The census also shows 30 per cent of Australians identified as having no religion, compared with 25 per cent in the 2011 census.

Meanwhile, the number of Australians speaking only English at home fell from almost 77 per cent in 2011 to almost 73 per cent in 2016.

England and New Zealand are still the most common countries of birth after Australia, but a growing number are born in China and India.

The census figures, released by the Australian Bureau of Statistics on Tuesday, identified more than 300 languages are being spoken in Australian homes.

After English, the most common languages are Mandarin, Arabic, Cantonese and Vietnamese.

Chief statistician David Kalisch insists the data is high quality, despite the problems that plagued the collection of the information in August when the bureau's online census website crashed.

The census had a response rate of 95 per cent he said, with 63 per cent completing it online.

"The independent assurance panel I established to provide extra assurance and transparency of census data quality concluded that the 2016 Census data can be used with confidence," he said.





"Census data provides a detailed, accurate and fascinating picture of Australia, which will be used to inform critical policy, planning and service delivery decisions for our communities over the coming years."
