From sladen.com.au: In January 2025, significant reforms to Australia’s Mergers and Acquisitions regulatory landscape were established, moving from a voluntary review process to a mandatory one overseen by the ACCC).

The reforms require certain transactions to be notified to the ACCC prior to completion, with specified thresholds guiding the notifications, and introduce a penalty regime for non-compliance.

These changes aim to promote competition and will take effect for transactions completed after January 1, 2026, with voluntary notifications accepted starting July 1, 2025.
