    What is FIRB?

    FIRB · Foreign Investment Review Board

    Quick answer

    The Australian body that reviews acquisitions of land and mining interests by foreign persons. Approval is routine for most commercial transactions, but foreign government investors are reviewable regardless of value and critical minerals draw closer scrutiny.

    Key points

    • The Treasurer decides on a national interest test, not the Board.
    • Foreign government investors are reviewable regardless of value.
    • Build it into the timetable, not into the conditions after signing.

    What FIRB does

    The Foreign Investment Review Board advises the Australian Treasurer on acquisitions by foreign persons under the Foreign Acquisitions and Takeovers Act. It does not itself approve transactions; the Treasurer decides, on a national interest test.

    Mining tenements and interests in Australian land — which includes mining tenements — fall squarely within the regime, so most inbound mining transactions require consideration.

    What triggers review

    Monetary thresholds apply and vary by the investor’s country of origin, because free trade agreement partners receive higher thresholds. Below the applicable threshold, no approval is required for an ordinary commercial acquisition.

    Two categories override that. Foreign government investors are reviewable regardless of value, which captures state-owned enterprises and sovereign funds and any entity in which they hold a substantial interest. And national security land and businesses attract mandatory notification separately.

    Critical minerals and timing

    Critical minerals receive closer scrutiny than they did a decade ago, reflecting Australian policy on supply chains. Approvals in that space take longer and more often carry conditions.

    The practical consequence is scheduling. FIRB should be built into the transaction timetable from the outset rather than treated as a post-signing formality, and conditions precedent should reflect the realistic review period.

    Frequently asked questions

    Does every foreign mining investment in Australia need FIRB approval?
    No. Monetary thresholds apply and vary by the investor’s country. But foreign government investors are reviewable regardless of value, and national security categories carry mandatory notification.
    Why do thresholds differ by country?
    Because Australia’s free trade agreements provide higher thresholds for investors from partner countries. The applicable figure depends on the investor’s origin and the type of asset.
    How are critical minerals treated?
    With closer scrutiny than ordinary commercial mining acquisitions, reflecting supply chain policy. Reviews take longer and conditions are more common, so the timetable should allow for it.
