📌 Key Takeaways
- Australia will fast-track a A$1.2 billion critical minerals stockpile, targeting rare earths, antimony and gallium.
- The reserve is designed to secure supply for Australia and its allies, not maximise short-term returns.
- The move comes as China tightens export controls, reinforcing Western supply chain vulnerability.
- Canberra is aligning its strategy with U.S., G7 and allied stockpiling efforts, without making it the policy’s centrepiece.
Australia is accelerating plans to build a national critical minerals stockpile, bringing forward the launch of a A$1.2 billion reserve as governments race to protect supply chains for defence, semiconductors and clean energy technologies.
The policy, announced by the Australian government this month, will initially focus on rare earth elements, antimony and gallium, minerals where global supply is heavily concentrated and geopolitically exposed.
The reserve is expected to be operational by late 2026, earlier than originally planned.
Why Australia is moving now
The decision follows a sharp escalation in global supply risks.
China dominates production or processing of many critical minerals, including:
- ~80% of global gallium supply, used in semiconductors and radar systems.
- ~70% of rare earth mine production and up to 90% of downstream processing, critical for magnets used in EVs, wind turbines and defence systems.
“From defence applications to clean manufacturing, critical minerals are at the heart of our economic and national security,” says Minister for Resources Madeleine King. “The Strategic Reserve’s initial focus on antimony, gallium and rare earths will give added certainty to Australian projects, help attract further investment and help the sector deal with potential future market disruptions.”
Beijing has tightened export controls on several of these materials since 2023. In mid-2025, Chinese exports of certain rare-earth magnets to the U.S. fell by more than 90% year-on-year, after licensing rules were expanded.
Australian officials say the stockpile is designed to absorb shocks, not speculate on prices.
How the stockpile will work
Unlike traditional physical reserves, Australia’s model will rely heavily on offtake agreements and financial backing rather than warehouses filled with ore.
Under the plan:
- The government will use its export finance agencies to secure offtake rights from domestic producers.
- Material can be on-sold to allied governments or manufacturers during supply disruptions.
- Part of the funding may be used for direct purchases if markets tighten.
Treasurer Jim Chalmers said the reserve would prioritise supply security and industrial resilience, even if it does not generate near-term financial returns.
Strategic context, not just domestic policy
Australia’s move mirrors a broader shift among Western governments.
- The United States has expanded its National Defense Stockpile and invoked the Defense Production Act to support critical mineral supply chains.
- The European Union is pushing member states to hold strategic reserves equivalent to at least 10% of annual consumption for selected critical raw materials by 2030.
- Japan and South Korea have increased state-backed stockpiling following earlier Chinese export restrictions.
Canberra has confirmed that Australia’s stockpile will be accessible to allies, reinforcing its role as a preferred supplier outside China.
Why it matters
Critical minerals are no longer treated as ordinary commodities.
They sit at the intersection of:
- National security
- Energy transition targets
- Industrial policy
By fast-tracking its stockpile, Australia is signalling that supply reliability now outweighs market efficiency in strategic minerals.
For policymakers, the message is clear: dependence on single-country supply chains is no longer acceptable. For markets, the signal is more subtle — government intervention is becoming a permanent feature of critical mineral pricing and availability.
