If you’re ‘permanently impaired,’ you may be eligible for a lump sum payment in addition to your weekly wage replacement and medical benefits.
Generally speaking, you will need to meet a minimum percentage of Whole Person Impairment (WPI) to qualify. WPI is the total impairment you’ve suffered due to your injury.
Each state has its own minimum WPI threshold, with higher WPI percentages often resulting in larger payouts.
Below, we explore the requirements for a permanent impairment claim in each state.
In most states, you’re automatically entitled to workers compensation after a workplace injury. This covers things like lost wages, medical care and rehabilitation. However, if your injury permanently affects your life, you may also be eligible for an additional lump sum payment.
To begin a claim for permanent impairment, your Whole Person Impairment (WPI) must be assessed.
WPI is a measure of the overall impairment resulting from your injury. Your WPI is assessed as a percentage, and you must meet your state’s minimum threshold before starting a claim.
It’s critical to note that your WPI can only be assessed after your condition stabilises. This means it’s reached maximum medical improvement and is unlikely to improve with further treatment.
In New South Wales, your WPI must be assessed at 11% or greater for physical injuries. This increases to 15% for psychological injuries.
Importantly, your WPI is only based on your primary injury. This must be an injury or illness directly resulting from work, such as a back injury or stress-related anxiety. In contrast, if you develop depression after injuring your back, this is considered a secondary injury and will not contribute to your WPI.
If you have multiple physical injuries, each will be assessed individually and given its own WPI. The percentages are then added to produce your total WPI.
A consequential injury is a physical injury that results directly from your primary injury. For example, you might suffer a right shoulder injury and compensate by using your left shoulder more than usual. If you develop pain in your left shoulder as a result, both injuries will be assessed. Their percentages will then be added together to form your total WPI.
Your WPI is assessed based on guidelines developed by the State Insurance Regulatory Authority (SIRA). The assessment looks at:
Your assessor will be an independent, registered medical practitioner with experience and qualifications related to your injury.
The lump sum payment you receive depends on two factors:
As an example, if your injury occurs between 1 July 2023 and 30 June 2024, you can expect the following compensation:
Percentage of WPI | Compensation range |
< 10% | $0 |
11 – 20% | $27,790 – $60,460 |
21 – 30% | $64,090 – $96,760 |
31 – 40% | $102,690 – $156,510 |
41 – 50% | $162,490 – $216,310 |
51 – 60% | $299,300 – $382,170 |
61 – 70% | $465,040 – $547,910 |
71 – 74% | $630,770 |
75 – 100% | $713,660 |
Based on SIRA Workers Compensation Benefits Guide October 2023
If your injury occurred in a previous year, see the compensation calculation table in 6.5.5 of the Guide.
In Victoria, three minimum WPI thresholds may apply to you:
Importantly, your injury must be a primary impairment, meaning it directly results from your work. For example, you might suffer a back injury caused by heavy lifting or develop Post-Traumatic Stress Disorder (PTSD) due to workplace bullying or witnessing a traumatic event at work.
If you develop another injury because of your first injury, this is a secondary impairment. Unfortunately, you cannot claim compensation for secondary impairments. For example, if you’re physically injured at work and subsequently develop depression, you can only claim for the primary physical impairment.
If you have multiple primary injuries, each will be given an individual WPI assessment. The percentages are then added to produce your total WPI percentage.
Your WPI is assessed by a medical professional who specialises in your injury. They will look at:
Your lump sum payment covers your financial losses, including lost income and medical expenses.
This compensation is paid according to:
If you suffered a spinal injury between 1 July 2023–30 June 2024, you could be entitled to:
Combined percentage of WPI | Compensation range |

For injuries before 1 July 2020, you should refer to the relevant calculation table.
In Queensland, WPI is called DPI (Degree of Permanent Impairment). There is no minimum DPI required to claim compensation. However, your DPI affects how much compensation you receive.
Your DPI is based on the following:
After your injury, WorkCover Queensland will have your DPI assessed. They will then offer you a lump sum payment, which you can accept, reject or defer.
Your DPI percentage may impact this decision. If your DPI is less than 20%, you must decide between accepting a lump sum offer or claiming common law damages.
For a DPI of 20% or higher, you can accept both the lump sum and pursue a common law claim.
If you have multiple injuries, you are only entitled to compensation for your primary injury. You cannot combine the DPI of multiple injuries.
If your DPI is less than 30%, your compensation is calculated by multiplying your percentage of DPI by the ‘maximum compensation statutory amount’. From 1 July 2023 to 30 June 2024, this amount is $380,575.31. This means for every 1% of DPI, you’re entitled to $3,805.75.
For example, if your DPI is five, your maximum lump sum compensation would be 5% of $380,575.31, which is about $19,028.77.
The maximum amount is updated each financial year and increases with inflation.
The calculation is more complex if your DPI is greater than 30%. Your payment is still calculated based on your 1% of DPI, but you receive an additional amount on top. The exact amount you get depends on your DPI and the rules in Schedule 3 of the Workers Compensation and Rehabilitation Act.
If you were injured between 15 October 2013 and 30 January 2015 (inclusive), you are only eligible for lump sum compensation if:
In the ACT, workplace injury claims are not subject to a minimum WPI threshold.
ACT legislation includes a list of all injuries for which lump sum compensation can be claimed. You are entitled to claim for multiple injuries, but your total compensation cannot exceed $150,000.
Each injury is allocated a percentage of the maximum single injury compensation (currently $100,000 and indexed annually). For example, a permanent back impairment qualifies you for 60% of the maximum compensation, meaning you’d receive $60,000.
You can find the complete list under Schedule 1 of the Workers Compensation Act.
Western Australia does not have a minimum WPI threshold for lump sum compensation claims. Instead, a relevant medical professional must assess your injury or illness. The assessment must conclude that:
An approved medical specialist assesses your injury. They will consider whether:
You may be entitled to a lump sum payment if your injury results in permanent impairment.
Western Australia caps the total possible compensation at $224,921 (the ‘prescribed amount’).
Every injury is allocated a percentage of the prescribed amount. For example, permanent back impairment is allocated 60%. This means you are eligible for a maximum lump sum of $134,952.60.
You can find the complete list of recognised injuries and illnesses in Schedule 2 of the Workers Compensation and Injury Management Act.
It’s vital to note that the prescribed amount includes both weekly payments and any lump sum for permanent impairment. As a result, you can only claim a lump sum payment if you have not already met the prescribed amount through weekly payments.
In Tasmania, you are entitled to compensation if your physical injuries result in a WPI of 5% or more. For psychological injuries, this increases to a minimum of 10% WPI.
A qualified medical assessor determines your WPI based on whether:
Tasmania’s guidelines define ‘impairment’ as a negative deviation from a person’s normal health status.
As a general rule, the loss of a foetus over 16 weeks old is treated as a permanent impairment and given a WPI of 20%.
If your WPI is between 5 – 70% (for physical injuries) or 10 – 70% (for psychological injuries), you will receive compensation based on the formula in section 71 of The Act. The calculation is based on the ‘basic salary’ (currently $1005.77 as of 1 January 2023).
For a WPI of 70% or more, you automatically receive 415 basic salary ‘units’. This totals $417,394.55 and applies to both physical and psychological injuries.
You only have one chance to get compensation, so it’s essential to speak to a lawyer before starting your claim. An experienced lawyer can help you navigate state requirements and challenge your WPI assessment if you’re unhappy with the result.
In addition, we’ll also determine whether you have a common law damages claim, ensuring you get maximum compensation for your injury.
