Motor Accident Compensation in South Australia: CTP Claims, Benefits and Time Limits

South Australia runs two separate compensation schemes on one compulsory insurance product: fault-based CTP damages under the Civil Liability Act 1936, claimed against the at-fault driver's insurer, and a separate no-fault Lifetime Support Scheme that pays for catastrophic injury regardless of who caused the crash.

This guide covers compulsory third party, CTP, motor accident insurance in South Australia under the Motor Vehicles Act 1959, the Civil Liability Act 1936 and the Motor Vehicle Accidents (Lifetime Support Scheme) Act 2013, current as of 18 August 2026. It sets out how a CTP claim works, what the Injury Scale Value threshold means for damages, how the separate Lifetime Support Scheme operates, and the time limits that apply to each. It does not cover other states' CTP schemes, comprehensive or third party property insurance, or Australia's general civil statute of limitations outside motor accidents.

How South Australia's CTP Scheme Works

Every vehicle registered in South Australia must carry a Policy of Insurance under Part 4 of the Motor Vehicles Act 1959. This is the state's compulsory third party, or CTP, insurance: it pays compensation to a person injured by an at-fault driver of the insured vehicle. The injured person claims against the at-fault driver's CTP insurer, not their own, and CTP does not cover a driver who was entirely responsible for causing the accident, except for a driver under 16.

The amount of damages a successful CTP claim can recover is set separately, by Part 8, section 52, of the Civil Liability Act 1936. That section fixes both the formula for non-economic-loss damages and the threshold a claimant must clear before any non-economic-loss damages are available at all, covered in What You Can Receive below.

Sitting alongside general CTP is the Lifetime Support Scheme, the LSS, established under the Motor Vehicle Accidents (Lifetime Support Scheme) Act 2013. The LSS is structurally separate from CTP and pays for the treatment, care and support of a person who sustains a serious, listed injury in an SA motor vehicle accident, regardless of fault. Eligibility under section 24 of the LSS Act does not turn on who caused the accident at all, so a driver who caused their own crash can still access LSS support even where their own CTP claim is refused.

Who Is Covered

CTP pays the other party, not the at-fault driver. If a driver was entirely responsible for the accident, that driver has no CTP claim of their own for their injuries, though they may still be eligible for the no-fault Lifetime Support Scheme if the injury is severe enough. CTP does not cover vehicle or property damage; that sits with separate comprehensive or third party property insurance, outside the CTP scheme.

If the at-fault vehicle cannot be identified, for example a hit and run, or was unregistered or uninsured at the time, an injured person can still bring a nominal defendant claim under sections 115 and 116 of the Motor Vehicles Act 1959. In practice, the CTP Regulator allocates a nominal defendant claim to one of the licensed CTP insurers to handle; notice of the claim should be given as soon as reasonably practicable once it becomes clear the vehicle cannot be identified or was uninsured.

Bicycles, e-scooters and other personal mobility devices are not motor vehicles for CTP purposes, so a rider who causes injury to someone else is not a CTP matter. A cyclist or rider who is hit by a motor vehicle, however, can claim against that vehicle's CTP insurer in the ordinary way.

LSS eligibility is broader in one specific sense: it applies regardless of fault, to a defined list of serious injury types, currently brain injury of moderate to severe severity, spinal cord injury, severe burns, blindness and amputation.

Time Limits and How to Claim

The Motor Vehicles Act 1959 itself does not set a fixed notice period for a CTP injury claim; section 126A(2)(a) leaves the exact timing to the regulations. In practice, the CTP Regulator states the operative rule directly: if the accident happened more than 6 months ago, the claimant must give the insurer a reason for the delay, and if the accident happened more than 3 years ago, the claim will generally not be accepted, except in very limited legal exceptions. Treat 6 months as a soft, practical deadline the insurer can excuse, and 3 years as the hard outer limit.

That 3-year figure is confirmed independently by the Limitation of Actions Act 1936. Section 36(1) requires an action for damages that includes personal injury to be commenced within 3 years after the cause of action accrued, with section 36(1a) allowing the clock to start later for a latent injury, from when it first comes to the person's knowledge.

A claim form should include the South Australia Police report number where one exists. A CTP claim can be sent directly to the at-fault driver's insurer, or, for a nominal defendant claim, to the CTP Regulator, who allocates it to an insurer.

The Lifetime Support Scheme has its own, separate application window: an initial application must generally be made within 3 years of the date of the accident, under section 25(7) of the LSS Act 2013, the same length as the general personal injury limitation period but running from the accident date itself, not from when a CTP claim is accepted or refused. An LSS application can be made by the injured person, a family member, or the vehicle's CTP insurer, and the Lifetime Support Authority can also be notified of a potential case earlier, by SA Police or a treating hospital, ahead of a full application.

What You Can Receive

Economic loss, lost earnings beyond the first week and the impact on future earning capacity, can be claimed under a CTP claim without any threshold gate.

Non-economic-loss damages are different: they require an Injury Scale Value, or ISV, of more than 10. The ISV is a whole-claim numerical value from 0 to 100 set under section 52(3) of the Civil Liability Act 1936, specific to motor accident claims, and assessed by a medical practitioner applying the Motor Accident Injury Assessment Scheme. It is not a whole-person-impairment percentage. Below an ISV of 11, a court, not the insurer, can still award damages only where the consequences are exceptional compared with similar cases and applying the threshold would be harsh and unjust.

The dollar value attached to each ISV point is indexed every 1 July under section 52(7), by the change in the Consumer Price Index. As of the 2026-27 financial year of the accident date, the CTP Regulator's published Table ISV Damages sets these figures: an ISV of 11, the threshold minimum, at $4,320; an ISV of 30 at $31,680; an ISV of 50 at $129,600; an ISV of 65 at $237,600; and an ISV of 79 or above, the top of the published table, at $431,980. These figures move roughly 4 percent each year with CPI, so a figure from an earlier financial year should not be relied on for a current claim.

Two further heads of damage also depend on the ISV threshold. Gratuitous services, the value of care or domestic help provided by a family member, are available where the ISV is 11 or more and the care runs to 6 or more hours a week for 6 or more consecutive months, capped at 4 times the state average weekly earnings unless a court allows more. Loss of consortium, a claim by a spouse or domestic partner, is available where the injured person's ISV is 11 or more.

Catastrophic Injury: the Lifetime Support Scheme

Where CTP pays scheduled damages tied to the ISV, the Lifetime Support Scheme pays for necessary and reasonable treatment, care and support needs for as long as they are needed, with no ISV or dollar cap, funded on a needs basis rather than as a scheduled lump sum. Eligible injuries are brain injury of moderate to severe severity, spinal cord injury, severe burns, blindness and amputation.

The LSS began on 1 July 2014. Before it existed, a seriously injured person with no one else to sue, for example a driver who caused their own single-vehicle crash, had no ongoing compensation scheme to turn to at all. The LSS closed that gap by removing fault from the eligibility test entirely.

CTP Premiums

CTP in South Australia is not a single, centrally fixed price. Five licensed insurers, AAMI, Allianz, NRMA, QBE and Youi, compete for business within price bands the CTP Regulator sets at least annually, using independent actuarial advice. Every insurer must offer the same Policy of Insurance, with terms set by the Regulator rather than negotiated by the insurer, but insurers compete on price, service and incentives within the approved range. A new premium takes effect 2 months after the Regulator approves it.

Within a vehicle class, all owners pay the same insurer-quoted premium regardless of their individual driving history, a community rating model rather than a no-claims-discount system. The amount collected at registration also includes a CTP Scheme Services fee for scheme administration, stamp duty and GST, alongside other unrelated registration charges.

The Lifetime Support Scheme is funded separately, through an LSS Fund Levy paid whenever a vehicle is registered, exempted or permitted, set annually from independent actuarial advice and published in the South Australian Government Gazette.

Disputes and Legal Costs

A CTP dispute starts with the insurer: raise it with the Claims Consultant handling the file, then escalate to the insurer's State Claims Manager if unresolved. The insurer must attempt resolution within 10 business days and give a final written response within 30 calendar days.

Two free options follow if the claimant still disagrees: Internal Dispute Resolution, where a different team at the same insurer reviews the decision, or conciliation, where an independent conciliator convenes a meeting between the claimant and the insurer. A claimant can also complain to the CTP Regulator, but the Regulator can only review whether the insurer complied with the Regulator's rules; it cannot make the insurer change a decision the claimant is unhappy with.

Legal costs on a CTP claim follow a specific rule rather than a general no-win-no-fee arrangement: a claimant does not need a lawyer to lodge or manage a claim, and if the final compensation exceeds $25,000, part of the legal fees can be recovered when the claim settles. If the compensation is $25,000 or less, the claimant pays their own legal fees.

LSS disputes run on a different, and more formal, track. An interested party can apply to have a determination reviewed by a review officer under section 34 of the LSS Act, then appeal the review officer's decision to the South Australian Civil and Administrative Tribunal under section 35. Certain disputes can also go to an expert review panel, and a participant can ask for a review of their assessed treatment, care and support needs within 28 days of being given notice of the assessment.

Interstate Accidents

Where the vehicle that caused the accident is registered interstate, the claim is managed by that vehicle's interstate CTP insurer, not an SA insurer. The claimant still lodges a South Australian Injury Claim Form, and sends it to the at-fault vehicle's CTP insurer; the SA CTP Regulator can help direct a claimant to the relevant interstate authority.

Generally, the CTP cover attached to a vehicle's own registration follows that vehicle wherever the accident happens, but a claimant in the reverse situation, an SA-registered vehicle causing an accident in another state or territory, should confirm the position directly with their insurer rather than assume it mirrors the rule above.

Police Reporting and Related Claims

A driver involved in an accident where anyone was injured or killed must report it to South Australia Police. A driver who caused the accident must also complete and send an Accident Report Form to their own CTP insurer.

A motor accident on a work journey, commuting to or from work or travelling for work, can also raise a workers compensation claim alongside, or instead of, a CTP claim; see recordinglaw.com's guide to workers compensation in South Australia for how that scheme interacts with a CTP claim. An at-fault driver may also face demerit points or drink driving penalties as a separate consequence of the same accident; see the guides to South Australia demerit points and drink driving penalties in South Australia.

Frequently Asked Questions

What is the time limit to make a CTP claim in South Australia?

The CTP Regulator treats 6 months after the accident as a soft deadline, requiring an explanation for a later claim, and 3 years as the hard outer limit, matching the general personal injury limitation period in section 36(1) of the Limitation of Actions Act 1936.

What is an Injury Scale Value and how does it affect a CTP claim?

The Injury Scale Value, or ISV, is a 0 to 100 scale set under section 52(3) of the Civil Liability Act 1936 for motor accident injuries. Non-economic-loss damages are only available where the ISV is more than 10, so 11 or above, except in exceptional cases a court allows below that.

Does the Lifetime Support Scheme require proving fault?

No. Eligibility under section 24 of the Motor Vehicle Accidents (Lifetime Support Scheme) Act 2013 does not turn on fault at all, so a person can access LSS support for a qualifying catastrophic injury even if they caused their own crash.

Can I make a CTP claim if I do not know who caused the accident?

Yes. Sections 115 and 116 of the Motor Vehicles Act 1959 allow a nominal defendant claim where the at-fault vehicle cannot be identified or was uninsured. The CTP Regulator allocates the claim to one of the 5 licensed CTP insurers.

How much of my legal fees can I recover from a CTP claim?

If the final compensation is more than $25,000, part of the legal fees can be recovered when the claim settles. If it is $25,000 or less, the claimant pays their own legal fees, under the CTP Regulator's stated cost-recovery rule.

What happens if the at-fault vehicle is registered in another state?

The claim is managed by that vehicle's interstate CTP insurer. The claimant still lodges a South Australian Injury Claim Form, sent to the at-fault vehicle's insurer, and the SA CTP Regulator can help direct the claim to the right interstate authority.
