Release dates for forthcoming issues have been changed to allow for the use of additional data in the calculation of improved preliminary net overseas migration (NOM) estimates. For further information see Information Paper: Improving Net Overseas Migration Estimation, Mar 2010 (cat. no. 3412.0.55.001).


Data for 30 September 2001 to 30 June 2006 are final and based on the 2006 Census of Population and Housing. Data for 2006-07 and 2007-08 financial years have been revised and data from 30 September 2008 onwards are preliminary. For further information see paragraph 7 of the Explanatory Notes.

Due to the collection and estimation methods applied to produce preliminary statistics, users should exercise caution when analysing and interpreting the most recent annual and quarterly estimates for all components of the estimated resident population (ERP), particularly when making time series comparisons.


Changes in this issue are as follows:
  • Scheduled annual revisions for 2007-08 financial year for births, deaths, natural increase, net overseas migration (NOM), estimated resident population (ERP), total fertility rates (TFR), standardised death rates (SDR) and infant mortality rates (IMR).
  • Previously published preliminary NOM estimates for September quarter 2008 to June quarter 2009 have been updated with improved preliminary NOM estimates. Preliminary NOM estimates for September quarter 2009 were compiled using the improved methods. For further information see paragraphs 14-15 of the Explanatory Notes.


Regional Population Growth, Australia, 2008-09 (cat. no. 3218.0) will be released on 30 March 2010.

Household and Family Projections, Australia, 2006 to 2031 (cat. no. 3236.0) will be released on 8 June 2010.
