The bulletin intends to provide insights to Consultants in the preparation of their cost estimates to better inform their project estimates in which the NTA is the approving authority.
The bulletin is updated annually, or earlier if the macroeconomic conditions continue unstable.
The latest version of the bulletin was published in May 2025, replacing the February 2024 bulletin and supplementary notes. It should be used to provide guidance to Sponsoring Agencies on the treatment of future inflation from May 2025 onwards.
