Anti-Discrimination Obligations in the Australian Workplace: What Employers Must Know

Australia has some of the most comprehensive workplace discrimination protections in the world. As an employer, you are required not just to avoid discrimination — you have a positive duty to take reasonable and proportionate measures to eliminate unlawful discrimination from your workplace. Failing to understand and meet these obligations exposes your business to legal claims, significant financial liability, and reputational damage.

The Legal Framework

Anti-discrimination obligations for Australian employers come from multiple overlapping sources:

Federal Legislation

• Age Discrimination Act 2004 — prohibits discrimination based on age
• Australian Human Rights Commission Act 1986 — covers discrimination in employment on the basis of political opinion, religion, social origin, nationality, and sexual orientation
• Disability Discrimination Act 1992 — prohibits discrimination based on disability
• Racial Discrimination Act 1975 — prohibits discrimination based on race, colour, ethnicity, and national origin
• Sex Discrimination Act 1984 — prohibits discrimination based on sex, sexual orientation, gender identity, intersex status, marital/relationship status, pregnancy, breastfeeding, and family responsibilities

The Positive Duty Under the Sex Discrimination Act

Since December 2022, employers have a positive duty under the Sex Discrimination Act to take reasonable and proportionate measures to eliminate, as far as possible:

• Workplace sexual harassment
• Sex discrimination
• Hostile work environments
• Victimisation related to these matters

This is a proactive obligation — you must take steps to prevent these things from occurring, not merely respond when they do.

State and Territory Legislation

Each state and territory has its own anti-discrimination legislation that may cover additional protected attributes or provide different remedies:

• NSW: Anti-Discrimination Act 1977
• Victoria: Equal Opportunity Act 2010
• Queensland: Anti-Discrimination Act 1991
• South Australia: Equal Opportunity Act 1984
• Western Australia: Equal Opportunity Act 1984
• Tasmania: Anti-Discrimination Act 1998
• ACT: Discrimination Act 1991
• NT: Anti-Discrimination Act 1992

In some states, additional protected attributes apply — for example, some states protect against discrimination based on criminal record, spent convictions, or irrelevant medical records.

Fair Work Act Protections

The Fair Work Act 2009 prohibits adverse action against employees based on protected attributes including race, sex, sexual orientation, age, disability, marital status, family responsibilities, pregnancy, religion, political opinion, national extraction, and social origin. Unlike discrimination legislation, these protections are enforced through the Fair Work Commission.

What Is Unlawful Discrimination?

Discrimination is treating someone less favourably, or disadvantaging them, because of a protected attribute. Discrimination can be:

Direct Discrimination

Treating someone less favourably because of a protected attribute. Examples:

• Not hiring someone because of their race
• Paying a female employee less than a male employee in the same role
• Refusing to accommodate a disabled employee's needs
• Dismissing an employee because they are pregnant

Indirect Discrimination

A rule, policy, or requirement that appears neutral but disadvantages people with a protected attribute. Examples:

• A physical fitness requirement that cannot be met by employees with certain disabilities (unless the requirement is genuinely necessary for the role)
• A requirement to work Saturdays that disproportionately disadvantages employees with certain religious beliefs

Harassment

Behaviour that creates a hostile, intimidating, or offensive environment because of a protected attribute. Sexual harassment — unwelcome sexual conduct — is a specific form of harassment that is unlawful under the Sex Discrimination Act.

Victimisation

Taking adverse action against someone because they have made a discrimination complaint, or assisted someone who has.

The Positive Duty: What "Reasonable and Proportionate" Looks Like

The positive duty introduced in 2022 requires employers to actively prevent sexual harassment, sex-based harassment, and hostile work environments. The Australian Human Rights Commission has published guidelines on compliance with the positive duty, which include:

Leadership: Senior leaders must visibly support and model respectful behaviour, and take discrimination and harassment complaints seriously.

Culture: Employers must foster a workplace culture that treats all employees with dignity and respect, and does not tolerate discriminatory or harassing behaviour.

Knowledge: Employees must understand what conduct is prohibited and what to do if they experience or witness it.

Risk management: Employers must proactively identify risks of discrimination and harassment — for example, in high-risk settings like male-dominated industries, late-night work environments, or client-facing roles with overnight travel.

Support: Employees must know how to report concerns and trust that they will be taken seriously.

Reporting and response systems: Employers must have mechanisms for reporting concerns and responding to them effectively.

Employer Liability for Discrimination by Employees

Under both state anti-discrimination legislation and the Sex Discrimination Act, employers can be vicariously liable for discrimination or harassment committed by their employees, unless the employer can demonstrate that it took all reasonable steps to prevent the conduct.

What this means: if one of your employees sexually harasses another, your business can be held liable — unless you had appropriate policies, training, and complaint procedures in place and can demonstrate you took all reasonable preventive steps.

"All reasonable steps" for a small business typically includes:

• A written anti-discrimination and harassment policy
• Training for all employees on the policy and expected standards
• A clear complaints procedure
• Prompt and effective investigation of complaints
• Consequences for those who breach the policy

Practical Steps to Reduce Risk

1. Implement a Clear Policy

Develop (or update) an equal opportunity, anti-discrimination, and anti-harassment policy that:

• Identifies all protected attributes under applicable law
• Defines direct and indirect discrimination and harassment
• Explains the complaint process
• Sets out consequences for breach
• Is reviewed regularly

2. Train All Employees

Provide training to all employees — including managers — on anti-discrimination obligations and expectations. Training should be practical, not just a checkbox exercise.

For managers, training should include how to handle complaints and how to avoid discriminatory decisions in hiring, promotion, and performance management.

3. Review Hiring and Management Practices

Audit your hiring criteria, interview questions, and selection processes to identify any potential indirect discrimination. For example:

• Avoid asking about family plans, childcare arrangements, or relationship status in interviews
• Use structured interviews with consistent questions for all candidates
• Document selection decisions and the reasons for them

4. Respond to Complaints Promptly

If a discrimination or harassment complaint is made, investigate it promptly, impartially, and thoroughly. Do not dismiss complaints, retaliate against complainants, or conduct superficial investigations.

5. Consider Reporting and Support Mechanisms

Make it easy for employees to report concerns — including anonymous reporting options if your business size supports them. Ensure employees know they will not be punished for making a good-faith complaint.

The Cost of Getting It Wrong

Discrimination complaints can result in:

• Compensation for financial loss (lost wages, reduced earning capacity)
• Compensation for injury to feelings, humiliation, and distress
• Orders requiring the employer to change practices
• Public findings that damage reputation

Under the Sex Discrimination Act, the Australian Human Rights Commission can conduct compliance audits and has enforcement powers where it finds systemic non-compliance with the positive duty.
