ABOUT THIS ISSUE
This publication updates the preliminary estimates released in Construction Work Done, Australia (cat. no. 8755.0) on 28 November 2012. The data in this publication are based on a response rate of approximately 92% of the value of building work done during the quarter. The data are subject to revision when returns from the following quarter are processed. Final data for the September quarter 2012 will be released in the next release of this publication, Building Activity, Australia (cat. no. 8752.0) on 17 April 2013.
CHANGES IN THIS ISSUE
A new base year, 2010-11, has been included 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 2010-11, thereby preserving additivity in the quarters after the reference year. Re-referencing affects the levels of, but not the movements in, chain volume estimates.
A readily printable (PDF) publication is no longer released for this and future issues. Headline data items are presented in HTML format. Data series in the Time Series Spreadsheets are maintained and produced to the same timetable currently in place for this release.
This issue contains the first release of Relative Standard Errors (RSEs) as Data Cubes. These replace tables 38 and 39 from the former readily printable (PDF) publication. See the Data Cubes section under the downloads tab for more details.

SIGNIFICANT REVISIONS THIS ISSUE
Compared to the estimate published in Building Activity, Australia, June quarter 2012 (cat. no. 8752.0) released on 17 October 2012:
Wholesale revisions have been applied to the Value of Building Work Under Construction series as a result of fixing a minor aggregation error. The revisions span the period December 2003 to March 2012 and result in a decrease of approximately 1.0% at the national level.
Several time series spreadsheets for the September quarter 2012 contain 'np' (not available for publication) annotations. This is due to confidential data being contained in these series.
The seasonally adjusted and trend values of Residential Building Work Commenced for the March, June and September 2012 quarters should be interpreted with caution and will be reanalysed for future publications. For more information about seasonal adjustment and trend estimates please refer to paragraphs 22 and 28 of the Explanatory Notes respectively.
The trend estimates should be interpreted with caution as the underlying behaviour of building activity may be affected by Government stimulus packages as well as other developments associated with global economic conditions. For more details on trend estimates, please see paragraphs 28 to 30 of the explanatory notes.
