China's steel industry is the biggest buyer of Australian iron ore, but its demand is falling and its decarbonization push is changing what it needs. The country missed a 2025 target for electric arc furnace production, yet its government has recommitted to reforming the sector. That puts Australia's dig and ship model at risk. The article lays out the stakes: Australian miners have enjoyed 60% margins, but green iron will cost more and require massive investment. IEEFA estimates AUD 170 billion per year for 14 years to replace metallurgical coal exports with green iron. Australia has renewable resources and some pilot projects, but the transmission, hydrogen, and port infrastructure is not there yet. For anyone tracking steel decarbonization or Australia's export economy, the key question is whether miners will invest in green iron fast enough or lose their main market. The China Australia MOU on steel is still just a policy dialogue, so the commercial path remains uncertain.
