While the commission acknowledged the mine would exacerbate climate change impacts, it concluded that these environmental costs were outweighed by the economic stability provided to the Hunter region. The project, which generates over $1 billion annually, secured the backing of Premier Chris Minns and the NSW Coalition. Supporters emphasize that the extension facilitates an orderly transition for the 1,500 workers employed at the site, rather than an abrupt industry closure.

Critics, however, label the approval a systemic failure. Georgina Woods of the Lock the Gate Alliance warned that the greenhouse gas pollution from this single project threatens to negate state-wide carbon reduction efforts. Projections indicate the mine will generate 809 million tonnes of emissions over its extended lifespan. The controversy is heightened by Australia’s upcoming role as co-host of the COP31 climate summit, with activists accusing the government of hypocrisy for expanding fossil fuel extraction while professing adherence to Paris Agreement targets.

The project now awaits federal environmental approval, expected by year-end. If cleared, operators will be required to implement emission management plans, including purchasing carbon offsets and restricting exports to nations with policies aligned with international climate goals. Finance Minister Courtney Houssos maintained that the state remains committed to net-zero targets while acknowledging the persistent role coal plays in the regional economy.
