I work at Mt Pleasant & live locally on property! We have been in the area since 2017. Getting the extension will give me job security , financial stability to stay continue to live locally & Mt pleasant can continue to make positive community contributions. We love that we live close to work & can easily have the perfect work, life, family & farming lifestyle!!

As a Thiess employee I support the project extension.
Thiess currently has over 700 employees at MPO, most of whom are Hunter Valley residents and my colleagues.
Mount Pleasant will deliver over local 1,000 jobs and provide long term certainty for thousands of local families.
The livelihood of multiple contractors, suppliers, and local businesses rely on supplying operations such as Mount Pleasant.
Thiess has been involved with MPO since 2017 and was an integral part of the operation getting off the ground . Thiess has and continues to provide significant financial and in-kind support to local community organisations.

• I am a Director of MACH Energy and I am writing to support Modification 8 (MOD 8) to extend the approved mining period for the Mount Pleasant Operations under DA 92/97.

• Mount Pleasant plays a significant role in the Muswellbrook community and across the Hunter Valley. Beyond direct employment at the mine, the operation supports a wide network of local contractors, service providers and suppliers whose businesses depend on ongoing activity in the region.

• A large proportion of the Mount Pleasant workforce lives locally, and the operation supports hundreds of families who rely on stable employment in the region. For many workers, Mount Pleasant provides the opportunity to build long-term careers while continuing to live in the Hunter Valley and support their local communities.

• The Hunter Valley is entering a period of transition as several long-standing mining operations in the region approach closure. These developments are already creating uncertainty for workers, contractors and local businesses that depend on the mining industry. In that context, the potential closure of Mount Pleasant in December 2026, if MOD 8 is not approved while the SSD 10418 appeal continues would add further pressure to the regional economy and the local community.

• Mount Pleasant has also made an important contribution to the State of New South Wales through royalty payments, with over $650 million paid to the State since operations commenced. The operation also continues to play a role in supporting NSW’s domestic coal supply, which contributes to the reliable generation of electricity for households across the State.

• For these reasons, I believe Modification 8 is an important step to provide stability for workers, businesses and the wider Hunter Valley community. I support the approval of MOD 8 so that Mount Pleasant can continue to operate and contribute to the region and the State.

I support the Mod 8 Extension of Mine Life - as it provides an important role in the Nations economy and also provides a large amount of jobs in the NSW region

I strongly object to the project expansion modification. It should not be classified as a modification at all as it is not “substantially the same development” as the one previously approved (DA 92/97). Calling it a “modification” is merely a means to avoid independent review, and is disingenuous. This project must go to the Independent Planning Commission (IPC) for proper assessment.

The project is massive, damaging, and unnecessary. This huge mine expansion will create 1.5 million tonnes of local greenhouse gas pollution in the next ten years in NSW and over a 100 million tonnes in downstream emissions at a time when our state is not on track to meet its legislated 2030 or 2035 emissions reductions targets. The people of NSW are already suffering the impacts of climate change, including in the Hunter region and adding further greenhouse pollution will do unacceptable harm to the public interest. Further, the NSW Court of Appeal’s Denman Decision made it clear that the local impacts of climate change caused by the downstream greenhouse pollution from NSW coal have to be considered by planning authorities. As this decision is now in the High Court, acceptance of this application will cause legal and practical confusion with environmental and social consequences for the area.

Finally, approval would inflict harm on our people and our economy. The people of NSW are already dealing with increasing bills and escalating dangers from climate change fuelled extreme weather. Our local communities in the Hunter do not need a mine expansion: they need to meaningful support to transition away from an industry that doesn't harm their health or damage the planet we all share. The expansion of this mine is in direct contradiction to the Government's own advice from the NSW Net Zero Commission in December of last year that “[c]ontinued extensions or expansions to coal mining in NSW are not consistent” with NSW climate law nor with the Paris Agreement temperature goals. Do not let this pass without scrutiny of the IPC.

As a residence and fellow coal mine worked I fully support the continuation of mining in the Hunter Valley. Mining operations are completed in a responsible and sustainable manner and over my 25yrs i have seen good adhesion to compliance by most operators

I support the proposed Modification 8 – Extension of Mine Life.

As a surveyor with Fyfe Pty Ltd, I have been involved with the site since the early stages of the project and have seen firsthand the professionalism with which the operation is managed. The mine has consistently operated to a high standard with strong compliance, safety, and environmental management practices.

The proposed extension will allow the continued operation of an established site while maintaining employment opportunities for many local workers and contractors, including those who support the project through technical services such as surveying and engineering.

Based on my experience working on the project over time, I believe the mine is well managed and capable of continuing to operate responsibly under the proposed modification.

• I am a Director of MACH Energy and I write to support Modification 8 (MOD 8) to extend the approved mining period for the Mount Pleasant Operations under DA 92/97.

• Mount Pleasant has become an important part of the Muswellbrook community and the broader Hunter Valley. The operation supports local employment while also creating opportunities for contractors, suppliers and service providers who contribute to the broader regional economy.

• The operation has also played a meaningful role in supporting local communities. Through MACH’s Community Sponsorship Fund, more than $2 million has been provided to local schools, sporting clubs and community organizations. These programs help strengthen community connections and support activities that are important to local residents.


• Mount Pleasant plays an important role in supporting the Muswellbrook community and the wider Hunter Valley region. The operation maintains a strong local workforce, with more than 70% of employees living in the Hunter Valley and is expected to support over 1,000 jobs across the region. In addition to direct employment, the operation creates opportunities for contractors, suppliers and service providers whose businesses depend on continued activity in the regional economy.


• The Mount Pleasant Operations also contribute significantly to the State of New South Wales through royalty payments, with over $650 million contributed to the State since operations commenced. The mine also forms part of NSW’s domestic coal supply beyond 2026, supporting electricity generation that helps ensure reliable power for households across the State.

• For these reasons, maintaining the continuity of Mount Pleasant is important not only for employment but also for sustaining the broader economic and community contributions associated with the operation. Modification 8 provides a practical pathway to allow these benefits to continue. I support the approval of Modification 8 to extend the approved mining period for the Mount Pleasant Operations.

I am writing to express my support for the continued operation of the Mt Pleasant mine. I currently work on site as a Maintenance Planner, and this role is not only my livelihood but also the foundation of my long‑term career in the mining industry.
Working at Mt Pleasant has allowed me to develop valuable technical and planning skills, contribute to safe and reliable operations, and maintain financial stability for myself and my family. The opportunities I have here simply do not exist in many regional areas, and losing this job would have a major impact on both my personal circumstances and my future career pathway.
Mt Pleasant plays a crucial role in sustaining local employment and supporting the broader Hunter community. The mine provides stable jobs, apprenticeships, contractor opportunities, and local business activity—benefits that extend well beyond the site boundary. As someone who works here every day, I see firsthand how committed the workforce is to safety, efficient operations, and continuous improvement.
From a planning perspective, Mt Pleasant has built strong systems that ensure equipment reliability, responsible operation, and long‑term viability. The team takes pride in doing things the right way, and I am proud to be part of it.
For me, Mt Pleasant is not just a workplace—it is where I have built my career, my stability, and my sense of purpose. The continuation of the operation directly supports my ability to live and work in this region.
I respectfully ask that this submission be considered as a genuine reflection of how important Mt Pleasant is to the people who rely on it every day.
Thank you for taking the time to review my comments.
