Once every five years, Australia effectively takes a national photograph.

Not a photograph of buildings or landscapes, but of us.

Where we live.

How old we are.

Where we were born.

What languages we speak.

What work we do.

How we travel to work.

What our homes are like.

And numerous other details that collectively help describe what Australia has become.

The 2026 Census of Population and Housing takes place on Tuesday 11 August 2026.

For most Australians, participating should be straightforward.

But what exactly are we being asked to do, why does government need the information and what happens to it afterwards?

Here is The Times guide to the 2026 Australian Census.

When is the 2026 Census?

Census night is Tuesday 11 August 2026.

The Census is conducted by the Australian Bureau of Statistics and occurs every five years.

The basic idea is to establish a snapshot of Australia at a particular point in time.

Importantly, the Census is concerned with where people are on Census night as well as where they usually live.

Everyone in Australia on Census night must be included on a Census form, including visitors and visa holders.

That includes people on Norfolk Island, Christmas Island and the Cocos (Keeling) Islands.

Do I have to wait until Tuesday night?

Not necessarily.

The ABS says households that have already received their Census instructions can complete the form before Census night if they know where everyone will be on Tuesday night.

Most households have been receiving instructions through the mail.

The ABS expects approximately 85 per cent of Census forms to be completed online in 2026.

How do I complete it?

The 2026 Census is being conducted on a digital-first basis.

Most households receive a letter containing a Census number and temporary password allowing them to complete the form online.

Paper forms remain available.

Some households, particularly in areas where the ABS expects a greater need for paper forms, may have received one directly.

The ABS says an average household should take around 30 minutes to complete the Census.

People requiring assistance can also obtain help from the ABS, including accessible options and in-person assistance in various locations.

Who goes on my Census form?

The general principle is simple:

Include everybody who is staying at your address on Census night.

That includes babies, children and visitors.

If somebody who normally lives in your household is away on Census night, the Census asks for information identifying them as temporarily absent.

That person should be included on the Census form for wherever they actually are in Australia on Census night.

This is one reason the Census can appear slightly different from an ordinary household survey.

It is trying to establish both where people are and where they normally live.

What if I am travelling?

You still count.

The Census is not restricted to Australians sitting in their usual homes.

If you are elsewhere in Australia on Census night, you should be counted where you are staying.

That is part of creating the national snapshot.

Visitors and visa holders who are in Australia are also included.

Is the Census compulsory?

Yes.

Participation in the Australian Census is compulsory.

The Census operates under federal legislation, including the Census and Statistics Act 1905.

If a person does not complete the Census, the Australian Statistician can issue a written direction requiring them to provide the information.

Failure to comply with such a direction can result in prosecution and a fine.

The practical message is much simpler:

If you receive Census instructions, complete the Census.

What does the Census ask?

There are 66 questions on the 2026 Census form, organised across topics including address, household members, personal details, cultural background, education, employment, income, housing and other characteristics.

The Census collects information including:

age;

place of birth;

ancestry;

language;

religion;

education;

employment;

occupation;

income;

housing;

family and household relationships;

long-term health conditions;

and travel to work.

Taken individually, many questions can appear mundane.

Taken together across millions of Australians, they become an extraordinarily detailed picture of the country.

What is new in 2026?

There are several changes.

One of the most significant is the introduction of new questions on gender and sexual orientation for people aged 16 years and older.

The Census also asks about a person's sex recorded at birth.

For the new gender and sexual-orientation questions, respondents can select “prefer not to answer.”

The ABS says the information is intended to improve data about Australia's population and assist planning of health and community services.

The Census does not use the terms “cis”, “trans” or “gender diverse” in the questions themselves.

What does the sexual-orientation question ask?

For people aged 16 and older, the Census asks how the person describes their sexual orientation.

The response options include straight, gay or lesbian, bisexual, another term, don't know and prefer not to answer.

This is the first Australian Census to collect this information nationally.

What about religion?

The religion question remains.

Importantly, answering the religion question is optional.

“No religion” is one of the available responses.

The ABS has retained the general question design used for the 2021 Census while updating some instructional material.

The information is useful for understanding the changing religious composition of Australia and can assist governments and organisations planning services.

Ancestry is changing too

Australians increasingly have complex family backgrounds.

For 2026, respondents can report up to four ancestries, compared with two previously.

That potentially provides a more detailed picture of Australia's cultural composition.

In a country shaped by generations of migration, that is useful information.

Why does Australia conduct a Census at all?

This is the most important question.

Australia needs to know how many people live here and where they live.

Government decisions involving billions of dollars depend on population information.

Census data helps inform planning for:

schools;

hospitals and healthcare;

roads;

public transport;

housing;

community services;

local infrastructure;

and numerous other government and community functions.

It also helps determine how government funding is distributed between states and territories and contributes to decisions concerning electoral boundaries.

The Census is therefore considerably more important than a national exercise in curiosity.

Imagine planning a suburb without it

Suppose an outer suburban area has experienced enormous population growth.

There are more children.

More young families.

More people travelling to work.

More demand for healthcare.

More homes.

Government needs evidence of those changes.

How many classrooms might eventually be required?

Where is public transport demand increasing?

Where is an ageing population likely to require additional services?

Where are new communities emerging?

Which areas are growing and which are shrinking?

Census information helps answer those questions.

Without reliable population information, governments would be planning infrastructure partly in the dark.

Businesses use Census information too

The value extends beyond government.

Businesses can use Census data to understand potential markets.

Where are young families living?

Which communities are ageing?

Where are household incomes changing?

Which suburbs are growing?

Where are new migrants settling?

What occupations dominate particular regions?

Where might demand for particular goods or services develop?

A retailer considering a new location, a property developer assessing an area or a healthcare provider planning a service can all potentially learn something from Census data.

Small communities matter

One of the particular strengths of the Census is geographic detail.

Many surveys can tell us something about Australia nationally.

The Census can tell us about much smaller areas.

That matters enormously in regional and rural Australia.

A national statistic can conceal substantial differences between Cairns, Noosa, Sydney, Hobart, Broken Hill and a remote community.

The Census allows Australia to examine itself at a much finer level.

What happens to my personal information?

Privacy is understandably one of the most common concerns.

The ABS says information supplied on Census forms is confidential and will not be released in a way that identifies an individual or household.

Census information is not collected for compliance or enforcement purposes.

The ABS uses names and addresses for purposes including processing forms, avoiding duplicate counting, producing geographic statistics and approved statistical research.

According to the ABS, names from Census forms are retained for up to 18 months after the Census, while addresses may be retained for up to three years.

Statistical information continues to be retained and used after identifying information has been removed or separated according to ABS processes.

What is the Census Time Capsule?

There is an unusual optional feature of the Census.

Australians can choose to have their Census information transferred to the National Archives of Australia for preservation for 99 years.

The information cannot then be accessed during that period.

Information from the 2026 Census Time Capsule will not become available until 2125.

For people interested in family history, it is fascinating to consider.

Someone more than a century from now could potentially learn about the household you live in today.

Participation in the Time Capsule is optional.

When will we see the results?

Do not expect Australia's new demographic portrait immediately.

Processing information from an entire country takes time.

The ABS plans to release 2026 Census information in stages.

The first major release is scheduled for June 2027, covering most Census topics.

A further release, including employment-related information, is planned for October 2027.

Remaining information, including data concerning the distance people live from their workplaces, is expected in early 2028.

That is when the 2026 Census begins becoming an enormous public resource for journalists, researchers, governments, businesses and communities.

Why accurate answers matter

A Census becomes valuable because millions of individual answers become one national dataset.

One inaccurate form will not transform Australian public policy.

But widespread inaccurate or incomplete information diminishes the quality of the picture.

The objective is therefore not to provide the answer you think government wants.

It is to answer accurately.

The Census is intended to describe Australia as it actually is.

That includes its strengths, problems, diversity and change.

Australia will look different from 2021

Perhaps the most interesting part of every Census is comparison.

Australia in 2026 is not Australia in 2021.

The population has grown.

Migration has changed communities.

Housing costs have transformed where some Australians can afford to live.

Working from home has altered employment patterns.

Regional populations have changed.

The population has aged.

Religious affiliation continues to evolve.

Household structures are changing.

New questions will reveal characteristics previous Censuses could not measure adequately.

When the results begin arriving in 2027, we will be able to see those changes in extraordinary detail.

The Times View

The Census can feel like another government form arriving in the mailbox.

It is considerably more important than that.

For one night every five years, Australia attempts to count almost everybody and record enough information to understand who we are, where we live and how the country is changing.

Those answers eventually influence decisions about schools, hospitals, transport, housing, electoral boundaries, community services and billions of dollars of public expenditure.

The 2026 Census also creates something less tangible.

A record of Australia at this particular moment in its history.

Census night is Tuesday 11 August 2026.

Complete it accurately.

Because individually the questions are about you and your household.

Collectively, the answers are about Australia.

Beware of census scams

Australian banks are warning households to be on the look-out for Census related scams as criminals look to get their hands on personal and financial information.

Key tips for staying Census safe:

    Never click a link in a text or email claiming to be from the ABS.

    Double check you are on the official Census website before proceeding.

    Remember, the ABS will never ask for banking details such as login details or any kind of payment.

    If you're unsure about any Census communications, visit the official ABS website to contact them directly.

    If you think you’ve provided information to a scammer, contact your bank immediately.

ABA CEO Simon Birmingham said banks were on high alert for scams as criminals look to cash in on this week's Census.

"The Census is a significant event impacting millions of Australians and criminals will be looking to get a pay day out of it," Mr Birmingham said.

"While this is an important information gathering event that everyone should play their part in, please make sure that you aren't passing personal or financial information straight into the hands of criminals.

"Be on alert for scams impersonating the ABS or Australian Bureau of Statistics. If you are contacted about the Census, take a moment to verify the email, phone call or text.

"Any requests for bank details or credit card information, cash or donations, banking passwords, identity documents or your tax file number should be a major red flag. The ABS and Census would never ask for your banking details or solicit a payment.

"If you think you’ve been tricked or entered your banking details on a fake link, don't wait, contact your bank straight away. Your bank can act fast to protect your account and help try to get your money back.

"Stay safe this Census week. If something feels off, it pays to stop, check and protect yourself."
