Merger notification screener
Australia's mandatory, suspensory merger regime commenced on 1 January 2026 under the Competition and Consumer Act 2010. Enter the parties' turnover and the transaction value to screen whether the acquisition must be notified to the ACCC — and therefore cannot complete until cleared.
Likely not notifiable on these figures
On the figures entered, no notification limb is met, so the acquisition does not appear to require mandatory notification to the ACCC. This is an indicative screen only.
Creeping acquisitions: Serial / 'creeping' acquisitions of the same or similar businesses are aggregated over a rolling 3-year period. If the parties have made, or plan, related acquisitions, test the thresholds against the aggregated turnover and value.
Recommended action
- Keep a record of the turnover and transaction-value figures relied on to reach this conclusion.
- Re-assess if the figures change or if related acquisitions are made within a rolling 3-year period.
- Confirm the current monetary thresholds with the ACCC / Treasury, as they may have been updated.
Confirm the thresholds: These monetary thresholds are set by regulation / Treasurer determination and may be updated. Confirm the current thresholds and notification requirements directly with the ACCC and Treasury before acting.

Frequently asked questions
- When did mandatory merger notification start in Australia?
- From 1 January 2026 Australia has a mandatory and suspensory merger control regime administered by the ACCC under the Competition and Consumer Act 2010. It replaced the former voluntary informal clearance and authorisation processes. Voluntary notifications were available from 1 July 2025 during the transition.
- What does 'suspensory' mean for my deal?
- A suspensory regime means a notifiable acquisition cannot legally complete until the ACCC has cleared it. Completing before clearance renders the acquisition void and can attract penalties, so notification and the ACCC review timetable must be built into the deal programme.
- What are the notification thresholds?
- Commonly cited 2026 thresholds: a transaction is notifiable if the combined Australian turnover of the parties is at least $200 million AND either the target has Australian turnover of at least $50 million or the global transaction value is at least $250 million. A separate limb captures a very large acquirer (group Australian turnover of at least $500 million) buying a target with Australian turnover of at least $10 million. These figures are set by regulation and may be updated — confirm the current thresholds with the ACCC and Treasury.
- How are serial or creeping acquisitions treated?
- Related acquisitions of the same or similar businesses are aggregated over a rolling three-year period. Individually small deals can therefore combine to cross a threshold, so the thresholds should be tested against the aggregated turnover and transaction value, not each deal in isolation.
