About this issue

This publication updates the preliminary estimates released in Construction Work Done, Australia. The data in this publication are based on a response rate of approximately 85% of the value of building work done during the quarter, which is lower than the long term response rate average. The data are subject to revision when returns from the following quarter are processed. Final data for the September 2025 quarter will be released in the next release of this publication, Building Activity, Australia on 8 April 2026.

Several time series spreadsheets contain 'np' (not available for publication) annotations from the September quarter 2012 onwards. This is due to confidential data being contained in these series.
