Is It Legal For Employers To Ask A Candidate’s Age In Job Interviews In Australia?

Interviews are about finding the right person for your team, and asking great questions is part of that. But some topics are regulated by law - and age is one of them.

In Australia, age is a protected attribute. That means how you ask about it (and what you do with the information) matters. While it isn’t always unlawful to ask a candidate’s age, it can be unlawful to request or use that information in a way that leads to discrimination - and there are far better ways to check what you actually need.

In this guide, we’ll explain when age-related questions can be risky, when they may be permitted, the legal risks for employers, and practical steps to design a fair, defensible hiring process that still gets you the information you need.

What Do Australian Laws Say About Asking Age?

Age is a protected attribute under Australian anti-discrimination laws. The key law at the federal level is the Age Discrimination Act 2004 (Cth). It prohibits discrimination based on age across all stages of employment - including advertising, interviews, shortlisting and offers.

Every state and territory also has its own anti-discrimination legislation with similar protections. Together, these laws make it unlawful to treat a person less favourably because of their age or to impose requirements that disadvantage people of a certain age without a valid, reasonable basis.

The Fair Work Act 2009 (Cth) also prohibits adverse action because of a protected attribute like age. Importantly, this protection extends to prospective employees, not just current staff. This means a candidate could allege adverse action if they were refused employment because of age.

So, is it illegal to ask for a candidate’s age? Not automatically. The law focuses on discrimination - what you ask, why you ask it, how you use the information, and whether there’s a lawful, necessary reason connected to the job. However, asking for age without a genuinely job-related reason is risky and can be used as evidence of discriminatory intent or effect.

If you’re reviewing the scope of interview questions more broadly, it’s wise to check examples of illegal interview questions so your team knows what to avoid.

When Can Asking About Age Be Lawful?

There are limited, specific circumstances where requesting or confirming age may be reasonable and compliant. The guiding principle is necessity: can you achieve the job-related purpose without directly asking a person’s age or date of birth?

Minimum Legal Working Age

Some roles may be restricted to people above a certain age (for example, serving alcohol, working late at night, or hazardous tasks for minors). In these cases, it’s usually better to ask a neutral question such as “Are you legally able to perform all duties of this role (including serving alcohol)?” rather than “How old are you?”

Licensing, Insurance Or Legal Compliance

Certain duties may require a licence or accreditation that is, in practice, only available above a set age (for example, driving company vehicles under a particular insurance policy). Again, frame your question around the requirement: “Do you hold a valid driver’s licence and meet the insurer’s eligibility criteria for this vehicle?”

Inherent Requirements Of The Role

In rare cases, age can relate to the inherent requirements of a role (for example, casting an actor portraying a specific age group). These scenarios are narrowly interpreted. You should be confident there is a genuine occupational requirement and document your reasoning.

Even when an exception applies, apply a “least intrusive” approach: ask for confirmation that the candidate meets a legal or licensing requirement, rather than their exact age or date of birth.

What Counts As Age Discrimination During Recruitment?

Discrimination can be direct or indirect. In interviews and screening, risky conduct includes:

• Asking “How old are you?”, “What year were you born?”, or requesting a date of birth without a lawful need.
• Comments implying someone is “too old” or “too young” for the role, or assumptions about technology skills, stamina or “culture fit” linked to age.
• Job ads that specify age ranges (e.g. “under 30s only”) unless a genuine legal exception applies.
• Selection criteria that disadvantage a particular age group without being necessary (for example, requiring a specific number of “recent” years’ experience when broader experience would do).

Intent isn’t required. Even if you didn’t mean to discriminate, the question or criterion can still amount to unlawful discrimination if it disadvantages someone because of age and is not reasonable in the circumstances.

A good rule of thumb: focus every question on whether the candidate can perform the inherent requirements of the position, with or without reasonable adjustments, and avoid asking for personal attributes unless the law genuinely requires it.

What Are The Risks For Employers Who Ask About Age?

Asking about age without a sound, job-related reason can create several issues:

• Discrimination complaints: Candidates can make a complaint to the Australian Human Rights Commission or a state/territory commission.
• General protections claims: Prospective employees are protected from adverse action for reasons including age under the Fair Work Act. While job applicants can’t bring unfair dismissal claims, they may pursue general protections if they believe age affected the hiring decision.
• Reputational damage: Ageist interview practices can harm your employer brand and reduce your talent pool.
• Privacy non-compliance: Collecting dates of birth or other sensitive personal information engages privacy obligations, including data minimisation and secure handling. If you collect personal data during recruitment, a clear Privacy Policy and appropriate collection notices are important.

If a complaint arises, having a documented, fair process and role-related criteria makes it easier to show that decisions were based on merit, not protected attributes. If you need guidance responding to a complaint, our team assists employers with discrimination claims and practical next steps.

How Do You Handle Age-Related Requirements Without Discriminating?

You can stay compliant and still gather what you need. The key is to design your process around the role’s requirements, not the person’s attributes.

1) Write Job Ads That Set Out Any Legal Requirements

If the law imposes a minimum age or licence, state it neutrally: “This role involves serving alcohol; applicants must be legally permitted to do so.” Avoid asking for a date of birth or using age descriptors (e.g. “young and energetic”).

2) Use Neutral, Role-Focused Questions

Replace “How old are you?” with questions like:

• “Are you legally able to perform all duties of this role?”
• “Do you hold the required accreditation/licence for ?”
• “Are you available to work the required shifts, including late nights/weekends?”

These alternatives check compliance and availability without seeking protected information.

3) Standardise Your Interviews

Use a structured interview guide and scoring matrix so every candidate is asked the same role-related questions. This reduces the risk of off‑the‑cuff questions veering into protected territory and helps you justify decisions later.

If you’re refreshing your interview content, it helps to brief your team on common red flags using a shortlist of illegal interview questions and compliant alternatives.

4) Train Anyone Involved In Hiring

Provide short, practical training on protected attributes and lawful questioning, and ensure those running interviews understand the job’s inherent requirements. Keep a copy of your recruitment policy and interview guide handy.

5) Keep Clear Records

Document your selection criteria, interview notes, and the reasons for your final decision. Good records are invaluable if a complaint is made later, and they reinforce a merit-based process.

6) Minimise Personal Data Collection

Only collect what you truly need, store it securely and delete it when it’s no longer required. If your recruitment process collects personal information, provide a Privacy Collection Notice and make your Privacy Policy easy to find. This aligns with Australian privacy principles and gives candidates confidence in your process.

7) Have Clear Policies In Place

Set expectations with a written recruitment and equal opportunity policy. Policies can sit within a broader Workplace Policy framework and help managers stay aligned during hiring.

What Interview Questions Should You Avoid (And What To Ask Instead)?

To reduce risk, don’t ask questions that directly or indirectly reveal age unless there’s a legal need. Avoid:

• “How old are you?” or “What’s your date of birth?”
• “What year did you graduate from high school?”
• “How long do you plan to work before retiring?”
• “We’re a young team - would you fit in?”

Swap them for role-linked wording, such as:

• “Are you able to perform all inherent requirements of the role, with or without reasonable adjustments?”
• “This role requires weekend and late-night shifts - can you work those hours?”
• “The position includes driving a company vehicle under our insurance policy - are you eligible under that policy?”

Keeping questions firmly tied to skills, licensing, availability and workplace safety gives you the information you need without collecting protected attributes unnecessarily.

What Documents And Policies Should Employers Put In Place?

Even small teams benefit from a basic hiring toolkit that promotes consistency and compliance. Consider the following:

• Recruitment And Equal Opportunity Policy: Sets out your commitment to merit-based selection and lawful questioning. This can form part of your broader Workplace Policy suite.
• Structured Interview Guide And Scorecard: Standardises questions and helps keep interviews focused on inherent requirements.
• Privacy Collection Notice: Explains why you’re collecting candidate information, how you use it and for how long, alongside your Privacy Collection Notice.
• Privacy Policy: Sets out how your business handles personal information during recruitment and onboarding. A clear, up‑to‑date Privacy Policy builds trust and supports compliance.
• Employment Contract: Once you’ve selected a candidate, issue a tailored Employment Contract that covers role duties, pay, hours, probation, policies and confidentiality.
• Complaint Handling Process: Outline how discrimination concerns are raised and managed internally. This can sit within your policy framework and be supported by training.

You may not need every document from day one, but putting core policies and templates in place early makes hiring smoother and reduces legal risk as you grow.

What If A Candidate Volunteers Their Age?

It happens. A candidate might mention their age or put their date of birth on a CV. You don’t need to stop the interview, but do steer the conversation back to the role.

• Don’t make decisions based on age unless a narrow legal exception genuinely applies and is documented.
• Continue assessing against the selection criteria and inherent requirements of the position.
• Keep your notes focused on merit (skills, qualifications, examples of past performance) rather than personal attributes.

If sensitive or unnecessary personal information is provided, ensure it’s handled consistently with your privacy obligations and only retained as long as needed for the recruitment process.

Key Takeaways

• Asking a candidate’s age isn’t automatically unlawful, but using age (or asking about it) without a genuine, job‑related reason can amount to unlawful discrimination.
• Rely on neutral, role‑focused questions that test legal eligibility, licensing, shifts and inherent requirements, rather than personal attributes.
• General protections under the Fair Work Act apply to prospective employees; while applicants can’t bring unfair dismissal claims, age‑based adverse action is prohibited.
• Set up a consistent process: structured interviews, short training for hiring managers, clear records and a written policy reduce risk and improve hiring quality.
• If your process collects personal information, support it with a Privacy Collection Notice and a current Privacy Policy.
• When you’re ready to hire, lock in an Employment Contract and ensure your Workplace Policy framework covers recruitment and equal opportunity.
