NSW moves to allow Mount Pleasant mine output

Highlights

NSW Labor government will introduce legislation enabling MACH Energy's Mount Pleasant mine to increase annual coal output from 12.5 million to 16.5 million tonnes through 2032, securing 400 jobs.
Legislation provides partial, not full, approval for the mine, as the original 22-year extension granted in 2022 was invalidated following a High Court decision requiring Scope 3 emissions assessment.
The proposed bill mandates coal be sold only to Paris Agreement signatories and sets Scope 3 emissions limits, prompting criticism over precedent and demands for detail from environmental and political groups.

Planned legislation and operating terms

As reported by ABC News, the NSW Labor government says it will table legislation in the coming weeks to preserve 400 jobs at MACH Energy's Mount Pleasant mine in the Upper Hunter. If passed, the measure will allow the mine to lift annual coal production from 12.5 million tonnes to 16.5 million tonnes until 2032, while the company enters a jobs guarantee covering 400 direct roles over that period.

Premier Chris Minns says the proposal is designed to match the site's current workforce profile and existing extraction activity. He argues the intervention is needed because, without it, those jobs are at risk before Christmas.

Minns also says the legislation is not a full approval for the mine. Instead, he describes it as a partial approval while MACH continues its broader application process through the Land and Environment Court after the original approval granted in 2022 was invalidated.

Legal and policy fallout for the coal sector

The move comes after the High Court found the NSW Independent Planning Commission failed to consider downstream, or Scope 3, emissions when assessing MACH's proposed 22-year mine extension. That ruling effectively halted the extension and raised the bar for planning authorities assessing fossil fuel projects with overseas emissions impacts.

Minns says the proposed legislation will require MACH Energy to comply with Scope 3 limiting rules and to sell coal only to countries that are signatories to the Paris Agreement. Environmental critics are pressing for more detail on how those conditions would work in practice.

DAMSHEG president Wendy Wales says in a statement that the group does not want Hunter workers to lose their livelihoods, but argues a law drafted for one company days after an adverse High Court ruling is an inappropriate use of the legislative process. Greens climate change spokesperson Sue Higginson also says the bill would amount to significant overreach and set a dangerous precedent by creating special laws for a specific project.

Minns rejects the idea that the case creates a broader template for future interventions, saying Mount Pleasant is in a unique position. He maintains that allowing operations to continue is the only practical way to protect jobs while the mine's longer-term legal pathway remains unresolved.

In our earlier article on India’s clean energy investment surge, we noted that capital inflows into renewables and transition infrastructure rose 15% to $72 billion, lifting India to fifth place globally and ahead of France. We also highlighted that this momentum supports long-term buildout across power, industrial fuels, and transport, reinforcing how policy and financing trends are reshaping energy markets alongside legacy fossil-fuel activity.
