Defence Hub › Limitation Periods
If you’re reading this, there’s a good chance you’re worried the window has already closed. Before you walk away from a potential claim, read this page. The rules around limitation periods are more nuanced than most people realise — and in many cases, the clock hasn’t started when you think it has.
If you’re reading this page, there’s a good chance you’re worried time has already run out. Maybe someone told you that you only had three years, and those three years passed. Maybe you’ve only just realised — after speaking to another professional, or after things got considerably worse — that the advice or treatment you received years ago was the problem all along.
Before you walk away from a potential claim, read this page. The rules around limitation periods are more nuanced than most people realise. A fixed clock does not always start ticking on the day something went wrong. In many cases, the law does not begin counting time until you actually knew — or reasonably should have known — that you were harmed by a professional’s failure.
At Fair Go Australia, our specialist professional negligence lawyers assess limitation period questions as part of every free case evaluation. If there is a pathway available to you, we will find it.
A limitation period is the window of time within which a person must commence legal proceedings. If a claim is not filed within that window, the right to pursue it may be permanently lost — regardless of how strong the underlying case might have been. Limitation periods are set by legislation, vary between states, and can in some circumstances be extended or postponed.
Limitation periods exist to protect defendants from having to defend claims about events that occurred so long ago that evidence has been lost or memories have faded. They are set by legislation, not by courts, and they vary between states and between different types of claims.
Importantly, missing a limitation period does not automatically end every option. Courts retain limited discretion to extend time in specific circumstances, and the period itself may not have started when you assume it did.
This is the part that most people get wrong — and it matters enormously.
Many people assume that the limitation period starts on the date the professional did something wrong. In practice, the law in every Australian state and territory recognises what is known as the discovery rule: time generally runs from the date you knew, or ought reasonably to have known, that you had suffered harm as a result of the professional’s conduct.
This distinction can be the difference between a live claim and a lost one.
Medical Negligence
The misdiagnosis that took years to surface
A GP dismisses concerning symptoms in 2018. You are eventually diagnosed with a serious condition in 2022, when a specialist identifies the missed signs from years earlier. Under the discovery rule, your limitation period may not have started until 2022 — when you first became aware that the earlier clinical failure caused your harm.
Solicitor Negligence
The file you never reviewed
Your property settlement was finalised in 2019. It is only in 2024, when a new solicitor reviews the documents, that you discover your former lawyer failed to identify a binding financial agreement that significantly affected the outcome. The limitation period may run from 2024, not from 2019.
Financial Advice Negligence
The loss that compounded in silence
A financial adviser placed you in unsuitable investments in 2017. The investments performed adequately for several years before collapsing in 2022. You discover the original advice was deficient when an accountant reviews your portfolio. The clock may have started in 2022, not 2017.
Case Law Reference
Courts apply an objective standard: not when you subjectively became aware, but when a reasonable person in your position would have discovered the harm. The High Court’s decision in Hawkins v Clayton (1988) 164 CLR 539 established foundational principles on the discoverability of professional negligence and continues to inform how Australian courts assess when time begins to run.
Limitation periods are set by state and territory legislation. Getting this wrong — or applying the wrong state’s rules to your claim — can have serious consequences. The table below provides a national overview.
| State / Territory | Primary Legislation | General Period | Personal Injury | Discovery Rule |
|---|---|---|---|---|
| NSW | Limitation Act 1969 (NSW) | 6 years | 3 years | Yes |
| VIC | Limitation of Actions Act 1958 (VIC) | 6 years | 3 years | Yes |
| QLD | Limitation of Actions Act 1974 (QLD) | 6 years | 3 years from discovery | Yes |
| WA | Limitation Act 2005 (WA) | 6 years | 3 years | Yes |
| SA | Limitation of Actions Act 1936 (SA) | 6 years | 3 years from discovery | Yes |
| TAS | Limitation Act 1974 (TAS) | 6 years | 3 years | Yes |
| ACT | Limitation Act 1985 (ACT) | 6 years | 3 years from discovery | Yes |
| NT | Limitation Act 1981 (NT) | 6 years | 3 years from discovery | Yes |
Which limitation period applies to your claim depends on the state where the professional was engaged, the nature of the harm, and the date the cause of action arose. These are not always straightforward questions — a professional negligence lawyer should confirm which legislation governs your situation before any decision is made about whether to proceed.
In some circumstances, yes — and this is why it is worth speaking to a lawyer before assuming your claim has expired.
Fraud or deliberate concealment
Where a defendant has deliberately concealed their negligence — destroyed records, provided false explanations, or actively misled you about what happened — courts may postpone the start of the limitation period until the concealment was or should have been discovered.
Legal disability
If a claimant was under a legal disability at the time the cause of action arose — for example, a minor, or a person lacking mental capacity — the limitation period is generally suspended until the disability ceases. This applies across all Australian jurisdictions, though specific rules vary.
Court discretion to extend time
Some states allow courts to grant extensions in appropriate circumstances. This is not a routine remedy. Courts will consider the reason for delay, the length of the delay, and any prejudice to the defendant. Where there are genuine grounds, it remains a real option.
Acknowledgement of liability
In some circumstances, an acknowledgement of liability by the professional, their employer, or their insurer — even an informal one — can reset or pause the limitation period under the relevant state Act. This is a technically specific area that requires careful legal assessment.
Latent damage and delayed discoverability
Where the damage caused by the negligence was not capable of being discovered at the time of the negligent act, most Australian jurisdictions extend the limitation period beyond what the standard calendar calculation would suggest. This is particularly relevant in medical negligence claims involving progressive or slowly developing conditions.
Whether any of these mechanisms applies to your situation is a question that requires proper legal assessment. If you are uncertain whether your limitation period has passed, do not assume it has — speak to a specialist first.
Important Notice
Act before time runs out
In Australia, professional negligence claims must generally be commenced within 3 to 6 years of the date you became aware — or should reasonably have become aware — of the negligence and the harm it caused. Limitation periods vary by state and claim type. Missing this deadline can permanently extinguish your right to claim.
If you are unsure whether your limitation period is still open, contact our team for a free assessment as soon as possible.
When a defendant raises a limitation period as a defence, it becomes a threshold issue — one the court must determine before it will even consider the merits of the claim. This means a case that might have been strong on the facts can be struck out without the substance ever being heard.
Defendants and their insurers are well aware of limitation periods. Legal teams representing professionals will routinely scrutinise the timeline of events early in any claim, looking for grounds to argue the claim is statute-barred. This is not a technicality they will overlook.
This is why claimants should never treat the limitation deadline as a target. Evidence must be gathered, expert reports obtained, and often a letter of demand sent before proceedings are commenced. All of that takes time. Starting the process six months before the deadline is risky; starting it weeks before is far more so.
Even where a client is close to the limitation period, it may be appropriate to commence proceedings to preserve the right to claim while negotiations or investigations continue. A specialist professional negligence lawyer can advise on whether this is the right course of action for your situation.
Many people walk away from legitimate claims because they assume the limitation period has closed. In a significant number of cases, it has not — because of the discovery rule, delayed discoverability, or because an extension mechanism applies. Before you make that assumption, let our specialist team review your situation. A free case evaluation costs you nothing.

It depends on your state and the nature of the harm. For most professional negligence claims, the limitation period is either three or six years. Personal injury claims — including many medical negligence claims — generally carry a three-year limitation period running from the date of discovery. Pure economic loss claims, such as those arising from negligent legal or financial advice, often carry a six-year period, though this also varies by state. The key point is that time generally runs from when you discovered the harm — not necessarily when the negligent act occurred.
Not necessarily. The discovery rule is central to professional negligence law in Australia. If you could not reasonably have known about the negligence at the time it occurred — because the harm was latent, the records were unavailable, or the connection only became clear recently — your limitation period may not have started until that point of discovery. This is precisely the kind of question a specialist lawyer should assess. Do not make that determination yourself.
In some states and in limited circumstances, yes. This varies significantly by jurisdiction and is not a routine outcome. Courts will weigh the reason for the delay, the length of time elapsed, and whether the defendant would be materially prejudiced. It is available in appropriate cases — but it should never be relied upon as a substitute for acting promptly.
The same legislative framework generally applies to both, but the critical difference lies in when the period starts. Medical negligence often involves latent harm — a condition that deteriorates over years, or a misdiagnosis whose consequences only become apparent later. This can push the discovery date well beyond the date of the original clinical event. Solicitor negligence often becomes apparent only when a separate legal review is carried out, or when the consequences of the original error materialise in subsequent proceedings or transactions.
If proceedings are commenced after the limitation period has expired, the defendant can apply to have the claim struck out. Courts will not ordinarily hear the merits of a claim that is statute-barred. However, there are exceptions — including fraud, concealment, disability, and in some states a judicial discretion to extend time. Before concluding that your claim has expired, have it assessed by a professional negligence lawyer. The analysis is more nuanced than a simple date calculation.
