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, particularly the March quarter 2007 movements for private and public sector estimates.

As a result the private and public sector trend estimates have been suspended for Engineering and Construction Work Done for the March quarter 2007.

For more information please see ABS Information Paper: Treatment of Telstra in ABS Statistics (cat. no. 8102.0) released 26 February 2007.

A new chain volume reference year is updated every June quarter. From 2007 onwards the updating of the reference year will be completed in the September quarter each year. In 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.

SIGNIFICANT REVISIONS THIS QUARTER

Compared with the current price original terms estimates published in the previous issue of this publication.

• The December 2006 quarter estimates have been revised upwards by $11.8m for work commenced, downwards by $304.6m for work done and upwards by $296.4m for work yet to be done. These revisions occurred predominantly in 'private for private', 'Roads, highways and subdivisions' in Queensland.
