Australian motorists are facing continued pressure from rising car insurance premiums, with some comprehensive policies increasing by almost 60 per cent over four years. The increases are adding to household expenses and raising questions about how insurers calculate prices and explain annual premium changes to customers.

The issue was highlighted by a motorist whose comprehensive car insurance premium rose by 10 per cent at renewal, following a similar increase the previous year. The annual cost for the vehicle reached A$1,110, compared with A$703 in 2023. The example represents a 57 per cent increase over that period, despite the driver having a strong safe-driving rating.

The figures illustrate how insurance costs can rise even when a motorist's personal circumstances have not changed significantly. Insurers assess a range of factors when setting premiums, including the likelihood and cost of claims, vehicle repair expenses, replacement parts, labour costs and risks associated with particular locations.

Industry representatives have pointed to rising repair costs as a major contributor. The Insurance Council of Australia said the average motor insurance claim had increased by 32 per cent over four years, reaching A$6,266 in 2026. Higher vehicle replacement costs, shortages of spare parts, limited availability of skilled repair workers and the specialised equipment required for modern vehicles have all contributed to the pressure.

Modern vehicles can be more expensive to repair because they incorporate advanced electronics, sensors and safety systems. When these components are damaged, repairs may require specialised technicians and equipment, potentially increasing both the cost and time needed to return a vehicle to the road.

Regulators have also raised concerns about transparency. A review by the Australian Securities and Investments Commission found that many insurers provided customers with only general explanations for premium increases. Consumers may therefore find it difficult to understand precisely why their policies have become more expensive or which factors have influenced the final price.

The federal government has called for fairer pricing and clearer information for customers. It has committed A$2.4 million to reforms intended to improve transparency in insurance pricing, although the initial focus is on home and contents insurance. The government is also considering whether greater transparency measures should be extended to motor insurance.

For motorists, comparing policies at renewal may help identify more affordable cover. Customers can check whether their vehicle's insured value is accurate, review their estimated annual kilometres, compare excess options and confirm that everyone listed on the policy still needs to be included. Reviewing alternative insurers before accepting a renewal offer may also reveal better value.

However, drivers should compare policy benefits, exclusions, excess payments and coverage limits alongside the premium itself. A cheaper policy may not provide equivalent protection.

The continuing rise in premiums highlights a broader challenge for Australian households: balancing essential insurance protection against increasing living costs. Greater pricing transparency, competition between insurers and efforts to address repair-sector shortages could help consumers better understand their options. The impact of future reforms will depend on how insurers respond and whether savings from improved practices translate into more affordable policies.
