AustraliaMy insurer says I didn't report the accident promptly enough and won't pay. Is there a strict time limit?
There is no single strict nationwide time limit in Australia for reporting a car accident to your insurer, but most policies require 'prompt' or 'as soon as practicable' notification — typically within 24–72 hours — and delays can void cover if they prejudice the insurer.
What the Law Says
Australian insurance law does not set a universal statutory deadline for accident reporting. Instead, obligations arise from the Insurance Contracts Act 1984 (Cth) and the specific wording of your insurance policy.
Under the Insurance Contracts Act 1984 (Cth), your duty is to notify the insurer 'as soon as practicable' after an incident — not necessarily within a fixed number of days. What's 'practicable' depends on your circumstances (e.g., injury, hospitalisation, lack of phone access).
The insurer can only refuse a claim for late notification if the delay caused them 'prejudice' — meaning it materially harmed their ability to investigate, assess liability, or recover costs. Mere lateness isn't enough.
Importantly, your insurance policy contract sets the primary reporting requirement. Most Australian motor policies state you must report 'promptly' or 'within 24 hours', but these are contractual terms — not statutory deadlines — and must still be read consistently with the Insurance Contracts Act.
Statutory TextThe insured shall give notice of the occurrence of any event that may give rise to a claim under this insurance as soon as practicable after the insured becomes aware of the event.
— Insurance Contracts Act 1984 (Cth), s. 54 — Effect of breach of duty of utmost good faith
Statutory TextWhere the effect of a provision of a contract of insurance would be to deprive the insured of cover… because of a failure… to comply with a provision… the insurer is not entitled to rely on the provision… unless the failure… was fraudulent or the insurer has been prejudiced by the failure.
— Insurance Contracts Act 1984 (Cth), s. 54(1)
What to Do
Check your policy document for its exact reporting clause — look for phrases like 'as soon as practicable', 'within 24 hours', or 'promptly'.
Gather evidence explaining any delay (e.g., medical certificates, SMS timestamps, witness statements).
Write to your insurer within 7 days, stating your reason for delay and requesting written confirmation of whether prejudice occurred.
If rejected, escalate to the Australian Financial Complaints Authority (AFCA) — they assess whether the delay was reasonable and whether prejudice was proven.
