Who must take reasonable and proportionate measures to prevent sex discrimination?
The applicability test for Take reasonable and proportionate measures to prevent sex discrimination, sexual harassment and victimisation (positive duty) (AHRC and FWC), computed across 35 industries, 9 business structures and 6 size bands.
Short answer: Some businesses
Applies when the business has employees, contractors or labour hire.
What the obligation is
Employers have a proactive duty to prevent workplace sexual harassment — AHRC has enforcement powers from December 2023.
Section 47C of the Sex Discrimination Act 1984 (Cth) requires every employer and every person conducting a business or undertaking to take reasonable and proportionate measures to eliminate, as far as possible, unlawful sex discrimination in employment, sexual harassment, harassment on the ground of sex, hostile workplace environments, and related victimisation. The duty covers conduct by the duty holder itself, its employees or workers and its agents, and also conduct by third parties, such as customers or clients, towards its employees or workers. What is reasonable and proportionate depends on the size, nature and circumstances of the business, its resources, and the practicability and cost of the measures (s 47C(6)). The duty sits alongside, and does not limit, work health and safety duties. Division 4A of the Australian Human Rights Commission Act 1986 lets the Commission inquire into compliance, issue compliance notices and accept enforceable undertakings.
The applicability test
Applies when the business has employees, contractors or labour hire.
How the regulator frames it: Every employer and every PCBU in Australia, whatever its size: sole traders with workers, partnerships, companies, not-for-profits and public sector employers. Size and resources affect what measures are reasonable and proportionate, not whether the duty applies.
What triggers it: Employing anyone, or conducting a business or undertaking in which workers carry out work; the duty extends to conduct by the duty holder's agents and to conduct by any person towards its employees or workers.
Jurisdiction: Commonwealth law, so the test is the same in every state and territory.
Which industries are in or out
Outcome across the 35 industries Rules Mate maps (35 of 35: depends on size or structure).
The answer is the same in every industry: depends on size or structure. Industry does not change who must comply.
Business structure and size
Structure does not change the answer across all industries: for every structure the answer is "depends on size or structure".
| Size band | Answer across all industries, any structure |
|---|---|
| No employees (turnover $100K–$1M) | No |
| 1–5 employees (turnover $100K–$1M) | Yes |
| 6–19 employees (turnover $1M–$3M) | Yes |
| 20–99 employees (turnover $3M–$10M) | Yes |
| 100–499 employees (turnover $10M–$100M) | Yes |
| 500+ employees (turnover $100M–$1B) | Yes |
Worked examples
Each line is one run of the Rules Mate applicability engine for a single business profile, with the reason the engine gives:
- Pty Ltd company in real estate agents with 6–19 employees, turnover $1M–$3M: applies. You have employees (6–19)
- Pty Ltd company in real estate agents with no employees, turnover $100K–$1M: does not apply. Requires employees, contractors or labour hire.
What you must do, and when
- When due
- Ongoing. If the Commission issues a compliance notice, it specifies a reasonable period (at least 21 days) to take the required action; reconsideration or court review must be sought within 21 days.
- Frequency
- Ongoing
- Evidence to keep
- Risk assessment of sex discrimination, sexual harassment and hostile environment risks, including from third parties; prevention plan and policies; leadership accountability and reporting; training records; reporting and complaints procedures with records of responses; monitoring and review of the effectiveness of measures.
- Status
- Current
- Priority
- Critical
Penalty for not complying
Maximum penalty: No direct civil penalty attaches to section 47C. If an inquiry finds non-compliance, the Commission President may give a compliance notice specifying action to take (AHRC Act s 35F); if it is not complied with, the President may apply to the Federal Court or the Federal Circuit and Family Court for an order directing compliance and any other order the court considers appropriate (s 35J). Section 47C is also enforceable through undertakings under Part 6 of the Regulatory Powers Act (s 35K)
