Understanding Insurer Decisions on Return to Work After a Car Accident in NSW
A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
After a car accident in NSW, your ability to return to work is assessed by your insurer under the Motor Accident Injuries Act 2017 (MAIA). Insurers base their decisions on medical evidence, your work capacity, and the SIRA Motor Accident Guidelines. In Greater Sydney, these assessments follow the same legal framework as elsewhere in NSW, but local medical providers and employment conditions may influence the outcome. Insurers are not required to accept your employer’s return-to-work plan without review. They may request a formal work capacity assessment to determine if you can perform your pre-accident duties or suitable alternative work.
What Insurers Consider When Assessing Return to Work
Insurers assess return to work based on several factors under the MAIA and SIRA guidelines. The primary consideration is your medical condition and functional capacity. Your treating medical practitioner must provide a detailed report outlining your current physical and mental health, any restrictions, and whether you can return to work with or without modifications. This report must include objective findings such as range of motion, strength testing, and neurological assessments.
Insurers also review your pre-accident employment, including job duties, hours, and physical demands. They may request a vocational assessment if your injury affects your ability to perform your usual role. This assessment is conducted by a qualified vocational rehabilitation provider and evaluates your capacity to return to your previous job or to a different role that matches your abilities. The insurer may only deny return-to-work benefits if there is clear medical evidence that you are not fit for any suitable work, and that no reasonable adjustments can be made.
How SIRA Guidelines Influence Insurer Decisions
The SIRA Motor Accident Guidelines provide the operational framework for insurer decisions. These guidelines require insurers to act reasonably and in good faith when assessing return to work. They must consider all available medical evidence and not rely solely on a single report. Insurers must also give claimants a reasonable opportunity to respond to proposed decisions, including the right to request a review.
The guidelines state that an insurer must not unreasonably delay or refuse to approve a return-to-work plan that is supported by medical evidence and approved by a qualified rehabilitation provider. If your injury is not a threshold injury under MAIA, you may still be eligible for treatment and care benefits and weekly income payments during recovery, which can support a gradual return to work.
Practical Steps and Evidence That Matter
To support your return-to-work claim, gather and preserve the following evidence:
- A detailed medical report from your treating practitioner, including functional capacity and any work restrictions.
- Your pre-accident job description and a statement from your employer about your duties and hours.
- A vocational assessment report, if obtained.
- Records of any workplace modifications or return-to-work plans discussed with your employer.
- Photographs of your injury site, if relevant to your condition.
- Correspondence with your insurer, including any letters denying or limiting return-to-work benefits.
Keep all documentation in a single folder. Insurers may request this evidence at any stage of the claim process. Failure to provide it may delay or reduce benefits.
Time Limits and Dispute Options
There is no fixed time limit for requesting a return-to-work assessment, but you must notify your insurer within a reasonable time after deciding to return to work. Delays may affect the timing of weekly income payments and treatment benefits.
If your insurer denies your return-to-work claim or refuses to approve a suitable plan, you can request a review under the MAIA. If the review does not resolve the issue, you may apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. You must file the application within 12 months of the insurer’s decision, unless an extension is granted.
A Realistic Example: How a Decision Might Be Made
Example: Sarah, a 38-year-old office worker in Sydney’s inner west, was involved in a rear-end collision in July 2026. She sustained a whiplash injury and was off work for six weeks. Her doctor cleared her to return to work with a 20% reduction in hours and no heavy lifting. Her employer offered a modified role with reduced physical demands. The insurer initially refused to approve the modified role, citing a lack of documented functional capacity. After Sarah submitted a second medical report and a vocational assessment confirming her ability to perform the modified role, the insurer approved the plan and began weekly income payments to cover the reduced hours. The process took six weeks from submission to approval.
When to Seek Independent Advice
Insurer decisions can significantly affect your income and recovery. If you believe your insurer has made an unreasonable decision, or if you are unsure about your rights under the MAIA, it is advisable to seek independent legal or vocational advice. This is particularly important if your injury is complex, your employer is unwilling to accommodate you, or you have been denied benefits despite strong medical evidence.
