The Liberals are set to dump net zero after a strong majority at a special party meeting spoke against the existing commitment to it.
In a show of strength ahead of the debate, a phalanx of more than a dozen from the party’s conservative faction walked together down the corridor to the meeting.
At the front of the group were three women: Sarah Henderson, who was publicly critical of Opposition Leader Sussan Ley last week, Jacinta Nampijinpa Price, whom Ley forced off the frontbench, and new New South Wales Senator Jessica Collins.
