CHANGES IN THIS ISSUE
Telstra Corporation was effectively privatised on 20 November 2006. For the purpose of ABS statistics this change from public sector to private sector is effective from March quarter 2007. This change has impacted on the data series presented in this publication, starting with the March quarter 2007 movements for private and public sector estimates.
As a result the private and public sector trend estimates were suspended for Engineering and Construction Work Done for the March quarter 2007. The publication of trend estimates by sector have been reinstated from the June quarter 2007.
For more information please see ABS Information Paper: Treatment of Telstra in ABS Statistics (cat. no. 8102.0) released 26 February 2007.
From 2007 a new chain volume reference year is updated annually in the September quarter each year. For September 2007 the new reference year will be 2005-06 for chain volume estimates. This will result in revisions to growth rates in quarters following 2005-06 but will preserve additivity in those quarters. For earlier periods re-referencing affects the levels of, but not the movements in, chain volume estimates.
