Migrants accounted for over half of Australia's net population increase in the year to March, figures released by the Australian Bureau of Statistics (ABS) show.

The ABS says Australia's population reached 21,283,000 in March - an increase of 1.6 per cent or 336,800 people from the previous year.

There were 430,000 arrivals from overseas during that period, while 230,000 people left Australia.

The net overseas migration to Australia of just under 200,000 accounted for 59 per cent of the country's population.
