Willoughby: how car accident compensation works

Not for NSW CTP claims. Compensation depends on facts a calculator can't assess, such as whether your injury is more than threshold, your whole person impairment, your share of fault and your earnings history. Many of those aren't known until well into a claim. Treat any online figure with caution, and focus instead on the questions that decide your entitlements.

Only if your whole person impairment is more than 10%, and only as part of a common law damages claim. That means another driver must have been at fault, you must not have been mostly at fault, and your injury must be more than a threshold injury. If your impairment is 10% or less, you may still claim damages for lost earnings.

Generally not until 20 months after the accident, unless your whole person impairment is assessed as more than 10%. The claim must generally be made within 3 years of the accident. If you want weekly payments to continue beyond 2 years, lodge the damages claim within 2 years of the accident. Because these dates interact, it's worth getting advice well before the 2-year mark.

Under the NSW CTP scheme, treatment and care costs, and unpaid help from family and friends (called gratuitous care), generally sit outside a common law damages claim. Your treatment keeps being funded through statutory benefits instead, for as long as the benefit periods that apply to you allow. Damage to your vehicle isn't part of a CTP claim at all, because CTP covers personal injury only.

Generally 3 years from the accident. A later damages claim may be allowed only with a full and satisfactory explanation, so don't count on it. The earlier marker matters too: lodge within 2 years if you want weekly payments to continue past 2 years while the claim is pending. Statutory benefits run to much shorter deadlines of their own, so make sure that claim is in first.

Yes, in two ways. Weekly payments replace part of your income while you recover: up to 95% of pre-accident earnings for the first 13 weeks, then up to 80% or 85%, subject to an indexed maximum. If you qualify for common law damages, you can also claim past and future loss of earnings, called economic loss, without needing impairment above 10%.
