A Guide to Criminal Underpayment Laws in Australia

Written by Mathew French | 25 August 2025

As of 1 January 2025, wage theft isn't just a civil matter anymore – it's become a criminal offence that can land employers in prison for up to 10 years. This is the most significant change to workplace compliance in decades for HR professionals across Australia. 

The new criminal underpayment laws under the Fair Work Act 2009 have created a two-tier system where honest mistakes remain civil matters, but intentional wage theft now carries criminal penalties that rival those for serious fraud.

What makes this particularly challenging is that these laws don't just apply to blatant cases of wage theft. They can capture patterns of conduct that began before 1 January 2025, meaning historical underpayments could suddenly become criminal matters if they're part of ongoing deliberate conduct. The stakes have never been higher, and the time for action is now.

Read on to find out everything you need to know about wage theft laws and criminal underpayment in Australia ⬇️

The Scale of the Problem: Why These Laws Were Necessary

The introduction of criminal penalties was a response to a massive and growing problem. According to the Australian Council of Trade Unions, wage theft affects over one million Australian workers, with particularly severe impacts on vulnerable groups including women, young people, and migrant workers.

The Fair Work Ombudsman's own data tells a sobering story. In the three years leading up to these reforms, the FWO recovered more than $473 million in unpaid wages and entitlements for workers. The Super Members Council estimates that unpaid superannuation alone cost workers $5.1 billion in 2021-22, with cumulative losses of almost $41.6 billion over nine years.

The key numbers are ⬇️

  • 875,000 casual workers (one in three) experience wage theft
  • 538,200 permanent workers are affected by underpayments
  • $1.5 billion recovered by the FWO in three years (2022-2024)
  • $41.6 billion in unpaid superannuation over nine years
  • 29% of Fair Work prosecutions involve the hospitality sector, despite it comprising only 7.2% of the workforce

This represents real people whose financial security has been undermined by employers who view wage theft as a business strategy rather than a crime.

How to Legal Framework Has Changed

The Fair Work Legislation Amendment (Closing Loopholes) Act 2023

The criminal underpayment provisions were introduced through the Fair Work Legislation Amendment (Closing Loopholes) Act 2023, which received Royal Assent on 14 December 2023. The centrepiece of these reforms is the new Section 327A of the Fair Work Act 2009, which creates the criminal offence of intentional underpayment.

Under Section 327A, an employer commits a criminal offence if they:

  • Are required to pay an amount to an employee under the Fair Work Act or an industrial instrument (such as wages, allowances, superannuation, or leave entitlements)
  • Intentionally engage in conduct that results in failure to pay these amounts in full
  • Fail to make the payment on or before the due date

The key word here is "intentionally". This isn't about genuine mistakes or system errors – it's about deliberate conduct designed to avoid paying employees what they're legally owed.

What Constitutes a "Required Amount"

The legislation casts a wide net over what constitutes a "required amount". According to the Fair Work Ombudsman, this includes:

  • Base wages and salaries
  • Penalty rates and overtime payments
  • Allowances and bonuses
  • Leave entitlements (annual leave, sick leave, long service leave)
  • Superannuation contributions
  • Salary sacrifice arrangements

Essentially, if the Fair Work Act or an industrial instrument requires you to pay it, it's covered by the criminal provisions.

The Corporate Culture Element

One of the most significant aspects of these new laws is how they attribute criminal liability to corporations. Unlike other parts of the Fair Work Act, the criminal underpayment provisions use the Criminal Code Act 1995 (Cth) to determine corporate liability.

This means a corporation can be criminally liable if it can be proved that:

  • A corporate culture existed that directed, encouraged, tolerated, or led to non-compliance with wage obligations
  • The corporation failed to create and maintain a culture that required compliance with wage obligations

Corporate Culture and Personal Liability

One of the most groundbreaking aspects of these laws is how they establish personal liability for corporate executives and HR professionals. Recent cases have shown that the "turning a blind eye" defence no longer holds water. HR managers have been personally fined amounts ranging from $92,232 to $105,084 for knowing about underpayments and failing to act.

The corporate culture test means that companies can be held criminally liable if they fail to establish and maintain a culture that promotes wage compliance. This means demonstrating through actions and systems that wage compliance is a genuine priority.

Key factors in establishing corporate culture include:

  • Senior management commitment to wage compliance
  • Adequate resources allocated to payroll functions
  • Regular training and awareness programs
  • Appropriate systems and processes
  • Swift action to address identified issues
  • Clear consequences for non-compliance

The Six-Year Limitation Period

Criminal proceedings for wage theft must be commenced within six years of the offence. While this provides some certainty for employers, it also means that current underpayment issues could potentially be prosecuted well into the future. For HR professionals, this emphasises the importance of addressing compliance issues immediately rather than hoping they'll be forgotten over time.

The Penalties: What's at Stake

Criminal Penalties

The criminal penalties for wage theft are severe and designed to act as a significant deterrent:

For individuals:

  • Maximum prison sentence: 10 years
  • Maximum fine: $1.565 million OR three times the underpayment amount (whichever is greater)

For corporations:

  • Maximum fine: $8.25 million OR three times the underpayment amount (whichever is greater)

The Voluntary Small Business Wage Compliance Code: A Lifeline for SMEs

Who Qualifies as a Small Business

The Voluntary Small Business Wage Compliance Code provides crucial protection for businesses with fewer than 15 employees. This threshold is consistent with other Fair Work Act provisions and is calculated based on the number of employees at the time of the underpayment.

Protection Mechanisms: Beyond the Small Business Code

While the Voluntary Small Business Wage Compliance Code provides crucial protection for businesses with fewer than 15 employees, all employers can benefit from understanding the broader protection mechanisms available.

The Code Assessment Process: The Fair Work Ombudsman doesn't use a simple checklist approach. Instead, they conduct a holistic assessment of an employer's conduct, considering factors such as:

  • Whether the employer sought appropriate advice about their obligations
  • The adequacy of payroll systems relative to business complexity
  • Response time and approach to rectifying identified issues
  • Level of cooperation with Fair Work investigations
  • Implementation of recommended improvements

Critical Limitation: The Code only protects against criminal prosecution – it doesn't prevent civil penalties, compliance notices, or other enforcement actions. This means small businesses can still face significant financial penalties even if they avoid criminal charges.

Beyond Small Business: Larger employers can't rely on the Code, but they can still demonstrate good faith through:

  • Proactive compliance audits
  • Investment in appropriate payroll systems
  • Regular legal compliance reviews
  • Swift remediation of identified issues
  • Cooperation with Fair Work investigations

Enforcement Mechanisms: Who's Watching and How

The Fair Work Ombudsman's Role

The Fair Work Ombudsman (FWO) plays a crucial role in the new enforcement framework. While they cannot initiate criminal prosecutions directly, they have the power to:

Strategic Enforcement Approach

The Fair Work Ombudsman has developed a sophisticated enforcement strategy that prioritises cases based on their potential impact and deterrent value. Understanding this approach helps HR professionals assess their risk profile and compliance priorities.

High-priority cases:

  • Systematic underpayment schemes affecting multiple employees
  • Cases involving vulnerable workers (young people, migrants, women)
  • Repeat offenders with previous compliance histories
  • Large-scale financial impact (typically over $50,000 in underpayments)
  • Cases with significant industry-wide deterrent value

Investigation process:

  1. Initial Assessment: FWO reviews complaints and determines investigation priority
  2. Evidence Gathering: Detailed examination of payroll records, employee interviews, workplace inspections
  3. Employer Response: Opportunity for employers to explain and remediate issues
  4. Decision Making: Assessment of whether criminal referral is appropriate based on evidence and public interest
  5. Referral or Alternative Action: Criminal referral to CDPP/AFP or civil enforcement action

Timeline considerations:

  • Initial investigations typically take 3-6 months
  • Complex cases can extend to 12-18 months
  • Criminal prosecutions may take 2-3 years from initial complaint to resolution
  • Civil enforcement actions are generally resolved within 6-12 months

The Public Interest Test

The public interest test is crucial in determining which cases proceed to criminal prosecution. According to the Fair Work Ombudsman's Compliance and Enforcement Policy, factors considered include:

  • The seriousness of the alleged offence
  • The harm caused to employees
  • The employer's conduct and level of cooperation
  • Whether the employer has previously contravened workplace laws
  • The deterrent effect of prosecution
  • The availability of alternative enforcement options

Investigation Powers

The FWO has significant investigation powers, including the ability to:

  • Require employers to produce records and documents
  • Conduct interviews with employees and employers
  • Enter workplaces to inspect records
  • Require attendance at hearings

These powers are the same whether the investigation is for civil or criminal matters, but the stakes are obviously much higher for criminal investigations.

Cooperation Agreements: The Self-Reporting Pathway

What Are Cooperation Agreements

Cooperation agreements represent a significant opportunity for employers who discover they may have committed criminal underpayment offences. These are written agreements between the employer and the Fair Work Ombudsman that provide protection from criminal prosecution in exchange for voluntary disclosure and cooperation.

The Benefits of Self-Reporting

Employers who voluntarily report potential criminal conduct can seek to enter into a cooperation agreement, which:

  • Prevents referral for criminal prosecution for the specific conduct covered by the agreement
  • Demonstrates good faith and cooperation
  • May influence the FWO's approach to civil enforcement
  • Provides certainty about the scope of protection

However, cooperation agreements don't prevent the FWO from taking civil enforcement action, and they don't provide blanket protection for future conduct.

Advanced Cooperation Strategies

Beyond the basic cooperation agreement framework, sophisticated employers are implementing advanced strategies to demonstrate good faith and reduce legal risk.

Early Warning Systems:

  • Regular payroll reconciliations with award rates
  • Automated alerts for unusual payment patterns
  • Employee feedback mechanisms for pay queries
  • Cross-referencing with industry benchmarks

Proactive Disclosure Programs:

  • Voluntary compliance audits by external specialists
  • Self-reporting of identified issues before employee complaints
  • Implementation of recommended improvements
  • Regular updates to the Fair Work Ombudsman on remediation progress

Documentation Standards:

  • Comprehensive records of all payroll decisions and calculations
  • Clear audit trails for rate changes and adjustments
  • Evidence of advice sought and received
  • Documentation of system improvements and staff training

Industry Collaboration:

  • Participation in industry wage compliance initiatives
  • Sharing of best practices with other employers
  • Collaborative approaches to complex award interpretation issues
  • Joint training programs and resource development
