NSW Government Approves Expansion of Mount Pleasant Coal Mine

Core Decision
On October 19, 2026, New South Wales Premier Chris Minns announced that the state would intervene to grant MACH Energy a legislated approval to raise the annual production ceiling at the Mount Pleasant coal mine near Muswellbrook from 12.5 million tonnes to 16.5 million tonnes through 2032. The move follows a recent High Court of Australia judgment that declared the 2022 approval by the NSW Independent Planning Commission invalid because it failed to account for the mine’s “scope 3” emissions—carbon released when Australian coal is burned overseas.
Background and Legal Context
The High Court ruling, issued a fortnight before the Premier’s announcement, highlighted that the planning process must consider the climate impact of exported coal. The decision sparked calls from the federal Coalition and One Nation for new state legislation to overturn the court’s finding. In response, the Minn s administration prepared a legislative package that would require future coal exports to be limited to countries that are parties to the Paris climate agreement.
Official Statements & Government Response
Premier Minns framed the intervention as a “partial approval” intended to protect the local workforce while the legal implications of the High Court judgment are resolved in lower courts. He emphasized that the decision was driven by the risk of about 400 jobs being lost before Christmas if the expansion were delayed. Natural Resources Minister Courtney Houssos indicated that the forthcoming legislation would embed scope 3 emission limits, effectively restricting exports to Paris-signatory nations.
Opposition and Criticism
Greens MP Sue Higginson condemned the action as a “capitulation” to a billionaire coal company, accusing Labor of bypassing the planning process and enabling unassessed climate pollution. Environmental coordinator Georgina Woods described the intervention as “cynical and dangerous political interference,” suggesting the government was manufacturing a crisis to favor the miner.
Production Limits and Employment Guarantees
In exchange for the higher output allowance, MACH Energy agreed to a legally binding jobs guarantee that obligates the company to maintain staffing levels. The government’s approach seeks to balance the stated climate objectives with the immediate economic concerns of the Hunter Valley community.
