What could a Trump deal on critical minerals mean for Australia – and could MAGA be a sticking point?

October 20, 2025

Australia’s vast reserves of lithium, rare earths, cobalt and other critical minerals have become strategic assets in the global contest for supply chain security. As the US seeks to reduce dependence on China for defence, clean energy and advanced manufacturing materials, Canberra is courted as a reliable partner. Yet this opportunity carries complications: Australia exports nearly 90% of its lithium to China, its top trading partner, creating a delicate diplomatic tightrope. Prime Minister Anthony Albanese’s upcoming White House meeting offers a chance to strengthen Aukus and secure trade terms, but risks triggering economic retaliation from Beijing. The proposed $1.2 billion critical minerals stockpile presents a potential solution, though questions remain about its design and effectiveness amid competing national interests.

Key takeaways

Australia’s critical minerals reserves are globally significant, positioning it as a key potential partner in US efforts to reduce dependence on Chinese supply chains.
The proposed $1.2 billion critical minerals stockpile offers a tangible negotiation tool but remains undefined in key aspects such as mineral composition and timeline.
Despite its strategic value to the US, Australia’s extensive economic ties to China – particularly for lithium exports – create exposure to potential retaliation if perceived as aligning too closely with Washington.
The MAGA focus on domestic manufacturing may limit US enthusiasm for investing in Australian downstream processing, even as such capacity is vital for Australia to move up the value chain.
Success in this arena will require Australia to balance alliance commitments with economic pragmatism, avoiding over-reliance on any single partner while pursuing long-term industrial resilience.

Why Critical Minerals Matter Now More Than Ever

Critical minerals – including lithium, rare earth elements, cobalt and manganese – power EV batteries, renewable energy infrastructure and military hardware such as jets, submarines and drones. As green energy and defence modernization accelerate, demand has surged. China controls approximately 70% of rare earth mining and over 90% of processing, giving it significant influence over global prices and availability. Recent export restrictions have heightened Western fears of supply disruption, prompting the US to pursue alternatives. For the US, securing reliable access is a national security imperative; dependence on a strategic competitor for defence materials creates unacceptable vulnerability. Washington actively seeks to 'decouple' from China in this sector, seeking trusted allies with substantial reserves to partner in mining and, ideally, processing.

Australia’s Position as a Key Supplier

Australia produces roughly half of the world’s lithium and about a quarter of global bauxite, alongside significant cobalt, manganese and rare earths. However, like many resource-rich nations, it exports most minerals in raw form – primarily to China – for offshore refining and manufacturing. This 'dig-and-ship' model limits domestic value capture. Recognising this, the government has pursued downstream processing incentives. The 2023 federal budget introduced a 10% tax credit for critical minerals processing, commencing July 2027, to attract investment and build domestic capability. Despite this ambition, downstream capacity remains limited. The proposed stockpile, while significant, is primarily a security reserve rather than an industrial transformation foundation. Its success depends on US engagement and whether it catalyses broader investment in Australian refining and manufacturing.

The Proposed Stockpile: A Bargaining Chip with Limits

Central to Australia’s discussions with the Trump administration is offering access to the proposed $1.2 billion critical minerals strategic reserve. Announced in April as a response to Trump’s 'Liberation Day' tariffs, it aims to secure access to high-strategic-value minerals. However, key details – including mineral composition and timeframe – remain under industry consultation. A recent Department of Prime Minister and Cabinet brief, shared with stakeholders and viewed by Guardian Australia, shows composition decisions are unresolved, inviting input on suitability across two, five and ten-year horizons. The government envisions US and allied investors accessing supplies, potentially under a taxpayer-backed 'price floor' to mitigate volatility, mirroring US efforts to counter China’s export controls. While the stockpile is a tangible negotiation asset, experts caution it may not fully address US desires for supply chain resilience. Susan Park, Professor of Global Energy Transition at the University of Sydney, notes the reserve focuses on access security rather than downstream value addition – a limitation affecting appeal to American partners seeking comprehensive partnerships.

The China Factor: Economic Interdependence and Strategic Risk

Any deepening of Australia’s critical minerals partnership with the US must contend with China being Australia’s largest trading partner. In 2023–24, bilateral trade exceeded A$280 billion, with iron ore, coal and increasingly critical minerals as core exports. Approximately 90% of Australia’s lithium exports – projected to be worth A$8.2 billion annually by 2030 – flow to Chinese refiners and battery manufacturers. This interdependence creates vulnerability to potential Chinese retaliation. History offers precedent: in 2020, China imposed tariffs and restrictions on Australian barley, beef and wine following calls for an independent Covid-19 origins inquiry. While critical minerals have not yet been targeted, analysts warn Beijing could leverage its processing dominance to disrupt Australian exports if it perceives Canberra as aligning too closely with US strategic goals. Treasurer Jim Chalmers has sought to reassure markets, stating Australia will engage with major trading partners 'in good faith' and in accordance with national economic interests, emphasising that balancing relations with both the US and China is not only possible but necessary. However, this dual engagement requires careful calibration to avoid appearing to favour one over the other in a way that provokes economic countermeasures.

Could 'Maga' Be a Sticking Point in Negotiations?

Beyond economics, political ideology may complicate deeper US-Australian cooperation on critical minerals. Professor Park highlights the 'Make America Great Again' (MAGA) agenda as a potential obstacle to agreements involving downstream processing in Australia. The Trump administration’s emphasis on reshoring manufacturing and prioritising domestic job creation could make it politically difficult to support significant investment in Australian processing facilities, even if economically rational. From a MAGA perspective, value-adding activities overseas – regardless of alliance status – may be viewed as undermining the goal of revitalising American industry. This tension underscores a broader challenge in allied supply chain initiatives: aligning national interests across borders. While the US seeks secure and diversified critical mineral sources, its preference may lean toward developing processing capacity within its own borders or under direct American control, rather than enabling allied nations to capture more value upstream. For Australia, this raises a strategic question: can it offer sufficient security and reliability to satisfy US concerns without sacrificing its own economic aspirations or becoming merely an extractive supplier in a China-US duopoly? The answer may determine whether the partnership delivers lasting benefit or remains a tactical, short-term arrangement.

What this means

Australia stands at a pivotal moment in its economic and strategic development. The global scramble for critical minerals has transformed its natural resources into instruments of diplomacy, offering both opportunity and risk. While the proposed stockpile and ongoing dialogue with the United States present a chance to strengthen the Aukus alliance and secure favourable trade terms, the path forward is fraught with complexity.
