About Greenslips

Geographical Zones

Geographical zones, like vehicle classifications, is an important factor in determining CTP greenslip prices.

Goegraphical zones are allocated by State Insurance Regulatory Authority (SIRA) (previously the MAA) and are part of the Premiums Determination Guidelines issued by SIRA to the insurers each year. Insurers are required to set greenslip prices on the basis of the geographical zones set out in those guidelines.

NSW is divided into five geographic zones for the purpose of setting greenslip prices. Four postcodes are split between two zones.

Information on vehicle classifications is also available on this website.

The allocation of postcodes to zones is set out in the table below.
