Discrimination claims represent one of the highest-risk areas of Australian employment law, carrying reputational, financial, and cultural consequences for organisations that get it wrong. With the introduction of the positive duty under the Sex Discrimination Act 1984 and continued regulatory focus from the Australian Human Rights Commission (AHRC), employers can no longer treat compliance as a reactive exercise. This guide sets out what discrimination means under Australian law, the legal frameworks employers must navigate, and practical steps to reduce risk.
What is Workplace Discrimination Under Australian Law?
Workplace discrimination occurs when an employee or prospective employee is treated unfavourably because of a personal characteristic protected by law, rather than because of their skills, conduct, or performance. It can arise at any stage of the employment relationship, from recruitment and promotion decisions through to termination.
Direct vs Indirect Discrimination
Direct discrimination occurs when a person is treated less favourably than another person would be treated in similar circumstances, because of a protected attribute. An obvious example is refusing to hire a candidate because of their age or declining to promote an employee because they are pregnant.
Indirect discrimination is less obvious but equally unlawful. It occurs when a workplace requirement, condition, or practice appears neutral on its face but disproportionately disadvantages people with a particular attribute, and is not reasonable in the circumstances. A requirement that all staff work full-time hours, for example, may indirectly disadvantage employees with caring responsibilities, disproportionately affecting women, unless the requirement can be justified as reasonable.
Which Laws Govern Workplace Discrimination?
Discrimination in the Australian workplace is regulated by an overlapping framework of federal and state legislation.
The Fair Work Act General Protections
Part 3-1 of the Fair Work Act 2009 (Cth) prohibits an employer from taking “adverse action” against an employee or prospective employee because of a protected attribute, or because they have exercised a workplace right. Adverse action includes dismissal, demotion, altering an employee’s position to their detriment, or discriminating between employees. These general protections operate independently of, and in addition to, anti-discrimination legislation.
Federal Anti-Discrimination Acts and the AHRC
At the federal level, discrimination is separately governed by the Sex Discrimination Act 1984, Racial Discrimination Act 1975, Disability Discrimination Act 1992, and Age Discrimination Act 2004. Complaints under these Acts are handled by the AHRC, which can investigate, conciliate, and, if unresolved, refer matters to the Federal Court or Federal Circuit and Family Court.
State and Territory Discrimination Laws
Each state and territory also has its own anti-discrimination legislation, such as the Anti-Discrimination Act 1977 (NSW) and the Equal Opportunity Act 2010 (Vic), enforced by bodies like Anti-Discrimination NSW and the Victorian Equal Opportunity and Human Rights Commission. These often cover additional protected attributes and provide an alternative complaint pathway to the federal system.
What are the Protected Attributes?
While specific attributes vary slightly between jurisdictions, commonly protected characteristics across Australian discrimination law include age, sex, pregnancy, marital or relationship status, family or caring responsibilities, race, colour, national or ethnic origin, disability, religion, sexual orientation, gender identity, intersex status, and industrial activity (such as union membership). Employers should check the specific list of attributes covered in their relevant state or territory legislation, as coverage is not uniform nationally.
What is the Employer’s Positive Duty?
Since December 2022, amendments introduced through the Respect@Work reforms have imposed a positive duty on employers under the Sex Discrimination Act. This requires employers to take proactive and meaningful action to eliminate, as far as possible, sex discrimination, sexual harassment, and victimisation in the workplace, rather than simply responding after an incident occurs.
Since December 2023, the AHRC has held enforcement powers to assess compliance with the positive duty, including the ability to conduct inquiries, issue compliance notices, and enter into enforceable undertakings. The AHRC’s guidelines set out seven standards employers are expected to meet, covering leadership, culture, knowledge, risk management, support, reporting, and monitoring.
What Does “Reasonable and Proportionate” Mean?
Much of Australian discrimination law turns on whether an employer’s actions, or a workplace practice, were reasonable and proportionate in the circumstances. This standard appears in the positive duty guidelines, in assessing indirect discrimination, and in the duty to make reasonable adjustments for employees with disability.
Relevant factors typically include the nature and size of the business, the cost and practicality of alternative approaches, the severity of the risk being addressed, and the impact on the affected employee if no action is taken. What is reasonable for a large national employer with dedicated HR resources may differ from what is reasonable for a small business, but the obligation to consider reasonable steps applies regardless of size.
What is the Employer Risk in a Discrimination Claim?
The Reverse Onus of Proof in Adverse Action
Under section 361 of the Fair Work Act, general protections claims carry a reverse onus of proof. Once an employee establishes that adverse action occurred, it is presumed that the action was taken for the alleged unlawful reason, unless the employer proves otherwise. This places a significant evidentiary burden on employers, making clear documentation of legitimate, non-discriminatory reasons for employment decisions essential.
Vicarious Liability for Employee Conduct
Employers can be held vicariously liable for discriminatory conduct or harassment carried out by their employees or agents in connection with their employment, even where the employer was unaware of the conduct. However, most discrimination Acts provide a defence where the employer can demonstrate it took all reasonable steps to prevent the conduct from occurring, reinforcing the importance of proactive policies, training, and reporting mechanisms rather than a reactive approach.
When is Different Treatment Lawful?
Not all differential treatment amounts to unlawful discrimination. Recognised exceptions typically include genuine occupational requirements (for example, requiring a specific gender for a role involving personal care in limited, legislatively defined circumstances), inherent requirements of a role that cannot be met even with reasonable adjustments, special measures designed to achieve substantive equality for a disadvantaged group, and actions required to comply with work health and safety obligations. These exceptions are narrowly interpreted by courts and tribunals, and employers should seek advice before relying on them.
How Can Employers Comply and Reduce Discrimination Risk?
Practical compliance measures include maintaining clear, up-to-date discrimination and equal opportunity policies; delivering regular training to managers and staff, with a particular focus on those involved in recruitment and performance decisions; documenting the genuine business reasons behind employment decisions at the time they are made; establishing accessible and confidential reporting channels; conducting regular risk assessments in line with the positive duty standards; and ensuring investigations into complaints are prompt, procedurally fair, and independent.
Common Mistakes That Increase Discrimination Risk
Many discrimination claims arise not from deliberate wrongdoing, but from poor process. Common pitfalls include relying on informal or emotional reasons for adverse decisions, applying blanket policies without considering individual circumstances, failing to update policies to reflect the positive duty, treating discrimination and harassment training as a one-off compliance exercise rather than an ongoing commitment, and dismissing employee concerns without proper investigation.
When You Need Outside Help, Call HR Expertise
Discrimination law is complex, fast-evolving, and highly fact-dependent. Where a complaint has been raised, a workplace investigation is required, or a policy review is overdue, engaging experienced HR or workplace relations specialists can help organisations respond appropriately, protect against legal exposure, and rebuild trust within the team.
Frequently Asked Questions
Can an employee bring a discrimination claim without being dismissed?
Yes. Discrimination claims are not limited to dismissal. An employee can bring a claim in relation to recruitment decisions, denial of a promotion, changes to duties or hours, refusal of flexible work requests, harassment, or any other unfavourable treatment linked to a protected attribute, regardless of whether their employment has ended.
Does it matter if discrimination wasn’t intentional?
Generally, no. Most Australian discrimination law focuses on the effect of the conduct rather than the intent behind it. An employer can be found liable for discrimination even where there was no deliberate intention to disadvantage the employee, particularly in cases of indirect discrimination.
How long do employees have to lodge a discrimination complaint?
Timeframes vary by jurisdiction and pathway. Federal general protections dismissal claims under the Fair Work Act generally must be lodged within 21 days of dismissal, while AHRC complaints and state-based discrimination complaints typically allow longer periods, though timely lodgement is always advisable. Claims not involving dismissals carry a statute of limitations of 6 years. Employees should confirm exact timeframes with the relevant body, as they can change.
Is a workplace policy enough to protect against a discrimination claim?
No. A written policy alone is unlikely to satisfy the positive duty or provide a full defence to vicarious liability. Employers must also demonstrate active implementation, including training, monitoring, and genuine enforcement, to show that reasonable steps were taken to prevent discrimination from occurring.
