Overseas migration estimates are final for years up to and including 2007–08 and preliminary for 2008–09. See paragraphs 9–10 of the Explanatory Notes for further information.
This time series is based on the improved methodology (12/16 month rule) from 2004 onwards. It has been used in calculating Australia's official estimated resident population (ERP) since September quarter 2006. As a result a break in the NOM time series exists from the 2006–07 financial year. Caution should be taken when comparing estimates over time. For further information see paragraphs 22 to 32 of the Explanatory Notes and the Technical Note - Improved Methods for Calculating Net Overseas Migration from September quarter 2006 and onwards available soon under the Explanatory Notes tab with the electronic release of this publication.
