About this release

This publication updates the preliminary estimates released in Construction Work Done, Australia (cat. no. 8755.0) on 23 Feb 2022. This release includes revisions to Engineering Construction data back to September 2021.

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.
