Why Insurance Premiums Vary by Location in NSW

By the Editorial Team · Friday, October 30, 2026

CTP insurance premiums in New South Wales show significant variation based on vehicle registration location, with quotes for the same vehicle differing by over three times between Manly and Woy Woy. This disparity arises from insurers' risk assessments tied to traffic density and accident rates, prompting some drivers to change their registration to lower-cost areas and raising concerns about fairness.

In New South Wales, compulsory third party (CTP) insurance premiums can vary significantly depending on the vehicle owner’s location, a discrepancy illustrated by recent pricing differences between Manly and Woy Woy. A vehicle owner who compared insurance quotes on the government’s platform found a dramatic disparity: a Toyota HiLux registered in Woy Woy was quoted at $450, while the same vehicle registered in Manly carried a premium of $1,500.

This variance stems primarily from how insurers assess risk based on geographic factors. Manly falls within the Sydney Metropolitan region, where traffic density is higher and accident rates tend to be greater, leading to correspondingly higher base premiums for CTP insurance. In contrast, Woy Woy is classified within the Newcastle/Central Coast insurance region, which typically features lower premiums due to reduced traffic risks and fewer injury claims.

Insurance companies set premiums by analyzing data such as traffic volume, accident history, and injury claims in specific areas to estimate the likelihood of incidents involving insured vehicles. This risk-based pricing model means that drivers in metropolitan areas with busier roads and higher accident rates generally face steeper insurance costs than those in regional or less congested locations.

Some drivers have responded to these cost differences by changing their licence addresses to lower-premium regions, a practice which raises questions about fairness and regulatory oversight. However, insurers maintain that the algorithms used to determine premiums accurately reflect the risk profile associated with each geographic area.

For vehicle owners with multiple residences, the difference in insurance costs between urban and regional locations can be substantial and has become a factor in decisions about where to register their vehicles. While some may view the premium gap as disproportionate, insurers argue that it is a necessary adjustment to cover the varying levels of risk on different road networks across New South Wales.
