You may be wondering what happens when an old injury flares up again at work. Maybe your back pain that started years ago has suddenly worsened after a shift of heavy lifting. Or perhaps a past shoulder issue was aggravated by repetitive tasks on the job. If this sounds familiar, you’re not alone, and you may be asking a very important question: Can I claim workers compensation for an aggravation of a pre-existing condition?
In New South Wales, many workers are surprised to discover they may still be entitled to workers compensation, even if their injury wasn’t entirely new. When your job worsens a pre-existing condition, the law may still recognise it as a valid workers compensation claim. But here’s the catch: success depends on proving that your work mainly contributed to the aggravation of the condition.
This is where most claims are won or lost. And this is exactly where Withstand Lawyers can help.
Our experienced workers compensation team knows the ins and outs of dealing with aggravated injury claims. We understand the frustration of living with a condition that’s been made worse by your job, and we know how to build a strong case backed by clear medical evidence. If you’re feeling uncertain or overwhelmed, you’re in the right place.
Read on to see how we’re here to help you move forward with clarity and confidence after aggravating a pre-existing injury at work.
What Is a Pre-Existing Condition in Workers Compensation Claims?
A pre-existing condition is any health issue or injury you had before your current employment or before the incident you’re claiming for. In workers compensation claims, this can include injuries from previous jobs, sports accidents, past surgeries, or even chronic conditions like arthritis.
What many workers don’t realise is that having a pre-existing condition doesn’t automatically disqualify you from receiving compensation. The law in NSW recognises that work can worsen or aggravate a pre-existing condition, and when that happens, you may have a legitimate right to claim.
Common Examples of Pre-Existing Conditions
Some of the most common pre-existing conditions that lead to successful workers compensation claims when aggravated at work include:
Lower back pain or disc injuries that worsen after heavy lifting, awkward or prolonged activities
Knee injuries that flare up due to repetitive squatting, lifting, sitting or standing
Shoulder or rotator cuff damage made worse by overhead tasks
Arthritis or joint degeneration accelerated by physical labour
Repetitive strain injuries (RSI) from years of computer work or factory tasks
Mental health conditions, like anxiety disorders or depression, triggered again by workplace stress
Whether your condition stems from an old workplace injury or a non-work-related issue, you may still be entitled to make a claim. Contact our experienced workers compensation lawyers today to find out if your aggravated injury is eligible for a workers compensation claim. We offer a free claim assessment, and can manage your claim on a No Win No Fee basis.
Difference Between New Injuries and Aggravated Injuries
Understanding the difference between a new injury and an aggravated pre-existing condition is critical, especially when it comes to getting your claim approved.
A new injury is one that occurs for the first time at work, such as tearing a ligament or breaking a bone. An aggravated injury, on the other hand, is when a previous condition had stabilised or caused no ongoing issues is made significantly worse by your work duties.
For example:
If you injured your back five years ago but recovered, and now your current job has caused the pain to return or worsen, that’s likely an aggravation.
If your shoulder had mild pain but it suddenly became worse after work, that could also be considered an aggravation.
In both cases, the worsening must be clearly linked to your work duties. This is why medical evidence, timelines, and legal guidance are essential. At Withstand Lawyers, we help clients gather the right information to clearly show how work has aggravated their condition, giving you the best possible chance of success.

Can You Claim Workers Compensation for an Aggravated Pre-Existing Injury in NSW?
Yes, you can claim workers compensation for a pre-existing injury, provided you can show that your work has aggravated a pre-existing condition. In New South Wales, the workers compensation system allows claims for aggravated injuries as long as your employment was a substantial (if it was an incident) or main (if it progressed over time) contributing factor to the worsening of your condition.
It’s not enough for the injury to simply exist. Your claim must prove that your current job duties contributed to the deterioration. This can be particularly challenging when insurers argue that your symptoms are part of a natural progression or unrelated to work. That’s where legal guidance becomes essential.

NSW Workers Compensation Law on Aggravation of Existing Conditions
Under the Workers Compensation Act 1987 (NSW), you may be entitled to compensation if your employment aggravated, accelerated, exacerbated, or deteriorated a pre-existing injury or medical condition.
This legal framework recognises that injuries aren’t always new, and that work can make an old injury worse. Even if your condition existed before starting your current role, or even before entering the workforce, you may still qualify for workers compensation in NSW if your job played a substantial part in aggravating it.
At Withstand Lawyers, we regularly help injured workers meet this legal threshold. We work with independent doctors, specialists, and other experts to gather strong medical evidence and prove that your work has directly contributed to your current condition.
Your Employer’s Liability for Worsening a Pre-Existing Injury
Employers in NSW have a clear legal obligation to provide a safe working environment, and that includes considering any known pre-existing conditions that staff may have.
If your employer was aware (or reasonably should have been aware) of your condition and failed to take appropriate steps to minimise risk, such as adjusting duties, offering alternative tasks, or providing proper ergonomic equipment, they may be found responsible for any further harm.
That said, it’s important to remember that NSW operates under a no-fault workers compensation scheme, meaning you do not need to prove your employer was negligent. Your claim can still succeed even if your employer wasn’t aware of your condition. What matters is whether your work objectively contributed to the aggravation.
If your claim is successful, you may be entitled to:
Weekly payments for lost income
Medical and rehabilitation expenses
Lump sum compensation for permanent impairment
In some cases however, the situation may go beyond a standard workers compensation claim. If your employer’s negligence directly caused the worsening of your pre-existing condition, you may also have grounds to make a work injury damages claim (also known as a common law claim). This type of claim provides a lump sum payout for past and future economic loss.
Common Scenarios of Pre-Existing Injuries Worsened at Work
Many workers in NSW continue to perform their duties despite having old injuries or chronic conditions. Unfortunately, the physical and mental demands of certain jobs can easily cause these pre-existing conditions to deteriorate. Below are some of the most common scenarios that we’ve seen where injuries that already existed become significantly worse due to work, often leading to valid workers compensation claims.
Back Injuries
Lower back pain and spinal injuries are among the most frequently aggravated conditions in the workplace. Whether your initial injury occurred years ago from heavy lifting, a car accident, or a sporting mishap, physically demanding roles can cause a relapse or worsening of symptoms.
Common work activities that aggravate back injuries include:
Repetitive bending or twisting
Lifting heavy objects
Prolonged sitting or standing
Driving for extended periods
Even if your back issue had stabilised, a sudden increase in workload or change in tasks can trigger a flare-up. If your current job duties caused this deterioration, you may be entitled to workers compensation in NSW.
Knee or Shoulder Problems
Knee injury claims and shoulder injury claims are common across many physical occupations. Joints like the knees and shoulders are highly vulnerable to aggravation of pre-existing injuries, particularly in jobs that require lifting, kneeling, climbing ladders, or overhead work.
For example:
An old ACL or meniscus injury might worsen from constant squatting or stair climbing on a construction site.
A previous rotator cuff tear could be aggravated by repeated lifting or reaching tasks in a warehouse or factory setting.
Even mild joint issues can become disabling if the demands of your job go unaddressed. The NSW workers compensation scheme recognises this, and a claim may be possible if your work has caused the condition to deteriorate.
Repetitive Strain Injuries (RSI)
RSI and overuse injuries are especially common in office workers, factory employees, retail staff, and healthcare professionals. These injuries often start as manageable discomfort but can escalate into chronic pain and loss of function if aggravated by repetitive tasks.
Common examples include:
Wrist or forearm pain from prolonged typing or use of handheld scanners
Tendonitis or bursitis from repeated manual tasks in cleaning, nursing, or manufacturing roles
Neck injuries and shoulder tension due to poor ergonomic setups or sustained posture
If your job has made an existing RSI worse, suddenly or gradually over time, you may have grounds for a workers compensation claim. Documenting symptoms early and seeking legal advice can greatly improve your chances of success.
If you’re unsure if your aggravation of a pre-existing condition qualifies, contact our experienced team of workers compensation lawyers today. We offer a free claim assessment with clear, personalised advice and can act on your behalf on a No Win No Fee basis, meaning you’ll never pay out of pocket to make a claim.
What Compensation Can You Claim for an Aggravated Injury?
If your work has caused a pre-existing condition to worsen, you may be entitled to several types of compensation under the NSW workers compensation scheme. The goal is to help you recover financially, physically, and emotionally — without needing to prove fault or negligence. Below are the main entitlements you may be eligible to claim.
✅Weekly Payments
Weekly compensation is designed to cover lost income if your aggravated injury prevents you from working or reduces your ability to earn. In NSW, the amount and duration of payments depend on both the severity of your injury and your work capacity.
Here’s how it generally works:
First 13 weeks: You can receive up to 95% of your pre-injury average weekly earnings (PIAWE). If you have some work capacity, the amount may be reduced by what you are currently earning.
Weeks 14 to 260: You can receive up to 80% if you are unable to return to work, or up to 95% if you are able to work 15 hours or more each week.
Beyond 260 weeks: Weekly payments can only continue if you are assessed with a Whole Person Impairment (WPI) of more than 20%. In these cases, you may continue to receive weekly payments until retirement.
✅Medical Expenses
If your pre-existing condition has been worsened by your job, your employer’s workers compensation insurer is generally responsible for covering reasonable and necessary medical treatment related to the aggravated injury.
This can include:
GP and specialist consultations
Diagnostic scans and medical imaging
Physiotherapy, chiropractic, or psychological therapy
Medication and pain management
Surgery and post-operative care
Travel costs to and from medical appointments
✅Lump Sum Compensation for Permanent Impairment
If your aggravated pre-existing injury results in a permanent impairment, whether physical or psychological, you may be entitled to a lump sum compensation payment. In some cases, you may also have the right to make a separate work injury damages claim (also known as a common law claim) if negligence was involved.
Your eligibility to claim lump sum compensation is determined by a Whole Person Impairment (WPI) assessment, usually carried out at least six months after your injury has stabilised. An Independent Medical Examiner (IME) will assess the long-term impact of your aggravated injury and assign a WPI rating.
To qualify for a lump sum compensation payment in NSW:
Physical injuries must meet a minimum 11% WPI threshold (or 1% WPI if you are an exempt worker such as a sworn police officer, ambulance paramedic, or firefighter).
Psychological injuries, such as PTSD and depression claims, must meet a minimum 15% WPI threshold.
These lump sum compensation payments are designed to recognise the lasting effects of your aggravated injury on your ability to work, live independently, and enjoy life as you once did.

Why Insurers Might Deny Claims Involving Pre-Existing Conditions
Claims involving aggravated pre-existing conditions can be more complicated than standard workplace injuries. Insurers often look for reasons to deny or minimise these claims, arguing that the injury wasn’t caused by work or that it’s simply part of a natural decline. Understanding their common tactics can make a big difference in the success of your claim.
“No New Injury” Defence
One of the most common reasons insurers reject these claims is by arguing that there is no new injury. They may say your current symptoms are the result of an underlying condition, not something caused or worsened by your job.
This defence is often used in cases involving:
Long-term back or joint issues
Old sports or motor vehicle injuries
Degenerative conditions like arthritis
However, under NSW workers compensation law, you don’t need a brand-new injury to be eligible. If your work duties have aggravated or worsened your condition in a meaningful way, you may still have a strong claim, even if the original injury occurred years ago.
Lack of Clear Medical Causation
Another common reason for denial is the lack of clear medical evidence linking your work to the aggravation. Insurers may argue that:
Your symptoms haven’t changed significantly
Your condition would have worsened naturally over time
There’s no recent incident or activity to explain the aggravation
This is why strong medical documentation is crucial. It’s not enough to show that your condition has worsened, you must also prove that your current job duties made a contribution to that deterioration. Simply having a pre-existing condition is not, on its own, enough to qualify for compensation.
At Withstand Lawyers, our experienced workers compensation team knows exactly what evidence is needed to build a strong, successful claim. We work closely with medical specialists and fight to ensure insurers recognise the true impact of your aggravated injury.

TPD Claims For Workers With Aggravated Pre-Existing Injuries
If your aggravated injury or condition is preventing you from returning to work, you may be entitled to Total and Permanent Disability (TPD) compensation through your superannuation.
Many workers are unaware that TPD insurance is often included in their super fund automatically, and a successful claim can result in a significant lump sum payment to help secure your financial future. Typical TPD payouts range between $50,000 to $350,000, but your cover may be even higher.
To qualify for a TPD payout, you generally need to show that:
You are unable to return to work in any capacity that matches your education, training or experience
Your injury or condition has been properly assessed and documented by medical professionals
You meet the specific policy requirements set by your superannuation fund
A TPD claim is separate from a workers compensation claim, and you may be eligible to claim both at the same time. TPD claims do not require you to prove that your employer was at fault, and your injury does not need to be work related.
At Withstand Lawyers, we handle both workers compensation and TPD claims, making sure no entitlements are missed. If your aggravated pre-existing condition has prevented you from returning to work, our team of TPD lawyers can review your eligibility and manage the entire TPD claim process on your behalf, from paperwork and medical reports to liaising with your super fund and insurer. Contact us today for a free claim assessment to find out if you have TPD cover and what you could be entitled to claim.

Aggravation of Pre-Existing Injury FAQs
If you use an IRO-approved lawyer, the Independent Review Office (IRO) will fund your legal fees and disbursements for most workers compensation matters.
This means:
You don’t pay to have your claim assessed.
You don’t pay your lawyer’s fees while your claim is running.
In most cases, you will never be out of pocket for legal costs.
At Withstand Lawyers, we are IRO-approved lawyers, so our clients benefit from this funding arrangement.
In NSW, you have six months from the date your injury was aggravated to make a workers compensation claim. However, the time limit may be extended if:
You didn’t realise the seriousness of your condition straight away.
The aggravation developed gradually over time.
You have a reasonable excuse for the delay.
It’s always best to make a claim as soon as possible to avoid complications with insurers and to protect your entitlement to benefits. Contact us today for a free claim assessment and personalised advice relating to your claim.
You will need medical evidence linking your current symptoms to your work duties. This usually includes medical records, doctor’s reports, diagnostic imaging, and possibly an Independent Medical Examination (IME).
At Withstand Lawyers, we work with medical specialists to ensure your case is backed by strong medical proof. Contact us today to see how we can help you make a strong claim after an aggravated injury at work.
If your job significantly worsened your condition, you may be entitled to the same types of benefits as someone with a new injury, including weekly payments, medical expenses, and lump sum compensation. The key is showing that your work duties played a real role in the deterioration of your condition.
To make a claim in NSW, you’ll need to:
Report the injury to your employer as soon as possible, explaining how your work has aggravated your condition.
Visit your doctor and request a Certificate of Capacity that outlines your diagnosis, treatment plan, and work capacity.
Submit the claim to your employer or directly to their insurer, including medical evidence and details of your injury. The insurer will then assess your claim.
Having a workers compensation lawyer involved early can help ensure your claim is complete, supported by strong medical documentation, and not unfairly rejected. Contact our experienced team of workers compensation lawyers today for a free claim assessment to see how we can help maximise your entitlements.
No. It’s illegal for an employer to fire or disadvantage you simply for making a legitimate workers compensation claim. If this happens, you may have grounds for an unfair dismissal or general protections claim.
No Win No Fee means you only pay legal fees if your claim is successful. This arrangement gives you peace of mind that you can make a claim without risk of being left out of pocket.
However, it’s important to remember that not all No Win No Fee lawyers are the same. Some firms may have hidden costs or unclear conditions. At Withstand Lawyers, we make our No Win No Fee agreement simple and transparent, so you always know where you stand.
