A significant internal divide has emerged within the Australian Greens party regarding a new policy for a koala national park in New South Wales. The federal government, led by Labor, has reached a deal that would permit industrial entities to use the park as a site to offset their climate pollution. While the Greens party leadership has decided not to join the Coalition in blocking the regulation, the decision has faced internal pushback.

Three senators—Nick McKim and Vanessa Bleyer from Tasmania, and Jordon Steele-John from Western Australia—have publicly declared their intention to cross the floor. By doing so, they will vote against the party's official stance when the regulation comes to a vote this Thursday. The move highlights a broader tension between the party and environmental advocates, who remain deeply split over whether the government’s regulation is an acceptable compromise or a dangerous precedent for environmental policy. While the party leadership appears to have prioritized the deal with Labor, these three senators have signaled that the inclusion of industrial offsets within a protected national park is a line they are unwilling to cross.
