NSW Greens MP Sue Higginson has issued a public appeal to her federal counterparts, requesting they refrain from joining the Coalition and One Nation in blocking a state-level environmental initiative. The dispute centers on a federal regulation—a carbon credit method—that would allow the New South Wales government to receive millions of dollars in credits in exchange for establishing a national park dedicated to koala conservation.

The issue has sparked internal friction within the Greens and among environmental advocacy groups. Higginson, a former lawyer and forest campaigner, is the first member of the party to speak extensively on the matter. The core of the disagreement involves the mechanics of the carbon credit system and whether the state’s plan for the park qualifies under federal guidelines. While proponents argue the funding is essential for conservation efforts, opponents suggest the regulatory framework may be flawed or misused. The situation remains a point of contention as the federal vote approaches, with Higginson attempting to consolidate party support to ensure the deal proceeds despite the opposition's efforts to halt it.
