Understanding The Sex Discrimination Act: What Australian Businesses Need To Know

Running a business in Australia isn’t just about great products and happy customers - it’s also about building a safe, respectful and legally compliant workplace.

One of the key laws that shapes how you hire, manage and support your team is the Sex Discrimination Act. If you’re an employer (big or small), this isn’t just a box to tick. It’s central to your culture, your reputation and your long-term success.

In this guide, we break down what the Sex Discrimination Act requires, the recent “positive duty” changes, what conduct is unlawful, and the practical steps you can take to comply and manage risk with confidence.

What Is The Sex Discrimination Act?

The Sex Discrimination Act 1984 (Cth) is a national law that protects people from discrimination and harassment on the grounds of sex, sexual orientation, gender identity, intersex status, marital or relationship status, pregnancy, and breastfeeding.

It applies to almost all Australian workplaces and industries - from cafés and trades to startups and national enterprises - and covers the whole employment lifecycle: recruitment, conditions, training, promotion, termination and references.

At its core, the Act aims to ensure equal opportunity and a workplace free from sex-based discrimination, harassment and hostility. It sits alongside other laws you’ll know well (such as the Fair Work Act and work health and safety duties) and complements state and territory anti‑discrimination laws.

If you’re unsure where your business stands, a quick legal health check can help you pinpoint gaps and set priorities.

What Conduct Is Unlawful Under The Act?

The Act prohibits several types of conduct. Understanding each category will help you identify risks early and respond appropriately.

Direct Discrimination

Direct discrimination is less favourable treatment because of a protected attribute. Examples include refusing to hire a pregnant applicant, overlooking a qualified employee for promotion because they’re planning to have a child, or paying someone less because of their sex.

Indirect Discrimination

Indirect discrimination occurs when a requirement, condition or practice is the same for everyone but unfairly disadvantages people with a protected attribute - and it’s not reasonable in the circumstances.

For example, a blanket requirement to work late at short notice could disadvantage workers with caring responsibilities. If the requirement isn’t reasonable (and alternatives exist), it may be unlawful.

Sexual Harassment

Sexual harassment is any unwelcome conduct of a sexual nature in circumstances where a reasonable person would anticipate the conduct might offend, humiliate or intimidate. This includes unwanted touching, sexual comments or jokes, requests for sexual favours, intrusive questions about private life, and sharing sexual content in work channels.

Sex-Based Harassment

Separate from sexual harassment, sex-based harassment is unwelcome conduct on the ground of a person’s sex that is demeaning, humiliating or offensive - for example, insulting remarks about women’s abilities, or hostile generalisations about men or women in a team meeting.

Hostile Work Environment On The Ground Of Sex

It’s also unlawful to subject someone to a workplace environment that is hostile on the ground of sex. This can include repeated sexualised banter, pornographic materials displayed at work, or online channels where sexual content is shared in ways that make the environment intimidating or offensive.

Victimisation

Victimisation is treating someone unfavourably because they’ve made a complaint, proposed to make a complaint, or participated in a process under the Act. Protecting workers from victimisation is essential to the integrity of your complaint process.

Note: The Act also protects pregnancy, potential pregnancy and breastfeeding, and (in certain contexts) family responsibilities. Discrimination can occur in hiring, terms and conditions, promotions, training, termination and more.

The Positive Duty: What’s Required Now?

Since 2022, the Act imposes a “positive duty” on employers and PCBUs (persons conducting a business or undertaking) to take reasonable and proportionate measures to eliminate, as far as possible:

• Sexual harassment
• Sex-based harassment
• Hostile work environments on the ground of sex
• Related acts of victimisation

This is proactive. It’s not enough to react after something goes wrong - you’re expected to take steps to prevent harm in the first place.

The Australian Human Rights Commission (AHRC) now has powers to inquire into and assess compliance with the positive duty. Where the Commission identifies non-compliance, it can work with businesses through education and guidance, or use enforcement tools like compliance notices or enforceable undertakings. If needed, the AHRC can apply to the courts to enforce those notices or undertakings.

In practice, this means your policies, training, leadership, reporting channels and risk controls should work together to prevent and address unlawful conduct - not just sit on a shelf.

How Do You Comply And Manage Risk?

Good compliance is good business - it builds trust, reduces disputes and supports performance. Here’s a practical framework to get you there.

1) Set Clear Standards With Policies

Publish clear, accessible workplace policies that explain expected behaviours, unacceptable conduct and how to raise concerns. At a minimum, cover anti‑discrimination, sexual harassment, bullying, complaint handling, and protection from victimisation. Many businesses bring these together in a Staff Handbook, often supported by specific policies (for example, a standalone anti‑harassment policy and a procedure for complaints). If you’re starting from scratch, it’s worth planning your workplace policies so they’re practical and easy to follow.

2) Train Everyone - Especially Leaders

Provide regular, role-specific training. Frontline staff should understand what conduct is unlawful and how to report concerns. Managers need extra training on receiving complaints, confidentiality, impartial investigations and preventing victimisation. Keep accurate training records.

3) Build Safe, Trusted Reporting Channels

Offer multiple ways to speak up (e.g. line manager, HR, an external reporting email or service). Confirm what will happen at each step, keep matters confidential where possible, and take interim measures to keep people safe while you assess a complaint.

4) Review Recruitment And Advancement Processes

Ensure position descriptions, job ads and interviews focus on genuine requirements. Avoid questions about family plans or other protected attributes, and check selection criteria don’t create unnecessary barriers. It helps to audit your hiring and promotion decisions regularly to spot patterns. If you’re updating your interview packs, steer clear of illegal interview questions and stick to capability-based assessments.

5) Address Risks In Your Day-To-Day Operations

Map out where risks arise (e.g. late-night shifts, travel, conferences, social events, remote worksites, small teams without formal HR). Then introduce controls, such as clear codes of conduct for events, buddy systems, manager check-ins, and rules for workplace chats and collaboration tools.

6) Investigate And Resolve Early

Respond promptly and proportionately. For low-level issues, early intervention and coaching can be effective. For formal complaints, follow a fair process, document your steps and reach findings based on evidence. Apply outcomes consistently and protect people from victimisation.

7) Keep Improving

Set metrics (e.g. training completion, time-to-resolution, anonymous survey results) and review outcomes. Learn from incidents and near-misses. As your business grows or changes, refresh your policies, training and controls so they remain effective.

Vicarious Liability: Why “Reasonable Steps” Matter

Employers can be held vicariously liable for unlawful acts by employees or agents in connection with their employment unless you can show you took all reasonable steps to prevent the conduct.

What counts as “reasonable steps” depends on your size and risks, but typically includes up-to-date policies, regular training, accessible reporting channels, prompt investigations, and action that’s consistent and well documented. The positive duty aligns closely with this risk management approach.

Helpful Documents And Admin To Support Compliance

• Employment Contract: Set expectations (conduct, confidentiality, lawful directions) and link to policies. If you’re hiring, use a current Employment Contract tailored to the role (casual, part-time, full-time or executive).
• Staff Handbook: Centralise policies and processes in one accessible resource. Many businesses adopt a packaged approach like a Staff Handbook to keep onboarding simple.
• Privacy Policy & Collection Notices: If you collect personal information from staff or candidates, ensure your Privacy Policy and collection notices explain how data is handled during recruitment and investigations.
• Whistleblower Policy (if applicable): Larger companies and certain regulated sectors benefit from a structured, confidential reporting policy such as a Whistleblower Policy.

If you’re unsure which documents you need right now versus later, a short consult can map your risks to a sensible document roadmap so you’re not over- or under-engineered.

What Happens If Someone Makes A Complaint?

There are internal and external pathways, and it’s important to handle both with care.

Internal Complaints

Most matters are raised internally first. Act promptly, follow your policy, ensure procedural fairness and document your steps. Interim measures (for example, temporary reporting changes or separation at work) can help keep everyone safe during an investigation.

Australian Human Rights Commission (AHRC)

An affected person may lodge a complaint with the AHRC. The Commission can inquire into the matter and often facilitates conciliation. If a complaint isn’t resolved and is terminated by the Commission, the complainant can choose to commence court proceedings (usually in the Federal Court or Federal Circuit and Family Court).

Courts can make a range of orders, including compensation, declarations, injunctions and other remedies appropriate to the circumstances. The Sex Discrimination Act is a civil law framework - criminal liability for conduct like assault or stalking would arise under separate criminal laws.

Positive Duty Compliance

Separately, the AHRC can inquire into your compliance with the positive duty (even without a specific complaint). If it identifies non-compliance, it may provide guidance, or use tools such as compliance notices and enforceable undertakings. The Commission can also apply to a court to enforce those tools if necessary.

The best protection is to be proactive: align leadership, policies, training and reporting, and show that you review and improve regularly. That approach reduces the chance of incidents and also demonstrates you’re taking “reasonable and proportionate” measures if your efforts are scrutinised.
