Whitehaven Coal’s planned $1 billion Winchester South coal mine in Queensland has been put under new examination, with environmentalists mounting pressure to add the latest climate modelling to a pivotal Land Court fight.
The mine, which has the potential to generate over 500 jobs for miners and an estimated $696 million in royalties, is also estimated to produce a maximum of 600 million tonnes of carbon emissions during its 30-year operation. The extent of such emissions has now become a key point of debate in the court proceedings.
Central to the controversy is whether or not the court is to accept a new expert report on climate written by the Australian Conservation Foundation (ACF) and lodged recently, weeks before the final submissions are due. Whitehaven has opposed the acceptance fervently, claiming the late submission might cause undue delay to the case.
Courtroom Clash Over Climate Science
At a recent hearing, Whitehaven Coal tried to stop presentation of evidence by top climate science scholar Dr Setu Pelz, whose report supposedly estimates the mine’s impact in terms of fresh modelling. Lawyers, acting on behalf of the ACF and Mackay Conservation Group, contend that the expert evidence is critical to an appreciation of the climate impacts of the mine set against Australia’s net-zero commitments and changing science.
Justice Fleur Kingham, sitting in the Queensland Land Court, has granted conditions, but cautioned against duplication and delay risks. The court has fixed 31 July 2025 as the ultimate deadline for all to provide their expert evidence.
Whitehaven’s representative called the proceedings “an action to ’cause chaos'” and claimed there was already sufficient climate evidence in those cases in earlier proceedings.
Economic Payoffs vs Environmental Dangers
The Winchester South open-cut coal mine, located west of Moranbah, is to extract metallurgical coal for customers in the steel-making business. Whitehaven said the project is to create jobs in their local area, stimulate investment into the region and generate long-term growth.
But the scale of the project’s emissions has given environmental groups cause for concern. The emissions from the mine are projected at 600MT CO₂ equivalent which has the potential of being one the largest, industrial contributors to carbon pollution in Queensland.
“Climate pollution from this mine would blow Australia’s carbon budget and contradict Australia’s climate commitments. The public has a right to know how much it is contributing.” ACF campaigner Kelly Albion said.
Regional Voices and Community Impact
While the project does have some support in Moranbah and surrounding suburbs, there remains a divided opinion to the project. For others, jobs and royalties are seen as a positive, particularly in a period of lessening regional economies. Local business associations and trade unions argue that Winchester South can revive the area’s mining historic traditions and their royalties can assist the state in funding major infrastructure projects.
Others within the community express concern about health effects, environmental damage, and long-term implications of increased coal production.
One resident, requesting anonymity, stated, “We have seen what coal can do—both positive and negative. If the project is allowed to happen, it has to be with total transparency and accountability.”
The Legal Stakes
The result of this case would establish a precedent for environmental risk and climate science assessment in approvals for mining. Legal experts think that the decision of the Land Court will have an impact on how upcoming projects all over Australia should measure and reduce emissions.
This is not the first legal opposition Whitehaven has encountered. But the addition of fresh scientific data so near to trial adds extra complexity. Opponents of the project contend that rapidly changing climate data needs to guide approvals, especially for projects with lifespans of decades.
Whitehaven, meanwhile, insists it has adhered to all the regulatory processes, undertaken comprehensive environmental studies, and participated in public consultation pursuant to Queensland planning laws.
Government and Industry Keep a Close Eye
The Queensland Government, which will make the final determination on granting mining leases and environmental approvals, is watching closely. A court suggestion is not compulsory but has great influence.
Industry organizations like the Queensland Resources Council and Minerals Council of Australia have expressed fears that legal activism could hold back critical resource development, with threats to Australia’s economic competitiveness and energy security.
What’s Next?
July 31, 2025: Last deadline for expert witness.
Court hearings will resume shortly thereafter.
A decision later this year is expected.
If the court rules in the favor of the conservation groups, it could suggest the mine be denied or put under tighter conditions. If there is approval of the project, it could move on to licensing and development phases within months.

Conclusion
Whitehaven Coal’s legal struggle regarding the Winchester South project is more than a courtroom battle—its a turning point in the balance between economic development and environmental responsibility in Australia. As scientific knowledge, legal tactic, and public opinion intersect in Queensland’s Land Court, the mining sector observes closely.
Whether the court values procedural speed or assigns significance to new climate modelling will probably determine the course of resource approvals across the country. For the moment, both camps prepare their make-or-break arguments before July 31—and the stakes could not be higher.
