of securing Green preferences at the looming Federal poll, and the state election in 2012. Labor-Green arrangement was demonstrated, with the announcement that each will preference the other for the 21 August poll. Their joint claim that this will occur in "selected seats" - and the Senate - is itself duplicitous.
In fact, Labor will preference the Greens (and vice-versa) unilaterally, in all seats - and in all Senate situations.
