Australia's 66-question census held Tuesday, Aug. 11, now includes optional questions about sexual orientation and gender identity—marking the first time the nation's five-yearly survey has broached these topics under a center-left Labor government that promised them during its 2022 campaign.
The questions are voluntary for household members 16 and older. Sexual orientation options include straight, gay or lesbian, bisexual, don't know, prefer not to answer, or a respondent's own written term. For gender identity, respondents can select man, woman, nonbinary, prefer not to answer, or write in another term. Both join religion as optional census questions.
The government's path to inclusion wasn't straightforward. In August 2024—just two years ago—Deputy Prime Minister Richard Marles had stated the government would maintain the 2021 census format, saying, "We do not want to open up divisive debates in the community now." Two days later, Prime Minister Anthony Albanese reversed course in a radio interview, confirming sexual orientation would be included in the next census.
The Data Collection Push
ABS Chief Statistician David Gruen told Australian Broadcasting Corp that his bureau discovered "a substantial level of interest in asking questions on gender and sexual orientation" during public consultations. "For a proportion of the population … collecting this information is very important. But for other people, it's information that they simply don't want to share," Gruen explained, underscoring the rationale for making both questions optional rather than mandatory.
The voluntary approach reflects a pragmatic governance choice: gather data where citizens willingly provide it, rather than impose uniform requirements that risk lower compliance or community friction. This stands in contrast to some international approaches. Britain asked similar questions in 2021, New Zealand in 2023, and Canada three months ago. Australian National University demographer Liz Allen noted Australia had lagged behind these like-minded countries on the issue.
Compliance and Implementation
Australia's census process carries teeth. Failing to comply with a direction to complete the census can result in a fine of up to 364 Australian dollars ($257) per day. Yet the government allows flexibility in submission timing—people could send forms as soon as they received instructions if they knew their whereabouts on census night.
The ABS expects 85% of responses will be made online, up from almost 80% in 2021, when almost half the population was in pandemic lockdown. Paper forms remain available on request, and field staff assist homeless people and those in remote areas. By Tuesday morning, more than 5 million forms had already been submitted, with almost 11 million forms expected to be completed overall.
The government determines census topics while the Australian Bureau of Statistics decides question wording—a division of responsibility that leaves room for debate over what data serves public interest versus what invites social division.
Why This Matters:
From a governance perspective, this census expansion reveals competing priorities: gathering demographic data that advocacy groups deem essential versus maintaining social cohesion in a divided electorate. The government's initial hesitation in 2024—followed by reversal—signals the political sensitivity surrounding gender and sexuality questions. The voluntary nature of both questions acknowledges a reality that mandatory collection might face resistance or lower response rates. Australia's approach differs from countries like Britain and New Zealand, which integrated similar questions into their censuses years earlier. The data collected will inform policy decisions across health, housing, and anti-discrimination frameworks for years to come, making the quality and comprehensiveness of responses consequential. Whether optional questions yield statistically meaningful results—and whether the data's utility justifies the administrative cost—remains an open question for future analysis.
