The New ACCC Merger Regime — What You Need to Know
From 1 January 2026, Australia's merger control regime changed significantly. Qualifying transactions must now be notified to the ACCC and cleared prior to completion. Sierra Legal has been at the forefront of advising clients on these changes. If you are planning an acquisition, we can help you determine whether your transaction requires notification and guide you through the process.

Frequently Asked Questions
What does an M&A lawyer do?
An M&A lawyer helps clients buy, sell, merge and invest in businesses. That includes sale preparation, due diligence, structuring, drafting and negotiating transaction documents, managing confidentiality and disclosure, handling regulatory issues, and guiding the deal through to completion.
How long does an M&A transaction typically take?
The timeline varies depending on the complexity of the transaction. A straightforward business acquisition may take 6–12 weeks from heads of agreement to completion. More complex transactions involving regulatory approvals or multiple parties can take several months.
Do I need to notify the ACCC about my acquisition?
From 1 January 2026, mandatory notification thresholds apply to certain transactions. The thresholds are based on the combined Australian revenue of the parties and the transaction value. Sierra Legal can quickly assess whether your transaction requires notification.
What is vendor due diligence?
Vendor due diligence involves a seller commissioning a legal review of their own business before going to market. This allows issues to be identified and resolved early, reducing the risk of deal delays or price adjustments during the buyer's due diligence process.
Does Sierra Legal advise on cross-border M&A transactions?
Yes. We have experience advising on cross-border transactions and can assist with FIRB approval requirements for foreign investment into Australia.
