New Dawn – transitional period for the new Australian merger regime commences

Orange Abstract waves

    What you need to know

    • Just in time for the start of the transitional period to the new merger regime, Treasury has finalised a notification instrument setting out important details about the new merger regime, including the notification thresholds, targeted notification requirements, notification forms and fees.
    • The final instrument contains some limited but significant changes to an earlier exposure draft of the instrument released for consultation on 28 March 2025.

    What you need to do

    • Understand the potential impact of the final instrument on your business. Don't wait until 1 January 2026 to engage as the instrument is relevant to deals notified voluntarily under the new regime starting from 1 July 2025.
    • If you intend to seek informal clearance from the ACCC before 1 January 2026, ensure you do so no later than early October 2025 and much earlier if possible to avoid the possibility of not obtaining informal clearance by 31 December 2025 and having to re-notify under the new regime.

    The Australian business community has anticipated the publication of the final merger notification thresholds for some months. Following extensive consultation by Treasury, those thresholds were published on 30 June 2025, only one day before companies can start voluntarily notifying mergers to the ACCC under the new regime (although the date of the instrument is 24 June 2025).

    In most cases, the changes made to the final determination instrument from the draft published in March 2025 are helpful, and resolve uncertainties posed by the draft instrument. In particular, the use of annual turnover based on audited financial statements to determine whether filing thresholds are satisfied aligns Australia's regime with overseas counterparts, and the inclusion of additional exceptions to the thresholds helps close some gaps in the draft instrument.

    There are, however, important issues that remain with respect to the acquisition of interests in land, and the published filing fees for Phase 2 mergers in particular are high relative to most overseas jurisdictions. Real concerns remain as to whether the new regime will dampen deal making – parties are effectively required to commit to the full Phase 2 fees before understanding issues raised in market inquiries. Mid-size and smaller deals with marginal economics could be most at risk of falling over because of the size of the Phase 2 filing fees. The impact of these aspects of the regime on merger activity and deal certainty in Australia will be closely observed in the upcoming months.

    In this article, we have highlighted the key features of the final determination, and the changes introduced from the consultation draft. For further details of the new merger regime, please refer to our earlier article.

    General notification thresholds

    The monetary figures for the notification thresholds remain unchanged from the draft instrument, although there have been some changes to definitions and other aspects of the tests, including the relevant measure of revenue (discussed further below).

    Acquisitions of shares and assets will trigger mandatory notification requirements if they reach any of the turnover thresholds described below and there is a connection to Australia – either because the target company of a share acquisition carries on business in Australia, or because the target asset is used in or forms part of a business carried on in Australia.

    CircumstanceAll corporate groupsVery large corporate groups
    Acquisitions resulting in large or larger corporate groups / Acquisitions by very large corporate groups

    An acquisition is notifiable if:

    • the combined Australian revenue of the acquirer (including its connected entities) and the target is at least $200 million, noting that this can be satisfied by one party only; and
    • either:
      • the target's Australian revenue (if a share acquisition), or the Australian revenue attributable to the target asset (if an asset acquisition), is at least $50 million; or
      • the global transaction value is at least $250 million.

    An acquisition is notifiable if:

    • the acquirer's Australian revenue (including connected entities) is at least $500 million; and
    • the target's Australian revenue (if a share acquisition), or the Australian revenue attributable to the target asset (if an asset acquisition), is at least $10 million.
    Creeping or serial acquisitions (3-year look back)

    When calculating the target's Australian revenue, the calculation must include:

    • the Australian revenue from the current acquisition, plus
    • the cumulative Australian revenue from any other acquisitions over the previous 3 years that predominantly involves supplying or acquiring the same, substitutable or otherwise competitive goods or services (disregarding geographic factors or limitations) except for previous acquisitions with less than $2 million in Australian revenue and acquisitions that were previously notified

    Additional notification thresholds: Class determination for supermarket businesses

    In addition to the above notification thresholds, an acquisition will be required to be notified to the ACCC if it belongs to a class of acquisitions determined by the Minister.

    The instrument contains a class determination for acquisitions of supermarket businesses, and land for supermarket businesses, by major supermarkets (Coles Group Limited, Woolworths Group Limited, and their connected entities).

    Key changes from the draft instrument

     Proposed in draft instrumentFinal position
    Basis for turnover thresholdsCurrent GST turnover. The draft instrument referred to "current GST turnover" which had the meaning given by the A New Tax System (Goods and Services Tax) Act 1999 (Cth).Australian revenue. "Current GST turnover" has been replaced with "Australian revenue", which is so much of the entity's gross revenue, determined in accordance with accounting standards, for the entity's most recently ended 12-month financial reporting period, that is attributable to transactions or assets within Australia, or transactions into Australia.
    Meaning of "connected entity"
    Associated entities and controllers. The draft instrument treated the connected entities of parties to a transaction as including entities controlling the parties, and "associated entities" of the parties as defined in section 50AAA of the Corporations Act 2001 (Cth). This is a broad provision which captured entities over which the parties themselves exert control, and entities in which the parties have a qualifying investment and a significant influence over it. The draft instrument proposed that different interpretations of "control" would apply for different limbs of this test.

    Related entities and controllers. The associated entity test has been replaced with a more limited test: now the following entities are "connected entities":

    • related bodies corporate of the parties; and
    • entities controlled by, controlling, or which have a controller in common with, the parties.

    Control is consistently interpreted to include joint control by associates; control exercised by special purpose vehicles; and control exercised by subsidiaries.

    Meaning of "connected with Australia"
    Carries on a business in Australia or intends to carry on a business in Australia.
    Carries on a business in Australia. The words "intends to carry on a business in Australia" have been removed.
    Attribution of revenue to assets for turnover thresholds
    N/A. The draft instrument did not clarify how current GST turnover should be attributed to assets.

    Fallback attribution - 20% of the market value of the asset. While no general rules for attributing revenue to assets are stated, a fallback rule is provided: to the extent that it is not reasonably practicable to attribute the Australian revenue of a target to an acquisition of an asset, the amount to be included is instead 20% of the market value of the asset.

    This rule is not one that merger parties can choose to apply or disregard at their discretion – it is only applicable where the "not reasonably practicable" requirement is met. The explanatory statement for the final instrument suggests the acquisition of a lease may meet this requirement.

    This results in the unusual outcome that the acquisition of a leasehold interest over premises, or potentially a freehold interest in vacant land, may or may not be notifiable depending on the rental amount and term negotiated between landlord and tenant, or the price agreed to be paid for the vacant land.

    Relevant acquisitions for serial acquisitions threshold
    Involves the same or substitutable goods or services. The draft instrument stated that the serial acquisition threshold is intended to capture previous acquisitions involving the same or substitutable goods or services as the proposed acquisition.
    Predominantly involves the same or substitutable goods or services. The word "predominantly" has been added to the instrument. The explanatory statement to the instrument states "predominantly" is intended to take its ordinary meaning ("chiefly; principally; for the most part"). An example the explanatory statement gives is that fuel outlets predominantly supply fuel to consumers, and the incidental sale of snacks and drinks would not make this business relevant to future acquisitions of convenience stores. Geographic factors or limitations are disregarded.
    Point in time for serial acquisitions threshold test
    Unclear. The draft instrument was unclear on how turnover should be calculated for acquisitions in the previous three years, but may have required acquirers to calculate current GST turnover (at the time of their proposed acquisition) for historical acquisitions.
    Contract date for the previous acquisition. The instrument clarifies that the revenue to be attributed to a past acquisition, for the purposes of the serial acquisitions threshold tests, should be calculated at the contract date for the previous acquisition.
    Exemptions for land acquisitions

    Land acquisitions for a purpose other than operating a commercial business on the land. The draft instrument proposed that the following acquisitions would be exempt from notification:

    • land acquisitions made for the purpose of developing residential premises; and
    • acquisitions by businesses primarily engaged in buying, selling or leasing land, where the acquisition is for a purpose other than operating a commercial business on the land.

    Land acquisitions for a purpose other than operating a commercial business on the land that is not ancillary or incidental to the primary purpose. The final instrument clarifies that the exemptions extend to operating a land development or management business, including operating a commercial business ancillary or incidental to the primary purpose of buying, selling, leasing or developing land.

    The scope of what is "ancillary" or "incidental" remains to be worked out in practice.

    Lease extensions and renewals
    Exemption for lease extensions and renewals. Extensions or renewals of leases for land upon which a commercial business is currently being operated was proposed to be exempt from notification.
    Exemption for lease extensions and renewals. All extensions and renewals of leases for land will be exempt from notification – the instrument removes the qualifier "upon which a commercial business is currently being operated".
    Other exemptions for certain land acquisitions
    N/A.

    New exemption for subsequent acquisitions of the same interests in land. A new exemption covers acquisitions of legal or further equitable interests in land where the same acquirer has previously notified the ACCC of an acquisition of an equitable interest in the same land. This is an important exception which will prevent parties who enter into agreements for lease (AFL) having to re-notify the subsequent entry into the lease itself, and will avoid the uncertainty that could otherwise arise in the event of any changes to the market in the period between the AFL and the final lease.

    However, the exception only applies where the entry into the AFL or other previous acquisition was notified to the ACCC, which means that protection does not extend to any AFLs entered into prior to the introduction of the merger regime. Companies who have existing AFLs but are not likely to enter the final lease by 31 December 2025 will need to consider whether the entry into the lease will trigger a mandatory notification at that time.

    New exemption for sale and leaseback arrangements. Sale and leaseback arrangements relating to land (typically used for financing or capital management purposes) are exempt from notification.

    New exemption for land development rights. Acquisitions of land development rights (including a right to develop or redevelop land, and rights to construct, refurbish, expand or subdivide existing land buildings) are also exempt if the acquisition of an interest in the underlying land would be exempt from notification.

    Financial securities
    Equity-traded derivatives. The draft instrument proposed an exception to notification for acquisitions of equity-traded derivatives, but not other derivatives.
    Acquisitions of any types of derivatives. These are exempt from notification so long as they do not provide the acquirer control of an entity or have the effect that the acquirer will acquire all or substantially all of the assets of a business.
    Financial market infrastructure
    N/A.

    Clearing and settlement facility activity and acquisitions under close out, set off, or account combination rights. The final instrument provides that acquisitions in the ordinary course of clearing and settlement activities will not be notifiable.

    There are also exemptions to notification for acquisitions that occur as a result of the exercise of a contractual right to close out a transaction, or the exercise of a right of set off or combination of accounts under the contract. However, these exemptions do not apply if the acquisition provides the acquirer control of an entity or have the effect that the acquirer will acquire all or substantially all of the assets of a business.

    Debt and security instruments
    Security instruments acquired in the ordinary course of a business of providing financial accommodation. The draft instrument exempted acquisitions of security interests acquired in the ordinary course of a business of providing financial accommodation from notification.
    Other security instruments. In addition to the exemption for providers of financial accommodation, the final instrument provides an exemption for acquisitions of debt instruments and interests, and security interests, so long as they do not provide the acquirer control of an entity or have the effect that the acquirer will acquire all or substantially all of the assets of a business.
    Notification fees
    Single phase 2 fee. The draft instrument did not contain information on notification fees. However, Treasury's cost recovery fees consultation paper considered flat fees for waiver applications ($8,300), phase 1 assessments ($56,800), phase 2 assessments ($952,000) and public benefits applications ($401,000).

    Tiered phase 2 fees. The notification fees set out in the instrument for waivers, phase 1 assessment and public benefits applications remain unchanged.

    However, there are now tiered fees for phase 2 reviews based on the greater of either the market values of the shares and assets being acquired, or the consideration received:

    • $50 million or less – $475,000 fee;
    • more than $50 million, but not more than $1 billion – $855,000 fee; and
    • more than $1 billion – $1,595,000 fee.
    Notification forms
    N/A.

    Changes to the short form and long form. In both forms the instruments adds requirements to describe any vertical relationships or other overlaps between the parties, describe the main industries in which the parties supply relevant goods and services, provide any supply or other ancillary agreements that are conditional on the acquisition, and provide an organisation chart or diagram that shows the structure of ownership and control of the parties involved in the supply of relevant goods or services both before and after the acquisition. The forms also clarify that the requirement to provide contact details for competitors and customers apply to each party to the acquisition.

    Changes to the long form. The requirements to provide details of the sales process undertaken in relation to the target and details of alternative proposals have been removed. The requirement to describe factors influencing entry into the market for the supply of the relevant goods or services now extends to descriptions of the importance of economies of scale and scope, and of network effects, for production or distribution. The timing of board documents required to be provided has also been updated to documents within two years (previously three years) before the date of notification.

    Next steps

    From 1 July 2025 to 1 January 2026, the new regime is operational on a voluntary basis (though notification fees are still payable for voluntary notifications and reviews will still be published on ACCC website).

    The ACCC is still accepting applications for informal clearance, but is less likely to finalise informal clearance applications received from late September/early October before the new regime takes effect. Outstanding applications for informal clearance may require re-notification under the new regime once 1 January 2026 arrives, so businesses contemplating transactions should give careful thought to whether to notify their deal voluntarily under the new regime before 1 January 2026.
