Maximum Probation Periods in Australia

Bringing new people into your team is exciting, but the first few months are critical. A probation period lets you assess performance and fit, and gives your new hire a chance to decide whether the role is right for them.

In Australia, probation is common across most industries. However, there’s a lot of confusion about how long it should run, whether you can extend it, and what happens with notice and dismissals during this time.

This guide breaks down how probation works under Australian employment law, what “maximum” really means in practice, and how to manage the process fairly and legally. We’ll also walk through the key clauses to include in your contracts and the documents you should have in place from day one.

What Is a Probation Period?

A probation period is an initial trial phase at the start of employment. During probation, you monitor performance, conduct, and cultural fit. Your employee also uses this time to understand the role, expectations, and workplace standards.

Probation terms are set by agreement, usually in the Employment Contract. This is where you’ll confirm how long probation will run, what support and reviews you’ll provide, and how notice works if either party ends employment during probation. Most employers also outline clear performance objectives for the probation period to keep everyone on the same page.

Importantly, probation doesn’t remove an employee’s basic workplace protections. Even at this early stage, you must still comply with workplace laws, including anti-discrimination and general protections under the Fair Work framework.

How Long Can Probation Last in Australia?

There’s no statute that forces you to set a specific probation period. You can choose what’s appropriate for the role-as long as your approach remains consistent with Australia’s unfair dismissal rules.

Typical Practice vs Legal Effect

Most employers set probation at three or six months. That’s usually enough time to properly onboard, set expectations, review performance, and make a confident decision.

However, it’s a common misconception that there’s a strict “legal maximum” for probation itself. In reality, the key legal concept is the qualifying period for unfair dismissal eligibility. That qualifying period acts like a practical ceiling for the risk profile around ending employment:

Six months: For most employers, an employee becomes eligible to bring an unfair dismissal claim after six months of continuous service.
Twelve months: If you are a small business employer (fewer than 15 employees), the unfair dismissal qualifying period is twelve months.

Why does this matter? You can describe a longer contractual “probation” if you want, but once the qualifying period has passed, an employee’s unfair dismissal rights apply regardless of what your contract calls the period. After six months (or twelve for small business employers), any termination decision should be treated with the same care you’d apply to any permanent employee’s dismissal.

Does This Differ in Queensland?

No. Probation practices are consistent nationally because the unfair dismissal qualifying periods come from federal law and apply across states and territories. Queensland private sector employers follow the same six-month (or twelve-month for small business) framework as employers in other states.

Can You Extend Probation?

You can extend probation if your contract allows for it and the employee agrees. Many businesses extend from three to six months when they need more time for training or to assess performance metrics fairly.

Just keep in mind that extending probation doesn’t delay the unfair dismissal qualifying period. If the qualifying period has ended, the employee may be able to bring an unfair dismissal claim regardless of an “extended probation” label. When deciding whether to extend, weigh up timing, your documentation to date, and whether a reasonable performance improvement plan could be more effective.

How Probation Works Day To Day

What To Include In Your Contract

Your Employment Contract should explain probation in plain terms so there’s no confusion later. Employers commonly include:

The probation start date and intended end date
Performance expectations and how they’ll be assessed
Any training or support the business will provide during probation
How often reviews will happen and who conducts them
Notice requirements for ending employment during probation
What happens at the end: confirmation, extension (if available) or termination

Set this out clearly to create a fair, transparent process. Good documentation at the start often prevents disputes later.

Reviews, Feedback and Support

Probation should be active, not passive. Schedule regular check-ins and provide specific, constructive feedback. If performance is below expectations, explain what needs to change and support the employee with practical steps. Keep short file notes of each discussion.

Towards the end of probation, hold a formal review meeting and confirm the outcome in writing. If employment is confirmed, let the employee know and set goals for the next period. If you intend to extend probation (where allowed) or end employment, make sure your process and timing align with your contract and workplace laws.

Notice, Dismissal and Legal Risks During Probation

Notice Periods During Probation

Notice requirements come from a mix of the National Employment Standards (NES), any applicable modern award or enterprise agreement, and your contract. During the first year of service, the NES generally requires at least one week’s notice for termination by the employer (or payment in lieu of notice). Your contract can provide more than this minimum.

Employees typically give notice as set by the contract. If a modern award applies, it may also include specific notice terms that interact with your contract, so check both documents to make sure you’re compliant.

If you choose not to work through a notice period, you may opt for payment in lieu of notice-again, ensure this aligns with your contract and any applicable industrial instrument.

Do You Need a Reason To Dismiss During Probation?

Legally, you don’t need to deliver a lengthy justification to end employment during probation. That said, best practice is to provide a short, factual reason and to have documentation that supports your decision. Clear feedback throughout probation is the best foundation for a defensible outcome at the end.

Unfair Dismissal and General Protections

The main risk calculation during probation revolves around the unfair dismissal qualifying period. Before an employee reaches six months (or twelve months for a small business employer), they generally cannot bring an unfair dismissal claim.

However, general protections and anti-discrimination laws apply from day one. An employee can allege adverse action if you dismiss them because they exercised a workplace right (for example, making a complaint or taking leave). It’s also unlawful to dismiss someone for discriminatory reasons. This is why consistent process, accurate records and lawful decision-making are crucial-even during probation.

Modern Awards and Enterprise Agreements

Check if a modern award or enterprise agreement applies to your employee. Some instruments include extra requirements around probation, performance discussions, notice or consultation. Where an award applies, it will interact with your contract and the NES, and you should comply with all minimum standards that benefit the employee.

Practical Steps To Manage Probation Periods

1) Choose a Sensible Probation Length

For most roles, three to six months is appropriate. If you’re a small business employer and you’re considering a longer period, make sure you have a clear operational reason. More important than the label is the timing of the unfair dismissal qualifying period and whether your internal process will be completed in time.

2) Lock In a Clear Contract

Use a well-drafted Employment Contract tailored to the role and any applicable award. Confirm the probation period, expectations, notice and what happens at the end of the period. If you offer an extension option, explain when and how it may be used.

3) Onboard Properly

Probation outcomes improve when onboarding is structured. Provide a position description, training, a plan for the first few weeks and scheduled check-ins. Be explicit about performance standards and company values from day one.

4) Review Early and Often

Give regular feedback so there are no surprises at the end. If performance or conduct issues arise, address them promptly and in writing. Where appropriate, use a short improvement plan to set clear targets and timelines during the probation period.

5) Make Timely Decisions

Don’t let the qualifying period lapse while you’re still undecided. Ensure final reviews and any decisions to end employment occur with enough time to manage notice or payment in lieu, handover of duties and return of property.

6) Document Everything

Keep records of induction, training, check-ins, feedback and any warnings. Objective documentation helps demonstrate that your decision was fair and based on genuine operational reasons or performance concerns.

What Documents Should Employers Prepare?

Having the right documents in place from the outset makes probation smoother and reduces risk. Consider the following:

Employment Contract: Sets out terms including probation, duties, pay, hours, notice and the interaction with any applicable award or enterprise agreement.
Workplace Policies: Clear policies on conduct, leave, performance and grievance handling help you set expectations and apply consistent processes.
Probation Review Template: A simple template keeps reviews consistent, prompts balanced feedback and captures agreed next steps.
Confirmation or Termination Letter: Written confirmation of the outcome at the end of probation ensures a clear record.
Privacy and Data Handling Documents: If the Privacy Act applies to your business, a Privacy Policy and appropriate internal procedures help you handle personal information lawfully.

On privacy, note that not every business is covered by the Privacy Act. Many small businesses under the $3 million turnover threshold are exempt, and there’s also an employee records exemption for private sector employers relating to employee records. That said, if you do handle personal information (for example, applicants’ details), it’s still wise to manage it transparently and securely-even where a formal policy isn’t strictly required.

Key Takeaways

There isn’t a strict statutory “maximum” probation period, but the unfair dismissal qualifying period (six months for most employers, twelve months for small business employers) is the practical legal marker to keep in mind.
Probation terms should be clearly set in your contract, including the period, performance expectations, reviews, and notice requirements for both sides.
Provide regular feedback and support during probation. Good documentation and timely reviews make end-of-probation decisions more straightforward and defensible.
Even during probation, general protections and anti-discrimination laws apply from day one. Always ensure your decisions are lawful and based on objective reasons.
Check any applicable modern award or enterprise agreement for extra requirements that interact with your contract and the NES.
Put core documents in place early-contracts, policies, review templates and clear outcome letters-and assess whether privacy obligations apply to your business.
