Discrimination law in Australia: an employer's guide
Reviewed by Mellow Editorial Team, HR & payroll content team
Discrimination law in Australia prohibits employers from treating employees or job applicants unfairly on the basis of protected attributes — covering hiring, pay, promotion, dismissal and workplace conditions. Navigating it well means understanding which laws apply, what they require, and how to build practices that reduce your risk.
The legal framework: federal and state laws working together
Australia does not have a single discrimination statute. Instead, a set of federal laws covers specific protected attributes, and each state and territory adds its own legislation on top.
The main federal Acts are:
- Age Discrimination Act 2004
- Disability Discrimination Act 1992
- Racial Discrimination Act 1975
- Sex Discrimination Act 1984 (which also covers sexual orientation, gender identity, intersex status, pregnancy and breastfeeding)
The Australian Human Rights Commission (AHRC) administers these Acts and handles complaints at the federal level.
State and territory laws — such as the Equal Opportunity Act in Victoria and New South Wales, and equivalents in other jurisdictions — often cover additional attributes, including criminal record, physical features or political opinion, and may have different complaint processes and remedies. If your business operates across multiple states, both federal and relevant state laws apply simultaneously.
This is general information, not legal advice. For advice specific to your circumstances, consult an employment lawyer or contact the AHRC or your relevant state body.
Direct and indirect discrimination: what the distinction means in practice
Discrimination can be direct or indirect, and employers need to understand both.
Direct discrimination is treating someone less favourably because of a protected attribute. Declining to interview a candidate because she is pregnant is a straightforward example.
Indirect discrimination is more subtle. It occurs when a workplace rule, policy or practice appears neutral but has a disproportionate negative effect on people with a particular attribute — and cannot be reasonably justified. A minimum height requirement for a role that does not genuinely need it could indirectly discriminate on the basis of sex or national origin.
The "reasonably justified" or "inherent requirements" defence matters here. You can require that an employee be able to perform the genuine, core requirements of a role. What you cannot do is apply a blanket exclusion where a reasonable adjustment would allow the person to meet those requirements.
Positive duty and the shift toward prevention
A significant development in Australian discrimination law is the move toward positive duty — an obligation on employers to take proactive steps to prevent discrimination and harassment, rather than simply respond when a complaint arises.
Under amendments to the Sex Discrimination Act that came into effect in 2022 and became fully enforceable from 2023, employers are required to take reasonable and proportionate measures to eliminate sexual harassment, sex-based harassment and certain other conduct in the workplace. The AHRC has the power to investigate and take enforcement action against employers who do not comply, without needing a complaint from an individual.
This is a genuine shift from the older complaint-driven model. In practical terms it means reviewing policies, training managers, assessing workplace risks and documenting what you have done — not waiting for something to go wrong.
Reasonable adjustments and the disability context
The Disability Discrimination Act requires employers to make reasonable adjustments for employees and job applicants with a disability, unless doing so would cause unjustifiable hardship. There is no fixed definition of unjustifiable hardship — it is assessed by weighing factors such as cost, the size and resources of the business, and the practicability of the adjustment.
Common adjustments include flexible hours, modified workstations, changes to duties or access to assistive technology. Refusing to consider any adjustment, or making assumptions about what a person with a disability can or cannot do, is where many employers create liability.
The same principle extends to other attributes. Pregnancy, for instance, may require temporary changes to duties or hours to address safety concerns. The test is whether an adjustment is reasonable given the particular circumstances.
Building compliant workplace practices
Discrimination law compliance is largely about having the right processes and acting on them consistently. Some practical areas to focus on:
Recruitment: Advertise and assess on skills, experience and genuine job requirements. Avoid questions about age, family plans, health or any other protected attribute unless directly relevant to an inherent job requirement and legally permissible.
Policies: A standalone equal opportunity or anti-discrimination policy, combined with a clearly communicated complaints procedure, sets expectations and gives you a process to follow if something is raised.
Training: Managers carry significant risk because their decisions directly affect employees. Regular, practical training — not a tick-box exercise — on discrimination, harassment and how to handle complaints reduces both the chance of incidents and the liability exposure if one occurs.
Documentation: Record the reasons for significant employment decisions such as hiring, promotions, performance management and dismissal. If a decision is ever challenged, contemporaneous records are far more credible than reconstructed ones.
Complaints handling: Take internal complaints seriously and investigate them promptly and fairly. A complaint handled poorly — ignored, dismissed or mishandled — can escalate into a formal external complaint or litigation that could have been avoided.
