Equality and inclusion duties in Australia
Reviewed by Mellow Editorial Team, HR & payroll content team
Employers in Australia have concrete legal obligations around equality and inclusion — not aspirational targets, but enforceable duties under federal and state law. Getting them wrong exposes a business to complaints, investigations and compensation orders.
The core federal framework
Four federal Acts form the backbone of Australia's anti-discrimination and equality obligations:
- Sex Discrimination Act 1984 — prohibits discrimination on the basis of sex, gender identity, intersex status, sexual orientation, marital or relationship status, pregnancy, and breastfeeding. It also covers sexual harassment.
- Racial Discrimination Act 1975 — prohibits discrimination on the basis of race, colour, national or ethnic origin, and descent.
- Disability Discrimination Act 1992 — requires employers to make reasonable adjustments for employees and applicants with a disability, unless doing so would cause unjustifiable hardship.
- Age Discrimination Act 2004 — prohibits discrimination on the basis of age in both directions — against older and younger workers.
The Australian Human Rights Commission (AHRC) handles complaints under all four Acts. A complaint can be lodged by any employee, contractor or job applicant who believes they have been treated unlawfully.
Positive duty: the shift from complaint-driven to proactive
The most significant recent development is the positive duty introduced into the Sex Discrimination Act. Since December 2023, employers have had a proactive, legally enforceable obligation to take reasonable and proportionate measures to eliminate:
- sexual harassment and sex-based harassment in the workplace
- sex discrimination
- conduct creating a hostile workplace environment on the basis of sex
- victimisation related to any of the above
This is a structural change. Previously, the law was largely complaint-driven — someone had to be harmed before action was required. The positive duty flips that: employers must act before harm occurs. The AHRC has the power to investigate compliance even without an individual complaint, and to issue compliance notices.
"Reasonable and proportionate" is assessed against the size and resources of the business. A sole trader has lighter obligations than a company with 500 staff, but no employer is exempt.
Reasonable adjustments for disability
Under the Disability Discrimination Act, if an employee or applicant has a disability, an employer must consider whether reasonable adjustments would allow them to perform the inherent requirements of the role. The obligation applies at every stage: recruitment, day-to-day work, return-to-work after illness or injury, and redeployment.
Adjustments might include modified hours, adaptive technology, a change in workspace layout, or altered duties. The employer is not required to create an entirely new role or bear costs that cause unjustifiable hardship — but "unjustifiable hardship" is a high bar. Cost alone is rarely sufficient justification; courts and tribunals look at the overall circumstances of the business.
Failing to consider adjustments — not just refusing them — can itself constitute discrimination.
State and territory laws add another layer
Each state and territory has its own anti-discrimination legislation that often covers additional protected attributes or imposes different procedural requirements. For example:
- In Victoria, the Equal Opportunity Act 2010 includes a positive duty to eliminate discrimination and sexual harassment, covering a broader range of attributes than the federal Acts alone.
- In Queensland, the Anti-Discrimination Act 1991 covers attributes such as trade union activity and lawful sexual activity.
- New South Wales, South Australia, Western Australia and others each have parallel schemes.
Where an employee is covered by both federal and state law, they can generally choose which avenue to pursue. Employers operating across multiple states need to be across all applicable frameworks.
Practical obligations in day-to-day employment
These laws affect decisions employers make routinely:
Recruitment. Job advertisements, interview questions and selection criteria must not directly or indirectly discriminate on any protected attribute. Asking a candidate about their plans to have children, for example, is a direct exposure under the Sex Discrimination Act.
Pay and conditions. Paying employees differently because of a protected attribute — including sex — is unlawful. Pay equity audits are increasingly expected, particularly in larger organisations.
Performance and termination. A performance management process that applies more harshly to employees of a particular attribute, or a dismissal that is actually motivated by a protected characteristic, can give rise to both discrimination complaints and unfair dismissal claims running in parallel.
Policies and training. Under the positive duty, having documented policies and delivering regular training on sexual harassment and discrimination is no longer just good practice — it is part of what the AHRC expects when assessing whether an employer has taken reasonable steps. A policy sitting in a drawer that nobody has read does not discharge the duty.
Complaints handling. Employers need a clear internal process for receiving and investigating complaints. How a complaint is handled after it is made is scrutinised closely; victimising someone who raises a concern is separately unlawful.
