The United States and Australia have formalized a US$ 3 billion agreement to jointly fund critical minerals projects over the next six months, a move aimed at reducing reliance on Chinese exports of rare earths and other essential materials. The deal, signed by U.S. President Donald Trump and Australian Prime Minister Anthony Albanese on Monday, is part of a broader US$ 8.5 billion project pipeline that will support mining, refining, and technological infrastructure in Australia.
Central to the agreement is the development of a gallium refinery in Western Australia, which will have an annual production capacity of 100 tons. Currently, the U.S. imports about 21 tons of gallium per year, accounting for its entire domestic consumption, according to the U.S. Geological Survey. Gallium is critical for manufacturing blue and violet LEDs, microwave circuits, and high-power lasers, technologies increasingly vital for both commercial and defense applications.
The partnership reflects growing geopolitical concerns over supply chain security. China, which dominates global rare earth production, has recently restricted exports of certain minerals, prompting both governments to accelerate domestic and allied sourcing. Analysts suggest that the deal could strengthen the U.S.’s strategic autonomy in sectors ranging from renewable energy to defense technology.
Alongside mineral development, Australia has committed to purchasing US$ 1.2 billion in autonomous underwater vehicles (AUVs) from American defense startup Anduril. The vehicles, known as Ghost Sharks, are designed to enhance maritime surveillance and defense capabilities. The White House did not clarify whether this is a new procurement or part of a prior US$ 1.12 billion contract announced in September.
Financial experts note that this agreement could signal a broader trend of bilateral investment in critical technology and resource security. With global demand for rare earths and high-tech minerals projected to rise sharply over the next decade, initiatives like this may shape the competitive landscape for U.S. manufacturers and defense contractors while reducing exposure to supply chain disruptions.
