Time limits for a silicosis claim in Australia

You were diagnosed with silicosis three months ago. Or six months ago. Or maybe years ago.

The question now is whether there is still time to make a claim.

The answer depends on where you worked, what type of compensation you are pursuing, and exactly when the clock started ticking. There is no single Australia-wide deadline that applies to every silicosis claim. The time limit that matters for you depends on the state or territory where the exposure happened, whether you are making a statutory workers’ compensation claim or a common law damages claim, and when you knew (or should have known) you had a silica-related condition.

This article walks you through the different deadlines, explains when the clock starts, shows you what to check right now, and tells you what to do if you think you might have missed a deadline.

One condition, a different deadline in each state

Silicosis is a single disease, but the time limit to make a claim is not written in stone across Australia. You might be entitled to statutory workers’ compensation benefits under one set of rules and common law damages under a different set of rules, each with its own time requirement.

Most people assume the deadline starts when they were exposed to silica. It may not.

The clock usually starts when you are diagnosed, or when you know (or reasonably should know) that you have a silica related condition. That distinction matters, because silicosis can take 10, 20, or even 30 years to develop after exposure. The latency period means you can be well outside any exposure window and still have a live claim, as long as you act promptly after diagnosis.

The danger is this: you receive a diagnosis, you feel overwhelmed, you wait to see if symptoms improve, and by the time you decide to pursue compensation, a key deadline has passed.

Key Point

The time limit is not a hypothetical legal technicality. Miss it, and you can lose the right to compensation entirely, no matter how strong your medical evidence or how obvious your employer’s failure to protect you.

When does the clock usually start

In most Australian jurisdictions, the relevant starting date for a silicosis compensation claim is tied to diagnosis or knowledge, not exposure.

Diagnosis means the date a qualified medical practitioner formally identifies that you have silicosis or another silica-related condition. This might be confirmed by a CT scan, a respiratory function test, a specialist report, or a combination of investigations. If you are not certain which dust related condition you have been diagnosed with, the difference between silicosis and asbestosis sets out how the two are told apart. The date of the first scan is not always the date of diagnosis; diagnosis requires a medical opinion that connects the imaging or test results to a silica-related disease.

Knowledge (sometimes called the “date of discoverability”) is a broader concept. It means the date on which you knew, or reasonably should have known, that:

• You had a condition (not just symptoms)
• The condition was caused or contributed to by your work
• The condition was significant enough to warrant a compensation claim

You do not need a formal diagnosis to have “knowledge” for limitation purposes. If a doctor tells you in plain terms that your lung condition is linked to silica exposure at work, the clock may start running even if the final written report arrives weeks later.

Why does this matter?

Because some people hear “six months from diagnosis” and think the diagnosis date is the date the specialist report was typed. In reality, the legally relevant date may be earlier: the day the doctor explained the diagnosis to you, or the day you received a letter setting out the conclusion.

If you are told in a consultation that your scan shows silicosis, that conversation can mark the start of the limitation period, not the date the formal report was issued.

Expert Tip

Write down the date of every medical consultation, scan, and report. If a doctor mentions silicosis or a silica-related condition, ask for the conversation to be documented in writing and keep a copy. That documentation may become critical if a deadline is disputed later.

Statutory workers’ compensation deadlines for silicosis

Every state and territory runs a statutory workers’ compensation scheme, and every one of them wants the claim lodged quickly. These are the deadlines that catch people out, because they are measured in months while the court deadlines are measured in years.

Queensland and the Northern Territory are the clearest. In both, a worker must generally make a statutory claim within six months from the date of a relevant medical assessment or diagnosis.

South Australia and Tasmania are generally six months as well. Western Australia allows generally twelve months from discovering the condition, and the ACT asks for the claim as soon as practicable and within three years. Victoria asks for it promptly, and weekly payments can be cut back where it was not. New South Wales is the exception: a dust disease claim there goes to icare Dust Diseases Care, which has no lodgement deadline.

A deadline measured in months is not a suggestion. It is a statutory requirement, and it is the one that most often decides whether a worker is paid while the rest of the claim is argued about.

These deadlines apply to claims for weekly compensation, medical expenses, rehabilitation, and lump sum payments for permanent impairment. The general process is the same as any other workers’ compensation claim; the deadline is what differs in practice, because diagnosis rather than an accident is what starts it.

What counts as the starting date?

The wording in legislation differs, but it usually refers to words to the effect of “relevant medical assessment”, which typically means the date a doctor formally diagnoses the condition or provides a written opinion that the worker has a compensable silica-related disease. It is not the date symptoms first appeared, the date the worker stopped working, or the date the worker decided to make a claim.

What happens if you apply after the deadline?

The scheme insurer is not required to accept a late application. In Queensland, WorkCover (or the employer’s insurer) has a discretion to accept a claim outside the six-month period if the worker can show a reasonable excuse for the delay, mistake or absence from the State, and the other schemes have their own versions of that discretion.

“Reasonable excuse” is not defined exhaustively, but examples might include:

• The worker was seriously ill and unable to make a claim
• The worker was not told about the diagnosis until after the six-month period
• The worker was given incorrect advice by a medical practitioner or other professional
• The worker did not understand the nature or seriousness of the condition within the six months

Acceptance of a late claim is discretionary everywhere. If the application is refused, the worker’s only remedy is usually to seek a review of that decision, which itself has strict time limits.

The practical reality: whichever state you worked in, treat the statutory deadline as hard. Do not rely on an extension. Do not wait for further tests. Lodge the claim and supplement it afterwards.

Key Point

A statutory deadline is not the same as a court deadline, and missing one does not necessarily cost you the other. Queensland’s six months is the statutory clock. Queensland’s court clock, for a dust-related condition, does not run at all.

What if the deadline has already passed

You open this article seven months after diagnosis. Or 12 months. Or longer.

Does that mean your claim is over?

Not necessarily, but the position needs checking rather than waiting out.

First step: get advice on your limitation position before gathering anything else. People often hold off until they have “all the information”, and the information rarely changes the answer, while the date does.

Second step: document why the delay occurred. Did you not receive the diagnosis report until months after the scan? Were you too unwell to engage with the process? Did a doctor or another adviser give you incorrect information about the deadline? Write it down, and keep any supporting documents (letters, emails, medical records, file notes).

Third step: if you have not yet lodged a workers’ compensation claim, lodge it now with a detailed explanation of the reason for delay. Do not assume the insurer will reject it; sometimes a late application is accepted without issue, especially if the reason for delay is clear and the claim is otherwise straightforward.

Fourth step: even if the statutory workers’ compensation claim is refused or partially refused, you may still have other compensation pathways available. A court claim for damages runs on a different clock, and in Queensland, Victoria, New South Wales and the Northern Territory that clock may not be running at all (discussed below).

The key is this: a late diagnosis is not the same as a lost claim. It makes the claim more complicated, and it may reduce the compensation available, but it does not automatically mean you have no entitlements.

Expert Tip

If your workers’ compensation claim is rejected because it was lodged too late, you generally have a limited window to seek an internal review or take the decision to the scheme’s tribunal, which in Queensland is the Industrial Relations Commission. Get advice as soon as you receive the rejection notice, not weeks later.

Common law compensation claims for silicosis

A workers’ compensation claim is a statutory entitlement: weekly payments, medical expenses, rehabilitation, and a possible lump sum for permanent impairment. It is governed by the Workers’ Compensation and Rehabilitation Act 2003 (Qld) and similar legislation in other states.

A common law claim is different. It is a damages claim for negligence, alleging that your employer (or another party) breached a duty of care and that breach caused your silicosis. Common law damages can include compensation for past and future economic loss, past and future medical treatment, home care, loss of superannuation, and general damages for pain, suffering, and loss of enjoyment of life.

In four places, there is no deadline on a court claim for a dust-related condition at all. Queensland removed it, and a court claim for a dust-related condition can be brought at any time. New South Wales has no limitation period in its Dust Diseases Tribunal. Victoria has none for a dust-related condition. The Northern Territory has none either.

That is not a loophole or an argument you have to run. It is what the limitation legislation in those places says, and it exists because the law accepted long ago that a disease which appears twenty or thirty years after the dust was breathed cannot sensibly be governed by an ordinary deadline.

In the other four, a period of about three years applies. Western Australia and South Australia generally run three years from the cause of action accruing. Tasmania runs three years from when the disease was discoverable. The ACT runs three years from when you knew you had the condition and that it was connected to someone else’s conduct.

Where a period does apply, what may not matter is the start date of exposure or the duration of exposure, or when you first had symptoms. What may be relevant and important is, for example, when you could connect your diagnosis to your employer’s failure to provide ventilation or respiratory protection or when a lawyer explains the link to you.

The takeaway: a court claim almost always has a longer runway than the statutory claim, and in half the country it has no deadline at all. That is not a reason to wait, for reasons the next section explains.

How the rules differ across Australia

Australia does not have a uniform silicosis compensation scheme. Each state and territory has its own workers’ compensation legislation, its own common law framework, and its own rules about time limits and late claims.

Treat every figure in that table as the starting point for a check, not the answer. The deadline that applies to you may depend on where the employment was, which scheme covers it, and when your date of knowledge fell.

The practical point: do not assume that a deadline you read about in a Queensland context applies to your claim if you currently live in Queensland but worked in another state. Check the rules that apply to your specific circumstances.

Expert Tip

If you worked for the same employer in multiple states, or worked for different employers in different states, your claim may involve more than one jurisdiction. Seek advice from our lawyers who are experienced in multi-state compensation claims, because the entitlements to compensation can differ significantly.

What to do after a silicosis diagnosis

You have been told you have silicosis, or a suspected silica-related condition. What should you do first?

Step one: obtain and keep copies of every medical record, scan, test result, specialist report, GP letter, and hospital discharge summary related to your diagnosis. Do not rely on your doctor or specialist to keep these records indefinitely. Request copies and store them securely. If you have imaging (CT scans, X-rays), ask for a copy on disc or USB.

Step two: write down a complete employment history: every employer you worked for where you were exposed to silica dust, the dates you worked there, the location of the worksite, the tasks you performed (cutting, grinding, drilling, polishing, dry sweeping), the materials you worked with (engineered stone, natural stone, concrete, bricks, tiles, pavers), and the protective equipment you were (or were not) provided. Include the names of supervisors, co-workers, and labour-hire companies if you worked through an agency.

Step three: identify the date you were diagnosed. If possible, get a letter from your doctor stating the date they diagnosed silicosis or told you that you had a silica-related condition. This letter may become critical if the insurer disputes when the limitation period started.

If you are still employed and have not yet told your employer, how long you have to report a workplace incident covers what a proper report looks like.

Step four: notify your employer (or former employer) in writing that you have been diagnosed with silicosis and that you believe it was caused by exposure to silica dust at work. Keep a copy of the letter and proof of delivery. Do this even if you are no longer employed by that employer. Notification is not the same as making a formal claim, but it is an important step.

Step five: check the applicable time limit for the state or territory where you worked. Lodge promptly and within the time limit. Sometimes lodging outside of the time limit may mean that you miss out on claiming compensation forever.

Step six: seek legal advice now, not later. You do not need to wait until you have “all the information” or until your condition stabilises. A lawyer can help you lodge the workers’ compensation claim within the deadline, preserve evidence, notify all relevant parties, and assess whether you have a common law claim as well.

If a family member has died

Silicosis can progress rapidly, especially in cases of acute or accelerated disease. If your family member was diagnosed with silicosis and has since died, you may have a right to bring a claim on behalf of the estate or as a dependant.

Estate claims are brought by the executor or administrator of the deceased’s estate and seek compensation for the losses suffered by the deceased before death (medical expenses, pain and suffering, lost income up to the date of death). The time limit for an estate claim usually follows whatever would have applied to the deceased, so in the places with no limitation period for a dust-related condition there may be none here either. Elsewhere it may run from the date of death or the date of knowledge, depending on the jurisdiction and the type of claim.

Dependency claims are brought by a spouse, de facto partner, child, or other dependant who suffered financial or other loss as a result of the death. These claims are sometimes called “wrongful death” or “nervous shock” claims, and they are governed by separate limitation rules in each state.

If your family member died without making a workers’ compensation claim or a common law claim, it is worth getting advice on where the time limits sit. The periods for death related claims can be short, and the procedural requirements are complex.

Do not assume that because the deceased never made a claim, the right to compensation has been lost. Estate and dependency claims are separate causes of action, and they may still be available even if the deceased did not pursue compensation during their lifetime.

Expert Tip

If a death certificate lists silicosis or a silica-related condition as a cause of death, obtain a copy and keep it with the deceased’s medical records. You will need it to support an estate or dependency claim.

What happens when a claim is lodged late

What does “late” actually mean in practice?

If you lodge a Queensland claim seven months after diagnosis instead of six, the insurer may accept it without question, especially if the delay was short and the claim is straightforward. Late claims are not always accepted, and in fact they are often rejected, even if the worker believes that they have a reasonable explanation for the delay.

The insurer is not required to accept a late claim. If the delay is longer, or if the insurer disputes causation or liability, the insurer may refuse the claim on the basis that it was lodged outside the statutory time limit. At that point, you will need to apply for an extension or a waiver, which requires you to prove a reasonable excuse and may involve a hearing before the scheme’s tribunal.

That process takes time, costs money, and introduces uncertainty. You may win, but you may not. And even if you do win, you have added months to the claim process and increased the stress and expense.

The same principle applies to a court claim, in the states where a period applies.

Key Point

A lawyer cannot guarantee that a late claim will be accepted or that a court will extend the limitation period. The best strategy is to lodge your claim on time, not to rely on an extension that may or may not be granted.

Which state’s time limit applies if you worked in more than one

You worked in Queensland for two years and New South Wales for five years, cutting and installing engineered stone benchtops. You were diagnosed with silicosis in Victoria, where you now live.

Which state’s time limits apply?

The answer depends on where you were employed when the exposure occurred, which state’s workers’ compensation scheme covers the employment, and where you choose (or are required) to bring a common law claim.

Workers’ compensation claims are generally brought in the state or territory where the employment took place, and the time limits of that state apply. If you worked in multiple states, there may be a complex analysis that needs to be done to identify the correct law that applies.

Common law claims can sometimes be brought in more than one state. Generally speaking, the time limits of the state where the exposure occurred will usually apply (subject to complex conflict-of-laws rules that depend on where the negligence occurred, where the harm was suffered, and where the parties are located) and it is often not a straightforward matter.

This is not something you should try to navigate alone. Multi-state claims require careful legal advice to ensure that you lodge your claim in the right place, within the right time limit, and against the right defendants.

Expert Tip

If you worked for a national employer or a labour-hire company that operated in multiple states, keep records showing which state you worked in on which dates. The insurer will ask for this information, and it may affect which state’s time limits apply.

What to do once you have a diagnosis date

You have been told you have silicosis. You read this article. You understand that time limits exist and that they may be short.

What do you do?

Speak to a lawyer who acts in silicosis and silica related disease claims. Not a general practice firm. The time limits differ by state and by claim type, and the person reviewing your position needs to have worked through them before.

Most compensation lawyers, including Rogalski Lawyers, act on a no win, no fee* basis, which means no legal fees unless the claim succeeds. Rogalski Lawyers offers a free case review.

Ask for a review of your position before you have everything. You do not need to wait until you have “all the documents” or until your condition stabilises. The lawyer can help you gather the documents and can lodge a holding claim if necessary to preserve your rights while the full claim is prepared.

Bring whatever you have: diagnosis letters, scan reports, employment history, payslips, and any correspondence with the employer or insurer. If you do not have these documents yet, say so. The lawyer can help you obtain them.

Ask the lawyer to check the applicable time limits for your specific circumstances. Do not assume that what you have read online (including in this article) applies to your case. Every claim is different, and the time limits depend on facts that only you and your lawyer can verify together.

Lodge the claim within the deadline. Once the lawyer confirms the deadline, treat it as absolute.

Silicosis is a preventable disease. Where it was caused by exposure at work, the compensation schemes exist to deal with that, and the time limits are the window in which they can be used. The window is what closes, not the facts of what happened to you.

Expert Tip

When you contact a lawyer, have the diagnosis date ready to provide with your history of silica exposure.
