Overseas migration estimates are final for years up to and including 2009-10. 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.
NOM data excludes foreign diplomatic personnel and their families. Foreign diplomatic personnel and their families are considered out of scope for ERP purposes and have been removed from NOM and the traveller characteristics database.
NOM arrivals are all overseas arrivals that contribute to net overseas migration. They are the number of incoming international travellers who stay in Australia for 12 months or more and are added to the population.
NOM departures are all overseas departures that contribute to net overseas migration. They are the number of outgoing international travellers (Australian residents and long term visitors to Australia) who stay away from Australia for 12 months or more and are subtracted from the population.
For further information see paragraphs 28 to 44 of the Explanatory Notes and the Technical Note: '12/16 month rule' Methodology for Calculating Net Overseas Migration from September quarter 2006 and onwards released with this publication.
The figures in this data cube have been rounded to the nearest 10. As a result, sums of the components may not add exactly to totals. Rounded figures and unrounded figures should not be assumed to be accurate to the last digit shown. Analysis featured in the publication is based on unrounded data. Calculations made on rounded data may differ to those published.
The visa type information in this tale represents the visa at the time of a traveller's specific movement. It is this specific movement that has been used to calculate NOM. Therefore, information on visas granted are unlikely to match figures based on NOM as seen in this table.
