Australia's population reached 20.4 million in September 2005, according to figures released by the Australian Bureau of Statistics (ABS) this week.
In the year ended September 2005, Australia's population increased by 238,800 people, representing an annual growth rate of 1.2 per cent, consistent with levels recorded in recent years.
Natural increase (the excess of births over deaths) was 129,100 people, contributing to over half (54 per cent) of the total population growth over this period. The remainder of the increase was due to net overseas migration (109,800 people).
All states and territories increased in population, with Queensland experiencing the largest increase (75,100 people) and the Australian Capital Territory the smallest (1,700 people).
