Greensteel Australia’s $500M Investment Returns Steelmaking to the NSW Hunter Region

Australia’s first new steel mill in over 30 years signals the return of domestic manufacturing

$500m all-electric mill is expected to be operational by January 2028, with Stage 2 plans to be announced in the coming weeks.

NEWCASTLE, NSW – 7 July 2026 – Greensteel Australia today announced it has secured the historic 70,000 square metre site at 51 Industrial Drive, Mayfield North, and will invest $500 million to build Australia’s first new steel mill in more than 30 years. The mill will be the first in the country to run entirely on electricity, with no gas used anywhere in the process.

The Greensteel Australia site was home to the BHP Newcastle Steelworks for most of the twentieth century. Greensteel Australia’s investment will return steel manufacturing to the Hunter region.

Greensteel Australia Head of Government Relations, Patrick Buchan, said “The investment was made possible by the recent policy directions set by the NSW and Federal Governments. The Future Made in Australia agenda, together with national and state housing targets and NSW’s support for industry in the Hunter, has given us the certainty we need to manufacture steel in Australia rather than overseas.”
“Australia stopped building steel mills a generation ago. Thanks to the leadership of the NSW and Federal Governments, we’re building again,” Greensteel Australia Chief Executive Officer Romany Ibrahim said. “They’ve made it possible to bring manufacturing home to Newcastle, where Australian steelmaking began and where it never should have left.”

The mill will produce up to 600,000 tonnes of finished steel per year for the housing, transport and energy sectors. Greensteel Australia expects the extra local supply to reduce the construction industry’s reliance on imported steel and, over time, help stabilise and bring down steel prices for Australian builders. Because the process produces no direct CO₂, it will also lower the embodied carbon of Australian construction, supporting state and federal housing targets, including the national goal of 1.2 million new homes.

The heartbeat of this transformation is electric induction furnace technology.

In a traditional mill, steel is heated in massive gas-fired furnaces that are inherently carbon-intensive. Greensteel Australia’s process replaces those fossil-fuel burners with a green solution that prioritises electricity. With its innovative design the mill will tap into renewable energy grids. The significance of this world-leading technology is defined by two critical advantages:

• Zero direct emissions. By using electricity to generate heat, the process produces no direct CO₂.
• Energy independence. The technology gives the facility complete independence from gas supplies, providing a stable, future-proof energy model.

Refurbishment and modernisation at the site will begin before the end of this year. The main equipment, including the world leading, all-electric-induction furnace to be supplied by leading global steel infrastructure group Danieli of Italy, is expected to arrive from October 2027, and the mill is expected to be operational by January 2028.

Steel will be forged at Mayfield, with reinforcing bar the first product and wire rod and coil planned for future stages. The mill will directly employ over 200 direct fulltime staff, including fitters, electricians, crane drivers, metallurgists and engineers, with more jobs created during construction and through Hunter supply chains.

“Every tonne of steel we forge at Mayfield is a tonne Australia doesn’t have to import,” Greensteel Australia Chairman, Ross Garnaut AC, said. “That means more reliable supply and better prices for builders, and because there is no gas anywhere in our process, it also means lower embodied carbon in the homes and infrastructure this country needs. That’s a win for builders and home buyers, and a win for the Hunter.”

Today’s announcement covers Stage 1 of GSA’s plans for Mayfield. A second announcement, covering Stage 2, will be made in the coming weeks. “Mayfield is just the start,” Mr Ibrahim said. “This is Stage 1 – watch this space.”
