The simple version
The 28-day rule is the deadline for getting your statutory benefits backdated to the day of the crash. Get the CTP claim form in within 28 days and the weekly income payments and medical funding can be paid from day one. Submit later and benefits usually only start from the day you actually got it in.
What that means in practice: every week you delay past the 28-day window is, typically, a week of unfunded income loss and unfunded medical treatment. For someone who can't work, that gap can be thousands of dollars.
What "submitting the claim" actually means
You don't need a finished, perfect claim. You need to get a CTP claim form (the Personal Injury Claim Form) to the right insurer, with enough detail to start the process. Missing fields can be filled in later. Medical reports can come later. The point is to start the clock running.
See the CTP claim form explainedfor what's actually on it and what you need to bring.
What if you've missed the 28 days
Two things to know.
One — your claim is still alive.Missing the 28-day window doesn't end your claim. You can still submit later and still get future statutory benefits, and you can still claim damages later if the injury is serious.
Two — there's a "full and satisfactory explanation" pathway.NSW law allows for late submission where there's a good reason for the delay. Examples that often qualify:
- Hospitalisation that kept you out of action for weeks.
- Serious mental health impact from the crash.
- Language barriers — couldn't read the forms or didn't know who to call.
- Simply not knowing the scheme existed (very common — most people don't).
- Delayed onset of injury — pain that surfaced weeks after the crash.
None of these are automatic. The insurer (or, on review, the Personal Injury Commission) looks at the explanation case-by-case. But we've had statutory benefits backdated to day one for clients who got their claim in months late, because the reason for the delay was reasonable.
The other timelines that matter
The 28-day rule is the most urgent, but it's not the only deadline:
- 3 months. The internal review window for any individual insurer decision you want to dispute.
- 6 months from the crash. The deadline for getting the full personal injury claim form in for damages.
- 3 years from the crash. The hard limit for starting damages proceedings.

The trap with "I'll wait and see"
The most common mistake we see: someone walks away from a crash feeling sore but okay. They figure they'll wait a week or two and see if it settles. Two or three weeks later, the pain is worse not better — and now they've burned half the 28-day window without even knowing it existed.
Soft-tissue injuries, whiplash, and shoulder strain often peaktwo to six weeks after a crash. By the time you're sure, you might be out of time. Submitting early doesn't commit you to anything — if you turn out to be fine, the claim just doesn't go anywhere. If you turn out to be hurt, you're covered from day one.
What we do for you
One phone call gets the form in. We take the details, send it to the right insurer, and start the statutory benefits clock from day one. If you've already missed the 28 days, we still take the call — we write the "full and satisfactory explanation" properly and push for the backdate where it's achievable.
