FIRB approval is a statutory authorisation required under Australian federal law for certain acquisitions by foreign persons, including interests in residential land, commercial property, businesses, and sensitive assets. It is not a procedural formality and does not depend on commercial rationale, financial capacity, or representations made by third parties. This regime operates independently from state-based buyer incentives such as first home buyer grants, which are governed by separate revenue legislation and do not displace FIRB obligations.
From a legal standpoint, FIRB approval operates as a pre-transaction compliance requirement. The obligation arises automatically where legislative thresholds are met, and failure to obtain approval before acquiring an interest may result in mandatory divestment, substantial civil penalties, or criminal liability.
FIRB approval is a formal authorisation issued under the Foreign Acquisitions and Takeovers Act 1975 (Cth), permitting a foreign person to acquire a specified interest in Australian land, businesses, or assets.
Legally, FIRB approval:
Approval is granted by the Treasurer, following advice from the Foreign Investment Review Board, but legal responsibility for compliance remains with the investor. Buyers who are uncertain about their classification or obligations should find a property lawyer before entering into any binding arrangements.

FIRB approval is required because Australian federal law mandates government oversight of certain foreign acquisitions to protect the national interest. This requirement is imposed by the Foreign Acquisitions and Takeovers Act 1975 (Cth) and applies automatically where a foreign person seeks to acquire a regulated interest in Australian land, businesses, or assets.
Legally, the FIRB regime exists to control foreign participation in sectors affecting housing supply, economic stability, national security, and strategic infrastructure. Approval allows the Treasurer to assess proposed acquisitions, impose enforceable conditions, or prohibit transactions that may be contrary to Australia’s national interest. Without this statutory approval, the acquisition itself is unlawful, regardless of commercial intent or financial capacity.
FIRB approval is legally required for any person classified as a “foreign person” under Australian law who seeks to acquire a regulated interest in Australian property, land, or assets. This obligation arises automatically under the Foreign Acquisitions and Takeovers Act 1975 (Cth) and is not dependent on visa duration, intention to reside, or investment purpose.
Under the legislation, a foreign person includes non-citizens, temporary visa holders, foreign corporations, and entities controlled by foreign individuals. These persons must obtain approval before acquiring residential real estate, certain commercial land, agricultural land, or interests above prescribed thresholds. Failure to obtain approval renders the acquisition unlawful and exposes the purchaser to compulsory divestment orders, civil penalties, and criminal sanctions.
Residential property acquisitions are one of the most tightly regulated categories under FIRB legislation.
Foreign persons may generally obtain approval to acquire:
Approvals are commonly granted subject to resale, occupancy, or development conditions.
Acquisition of established dwellings is generally prohibited unless:
Failure to comply may result in forced sale, regardless of whether the purchase was connected to using grant to buy apartment or other assistance schemes.
The FIRB approval process must occur before acquisition of the relevant interest.
Legally required steps include:
Entering into an unconditional contract without approval may itself constitute a breach.

Decision periods are set by legislation and generally range from 30 to 90 days, depending on transaction complexity.
The Treasurer may:
Timeframes are suspended where further information is requested.
Application fees are imposed by regulation and vary according to:
Fees are non-refundable and payable regardless of outcome.
Some acquisitions require FIRB approval regardless of value, particularly in residential land.
Thresholds differ based on:
Incorrect reliance on thresholds is a common compliance error.
Exemptions are narrowly defined and include:
Exemptions must be confirmed legally; assumptions carry risk.
Failure to obtain FIRB approval where required may result in:
Liability may arise even where non-compliance was inadvertent.
FIRB approval regulates foreign investment control. ACCC approval regulates competition and market concentration.
They are separate legal regimes and may both apply to a single transaction.

The FIRB framework prioritises legal certainty and enforceability over transactional flexibility. It reflects a deliberate legislative choice to anchor compliance obligations at the federal level.
Foreign investors are expected to assess approval requirements proactively, not retrospectively.
Before addressing common questions, it is critical to note that FIRB obligations arise automatically under statute.
A legal authorisation required for certain foreign acquisitions under Australian law.
Approval must be obtained before acquiring the interest. Conditional contracts may still trigger obligations.
No. Retrospective approval is not permitted.
Yes. Breach of conditions may result in penalties or divestment.
No. Approval applies only to the approved transaction.
FIRB approval is a substantive legal requirement, not an administrative step. It imposes obligations before acquisition and continues to regulate conduct after approval is granted.
