Australia Refines Merger Notification and Control Rules

Recent amendments to Australia’s Competition and Consumer Act alter the consequences for failing to notify a merger, narrow the definition of 'associates' for control purposes, and allow extensions for transaction completions.

Australia’s Parliament has passed targeted amendments to the Competition and Consumer Act, refining the country's mandatory and suspensory merger control regime. The changes address several key areas to reduce unintended consequences for commercial transactions. Most notably, a notifiable acquisition completed without prior notification is no longer automatically void; instead, the Australian Competition and Consumer Commission (ACCC) must apply to the Federal Court for a declaration to void the transaction.

The amendments also narrow the definition of an “associate” for the purposes of determining joint control, meaning ordinary commercial arrangements like minority shareholder protections or arm's-length financing agreements are less likely to trigger a notification requirement. Furthermore, parties who receive ACCC clearance but cannot complete a transaction within the standard 12-month period may now apply to the ACCC for extensions of up to six months. Sophisticated counsel should review upcoming M&A transactions against these new rules, which offer greater certainty and a less severe penalty regime, though the core obligation to notify remains and carries civil penalties. The changes are not retrospective.
