ABOUT THIS ISSUE

This publication provides an early indication of trends in building and engineering construction activity. The data are estimates based on a response rate of approximately 80% of the value of both building and engineering work done during the quarter. More comprehensive and updated results will be released in Engineering Construction Activity, Australia (cat.no. 8762.0) on 19 January 2012 and in Building Activity, Australia (cat. no. 8752.0) on 18 January 2012.


CHANGES IN THIS ISSUE

A new base year, 2009-10, 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 2009-10, thereby preserving additivity in the quarters after the reference year. Re-referencing affects the levels of, but not the movements in, chain volume estimates. For further information, see the explanatory notes.


DATA NOTES

The trend estimates should be interpreted with caution as the underlying behaviour of building activity may be affected by Government stimulus packages, including the "Building the Education Revolution" (BER) program and Social Housing Initiatives as well as other developments associated with global economic conditions. Re-construction work, following the Queensland and Victorian floods in early 2011 may also have an impact as well as recent volatility in activity caused by large engineering projects. For more details on trend estimates, please see paragraphs 24 to 26 of the explanatory notes.


DATA AVAILABILITY

The output release policy for Building Activity data has been updated effective from the 2011-12 financial year. A full list of data items available via the website or as an information consultancy is provided on the "Downloads" tab of the Construction Work Done, Australia, Preliminary (cat. no. 8755.0) publication.
