Performance Reviews: Legal Considerations for Australian Employers and How to Protect Your Business

Performance reviews are a powerful way to set expectations, recognise achievements and reset goals with your team. When they’re done well, they support engagement and productivity. When they’re done poorly, they can create risk.

In Australia, a performance review isn’t just a chat - it’s a process with legal implications. The way you plan, conduct and document reviews can influence how defensible your decisions are if a dispute arises later.

In this guide, we’ll walk through the key legal considerations for Australian employers, common pitfalls to avoid, and practical steps to protect your business while keeping reviews constructive and fair.

What Is a Performance Review and Why Does It Matter?

A performance review is a structured discussion between an employer (or manager) and an employee about how the employee is tracking against their role. Reviews are often annual, semi-annual or quarterly, and they typically assess achievements, performance against KPIs, strengths, areas for development and next steps.

Done right, a review should be:

• Objective and tied to the position description and agreed KPIs
• Two-way (employees should have a chance to respond, raise concerns and set goals)
• Well-documented, with clear action items, support measures and timelines

Why it matters legally: your review notes sit within your personnel records and can become evidence of what was discussed and agreed. If you later need to manage underperformance or defend a claim, clear records can make a real difference.

Are Performance Reviews Legally Required in Australia?

There’s no general legal requirement under the Fair Work Act 2009 (Cth) or the National Employment Standards to conduct performance reviews. They’re considered best practice rather than mandatory.

However, consider these points:

• Internal commitments: if your contracts or workplace policies say you will conduct regular reviews, follow through consistently.
• Industrial instruments: some enterprise agreements refer to consultation, feedback or performance processes. It’s less common for modern awards to mandate formal reviews, but always check what applies to your workforce.
• Risk management: regular, consistent reviews help demonstrate procedural fairness and improve your chances of defending a later decision about performance management or termination.

In short: you’re not legally forced to run reviews, but having a robust process is one of the simplest ways to lift performance and reduce legal risk.

Legal Risks to Watch (And How to Minimise Them)

Most performance reviews go smoothly. Problems tend to arise where process and documentation are weak, or where reviews are used in a way that looks punitive or inconsistent. Key risks include:

Unfair Dismissal Risk

If you eventually dismiss an employee for unsatisfactory performance, the Fair Work Commission will look at whether the dismissal was harsh, unjust or unreasonable. The factors in section 387 of the Fair Work Act include whether the employee was notified of performance issues, given a chance to respond and a reasonable opportunity to improve.

Importantly, you shouldn’t unreasonably refuse an employee’s request to have a support person present at discussions about termination - this is one factor the Commission may consider (though it’s not an absolute right at every meeting).

General Protections (Adverse Action)

You can’t take adverse action (for example, disciplinary action or dismissal) because an employee exercised a workplace right, made a complaint or inquiry, took sick leave, or engaged in industrial activity. If performance concerns arise shortly after a complaint, be doubly careful to ensure your process is fair, evidence-based and not retaliatory.

Discrimination and Equal Opportunity

Performance reviews must not be influenced by protected attributes such as age, sex, race, disability or family responsibilities. If health or disability is relevant, consider reasonable adjustments to the role or expectations where required and ensure decisions are based on objective, job-related criteria.

Bullying or Psychological Safety

A review delivered in a hostile or belittling manner can contribute to bullying allegations. Keep the conversation respectful, private and focused on conduct and outcomes, not personal traits.

Privacy and Record-Keeping

Review notes belong in personnel records and should be stored securely. Consider whether your current practices align with your Employee Privacy Handbook and any policies about access, retention and correction. For broader obligations around keeping information, have a look at data retention laws in Australia.

Small Business Fair Dismissal Code

If you have fewer than 15 employees, the Small Business Fair Dismissal Code may apply. While it doesn’t require formal reviews, following a clear, fair process - warning the employee, explaining the issue and giving a chance to improve - will help you meet the Code’s intent and defend decisions.

How to Run a Fair and Defensible Performance Review

Here’s a practical framework you can adopt and tailor to your business. It’s designed to be simple, consistent and defensible if things get tricky later.

1) Plan and Set Expectations Early

• Ensure the role description and KPIs are clear and current.
• Share the review criteria ahead of time so there are no surprises.
• If you’ve promised reviews in an Employment Contract or handbook, diarise them and keep to the schedule.

2) Gather Evidence (Not Just Opinions)

• Review KPIs, work outputs, quality metrics, attendance data and documented feedback from relevant stakeholders.
• Cross-check against the agreed performance standards for the review period.
• Avoid relying on hearsay; if you receive third-party feedback, capture it accurately and fairly.

3) Conduct the Meeting With Procedural Fairness

• Hold the discussion in private and allow enough time for a proper conversation.
• Use clear, respectful language and reference specific examples.
• If the meeting could result in formal warnings or starts a performance management process, consider offering a support person.

4) Be Clear, Specific and Action-Oriented

• Identify strengths and wins - this builds engagement and trust.
• For concerns, state the gap, why it matters and what “meeting the standard” looks like.
• Agree on next steps with timelines, measurable goals and any support (training, mentoring, workload adjustments).

5) Document Everything

• Record the date, attendees and key points discussed. Include the agreed action plan and review dates.
• Provide a copy to the employee and allow them to add comments if your process allows.
• Store the record securely as part of your HR files, consistent with your privacy and retention settings.

6) Follow Through and Monitor

• Check-ins matter. If you’ve agreed on fortnightly catch-ups, hold them.
• Offer reasonable support and feedback during the improvement period.
• If performance doesn’t improve, escalate using your formal process, which may involve written warnings or a show cause letter.

Tip: Consistency is crucial. Apply this process across teams and roles (with sensible adjustments for different duties) to reduce claims of unfair treatment.

Common Pitfalls to Avoid

• Surprise feedback: if an issue is serious, don’t wait for the annual review to raise it. Address it promptly and document the discussion.
• Vague language: “improve your attitude” isn’t helpful. Use specific examples and define the expected standard.
• Inconsistency: applying a stricter standard to one employee than others doing similar work can look discriminatory.
• Retaliation risk: never link poor ratings to a complaint or a lawful absence. Keep performance assessments separate from protected activity.
• No paper trail: undocumented conversations are hard to rely on later. Write it down.

Documents and Policies That Help Protect Your Business

Strong documentation underpins fair reviews and defensible decisions. Consider whether you have the following in place and up to date.

• Employment Contract: sets out duties, responsibilities, performance expectations and how feedback is given (including review frequency if relevant).
• Workplace Policy: your staff handbook or policy suite should explain performance management steps, documentation, timelines and who is involved.
• Employee Privacy Handbook: clarifies how you handle personnel files, access to records and confidentiality of review materials.
• Show Cause Letter: used when you need an employee to respond to serious performance or conduct concerns before a decision is made.
• Employee Termination Documents Suite: templates and guidance to ensure warnings and dismissal documents are consistent and procedurally fair if performance ultimately doesn’t improve.
• Training and development plans: a simple template to outline support measures (e.g. coaching, training, buddying) and review points.

Having these documents correctly tailored to your business helps everyone understand the process from day one and reduces inconsistency.

Special Scenarios to Handle With Care

Probation Reviews

End-of-probation discussions are just as important. Keep them evidence-based, document feedback and make your decision clear. If you’re extending probation or ending employment, make sure your contract allows for it and that you follow your set process.

Health, Injury or Capacity Issues

If performance is affected by illness or injury, tread carefully. Focus on inherent job requirements and consider reasonable adjustments where appropriate. Document any medical information sensitively and in line with your privacy practices.

Remote and Hybrid Teams

Remote work can make observation and feedback harder. Adjust your criteria (for example, responsiveness, output metrics and collaboration behaviours), but keep the process consistent. Make time for video reviews and follow-ups to avoid miscommunication.

Small Businesses

If you have fewer than 15 employees, the Small Business Fair Dismissal Code may assist if a dispute arises - but it’s not a substitute for fairness. Clear warnings, reasonable opportunities to improve and basic documentation still matter a great deal.

Key Takeaways

• Performance reviews aren’t legally required under the NES, but they’re best practice and a key part of a defensible performance management framework.
• The Fair Work Commission assesses whether a dismissal for poor performance was harsh, unjust or unreasonable - clear notices, support and a genuine opportunity to improve are critical.
• Avoid legal risks by keeping reviews objective, consistent and free from discrimination, retaliation or bullying.
• Document review conversations, agreed action plans and follow-ups; store records securely and align them with your privacy settings and data retention approach.
• Support your process with solid foundations: an Employment Contract, clear Workplace Policy, privacy settings, and escalation tools like show cause letters where needed.
• If in doubt - especially where termination is on the table - get advice early to reduce the risk of disputes and ensure procedural fairness.
