Oceania — led overwhelmingly by Australia — is one of the world’s most significant critical minerals jurisdictions, producing approximately 50% of global lithium from spodumene hard rock mines, significant nickel and cobalt from laterite and sulphide deposits in Western Australia, and the world’s largest single rare earth mine at Mount Weld (Lynas Rare Earths). Australia’s geological endowment, stable investment climate, and Five Eyes security alignment make it the most strategically important Western-aligned critical minerals supplier globally. Critical minerals Oceania supply is deeply integrated into Asian — and increasingly Western — battery and defence supply chains, with Australian material flowing primarily to Chinese, Korean, and Japanese processors.
Critical Minerals Overview — Oceania
Australia holds the world’s largest lithium reserves and is the top producer of lithium spodumene concentrate, which is the primary feedstock for Chinese and increasingly Western lithium chemical plants. Western Australia’s Pilbara region hosts the majority of operating lithium mines — including Pilgangoora (Pilbara Minerals), Greenbushes (Talison/Albemarle/Tianqi), and Mt Marion (Mineral Resources/Ganfeng). Australia is also a significant nickel producer from both sulphide deposits (Kambalda, Mount Keith) and laterite deposits (Murrin Murrin, Ravensthorpe), though the 2023–2025 nickel price downturn has led to multiple Western Australian nickel operations being suspended or placed on care and maintenance. Lynas Rare Earths (ASX: LYC) operates Mount Weld, the world’s highest-grade rare earth deposit, processing concentrate at its LAMP facility in Malaysia. Papua New Guinea hosts the Ramu nickel-cobalt laterite mine (Highlands Pacific/Metallurgical Corp of China) and has copper resources in the Star Mountains.

Greenbushes in Western Australia, operated by Talison Lithium (49% Albemarle, 51% Tianqi Lithium), is the world’s largest hard rock lithium mine, with a spodumene concentrate capacity of approximately 1.6 million tonnes per annum at full expansion. Its low-cost, high-grade ore makes it the marginal cost setter for the global lithium spodumene market. The Kemerton lithium hydroxide plant adjacent to Greenbushes — a joint venture between Albemarle and Tianqi — is one of Australia’s first large-scale lithium chemical conversion facilities, targeting 100,000 tonnes of lithium hydroxide per annum at full build.
Major Companies & Projects — Oceania
Pilbara Minerals (ASX: PLS) operates the Pilgangoora lithium-tantalum mine in Western Australia and is one of the world’s largest independent spodumene producers. Lynas Rare Earths (ASX: LYC) is the largest rare earth producer outside China, with Mount Weld mine and the Kalgoorlie rare earth processing facility (under construction) targeting a fully Australian processing chain. IGO Limited (ASX: IGO) holds a 49% stake in the Greenbushes mine and Kemerton processing joint venture via its partnership with Tianqi Lithium. Mineral Resources (ASX: MIN) is a major lithium and iron ore producer with the Mt Marion lithium mine. BHP Group (ASX/NYSE: BHP) operates Nickel West in Western Australia — the only fully integrated nickel supply chain in Australia from mine to battery-ready nickel sulphate — though BHP announced a pause on Nickel West development in 2024 citing market conditions. Glencore (LSE: GLEN) operates the Murrin Murrin nickel-cobalt laterite mine.
Policy, Regulation & Investment Climate
Australia’s Critical Minerals Strategy (2023–2030) and the National Reconstruction Fund provide the policy and financing framework for developing Australia’s downstream processing capability — the stated objective being to move from selling ore and concentrate to producing battery-grade chemicals and refined materials. The Australian government’s Critical Minerals Facility, administered by Export Finance Australia, has committed over $3 billion in concessional financing to qualifying projects. Australia’s Five Eyes membership and bilateral critical minerals agreements with the US, UK, Japan, South Korea, and the EU have created a strong framework for Western-aligned supply chains, including offtake arrangements and processing facility co-investment with allied governments.
The 2023–2025 nickel price downturn — driven by Indonesian supply growth — severely impacted Western Australian nickel operations. BHP, IGO, Wyloo Metals, and Nickel Industries all announced significant operational changes, suspensions, or restructurings. The Australian government has been lobbied for nickel sector support, and domestic content provisions for nickel in future battery supply chain agreements are under discussion.
Oceania in the Global Critical Minerals Supply Chain
Australia is the most commercially important Western-aligned critical minerals supplier globally, but the majority of its output still flows to Chinese processing facilities — particularly for lithium spodumene and nickel concentrates. Redirecting Australian material into Western supply chains requires processing investment in Australia or in allied nations (Japan, South Korea, the US, and Europe), which is happening but at a pace constrained by capital costs, permitting timelines, and the competitive economics of Chinese processing. Lynas’s rare earth processing expansion in Kalgoorlie and the Kemerton hydroxide plant are the most advanced examples of Australian downstream processing investment. The US has signed a Defence Production Act arrangement with Australia specifically covering critical minerals, and Australian producers have signed direct offtake agreements with US automotive OEMs.

What critical minerals does Australia produce?
Australia produces approximately 50% of global lithium from hard rock spodumene mines in Western Australia’s Pilbara region, nickel from sulphide and laterite deposits in Western Australia, cobalt as a nickel by-product, rare earth elements from the Mount Weld mine (Lynas Rare Earths), and smaller volumes of vanadium, tungsten, and manganese. Australia also holds significant undeveloped resources of most critical minerals, making it one of the most important jurisdictions for long-term Western supply chain security.
Which companies lead critical minerals production in Australia?
Key producers include Pilbara Minerals (ASX: PLS) and Talison Lithium (Albemarle/Tianqi) for lithium spodumene, Lynas Rare Earths (ASX: LYC) for rare earth elements, BHP’s Nickel West and Glencore’s Murrin Murrin for nickel, and IGO Limited (ASX: IGO) with integrated lithium and nickel interests. Mineral Resources (ASX: MIN), Allkem/Arcadium, and a pipeline of junior developers are also significant.
Why is Australia so important to the critical minerals supply chain?
Australia combines the world’s largest lithium reserves, significant rare earth, nickel, and cobalt endowment, a stable and transparent investment climate, and close security and trade alliances with the US, UK, Japan, and South Korea. Its Five Eyes membership and bilateral critical minerals agreements make Australian supply the preferred Western-aligned alternative to Chinese-controlled material. The challenge is that most Australian output still flows to Chinese processors — redirecting this into Western supply chains requires significant downstream processing investment in Australia or allied nations.
What happened to Australian nickel mining?
The 2023–2025 nickel price downturn — driven by a rapid expansion of Indonesian HPAL nickel production, predominantly Chinese-financed — severely impacted Australian nickel operations. Battery-grade nickel sulphate prices fell from highs above $30/tonne to below $15/tonne, making several Western Australian operations uneconomic. BHP paused development at Nickel West, IGO closed the Cosmos nickel project, and several smaller operations were suspended. The Australian government is evaluating support measures for the sector, and some analysts project a price recovery from 2026–2027 as Indonesian supply growth moderates.
What is Lynas Rare Earths and why is it important?
Lynas Rare Earths (ASX: LYC) is the world’s largest rare earth producer outside China, operating the Mount Weld mine in Western Australia — the world’s highest-grade rare earth deposit — and processing facilities in Malaysia (LAMP) and Kalgoorlie (under construction). Lynas is strategically critical as virtually the only commercially scaled non-Chinese rare earth supply chain, producing neodymium and praseodymium (NdPr) for permanent magnets and other REE products. The US and Australian governments have provided financing support for Lynas’s processing expansion and a facility in Texas.
What is the outlook for Oceania critical minerals in 2026?
Lithium spodumene production from Australia is expected to remain broadly stable in 2026 after the oversupply-driven curtailments of 2024–2025, with pricing recovery contingent on EV demand growth and Chinese restocking cycles. Lynas’s Kalgoorlie processing facility is expected to reach operational milestones. The nickel sector remains under pressure from Indonesian competition, with recovery timing uncertain. Australia’s downstream processing investment pipeline is progressing, with Kemerton hydroxide and several proposed lithium chemical facilities expected to reach key decisions in 2026. Analysts at Benchmark Mineral Intelligence project Australian lithium chemical capacity to grow from near-zero to meaningful scale by 2027–2028.
