Australia's population has surged to more than 27 million as births and migrants arriving outstrip deaths and residents leaving the nation.
The Australian Bureau of Statistics population clock tipped over the mark on Wednesday and continues to increase by one person every 50 seconds.
The nation's population grew by 624,100 people or 2.4 per cent last year, with net overseas migration of 518,100 people and natural growth of 106,100 new citizens.
It's projected to reach between 29.2 and 30.8 million people by 2032, and between 34.3 and 45.9 million people by 2071.
That's based on the population increasing by an annual average of between 1.2 per cent and 1.7 per cent until June 2032.
The estimate of 27 million citizens is based on the nation's population on June 30 last year, which was 26,638,544 people, and projected growth that includes a birth every one minute and 42 seconds.
It also assumes that a person dies every two minutes and 52 seconds and a migrant arrives to live in Australia every 45 seconds.
That's almost triple the amount of residents leaving to live overseas, with the ABS estimating that one person departs the nation every two minutes and 43 seconds.
On June 30, 2022, when the population was about 26 million people, the bureau estimated 18.3 million residents were born in Australia and 7.7 million were born overseas.
