When a human driver causes a crash in Australia, the liability chain is well established — driver at fault, compulsory third-party (CTP) insurance covers the damage. But as robotaxi services prepare to launch, what happens when there is no driver at all?
\n\n
As Australian robotaxis move closer to reality, the question of robotaxi insurance and liability is becoming one of the most pressing legal challenges facing regulators and the insurance industry. Who pays when an autonomous vehicle causes an accident? And how will Australia’s $12 billion motor insurance market adapt?
\n\n
How Car Insurance Works Today
\n\n
Australia’s current motor insurance framework is built around the concept of driver fault. Every registered vehicle must carry CTP insurance (called “green slips” in NSW and “TAC” in Victoria) which covers injuries to other road users.
\n\n
Comprehensive and third-party property insurance are optional but common. In every case the system assumes a human driver made a decision that caused the incident. Premiums are calculated based on driver age, history and location.
\n\n
This model has worked for over a century. But it was never designed for a world where software makes the driving decisions.
\n\n
The Liability Shift: From Driver to Manufacturer
\n\n
When a robotaxi operates without a human driver, the traditional concept of “driver fault” breaks down entirely. If an autonomous vehicle’s sensors fail to detect a pedestrian or its AI makes the wrong decision at an intersection, who bears responsibility?
\n\n
Globally the answer is becoming clear: liability shifts from the driver to the vehicle manufacturer or fleet operator. This represents one of the biggest changes to product liability law in a generation.
\n\n
In the United States, companies like Waymo and Zoox already carry substantial commercial insurance policies covering their autonomous fleets. Waymo reportedly maintains coverage exceeding $100 million per incident. In China, operators like Baidu and WeRide face similar requirements under local regulations.
\n\n
What Australia’s Regulators Are Planning
\n\n
Australia’s National Transport Commission (NTC) has been developing the Automated Vehicle Safety Law (AVSL) since 2019. The framework introduces a new legal concept: the Automated Driving System Entity (ADSE).
\n\n
The ADSE is the company responsible for the self-driving technology. Under the proposed law, the ADSE — not a human driver — would bear primary responsibility for the vehicle’s behaviour while the automated system is engaged. This is a fundamental departure from existing Australian road law.
\n\n
Key elements of the proposed framework include:
\n\n
- \n
- ADSEs must demonstrate their vehicles meet a national safety standard before deployment
- ADSEs are responsible for all driving decisions made by the automated system
- A national regulator would oversee compliance and enforcement
- State and territory CTP schemes would need to be updated to accommodate the new model
\n

\n\n
The federal government has indicated the AVSL could be finalised by 2027, though state-level trials and approvals may begin earlier.
\n\n
How Insurance Premiums Could Change
\n\n
For everyday Australians the shift to autonomous vehicles could have a surprising upside: lower insurance costs.
\n\n
The logic is straightforward. Human error causes approximately 94% of all road crashes according to research from the US National Highway Traffic Safety Administration (NHTSA) and supported by Australian data from the Bureau of Infrastructure and Transport Research Economics (BITRE). If autonomous vehicles can significantly reduce crash rates — and early data from Waymo’s safety record suggests they can — then fewer accidents means fewer claims and lower premiums.
\n\n
However, the picture is more complex than that:
\n\n
- \n
- Repair costs are higher. Autonomous vehicles carry expensive sensor arrays including LiDAR units and cameras. A minor fender bender that costs $2,000 to fix on a regular car could cost $15,000 or more on a robotaxi
- Data and cybersecurity risks introduce new categories of liability that traditional motor insurance does not cover
- Software liability blurs the line between motor insurance and product liability insurance
\n
\n
\n
\n\n
The Insurance Council of Australia has acknowledged that the industry needs to prepare for these changes. However, detailed guidance on how robotaxi insurance will work under Australian CTP schemes has not yet been published.
\n\n
Who Pays in a Robotaxi Accident?
\n\n
Under the emerging Australian framework, the liability chain for a robotaxi accident would likely work as follows:
\n\n
Scenario 1: The autonomous system is engaged and causes a crash.
\nThe ADSE (the company behind the self-driving technology) bears primary liability. Their commercial insurance would cover damages. The passenger has no liability.
\n\n
Scenario 2: A human driver overrides the system and causes a crash.
\nTraditional driver-fault rules apply. The human driver’s CTP and comprehensive insurance would respond as they do today.
\n\n
Scenario 3: A software defect or sensor failure causes a crash.
\nThis falls under product liability law. The manufacturer could face claims under the Australian Consumer Law. Affected parties could pursue compensation through the ADSE’s insurance or directly through product liability action.
\n\n
Scenario 4: A cyberattack compromises the vehicle.
\nThis is largely uncharted legal territory. The AVSL is expected to include cybersecurity requirements but the insurance implications remain unclear.
\n\n
What This Means for Australian Riders
\n\n
For passengers using a future Australian robotaxi service, the practical implications are largely positive:
\n\n
- \n
- You would not need your own car insurance to ride in a robotaxi — the fleet operator’s commercial policy covers all incidents
- Compensation claims would likely be directed at the ADSE rather than requiring you to pursue an individual driver
- CTP costs for your personal vehicle could decrease over time as autonomous vehicles reduce overall crash rates
\n
\n
\n
\n\n
The transition period will be the most complex. During the years when human-driven and autonomous vehicles share the road, insurers will need to manage a hybrid model. Cities like Sydney and Melbourne where robotaxis are expected to launch first will be the testing ground for these new insurance frameworks.
\n\n
The Bigger Picture
\n\n
Robotaxi insurance is one piece of a much larger puzzle. The arrival of robotaxis in Australia will require coordinated reform across transport law, consumer protection and economic policy. The good news is that Australia has time to learn from international deployments and design a framework that protects consumers while encouraging innovation.
\n\n
The question is no longer whether autonomous vehicles will change Australia’s insurance landscape — it is how quickly the industry can adapt.
