Collie Steel Mill Receives Final Construction Approval

We are pleased to announce that Green Steel of WA has now secured all necessary regulatory and statutory approvals required to commence construction of The Collie Steel Mill, Australia’s first green steel mill. The approvals process was completed in under two years, thanks to the project’s recognition as a Strategic Project by the WA Government and the generous support of the Cook Government, which includes funding commitments from the Collie Industry Attraction and Development Fund. This streamlined process combined with the great efforts of the project team and our partners. has helped fast-track one of the most significant local manufacturing developments in Western Australia’s recent history.

“My government is committed to delivering a Just Transition for Collie and establishing major new industries in town. Establishing a green iron and steel industry in WA is a key focus of our Made in WA plan, and Collie’s Green Steel Mill will kickstart this new industry. Hitting these key milestones is another step forward to securing Collie’s future as a major new industrial hub,” Premier and State Development Minister, Roger Cook.

With Front-End Engineering Design (FEED) completed, and the business case and financial model finalised, this milestone confirms the feasibility of the project and represents a significant step forward in delivering Western Australia’s first steel recycling mill—and Australia’s first green steel facility.

Currently, 100% of Western Australia’s rebar is imported, exposing the state to global supply chain risks, trade uncertainty, and tariffs. The Collie Steel Mill will change that — producing 450,000 tonnes per year of low-emissions rebar using locally sourced WA scrap steel. This product will support critical infrastructure across the state, including wind turbines, transmission towers, housing, and broader construction projects.

As a key initiative under the Cook Government’s “Made in WA” vision, the project will play an important role in re-shoring essential manufacturing, strengthening economic resilience, and demonstrating how sustainable, locally produced materials can support the infrastructure of tomorrow.

With approvals secured and feasibility confirmed, the project now moves toward finalising commercial contracts, concluding project financing, and achieving Final Investment Decision, leading to the commencement of construction in 2025.

Once delivered, the Collie Steel Mill will establish long-term sovereign steelmaking capability, create regional jobs, and ensure a secure, low-emissions steel supply for Western Australia.
