How Wollongong's Steel City Identity Became the Foundation for Australia's Green Energy Gamble

Port Kembla has been making steel since 1928. That fact — more than any policy announcement, more than any ministerial visit — explains why Wollongong is now one of the most consequential industrial sites in the country's shift away from fossil fuels. BlueScope Steel's Port Kembla Steelworks, sprawling across roughly 800 hectares between Springhill Road and the harbour, is the last integrated steelworks operating in Australia. What happens there over the next decade will shape not just the Illawarra economy, but the credibility of Australia's entire industrial decarbonisation program.

The pressure is sharpening in mid-2026 for a specific reason. BlueScope has flagged that its current blast furnace technology will require a major capital decision — reline or replace — before the end of this decade. A blast furnace reline costs upward of $700 million and locks in carbon-intensive ironmaking for another 20 years. The alternative, electric arc furnace technology running on green hydrogen or renewable electricity, is cleaner but commercially unproven at the scale Port Kembla demands. That decision point is now close enough that governments, unions, and investors can no longer treat it as a distant hypothetical.

From the BHP Era to the Green Steel Question

The Illawarra's industrial story runs through two collapses. BHP — which had operated the steelworks for most of the 20th century — sold its flat steel products business to what became BlueScope in 2002, shedding roughly 2,500 jobs in the preceding decade as it restructured. Then in 2011, BlueScope itself stood the No. 6 blast furnace and cut around 1,000 positions in Wollongong, citing an overvalued Australian dollar and collapsing steel margins. The city's unemployment rate spiked above eight percent that year, well above the national average. Suburbs like Warrawong and Cringila, which had built their entire social fabric around shift workers, absorbed the hit hardest.

What survived that period was a leaner but still significant industrial base. Today BlueScope employs approximately 3,500 people directly at Port Kembla, with thousands more in the local supply chain. The University of Wollongong, whose engineering and materials science faculties have long maintained research ties to the steelworks, estimates the steelworks complex generates around $2 billion annually in regional economic activity. That dependency is precisely what makes the green steel transition so fraught: the Illawarra cannot afford to get it wrong, and neither can any government that wants to claim a serious industrial climate policy.

The federal government's $15 billion National Reconstruction Fund, established in 2023, listed green metals as a priority sector. Port Kembla's proposed Renewable Energy Zone — anchored around the harbour's deep-water port infrastructure on Foreshore Road — is designed to receive and distribute offshore wind energy from the proposed Illawarra Offshore Wind Zone, which covers about 1,400 square kilometres of ocean south of the city. The Australian Energy Market Operator has included the Illawarra zone in its step-change scenario for reaching 82 percent renewables nationally by 2030. None of that infrastructure exists yet. The offshore wind projects are still working through federal environmental approvals.

What the Next Phase Looks Like

The Illawarra Shoalhaven Regional Development Fund, administered through the NSW government's Regional NSW department, has directed funding toward transition planning, workforce retraining, and business diversification across the region since 2022. Wollongong City Council's own economic development strategy, updated in 2024, explicitly names green steel and clean energy manufacturing as priority industries for the Crown Street Mall precinct's broader economy — an acknowledgement that even the city centre's retail health is downstream of what happens at the steelworks.

Residents and workers watching the process should understand that the key decision windows are converging. BlueScope's blast furnace capital call, the federal government's offshore wind regulatory process, and the buildout of transmission infrastructure linking the Port Kembla zone to the national grid are all on roughly the same five-year clock. Community consultations on the offshore wind environmental impact statement are expected to open later in 2026. Industry groups including the Illawarra Business Chamber have been pushing for those sessions to include explicit workforce transition modelling — not just energy output projections. The Steel City did not arrive at this moment accidentally. A century of decisions about where to put blast furnaces, who to employ, and which technologies to back has produced exactly this crossroads.
