AI and Wage Theft: How Automated Payroll Gets It Wrong in Australia
Automated payroll systems cause widespread underpayment in Australia. Your employer is still liable for AI payroll errors. Learn how to check your pay and recover what you're owed.
How automated payroll systems are getting it wrong
Australia's award system is one of the most complex pay structures in the world, with over 120 modern awards, each containing detailed provisions for base rates, penalty rates, overtime, allowances, loadings, and classification structures. Payroll software must correctly interpret and apply all of these rules — and it frequently gets it wrong. Major Australian companies including Woolworths, Commonwealth Bank, Super Retail Group, Qantas, and ABC have all disclosed significant underpayment scandals traced to payroll system errors. The underpayments across corporate Australia have totalled billions of dollars. Common AI payroll errors include misclassifying employees under the wrong award, failing to apply correct penalty rates for evenings, weekends, and public holidays, incorrectly calculating overtime thresholds, missing allowance entitlements, and failing to update rates when awards are varied by the Fair Work Commission.
Why AI payroll still cannot handle Australian awards properly
The complexity of Australian modern awards presents a unique challenge for payroll automation. A single employee's pay rate can vary depending on their classification level, the day of the week, the time of day, whether it is a public holiday, whether they are casual or permanent, whether they have worked more than a certain number of hours, whether a meal break was provided, and whether they are required to work at a particular location. Some awards have dozens of pay rates for a single classification. AI payroll systems use rules engines to interpret these awards, but the rules must be programmed correctly, updated when awards change, and configured for each employer's specific circumstances. When a payroll provider misinterprets an award clause — or fails to update the system after the Annual Wage Review — the error can affect thousands of employees over years before it is detected.
Your employer is liable — not the payroll software
A critical legal principle is that the employer, not the payroll software provider, is responsible for paying employees correctly. Under the Fair Work Act, it is the employer's obligation to ensure compliance with the National Employment Standards, the applicable modern award or enterprise agreement, and any employment contract. If a payroll system calculates the wrong rate, the employer cannot blame the software vendor to avoid liability. The Fair Work Ombudsman has been clear: outsourcing payroll does not outsource legal obligations. Since 2025, the criminal wage theft provisions in the Fair Work Act make it an offence for an employer to intentionally engage in a systematic pattern of underpaying employees. Even where underpayment is not intentional, the employer faces civil penalties of up to $93,900 per contravention for individuals and $469,500 for corporations. The message is clear: employers must audit their payroll systems.
How to check if your pay is correct
Every Australian employee should periodically verify their pay against their award or agreement entitlements. Start by identifying your correct modern award — use the Fair Work Ombudsman's Find My Award tool or our Award Finder. Confirm your classification level within the award. Check the current base rate for your classification on the Fair Work Commission's pay guide for your award. Calculate what you should be paid for ordinary hours, overtime, weekends, public holidays, and evening shifts based on the penalty rate schedule in your award. Compare this to your payslip. Check that superannuation is being calculated correctly at 12% of ordinary time earnings. Verify that allowances — such as uniform, tool, or travel allowances — are being paid where applicable. Our Payslip Scanner tool can help you quickly identify discrepancies between what you are being paid and what your award requires.
Recovering underpaid wages — the process
If you discover that you have been underpaid due to a payroll system error, you can recover the full amount owed. Under the Fair Work Act, there is a 6-year limitation period for recovering underpaid wages. Start by raising the issue with your employer in writing, setting out the specific underpayment and the period affected. Many employers will rectify payroll errors voluntarily once they are identified. If your employer disputes the underpayment or refuses to pay, contact the Fair Work Ombudsman on 13 13 94 or lodge a complaint online. The Ombudsman can investigate, issue compliance notices, and in some cases commence legal proceedings on your behalf. You can also bring your own claim in the Federal Circuit and Family Court or a state magistrates court. Keep all payslips, employment records, rosters, and time sheets as evidence. Your union can also assist with wage recovery claims.
Employer obligations to audit payroll systems
Following the wave of corporate underpayment scandals, there is now a strong expectation — and in some cases a legal obligation — for employers to proactively audit their payroll systems. The Fair Work Ombudsman's Compliance and Enforcement Policy prioritises employers who have not taken reasonable steps to ensure compliance. The Respect@Work and Closing Loopholes reforms have strengthened employer accountability. Best practice for employers includes conducting an annual payroll compliance audit against the applicable award or agreement, testing the payroll system after every award variation (particularly after the Annual Wage Review in July), engaging independent payroll auditors for complex award structures, maintaining a process for employees to raise pay queries without fear of reprisal, and self-reporting any identified underpayments to the Fair Work Ombudsman. Employers who self-report and promptly rectify underpayments are treated more favourably than those who conceal or ignore the issue.
