How Australia's industrial relations system works

Every Australian employer sits inside the same layered system for setting what employees are paid and what they get. At the bottom is a set of minimum standards that apply to nearly every employee, no matter what is signed. On top of that, industry awards add pay rates and conditions, enterprise agreements can tailor the deal further, and contracts of employment can add extras. Each layer can only ever move things up, never down.

Understanding how those layers fit together matters because the consequences of getting them wrong are no longer just back-pay orders. Since 1 January 2025, deliberately underpaying an employee can be a criminal offence. This article walks through how the system works, who runs it, and where employers most often get caught.

Who does what in the system

Three institutions do most of the heavy lifting, and it helps to keep them straight because employers deal with all three at different points:

Fair Work Commission (FWC): the national tribunal. It makes and varies modern awards, approves enterprise agreements, runs the annual minimum wage review, and hears disputes including unfair dismissal claims.
Fair Work Ombudsman (FWO): the enforcement and education regulator. It answers pay questions, audits employers, issues compliance and infringement notices, and can take court action for underpayments. Since 2025 it can also refer intentional underpayment for criminal prosecution.
Courts: the Federal Court and Federal Circuit and Family Court impose civil penalties and, for the new criminal offence, can impose fines and imprisonment.

Employers and employees (often represented by unions or employer associations) are the parties the system regulates. Most private sector employers in Australia are in the national system created by the Fair Work Act 2009 (Cth) (the Fair Work Act). A small number of private employers, mainly in Western Australia, remain in a separate state system, so the first question is always which system you are in.

The National Employment Standards: the non-negotiable floor

The base of the whole system is the National Employment Standards (the NES), set out in Part 2-2 of the Fair Work Act. Section 61 makes the point bluntly: these are minimum standards that cannot be displaced, even by an enterprise agreement. The NES bundles the following key entitlements:

Maximum weekly hours: a full-time employee cannot be required to work more than 38 hours a week, and a part-time employee more than their ordinary hours, unless the additional hours are reasonable. Employees can refuse unreasonable additional hours, and the reasonableness test weighs factors like health and safety, family responsibilities and the needs of the workplace.
Flexible working arrangements: employees who are pregnant, parents or carers of a child of school age or younger, carers, have a disability, are 55 or over, or are affected by family and domestic violence can request changes to their hours, patterns or location of work. The old 12-month qualifying period was removed in 2023, so an employee can ask from the start of employment. The employer must respond in writing within 21 days and can only refuse after genuinely discussing the request, on prescribed business grounds.
Parental leave: employees with at least 12 months of continuous service get up to 12 months of unpaid parental leave around the birth or adoption of a child, and can request a further extension of up to 12 months, capped at 24 months after the birth or placement. This is separate from the federal government's Paid Parental Leave payment, which is paid by Services Australia rather than the employer.
Annual leave: four weeks of paid annual leave per year of service, with five weeks for shiftworkers, accruing pro rata for part-time employees. Casuals do not accrue paid annual leave.
Personal, carer's and compassionate leave: permanent employees get 10 days of paid personal (sick and carer's) leave per year, which accumulates. All employees, including casuals, get two days of unpaid carer's leave per occasion and two days of compassionate leave per occasion.
Family and domestic violence leave: all employees, including casuals, get 10 days of paid family and domestic violence leave in each 12-month period. It is available in full at the start of each period and does not accumulate.
Community service leave: unpaid leave for jury service and voluntary emergency management activities, with no set limit. Non-casual employees are also entitled to make-up pay for jury service for up to 10 days.
Long service leave: the NES preserves the long service leave schemes in each state and territory, so the entitlement an employee builds up depends on where they work and the applicable state law.
Public holidays: employees are entitled to be absent on public holidays in their location, and to be paid for the hours they would normally have worked. An employer can request work on a public holiday, but only if the request is reasonable, and an employee can refuse if the request, or their refusal, is reasonable.
Notice of termination and redundancy pay: ending an employee's employment requires written notice, or payment in lieu, on a scale that grows with service and age, from one week for up to a year of service up to five weeks for an employee aged over 45 with more than five years' service. Genuine redundancy triggers redundancy pay of between four weeks (one to two years' service) and 16 weeks (nine to ten years' service), with exceptions for casuals and for small business employers with fewer than 15 employees.
Fair Work Information Statement: every new employee must be given the Fair Work Information Statement before or as soon as practicable after they start, and casuals must also receive the Casual Employment Information Statement.

The NES is the floor, but it is not the whole picture. For most employees the entitlements that actually get paid out, penalty rates, allowances and overtime, come from the next layer.

Modern awards: the industry layer

Modern awards are legal instruments made by the FWC that set out the minimum pay rates and conditions for an industry or occupation. They came into effect on 1 January 2010, replacing the patchwork of federal and state awards, and there are now about 121 of them, from the General Retail Industry Award to the Clerks Private Sector Award and the Building and Construction General On-site Award.

A modern award typically covers minimum hourly rates, classifications and pay grades, ordinary hours and rosters, breaks, allowances, penalty rates and overtime. It applies to employers and employees in the national system who perform work covered by the award. Working out which award applies is usually a matter of reading the award's coverage clause and classification definitions, and the FWO's Find my award tool and Pay and Conditions Tool can do a lot of that work for you.

A few things about award coverage regularly surprise employers:

Managers and high earners may fall outside: A modern award can apply to an industry without covering every employee in it. Employees whose role is managerial, or who earn above the high income threshold, may not be covered even where a relevant award exists. The high income threshold for 2025-26 is $183,100, and it is indexed each year.
Award-free employees exist: Where no award and no registered agreement covers an employee, they are "award and agreement free". Their minimums are the NES plus the national minimum wage, and the FWO fact sheet confirms that in that situation the NES and the National Minimum Wage form the minimum terms and conditions.
Classification levels matter: Each award divides roles into classification levels based on duties, qualifications and experience. Two employees doing similar work in the same business can sit in different levels with different minimum rates, which is one of the most common sources of underpayment.

Enterprise agreements: tailoring, within limits

An enterprise agreement is a document negotiated between an employer and its employees (usually with a bargaining representative such as a union) that replaces the relevant modern award for the employees it covers. It lets a business trade the award's penalty rates or rostering rules for arrangements that suit the operation, such as a flat higher hourly rate that already builds in weekend work.

The catch is the better off overall test (the BOOT). Under section 193 of the Fair Work Act, the FWC can only approve an agreement if it is satisfied that each award-covered employee covered by the agreement would be better off overall under the agreement than under the relevant modern award. This is assessed at approval time, and it is a genuine comparison of the whole package, not just the base rate.

Two practical points follow for employers thinking about an agreement:

The agreement only operates once the FWC approves it, and it continues to apply after its nominal expiry date until it is replaced or terminated.
Because award rates are reviewed every year and typically increase on 1 July, an agreement that passed the BOOT at approval can quietly fall behind. The FWO is clear on the result: if the base rates in the agreement drop below the award rates, the award base rates apply. Businesses with agreements should re-check their rates against the award after every annual wage review.

Enterprise agreements were once common, but agreement-making has declined sharply over the past decade, and most small and medium businesses today rely on the NES plus a modern award rather than an agreement.

Contracts of employment: the top layer

Finally, an employment contract sits on top of the statutory layers. It can add entitlements, such as extra leave, a notice period longer than the NES minimum, or a bonus structure, and it typically records hours of work, probation, duties, confidentiality and intellectual property, restraint terms and termination arrangements.

What a contract cannot do is undercut the layers beneath it. A clause that tries to contract out of the NES is ineffective under section 61, and a rate below the award or agreement minimum is still an underpayment no matter what the signed contract says. Contract terms are enforceable only to the extent they sit above the statutory floor, which is why a well-drafted contract is written with the applicable award in mind rather than in isolation.

Where the system bites: enforcement and the new wage theft offence

The FWO is the regulator most employers will meet. It runs proactive audits, responds to complaints, and has a growing menu of enforcement tools: infringement notices, compliance notices, enforceable undertakings, and court proceedings seeking civil penalties and back-pay orders. Getting caught is expensive even before penalties, because underpayments must be paid in full with interest, often across several years and many employees.

The stakes rose on 1 January 2025, when intentionally underpaying an employee's wages or entitlements became a criminal offence under the Fair Work Act. The offence targets deliberate conduct, not honest mistakes, and individuals convicted can face fines and imprisonment. Small businesses that comply with the Voluntary Small Business Wage Compliance Code have a statutory defence, but the burden is on the employer to show genuine attempts to get it right. A record-keeping or classification error can now be the difference between a civil back-pay order and a criminal referral.

When you need a lawyer

Most of the value a workplace lawyer adds is before anything goes wrong. The areas where employers most often need help are:

Award identification and classification: Reading a coverage clause and matching roles to classification levels is genuinely technical, and getting it wrong underpays employees from day one. A lawyer can map your workforce to the award and check that pay rates, penalty rates and allowances line up.
Enterprise agreements: Drafting an agreement that passes the BOOT, running the better off overall comparison, and managing the FWC approval process are not do-it-yourself tasks, and the FWC's scrutiny has increased in recent years.
Contracts and high earners: Structuring employment contracts, including for employees near or above the high income threshold, requires care so that the package works with, not against, the statutory layers.
Responding to the FWO: If an audit letter, compliance notice or investigation arrives, how you respond matters. Early legal input can limit the scope of an investigation, correct the underpayment promptly, and protect against the matter escalating to prosecution.
Terminations and redundancies: Working out whether a dismissal is a genuine redundancy, whether notice and redundancy pay are correct, and whether an unfair dismissal claim is likely, is where a lawyer earns their fee.

The floor moves every July

The part of this system that most often defeats employers is that it is not static. Award rates are re-set each year in the FWC's annual wage review, the high income threshold is indexed, and the law itself keeps changing, as it did with flexible work in 2023, family and domestic violence leave, and the wage theft offence in 2024 and 2025. An employment arrangement that was correct when it was signed can be below the minimum three years later, and the employer is the one who carries that risk.

The cheapest fix is a compliance review now, before an employee complains or an audit letter arrives. Checking that each employee is under the right award, at the right classification, being paid at least the current minimums and receiving the statements they are owed, is a contained piece of work, and it is usually far less expensive than a back-pay order with interest, let alone a criminal investigation. A short consultation to check your classification and award coverage will tell you where you stand, and a lawyer can run the review, fix the gaps and set up a process for the next 1 July.
