Australia's proposed amendments to its mandatory merger control regime aim to address problematic features that have led to over-capture of unproblematic deals in the first six months of operation. The changes introduce a court-supervised 'voidable' model replacing automatic voiding, clarify the 'control' exemption to reduce capture of benign minority acquisitions, and allow parties to extend ACCC approvals beyond the 12-month mark.

Proposed amendments to Australia's mandatory merger control regime seek to address some of the most problematic features of the new regime, which have resulted in highly conservative approaches to notifiability and contributed to a substantial over-capture of unproblematic deals in the first six months of its operation. While the changes will not affect the monetary thresholds for notification, they mitigate the consequences of missed notifications. 

On 2 July 2026, the Australian Government introduced what it describes as 'targeted refinements' to the merger control provisions of the Competition and Consumer Act 2010 (Cth) (CCA), tucked away in a schedule to the Treasury Laws Amendment (Strengthening Accountability for Tax Adviser Misconduct and Other Measures) Bill 2026 (Bill).

Australia Moves To Ban Unfair Non-competes, No-poach Agreements, And Wage-fixing Arrangements

The Australian government is consulting on legislation that would treat certain employment-related restrictive covenants and inter-business labor market agreements as cartel conduct, while banning other clauses outright. The proposed bill extends Australia's cartel framework to no-poach and wage-fixing provisions between any employers, and prohibits non-compete clauses for most employees, with severe penalties for non-compliance including fines and potential jail time for individuals.
