Operational optimisation and project expansions to drive Australia’s lithium supply in 2026

Industry Overview - Australia is the world's largest lithium producer, accounting for 33.5% of global lithium output in 2025, with production estimated at 113,500 tonnes, reflecting a 1.8% growth over 2024 [1] - The growth in lithium production is supported by the ramp-up of Liontown Resources' Kathleen Valley project and SQM's Mt Holland lithium project, which began operations in mid-2024, along with expansions at Pilgangoora and Greenbushes operations [1] Market Dynamics - Weak spodumene prices and cost-cutting measures have led several producers to scale back operations, including PLS Group Limited, Mineral Resources, and Rio Tinto Lithium, highlighting a strategic shift towards capital preservation and operational rationalization [2] - Shutdowns of key projects indicate a response to the current pricing downturn, with operations at Ngungaju, Bald Hill, and Mount Cattlin being suspended [2] Future Projections - Australia's lithium output is expected to rebound in 2026, with a projected growth of 6% to reach 120,300 tonnes, driven by operational enhancements and capacity expansions at key mining sites [3] - The Kathleen Valley project is set to significantly contribute to this growth following its transition to a fully underground operation, targeting higher-grade ore and improving operational efficiency [3] Expansion Activities - Continued expansion at Greenbushes and Pilgangoora projects is anticipated to materially contribute to overall supply growth through 2026, reinforcing Australia's position in the global lithium market [4] Government Initiatives - The Australian Government is promoting investments in the critical minerals industry through the Critical Minerals Strategy 2023–2030 and the "Future Made in Australia" plan, which includes funding and tax incentives [5] - The release of the Critical Minerals Prospectus in February 2026 profiles 78 investment-ready projects, including lithium projects, and lists midstream processing opportunities related to lithium [6]
