From www.claytonutz.com: The ACCC has advised merger parties to notify under the new mandatory merger regime starting 1 July 2025 to avoid re-notification risks if their acquisitions are not cleared by the end of 2025.

The Treasury Laws Amendment (Mergers and Acquisitions Reform) Act 2024 facilitates this transition, encouraging voluntary notifications to prevent delays and potential costs associated with re-notifying under the new regime after 1 January 2026.

Key provisions include deadlines for informal reviews and merger authorisation applications, emphasizing the importance of timely engagement with the ACCC.
