How the Fair Work Ombudsman works, complaints, investigations and enforcement

Every Australian business that employs staff answers to the Fair Work Ombudsman. It is the federal agency responsible for promoting and enforcing compliance with the national workplace relations system, and it sits at one end of most serious disputes between employers and employees. If a worker says they have been underpaid, or a former employee lodges a complaint about their entitlements, the Fair Work Ombudsman is usually the first stop.

This article explains how the agency actually operates: who the key players are, how a matter becomes an investigation, what enforcement tools the regulator can deploy, what a breach can cost, and where a lawyer can make a difference. Most of it turns on the Fair Work Act 2009 (Cth) (the Act), which sets out the Ombudsman's functions and powers in detail, and on the regulator's own published approach to deciding what it will pursue.

Who does what: the players in the system

The Fair Work system has a handful of distinct actors, and it helps to know which is which before a dispute arrives:

The Fair Work Ombudsman: the office holder who heads the Office of the Fair Work Ombudsman, the agency established under Part 5-2 of the Fair Work Act 2009 (Cth). Under s 682 of the Act, its functions include promoting compliance with workplace laws and fair work instruments, providing education, assistance and advice, monitoring compliance, investigating conduct that may breach the Act, commencing court proceedings and making applications to the Fair Work Commission, and publishing a compliance and enforcement policy.
Fair Work Inspectors: the investigators. They are appointed by the Fair Work Ombudsman under s 700 of the Act and hold the statutory powers described below. They are the people who visit premises, ask questions and issue notices.
The Fair Work Commission: the separate national workplace relations tribunal. It is not the regulator. The Commission hears unfair dismissal and general protections disputes, approves enterprise agreements, and reviews modern awards. The Ombudsman enforces the law; the Commission adjudicates many of the disputes that arise under it.
The courts: the Federal Court, the Federal Circuit and Family Court of Australia and eligible state and territory courts impose penalties and other orders where contraventions are proven.
The Commonwealth Director of Public Prosecutions and the Australian Federal Police: they prosecute the criminal offences in the Act, such as intentional wage theft, on matters referred to them by the Ombudsman.

How a matter starts

The Fair Work Ombudsman does not investigate everything that crosses its desk. As its own compliance and enforcement page puts it, the agency makes the final decision on whether it investigates, guided by its priorities and its published Compliance and Enforcement Policy.

Matters usually come to the regulator's attention in one of three ways:

Complaints: An employee, a former employee, a union or another person reports a suspected breach. Complaints about unpaid wages, missed leave entitlements, or failure to meet award conditions are the most common.
Proactive compliance work: The Ombudsman conducts its own audits and targeted checks in priority industries, and it monitors trends across the economy.
Information sharing: The agency works with other regulators and with industry bodies, and it uses data to spot patterns such as systematic underpayment.

The regulator has said it maintains an enduring commitment to prioritise education and assistance for small business employers and for vulnerable or at-risk workers. That matters in practice: a small business that has made an honest mistake is far more likely to be steered toward fixing the problem than toward litigation, while deliberate or repeated conduct attracts much closer attention.

Investigation: what a Fair Work Inspector can do

Once a matter is accepted for investigation, Fair Work Inspectors hold significant statutory powers. Under s 709 of the Act, an inspector who is on premises may inspect any work, process or object, interview any person, require someone to produce records or documents, and inspect and copy records kept on the premises or accessible from a computer there.

Beyond a premises visit, the Ombudsman can issue a formal notice requiring a person to give information, produce documents, or attend to answer questions on oath or affirmation. Under s 712B of the Act, complying with such a notice is itself a legal obligation, and non-compliance can lead to further enforcement action.

For an employer, a few things are worth knowing about how this phase works:

Records are the centre of gravity: Employers are required to keep accurate time-and-wages records and to give employees payslips. An inspector will normally ask for those records first, and the way they are kept often determines how quickly a matter is resolved.
Interviews can be informal or formal: An inspector may simply ask questions on a site visit, or require a formal interview under a notice, where answers are given under oath or affirmation.
Obstructing an inspector is a bad idea: Refusing entry, destroying records, or hindering an investigation can itself attract consequences, separate from whatever breach was being investigated.
Cooperation is visible to the regulator: How an employer responds during an investigation feeds directly into how the Ombudsman chooses to resolve the matter, which is why legal advice at this stage is often the highest-value advice of all.

The enforcement ladder

The Fair Work Ombudsman has a graduated set of enforcement tools. Most matters are resolved at the lower rungs; court action is reserved for the minority. In rough order of severity:

Education and assistance: The regulator's default starting point is to explain the obligation and help the employer fix it. The Fair Work website holds free templates, fact sheets, pay calculators and best practice guides, and the Ombudsman provides advice directly to employers and employees.
Compliance notices: Under s 716 of the Act, if an inspector reasonably believes a person has contravened a provision of the National Employment Standards, a modern award, an enterprise agreement or a similar instrument, the inspector may issue a notice requiring the person to take specified action to remedy the direct effects of the contravention within a reasonable time. A compliance notice typically requires the employer to back-pay the amounts owed and to produce evidence that it has done so. Failure to comply can escalate the matter to court.
Enforceable undertakings: Under s 715 of the Act, where the Ombudsman reasonably believes a person has contravened a civil remedy provision, it may accept a written undertaking from the person. An undertaking sets out the steps the employer commits to take, such as back-paying employees, engaging an external auditor, or changing payroll systems. While an undertaking is in force, an inspector cannot apply to court for orders in relation to the same contravention, which is what makes an undertaking attractive to both sides: the employer avoids litigation, and the regulator secures a binding commitment.
Court proceedings: Where conduct is serious, repeated, deliberate or uncooperative, the Ombudsman can commence proceedings in the Federal Court or the Federal Circuit and Family Court, or make applications to the Fair Work Commission. Courts can order pecuniary penalties under s 546 of the Act and compensation orders that require the employer to pay what workers are owed.
Criminal referral: For the most serious conduct, the Ombudsman can refer matters to the Commonwealth Director of Public Prosecutions or the Australian Federal Police for criminal prosecution.

What non-compliance can cost

The dollar figures attached to workplace contraventions have climbed sharply, and they are worth knowing precisely because the maximums are so much larger than most business owners expect.

Most contraventions of the Act's core obligations, such as failing to comply with the National Employment Standards or a modern award, carry a maximum penalty of 60 penalty units per contravention for an individual and 300 penalty units for a body corporate, since a company pays five times the individual maximum. A penalty unit is currently valued at $330, which puts the standard maximums at around $19,800 for an individual and $99,000 for a company per contravention. Where multiple employees and multiple pay periods are involved, the exposure multiplies quickly, although the Act's course-of-conduct rules can treat a pattern of similar contraventions as a single contravention for penalty purposes.

Serious contraventions are a different league. Under s 557A of the Act, a contravention is serious where the person knowingly contravened the provision or was reckless as to whether the contravention would occur. The maximum penalty jumps to 600 penalty units for an individual and 3,000 penalty units for a body corporate, or around $198,000 and $990,000 respectively.

For underpayments specifically, the Act now goes further. Under s 546A and s 546(2A) of the Act, where a body corporate that is not a small business employer contravenes a provision in connection with an underpayment, the maximum penalty can be calculated as a multiple of the underpayment amount, up to three times what was not paid.

And since 1 January 2025, intentional wage theft is a criminal offence. Under s 327A of the Act, an employer who intentionally fails to pay an amount that is due faces, for an individual, up to ten years' imprisonment or a fine, or both. The maximum fine is the greater of three times the underpayment amount and 5,000 penalty units, and for a body corporate, 25,000 penalty units. The Ombudsman's published position is that honest mistakes are not a criminal offence; the offence targets deliberate non-payment.

There is also a reputational dimension. Court outcomes are public, enforcement activity is regularly reported in the media, and a finding against a business can affect tenders, licences and relationships with employees and customers. For many businesses the reputational cost outweighs the penalty itself.

Where employers trip up

The patterns that lead businesses into serious trouble are consistent, and most are avoidable:

Missing or sloppy records: When records do not exist or do not add up, an employer cannot easily rebut a claim about hours worked or rates paid. Poor records are often what converts a small dispute into a formal investigation.
Ignoring the regulator's correspondence: Matters rarely disappear if left alone. A compliance notice or a request for information that goes unanswered is a fast route up the enforcement ladder.
Misclassifying workers: Treating employees as independent contractors, or applying the wrong award, creates underpayment exposure that can go unnoticed for years and then surface as a large back-pay bill.
Falling out of date: Awards and minimum rates change, and obligations such as superannuation and leave accruals shift over time. Payroll systems that are not updated are a common source of accidental non-compliance.
Not self-correcting: The regulator has built incentives for early correction. The Voluntary Small Business Wage Compliance Code, for example, sets out how a small business can self-correct an underpayment, and under s 327B of the Act, the Ombudsman must not refer conduct to prosecutors where a small business employer has complied with the Code. The Ombudsman can also enter cooperation agreements with employers who come forward, in exchange for reduced enforcement action.

When a lawyer should be involved

The points in the process where legal input changes the outcome are specific, and they come earlier than most business owners assume:

When an employee first raises a complaint internally: A lawyer can help you assess the claim, check the records, and decide whether to correct the issue before the regulator becomes involved.
Before responding to an inspector or a formal notice: What you say in an interview, and what documents you produce, can be used later. Advice on how to cooperate without creating avoidable exposure is the core of a lawyer's role here.
When a compliance notice or enforceable undertaking is proposed: The terms of an undertaking are negotiable to a degree, and an experienced employment lawyer can shape them so that the business can realistically comply and the matter can be closed.
If court proceedings commence: A lawyer will run the defence, make submissions on penalty, and seek to resolve the matter on the best available terms.

An employment lawyer also earns their fee before any dispute exists, by reviewing pay structures, contractor arrangements and record-keeping practices so that an audit or complaint does not become an investigation in the first place.

Why early action changes the outcome

The pattern across the Fair Work Ombudsman's enforcement activity is clear: the matters that end in court, in large penalties and in criminal referral share two features. The conduct was deliberate or reckless, and the employer's records could not tell a credible story. Everything else is usually resolved through correction, undertakings and cooperation, often with the regulator's encouragement.

That means the leverage in this system sits with the employer who acts before enforcement starts. Fix an underpayment when it is found, keep records that would survive an audit, respond promptly to the regulator, and seek advice at the complaint stage rather than the courtroom stage. For small businesses, the statutory protections for self-correction make early action even more valuable. A consultation with an employment lawyer to check your wage practices is far cheaper than the least expensive penalty, and it is the most direct way to keep the Ombudsman's attention elsewhere.
