Thresholds for notifying acquisitions

About thresholds and exemptions

Businesses with an acquisition that meets the notification thresholds must notify the ��ԭ��. Businesses must receive approval or a notification waiver from the ��ԭ�� before the acquisition can proceed.

There are some exemptions which may mean an acquisition doesn’t need to be notified, even when it meets the notification thresholds.

The notification thresholds are set by a Treasury Minister. They are based on Australian revenue and/or global transaction value.

A Treasury Minister may also set additional notification requirements targeted at high-risk acquisitions.

The thresholds apply from 1 January 2026 unless stated otherwise.

Seek legal advice, if you are unsure about whether you need to notify.

Exemptions from notification

Acquisitions that are part of certain internal restructures or reorganisations also fall outside the scope of the merger control regime.

Additional requirements based on voting power

There are additional notification requirements for acquisitions of shares that result in certain changes in voting power, even where they do not result in control of an entity.

These acquisitions are only required to be notified if the general notification thresholds are also met.
