How Australia is Positioning Itself as an Alternative to China’s Critical Mineral Earth Dominance

Introduction

Australia is using allied capital to build a domestic mining-to-processing supply chain that serves Japanese manufacturing, U.S. defense procurement, and its own industrial ambitions.

On May 4, Australian Prime Minister Anthony Albanese and Japanese Prime Minister Sanae Takaichi signed a Joint Declaration on Economic Security Cooperation in Canberra, elevating critical minerals to “a core pillar” of their bilateral relationship. Australia agreed to commit up to AUD 1.3 billion and Japan has invested roughly AUD 370 million. The deal is part of a larger framework in which Australia and the United States committed USD 1 billion from each side toward a USD 8.5 billion pipeline of joint critical minerals projects in October 2025.

Australia’s Reliance on China

Australia historically has exported the majority of its minerals to China for refinement. Over the past two decades, China became the dominant refiner for many of Australia’s raw materials such as iron ore, coal, natural gas, lithium, and more. This trade relationship transformed Australia into a critical supplier of raw materials to the Chinese economy, particularly during the commodity boom of the 2000s and early 2010s. However, while Australia exported large quantities of mineral feedstock, much of the downstream refining and processing capacity remained concentrated in China, leaving Australia heavily dependent on external industrial supply chains despite its resource abundance.

Why Australia is Moving Away From China

The Australia-China relationship has deteriorated since 2020, when Beijing imposed punitive tariffs and informal trade restrictions on Australian wine, barley, beef, coal, and lobster in response to political disagreements. Furthermore, in April 2025 when China imposed export restrictions on seven rare earth elements, it directly affected Australia, a downstream consumer of processed materials it could not produce domestically. Later in 2025, Beijing escalated further, requiring foreign companies to obtain Chinese government approval for any exported products containing as little as 0.1% of rare earth material of Chinese origin or produced with Chinese technology.

Analysts at the Center for Strategic and International Studies describe Chinese supply behavior as deliberate market manipulation, flooding markets with excess supply to push prices low enough that mines in countries like the U.S. and Australia become unviable. Lynas, an Australian miner, nearly went bankrupt during a Chinese price suppression cycle in the mid-2010s and was rescued by Japanese capital through JARE (Japan Australia Rare Earths).

China’s export restrictions have increased costs across advanced manufacturing supply chains reliant on processed rare earth inputs. China has a near monopoly. Like the United States, countries around the globe are taking critical minerals supply as a national-security issue.

Australia Domestic Build-Out

Australia is also developing its own supply chains. It has dominated the upstream segment of the critical minerals supply chain through the extraction of rare earths, lithium, iron ore, and bauxite, but it lacks midstream and downstream capabilities. In response, Australia is increasingly investing in domestic processing, separation, and strategic manufacturing capacity to reduce reliance on Chinese supply chains and build a more vertically integrated critical minerals industry.

It has invested over AUD 2 billion. Lynas Rare Earths began heavy rare earth production in 2025, adding separated terbium and dysprosium output to its existing operations. Iluka Resources is constructing a rare earth refinery in Western Australia with AUD 1.1 billion in government backing, scheduled to open in 2026.

Australia has also established a Critical Minerals Strategic Reserve with AUD 1.2 billion to secure rights over antimony, gallium, and rare earth elements produced in Australia. The government has identified 31 critical minerals eligible for processing incentives and is targeting 40–60% domestic processing capacity across priority minerals.

A Two-Front Allied Strategy

The May 4 Japan is part of a larger structure that began with the October 2025 U.S.–Australia Framework for Securing of Supply in the Mining and Processing of Critical Minerals and Rare Earths. The two governments have since provided over USD 3 billion in combined financing for joint projects. The U.S. Export-Import Bank has issued seven letters of interest totaling USD 2.2 billion to support Australian projects, including RZ Resources, Arafura Nolans, and Lynas.

The trilateral partnership became explicit on March 14, 2026, when senior representatives from Australia, the United States, and Japan held the inaugural Mining, Minerals, and Metals Investment Ministerial in Tokyo. Resulting from the conference was a new Critical Minerals Supply Security Response Group. Co-led by the U.S. Department of Energy and Australia's Department of Industry, Science, and Resources, it was established to coordinate priority minerals and supply chain vulnerabilities across the three countries.

Where the Minerals Go

The six projects named in the May 4 Joint Statement tie directly into Japan’s most strategically important manufacturing sectors, particularly semiconductors, batteries, and advanced industrial materials.

These projects are not random mining investments; each targets a specific bottleneck in allied manufacturing supply chains. For example:

• The Alcoa Gallium Recovery Project in Western Australia is expected to produce around 10% of global gallium supply. Gallium-based semiconductors are used in radar systems, telecommunications equipment, LEDs, and solar panels.
• Lynas’s heavy rare earth operations produce dysprosium and terbium, minerals essential for high-performance permanent magnets used in EV motors and wind turbines.
• The Ardea Kalgoorlie Nickel Project, backed by Sumitomo Metal Mining and Mitsubishi Corporation, supplies nickel and cobalt for battery manufacturing.
• Magnium Australia’s high-purity magnesium project targets lightweight materials used in the automotive and aerospace sectors.

The same minerals also feed Australian and U.S. demand. For example, a single nuclear-powered submarine that Australia and the U.S. plan to co-build requires approximately 4.5 tons of rare earth and other critical minerals. In October 2025, Lynas signed a memorandum of understanding with the U.S.-based Noveon Magnetics– the only American manufacturer of permanent magnets, to develop a scalable U.S. magnet supply chain anchored on Australian feedstock.

Australia is evolving from a raw exporter into a strategically integrated allied industrial supplier

Our View

Australia's transition will take time. Projects target first production in 2026–2028, and even at full capacity, the combined Australian-Japanese-U.S. pipeline of roughly USD 13 billion across the two frameworks remains small relative to the global critical minerals market.

Arafura at 5% of global rare earths and Alcoa at 10% of gallium are meaningful but partial offsets against Chinese dominance, which still controls roughly 90% of rare earth processing and 92% of magnet production. The more probable near-term outcome is not displacement but bifurcation: a separate Western pricing tier for processed minerals, supported by government offtake guarantees and price floors, operating in parallel to the Chinese-dominated global market. Australian projects benefit from this structure because allied buyers will pay premiums to avoid exposure to China.

The main risk is execution. Critical mineral projects often run over budget and face delays, while China can still flood global markets with supply to drive prices lower and pressure Western competitors. This happened in March 2026 when Albemarle withdrew from its planned South Carolina lithium refinery project after lithium prices fell more than 80% from their 2022 highs, making the project economically unviable. Had it been completed, the Mega-Flex facility would have been one of the largest lithium hydroxide refineries outside China and Australia.

Whether allied governments can sustain price-support mechanisms long enough for projects to become commercially viable will determine if Australia's build-out becomes the backbone of an allied supply chain or another underutilized capacity stranded inside a Chinese-controlled market.
