a. Includes Other Territories comprising Jervis Bay Territory, Christmas Island, the Cocos (Keeling) Islands and Norfolk Island.

State and territory population change is comprised of natural increase, net overseas migration, and net interstate migration (interstate arrivals minus interstate departures).

Components of annual population change

For the year ending 30 September 2021:

natural increase was the major contributor to population change in New South Wales, South Australia, Western Australia, Tasmania and the Australian Capital Territory
net interstate migration was the major contributor to population change in Queensland and the Northern Territory.
net overseas migration was the major contributor to change in Victoria.

Notes

COVID-19

Statistics in this release are impacted by the COVID-19 pandemic and the resulting Australian Government closure of the international border from 20 March 2020.

To ensure the ongoing production of fit-for-purpose official population estimates through the COVID-19 pandemic, the ABS has been assessing the likely impact of changed traveller behaviour on preliminary overseas migration estimates, a component of ERP. The ABS has introduced more frequent revisions to overseas migration to ensure the suite of demographic statistics continue to be of high quality and reflect the most timely data available. Preliminary overseas migration estimates will be revised every quarter over four quarters, instead of once after four quarters, until it becomes final. These more frequent revisions will ensure the most timely and accurate data flows through to ERP.

For further information see the Information Paper: Improvements to estimation of net overseas migration (cat. no. 3412.0.55.004).
