South Australian compulsory third-party (CTP) insurers are facing a materially deteriorated risk environment in 2026, with motorcyclist fatalities in the state nearly tripling year-on-year and cyclist deaths reaching their highest annual level in at least three decades – all before the spring riding season has begun. According to data published by the Royal Automobile Association of South Australia (RAA) on August 27, 14 motorcycle riders have been killed on South Australian roads so far in 2026, compared with five at the same point in 2025. The South Australian Department for Infrastructure and Transport (DIT) separately confirmed that a further 77 motorcyclists had suffered serious injuries by mid-May 2026. Nine cyclists – eight on conventional bicycles and one on an e-bike – have also died since January, the highest annual total in at least 30 years based on available records. Five of those deaths occurred in regional South Australia and four in metropolitan Adelaide, with victims ranging in age from 17 to 76.
South Australia’s CTP scheme operates on a community rating model, meaning premiums for each vehicle class are set uniformly based on the claims experience of that class rather than individual driver history. The CTP Regulator sets upper and lower premium limits at least annually for each premium class using independent expert actuarial analysis, with the primary factors being the estimated number of injury claims resulting from accidents and the expected cost of those claims.
The scheme is underwritten by five government-approved private insurers: AAMI, Allianz, NRMA, QBE, and Youi. Motorcycles are divided into four CTP premium classes based on engine capacity, with premiums varying according to vehicle class and, where applicable, garaging location. Under the community rating model, changes in claims experience are considered at the premium-class level rather than being reflected immediately in an individual policyholder’s premium. The sharp increase in motorcycle fatalities, alongside the reported 77 serious injuries, is therefore an adverse road-safety indicator that could be relevant to future actuarial assessments of motorcycle CTP risk, although fatalities and serious injuries alone do not determine premiums.
A detail relevant to how the industry reads RAA’s public advocacy: as of July 1, 2025, Allianz Australia Insurance Limited acquired RAA Insurance Limited, which has since been renamed Allianz South Australia Insurance Ltd. Under a 20-year exclusive distribution agreement, Allianz now underwrites all RAA home and motor insurance products under the RAA brand. Allianz is also one of the five CTP underwriters in South Australia. RAA’s call for a $10 million State Bicycle Fund is therefore not purely an advocacy position – its underwriting partner has a direct commercial interest in the infrastructure improvements RAA is publicly recommending. Brokers and market analysts reading RAA’s road safety statements should factor that alignment into their assessment of the campaign.
South Australia’s 2026 motorcycle toll is not isolated. National Road Safety Data Hub figures show that over the period 2017 to 2023, annual motorcyclist fatalities grew from 211 to 253, an increase of 20%, while motorcyclist fatalities as a proportion of all road deaths increased by three percentage points over the same period.
The inclusion of an e-bike rider in South Australia’s 2026 cyclist toll highlights a growing issue for personal lines brokers. RAA reported that eight cyclists and one e-bike rider had been killed on South Australian roads since January. In Australia, compliant pedal-assist e-bikes are generally treated as bicycles rather than motor vehicles, meaning they do not require vehicle registration, a driver’s licence, or compulsory third-party insurance. Devices that do not meet the applicable requirements, including those that have been modified to increase their power or assisted speed, can fall outside the rules applying to compliant bicycles. For brokers, establishing what type of e-bike a client owns, how it is powered, and whether it has been modified is therefore important when assessing the appropriate personal lines cover and potential liability exposures. Policy coverage will ultimately depend on the terms and conditions of the relevant insurance product.
RAA’s Charles Mountain connected the fatality trend to infrastructure. “RAA has consistently called for a $10 million State Bicycle Fund to expand and improve cycling infrastructure across South Australia. Better-designed and better-separated cycling networks remain one of the clearest ways we can protect vulnerable road users long term,” Mountain said.
Nationally, around 85% of reported cyclist casualty crashes involve another vehicle, most often a light vehicle, while around 25% occur when two vehicles, including the cyclist, approach an intersection from perpendicular or opposing directions. The data, covering reported crashes from 2008 to 2013, highlights the types of road environments in which cyclists face elevated collision risk. For insurers and brokers, the findings provide context for considering how road design and separation measures could influence the frequency and severity of cyclist-related losses, although the crash data does not by itself establish an impact on insurance claims.
Mountain also flagged the seasonal dimension: “As we head into spring, when more cyclists and motorcyclists typically return to our roads, we’re urging everyone to be alert and look out for one another.” No government response to the RAA’s infrastructure funding call had been announced as of the date of publication.
