A threshold injury includes soft tissue injuries and minor psychological or psychiatric injuries.
Once you have made a claim for personal injury benefits under the new Motor Accident Injuries Act 2017 which is effective for accidents after 1 December 2017, the insurer will pay weekly payments of compensation (if you are unable to work) and medical expenses for a period of twelve months.
You may be eligible for 52 weeks of compensation if you have a threshold injury.
What is a threshold injury?
For the purposes of the Act, a threshold injury is any one or more of the following:
- Soft tissue injury
- A minor psychological or psychiatric injury.
AÂ soft tissue injury is defined as:
An injury to the tissue that connects, supports or surrounds other structures or organs of the body (such as muscles, tendons, ligaments, menisci, cartilage, fascia, fibrous tissues, fat, blood vessels and synovial membranes) but not an injury to nerves or a complete or partial rupture of tendons, ligaments, menisci or cartilage.
The Motor Accident Injuries Regulations adds the following:
An injury to a spinal nerve root that manifests in neurological signs (other than radiculopathy) is included as a soft tissue injury for the purposes of the Act.
A minor psychological or psychiatric injury is defined as:
A psychological or psychiatric injury that is not a recognised psychiatric illness.
The Act commenced on 1 December 2017 and as yet there have been no cases to determine how the medical assessors will determine what is and is not a threshold injury.
If you believe you have more than a minor injury as defined by the Act, you will need to contact a Lawyer to assist you in disputing this through the dispute resolution system. This application must be made within 28 days of the decision made by the insurer.
Once an application is made you will be referred to an independent medical assessor who will decide whether the injury is a threshold injury in accordance with the Act.
Making a compensation claim
Within that twelve month period, the insurer will make a decision in relation to:
- Whether or not the motor accident was your fault or the fault of the other driver; and
- Whether you have a threshold  injury as defined by the Motor Accident Injuries Act.
You are only entitled to continue to receive weekly payments after 26 weeks if the insurer decides that the injury was not your fault and that you do not have a threshold injury.
If the insurer decides either that the accident was your fault or that you have a minor injury as defined in the Act then all personal injury benefits cease after 52 weeks and you are not entitled to claim any further compensation.
Payments after 52 weeks
To continue to receive statutory benefits of weekly compensation and medical expenses after 52 weeks and have an entitlement to make a common law claim for pain and suffering and loss of future income, it must be determined that:
- The accident was not your fault but the fault of the other driver; and
- That you do not have a threshold injury.
Should you require assistance with your minor injury, you should contact us as soon as possible.

Featured Testimonial
I cannot speak highly enough of my experience with this workers Compensation team. When I first reached out, I was completely overwhelmed and unsure about the process. I hit rock bottom - unable to return to work, struggling emotionally, and feeling like I had no direction. From the very beginning, the solicitors were nothing short of amazing. They were patient, understanding and incredibly supportive at a time when I needed it most. They took the time to explain every step in a way I could understand, never making me feel rushed or alone. Their professionalism was matched only by their compassion and that combination made all the difference. Throughout the entire journey, I felt heard, respected and genuinely cared for. They fought for me when I didn’t have the strength to fight for myself and thanks to their dedication, I was able to get the outcome I needed to rebuild my life. If you’re unsure, scared or feeling lost like I was, I can confidently say you will be in the best hands with this team. They helped me through one of the hardest chapters of my life, and I am truly grateful. I can’t thank or recommend Garling & Co Lawyers enough.
Matthew Garling and his team have provided incredible support and guidance throughout my MVA damages claim this year, and I can’t thank them enough for making this journey feel like such a breeze. When I initially engaged Garling & co, I had no understanding of what was ahead. I was anxious and unsure about the process, while also navigating the physical challenges of my injuries. With assurance that my matter was being handled with high level of expertise, professionalism and integrity, I was able to focus on recovery instead. Throughout the process, Matthew and Allison have been honest, straightforward and efficient in all communication; being a supportive buffer in all dealings with the insurer, and consistently committed to a successful outcome. The outcome was excellent, and it is with huge relief and great thanks that I can put this matter behind me. I would highly recommend the services of Garling and co for any injury claims of a similar nature, and I’m forever grateful to Matthew and his team.
A big thank you to Matthew for his expertise, dedication, and genuine care in handling my matter. The outcome exceeded my expectations, and I am truly grateful for the excellent work of his entire team. Outstanding results - highly recommended.
