I've Been Underpaid

If you have been underpaid, you can usually recover up to six years of unpaid wages and entitlements. We explain how underpayments are worked out, where to claim, and what employers and the people behind them risk if they do not pay.

If you think you have been underpaid, you are not alone, and you do not have to accept it. Your employer must pay you at least what the law, your award or enterprise agreement, and your employment contract require. If it has not, you can usually recover the shortfall for up to six years back, with interest.

Underpayments happen in many ways. These are the ones we see most often:

The Wrong Award Rate

You are paid below the minimum for your award and classification, or you were never told which award or classification applies to you.

Penalty Rates And Overtime

Weekend, public holiday, evening and overtime rates are not paid, or a flat rate is paid that does not cover them.

Allowances

Uniform, laundry, meal, tool, travel and vehicle allowances that your award requires are not paid.

Casual Loading

You are engaged as a casual but the 25% casual loading (or the award's casual rate) is not paid.

Leave

Annual leave, personal leave or long service leave is not paid correctly, or untaken annual leave is not paid out when your job ends.

Superannuation

Superannuation guarantee contributions are paid late, paid short, or not paid at all.

Contract Pay, Bonuses And Commissions

Salary, bonuses or commissions promised in your contract are not paid, or unlawful deductions are taken from your pay.

Unpaid Trials And Unpaid Work

You are asked to work a trial shift, training or "work experience" without pay when it is really work.

Which system are you in? Most employees in WA work for a company (a Pty Ltd), and are covered by the Fair Work Act 2009 (Cth). This page is mainly about that system. If you work for a sole trader, a partnership, a trust run by individuals, a WA local council or the WA public sector, you are probably in the WA state system and your claim goes to the Industrial Magistrates Court instead. See Am I in the state or federal system? and the section on WA state system employees below.

What Your Employer Must Pay, And The Laws It Breaks If It Does Not

An underpayment claim under the Fair Work Act is a claim that your employer contravened a civil remedy provision. The most common are:

Award Entitlements

Not paying what your modern award requires is a breach of s 45 of the Fair Work Act 2009 (Cth).

Enterprise Agreement Entitlements

Not paying what a registered enterprise agreement requires is a breach of s 50.

The National Employment Standards

Not giving you your National Employment Standards entitlements (for example annual leave, personal leave, notice or redundancy pay) is a breach of s 44. See our guide to the National Employment Standards.

Paying In Full, In Money, At Least Monthly

Section 323 requires your employer to pay you in full, in money, at least monthly. It covers salary, bonuses, incentive payments, loadings, allowances, overtime and penalty rates, including for salaried and award-free employees.

Deductions And Requirements To Spend Money

Deductions are allowed only in the cases listed in s 324, such as a written authorisation principally for your benefit. Your employer (or a prospective employer) must not unreasonably require you to spend or pay money for its benefit (s 325).

Records And Pay Slips

Your employer must keep time and wages records (s 535) and give you a pay slip within one working day of paying you (s 536). The Fair Work Ombudsman says records must be kept for 7 years.

Superannuation

Your employer must make superannuation guarantee contributions for you: 12% of your qualifying earnings. Since 1 July 2026 (Payday Super) your employer must pay it with each pay, and it must reach your super fund within 7 business days of payday (there are some exceptions, such as for new employees). Since 1 January 2024 superannuation has been part of the National Employment Standards (s 116B of the Fair Work Act), so national system employees can claim unpaid super in the Fair Work small claims procedure, unless the Australian Taxation Office has already started proceedings for the same amounts. You can also report unpaid super to the Australian Taxation Office instead. If you work for a WA state-system employer, such as a sole trader, a partnership or some trusts, the National Employment Standards do not apply and unpaid super is generally pursued through the Australian Taxation Office.

Your employment contract can also give you more than the minimum. A promise in your contract that is not kept can be claimed as a breach of contract, and some contract amounts (called safety net contractual entitlements) can be claimed under the Fair Work Act itself.

How An Underpayment Is Worked Out

Every underpayment claim comes down to comparing what you were entitled to with what you were actually paid, pay period by pay period. In outline:

  1. Identify the instrument. Work out whether a modern award or an enterprise agreement covers your job, and which classification you fall into. The Fair Work Ombudsman's Pay and Conditions Tool and pay guides show the rates for each award. Our own simplified awards are a plain-English starting point.
  2. Reconstruct your hours. Use rosters, timesheets, pay slips, bank statements, messages and your own diary to show which days and hours you worked.
  3. Apply the rates for each period. Minimum rates change every year on 1 July, so use the rate in force at the time you did the work, then add penalty rates, overtime, allowances and loadings.
  4. Compare and total the shortfall. Subtract what you were actually paid, period by period, and add unpaid superannuation and leave.

We explain each step, with the traps, in our guide to calculating an underpayment.

If Your Employer Has Not Kept Proper Records

If your employer was required to keep a record or give you a pay slip about a matter and did not, then in a court claim for award, agreement or National Employment Standards entitlements it bears the burden of disproving your allegation about that matter, unless it has a reasonable excuse (s 557C of the Fair Work Act). This is why your own notes of your hours matter so much.

How Far Back You Can Claim

A court claim under the Fair Work Act must be started within 6 years after the day each contravention occurred (s 544). Each pay period is a separate contravention, so every month you wait, the oldest month of your claim can drop off. For a failure to pay out untaken annual leave, the six years runs from the end of your employment.

Interest

When a court orders an employer to pay an amount it owed you, it must add interest on application unless there is good cause not to (s 547).

Over-Award Salaries

If you are paid a salary above the award, your employer may argue that the extra pay covers overtime, penalties or allowances. Whether it does depends on what the payment was for under your contract, and the law on this is currently being tested on appeal. Do not assume a high salary means you have not been underpaid; get advice.

How An Underpayment Is Worked Out
Step 1: A Letter Of Demand

Most underpayments are resolved without going to court. The usual first step is a detailed letter to your employer setting out what you are owed, how it has been calculated, and what will happen if it is not paid by a set date.

A letter from a lawyer is often more effective than a letter you send yourself, because it shows the employer that you understand your entitlements and are prepared to enforce them. Our letters set out the calculation, the provisions breached, the personal exposure of the people involved, and the penalties a court can impose.

You can also ask the Fair Work Ombudsman for help. It is free, and its inspectors can investigate, issue a compliance notice requiring your employer to calculate and pay what is owed, and take employers to court. The Ombudsman does not act as your lawyer, and it chooses which matters to pursue.

Step 2: Get Your Records

Employers must keep time and wages records for 7 years, and must make them available to you if you ask, including after your employment has ended (Fair Work Ombudsman, record-keeping).

Pay slips must be given within 1 working day of pay day, and must contain the information the Fair Work Regulations require (pay slips).

Failing to keep records or give pay slips is itself a contravention, and it can shift the burden of proof onto the employer (see above).

Keep copies of everything you already have: your contract, pay slips, rosters, timesheets, bank statements and messages about shifts. Start writing down your usual hours now, while you remember them.

Step 2: Get Your Records
Where To Claim

The Small Claims Procedure

For amounts up to $100,000 (the cap since 1 July 2023), you can ask for your claim to be dealt with under the small claims procedure in s 548 of the Fair Work Act. It is run informally, without the strict rules of evidence, and lawyers can appear only with the court's permission. You can file in the Federal Circuit and Family Court of Australia (Division 2) or, in Western Australia, in the Industrial Magistrates Court, which hears Fair Work Act claims as an eligible State court. A small claim recovers what you are owed; it cannot impose penalties on your employer. Interest does not count towards the cap.

A Full Court Claim

Larger or more complex claims, and claims seeking penalties or orders against individuals, are brought in the Federal Circuit and Family Court or the Federal Court. The court can order your employer to pay what you are owed, compensation, interest and penalties, and can order that all or part of a penalty be paid to you.

Costs

In Fair Work Act claims each side usually pays its own legal costs, whatever the result. A court can order costs against a party only if it started proceedings vexatiously or without reasonable cause, or caused the other side costs through an unreasonable act or omission (s 570). That lowers the financial risk of bringing a genuine claim.

The People Behind The Business

Anyone involved in a contravention, such as a director, manager or HR officer who knowingly took part, is treated as having contravened the Act personally (s 550). Courts can impose penalties on them and in some cases order them to pay compensation. This matters if the company is struggling or has gone into liquidation.

Penalties, And When Underpayment Is A Crime

Maximum civil penalties increased from 27 February 2024, five-fold for many contraventions by employers with 15 or more employees, and a "serious contravention" now includes one that is knowing or reckless. From 1 January 2025, a larger employer's maximum penalty for an underpayment can in some cases be three times the amount underpaid, and intentional underpayment became a criminal offence (s 327A), with fines and, for individuals, up to 10 years' imprisonment. Only the Commonwealth Director of Public Prosecutions or the Australian Federal Police can prosecute it, usually on a referral from the Fair Work Ombudsman. Honest mistakes are not criminal, and a small business that complied with the Voluntary Small Business Wage Compliance Code will not be referred.

WA State System Employees

If you are in the WA state system, your award, industrial agreement and Minimum Conditions of Employment Act 1993 (WA) entitlements are enforced in the Industrial Magistrates Court under s 83 of the Industrial Relations Act 1979 (WA). You must apply within 6 years (s 82A), the court must order any underpayment it finds to be paid (s 83A), and since 31 January 2025 the maximum penalty is $18,000 for an individual and $93,000 for a company, ten times that for a serious contravention. You can also contact Private Sector Labour Relations (Wageline). A claim for a contract benefit that is not in an award goes to the WA Industrial Relations Commission instead. See underpayments in the WA state system and denied contractual benefits.

How We Can Help

We can work out what you are owed, write to your employer, request your records, and run your claim through to mediation or a hearing if it does not settle. Many claims settle once the calculation and the employer's exposure are laid out clearly, but every case is different. Read more about how we help with underpayments. If you think you have been underpaid, contact us for a free confidential discussion. Do not wait: every month of delay can cost you a month of your claim.
