It is estimated that 331,400 people moved interstate during 2009-10. This is an 8% drop from the same period one year ago (359,900 persons), and a 17% drop from the peak interstate migration estimate (398,600 persons) in 2002-03. This decline has put interstate migration for 2009-10 almost at the same level as the 20 year low in 1993-94 (329,600 persons).
Over the 10 years to June 2010, the only states to record average annual net interstate migration (NIM) gains were Queensland (25,900 persons), Western Australia (1,600 persons) and Tasmania (160 persons).
Over the last decade Queensland consistently recorded an annual NIM gain from the rest of the country. However, the gain has gradually declined to be at a 10 year low in 2009-10 with a net gain of 9,600 persons.
The highest population turnover from interstate migration in 2009-10, occurred in the Northern Territory where the gross flows represented 14.1% of the Northern Territory's total population. The Australian Capital Territory also recorded a high population turnover at 10.1% of its population.
