Australia and U.S. Establish Critical Minerals Partnership
The United States and Australia have formalized an agreement aimed at bolstering critical minerals projects, representing a strategic move to secure supply chains amidst increasing global competition. The deal, announced on Monday, October 20, 2025, will see a combined investment of $3 billion from both nations into a range of projects deemed vital for technological advancement and national security. The total project pipeline is valued at $8.5 billion, signaling a substantial commitment to the sector.

Securing Critical Mineral Supply Chains
The agreement underscores growing concerns over the concentration of critical mineral production in specific regions, particularly as some countries have begun to restrict exports of these essential resources. Rare earth elements and gallium, for instance, are crucial components in electronics manufacturing and electric motors. The U.S. currently imports 100% of its gallium, approximately 21 tons annually, according to the U.S. Geological Survey. This dependence creates vulnerabilities that the new partnership seeks to address.
As part of the initiative, the U.S. Department of Defense will invest in a gallium refinery located in Western Australia. This refinery is projected to have a production capacity of 100 tons per year, significantly reducing U.S. reliance on foreign sources. Gallium’s applications in microwave circuits and blue and violet LEDs, which are used in powerful lasers, highlight its strategic importance across various industries.
Defense Sector Collaboration
Beyond the critical minerals agreement, Australia has also committed to purchasing $1.2 billion worth of autonomous underwater vehicles (AUVs) from Anduril, a defense startup. While the White House has not confirmed whether this purchase is a new agreement or part of a previously announced $1.12 billion program, it indicates a deepening collaboration between the two nations in defense technology. The earlier program involved Anduril delivering a fleet of Ghost Shark AUVs to the Australian Navy, announced in September 2025.
Market Analysis: Critical Minerals Industry Trends
The global market for critical minerals is experiencing rapid growth, driven by the increasing demand for electronics, electric vehicles, and renewable energy technologies. Restrictions on exports from major producing countries have amplified concerns about supply chain security, leading governments worldwide to prioritize diversification and domestic production. The Australia-U.S. agreement reflects this trend, aiming to establish a more resilient and geographically diverse supply chain.
The investment in a gallium refinery in Western Australia represents a significant step towards reducing dependence on a single source for this critical mineral. This strategic move is likely to encourage further investments in critical mineral processing and refining capabilities in other regions, fostering competition and innovation within the industry. Companies involved in the extraction, processing, and manufacturing of products using critical minerals are expected to benefit from these developments.
Geopolitical Implications and Future Outlook
The partnership between Australia and the U.S. carries significant geopolitical implications, signaling a united front in securing access to critical resources. This collaboration is expected to strengthen the strategic alliance between the two nations and encourage similar partnerships with other countries that share concerns about supply chain vulnerabilities. The focus on gallium and rare earth elements highlights the specific minerals that are considered most critical for technological advancement and national security.
Looking ahead, the success of the critical minerals projects will depend on factors such as project execution, technological innovation, and regulatory support. The long-term impact of the agreement will be determined by its ability to foster a sustainable and diversified supply chain that can meet the growing demand for these essential resources. Further investments in research and development, as well as collaboration between industry, government, and academia, will be crucial for ensuring the long-term competitiveness of the critical minerals sector.
In conclusion, the $3 billion critical minerals deal between Australia and the United States represents a strategic initiative to secure supply chains and foster collaboration in the technology and defense sectors. By investing in domestic production and diversifying sources of critical minerals, both nations aim to mitigate risks and ensure access to the resources needed for future economic growth and national security.
