Under the current framework, failure to properly comply with the new mandatory Merger Control Regime will automatically void a transaction. The Government has indicated that it plans to amend these automatic voiding provisions while still maintaining incentives for compliance with the mandatory notification requirements.

Mandatory Merger Notifications Are Coming
Compliance & Corporate, Corporate & Commercial

Australia’s new mandatory merger control regime is on the horizon. From 1 January 2026, certain transactions must be notified to the Australian Competition and Consumer Commission (ACCC) and cleared before completion.

A voluntary opt-in period is now open and runs until 31 December 2025. This is a critical window to plan ahead.

These changes represent the most significant shift in Australian merger control in decades. Proactive planning will be critical to avoid costly delays and surprises.
