Merger Clearance Reforms Hub

Merger control in Australia is set for a major overhaul, moving to a single mandatory and suspensory administrative regime. The new mandatory regime will apply to all deals closing or completing on or after 1 January 2026 (even if signed earlier). The ACCC will be transitioning to the new regime from July 2025, so it's important to start factoring it into transaction timelines now.
Keep across these changes and what they mean for your business and deal pipeline on our one-stop merger reforms hub. We'll be continually updating with new insights and analysis as we transition to the new regime, so check back in to keep up with the latest developments.
