Under NBN Co’s Special Access Undertaking, NBN Co must lodge a replacement module application covering the regulatory cycle after 2026.

On 1 July 2024, the ACCC provided notice to NBN Co specifying that the due date for lodging its replacement module application is 2 July 2025. The ACCC also provided a request for information and documents in support of NBN Co’s application.

NBN Co is required to consult with access seekers and consumer advocacy groups regarding relevant expenditure proposed during that regulatory cycle before lodging its application.

The ACCC will assess the replacement module application lodged by NBN Co. The ACCC will consult with stakeholders, assess the proposal, and make a replacement module determination based on its assessment.

The replacement module determination establishes a set of access terms and conditions for the upcoming regulatory cycle (of between 3-5 years). It will also address the other matters that will be raised in NBN Co’s replacement module application.

The ACCC will make its replacement module determination at least 20 business days before the last day of the current regulatory cycle (30 June 2026), unless extended by up to 6 months.
