Our Future Plans

Continuing to mine at Metropolitan will provide jobs and coal royalties for people in New South Wales while safely mining steelmaking coal.

The Path Forward

Metropolitan Mine has lodged a modification to operate until 2031 and is preparing a State Significant Development (SSD) application to continue mining to 2044. This two-stage approach includes:

  • Stage 1: Modification to sustain operations for two years (to June 2031) for Longwalls 317 & 318, lodged with the NSW Government in September 2025 and under assessment. 
  • Stage 2: SSD to continue mining west of the current operations and extend the life of the mine beyond to 2044. 

 

The SSD will secure the mine’s future, safely delivering steelmaking coal to Australia’s steel industry and customers overseas. The mine will be able to continue to support local jobs and generate royalty payments that fund essential services across NSW.

 

Key Facts

Metropolitan is a long-standing supplier to Australia’s domestic steel production in the Illawarra region.

Steelmaking coal is a vital ingredient for producing the steel that builds critical infrastructure – from homes and transport networks to hospitals and infrastructure for new energy sources.  

Metropolitan Mine operates approximately 500 metres underground using highly conservative mining layouts designed to prevent and minimise any potential surface impacts.

Frequently Asked Questions

Metropolitan Mine is owned and operated by Peabody, a mining company with more than 140 years’ experience globally and six decades in Australia.

The mine produces metallurgical coal, used in steelmaking.

Metropolitan Mine is located in Helensburgh in the Illawarra region of New South Wales, south of Sydney.

The mine employs approximately 400 local workers.

Mining occurs over 500 metres below the surface, making Metropolitan one of Australia’s deepest and narrowest longwall operations.

A two stage approach:

  • Stage 1 – a Modification to sustain operations for ~2 years (Longwalls 317 & 318), currently
    under assessment.
  • Stage 2 – a future State Significant Development (SSD) application to extend the mine’s life
    to the 2044.

Metropolitan operates under strict regulatory oversight supported by comprehensive environmental monitoring and independent assessments for any proposed changes. To maintain its licences to operate, the operation must continually demonstrate safe, compliant and responsible performance. All environmental, technical and scientific reports submitted to regulators are publicly available as part of the assessment process. Transparent reporting also includes publicly accessible realtime water quality data for Camp Gully Creek, supported by monthly and annual reporting.

Metropolitan operates more than 500 metres underground and uses some of Australia’s narrowest longwall paths to minimise subsidence impacts. Potential impacts are managed through monitoring of water levels, flows and water quality before, during and after mining.

Metropolitan takes its environmental responsibility seriously and is committed to sustainable mining. Specialist surveys and expert reviews assess potential impacts to threatened species including frogs, birds, and bats. Commitments include ongoing monitoring, adaptive management, and offsets where required. Metropolitan has invested close to $1 million in two conservation programs that are reintroducing platypus and the Southern Stuttering Frog to the Royal National Park.
