Census night was Tuesday 10 August, but it's not too late to participate.
Andrew Henderson, Census Executive Director and National Spokesperson said, "People still have time to complete their Census. We want to make sure everyone is included in the Census so they can help tell their community's story."
Households were sent instructions to help them to complete.
"You can do the Census online, by paper or with help from us. If you can't find, or haven't received your letter, don't worry you can go online and complete your Census without a code.
"There are a range of help and support options for people who need assistance to complete their Census, and you can order a paper form by going to www.census.abs.gov.au or by calling 1800 512 441.
"If we don't hear from you soon, you'll get an overdue notice and/or a visit from our field staff.
"We know most Australians understand that Census isn't just numbers but what those numbers tell us-every stat tells a story. That's why your participation is vital.
"Census data is used to plan and deliver services across Australia. Having the right numbers means the right services can be provided in your community.
"Make sure you're counted in the 2021 Census," Mr Henderson said.
The Census is compulsory. Following letters and visits from Census staff, a person may be fined if they refuse to complete the Census.
