Merger assessment guidelines

Overview

The ACCC is seeking views on draft merger assessment guidelines for the new mandatory merger control regime which commences on 1 January 2026. Businesses may voluntarily notify an acquisition to the ACCC from 1 July 2025.

The merger assessment guidelines outline the analytical framework the ACCC will apply when assessing notified acquisitions under the new regime. It reflects changes resulting from the new regime as well as updates to align with current best practice for competition assessments.

The guidelines are intended to help the community, including merger parties and their advisers, to understand how the ACCC will assess acquisitions under the new regime and provide greater predictability and transparency regarding its decision making.

Following consultation, the ACCC will update the merger assessment guidelines prior to the commencement of voluntary notifications on 1 July 2025.
