About this release

This publication updates the preliminary estimates released in Construction Work Done, Australia (cat. no. 8755.0) on 10 Nov 2021. This release includes revisions to Engineering Construction data back to June 2021.

Changes this issue

A new base year, 2019–2020, has been introduced into the chain volume estimates which has resulted in revisions to growth rates in subsequent periods. In addition, the chain volume estimates have been re-referenced to 2019–2020, thereby preserving additivity in the quarters after the reference year. Re-referencing affects the levels of, but not the movements in, chain volume estimates.

Data notes

Several time series spreadsheets for recent quarters contain 'np' (not available for publication) annotations. This is due to confidential data being contained in these series.  

Mining projects tend to be complex in structure and comprise a number of different investment activities including exploration, engineering construction, plant and equipment and buildings. A feature article released in the March 2012 issue of Private New Capital Expenditure and Expected Expenditure, Australia (cat. no. 5625.0) provides a summary of the conceptual basis of the relevant ABS publications that measure investment in Australia, using a hypothetical mining project to illustrate how this investment is reflected in ABS data.


For further information about these and related statistics, contact the National Information and Referral Service on 1300 135 070. The ABS Privacy Policy outlines how the ABS will handle any personal information you provide to us.
