New Capital Expenditure, in Volume Terms

• The trend volume estimate for total new capital expenditure rose 8.2% in the September quarter 2011 while the seasonally adjusted estimate rose 12.3%.
• The trend volume estimate for buildings and structures rose 11.3% in the September quarter 2011 while the seasonally adjusted estimate rose 17.1%.
• The trend volume estimate for equipment, plant and machinery rose 3.4% in the September quarter 2011 while the seasonally adjusted estimate rose 6.3%.

• This issue includes the fourth estimate (Estimate 4) for 2011-12.
• Estimate 4 for 2011-12 is $158,032m. This is 26.9% higher than Estimate 4 for 2010-11. Estimate 4 is 5.1% higher than Estimate 3 for 2011-12.
• See pages 7 to 10 for further commentary on expectations data.

• Each September quarter the reference and base year for chain volume estimates for the Survey of Private New Capital Expenditure are updated. A new base year, 2009-10, has been introduced into the chain volume estimates which has resulted in minor revisions to growth rates in subsequent periods. In addition, the chain volume estimates have been re-referenced to 2009-10. Additivity is preserved in the quarters of the reference year and subsequent quarters. Re-referencing affects the level of, but not the movements in, chain volume estimates.
  
• As happens each year, a seasonal re-analysis has been undertaken based on estimates up to and including the June quarter 2011. No significant changes have occurred this re-analysis, resulting in only minor revisions to the seasonally adjusted estimates.
