Parliamentary inquiry to put critical minerals in the spotlight - Australian Mining

A parliamentary inquiry will examine Australia's critical minerals supply chain, putting focus on the mineral inputs required for the energy transition. The inquiry reflects growing concern about Australia's capacity to secure and process the materials needed for renewable energy systems and battery storage.

Where this fits

This touches the materials pressure directly. Australia has the ore deposits for many critical minerals, but processing capacity and supply-chain sovereignty remain weak. A renewables-heavy transition requires vast quantities of lithium, cobalt, nickel and rare earths, while a nuclear grid's material footprint is small and front-loaded. The minerals needed for solar panels, wind turbines, battery banks and grid-scale storage are also the minerals China dominates in refining and processing, creating a chokepoint on grid buildout and a dependence that sits uneasily alongside national security.

What it means

Every megawatt of renewable capacity Australia builds depends on supply chains where China holds processing leverage. Battery storage, the proposed solution to weather-dependent output, compounds that dependence: a 100 GWh battery bank needs processed lithium, cobalt and nickel sourced largely through Chinese refineries. An inquiry into critical minerals is overdue, but without domestic processing capacity and long-term offtake agreements, it risks becoming a fact-finding exercise rather than a pathway to energy sovereignty. The minerals argument cuts both ways: Australia's energy transition is locked into a supply relationship with a strategic rival, while a firm, low-material alternative remains legislatively banned.
