All forms of insurance are based on risk, so your car insurance premiums could change when you move house - even if you only happen to move one street over in the same suburb. The area you live in, where your car is parked at night, and the total distance you travel each year all influence your car insurance premium. But if you move to another state or territory, there are other factors to consider too, such as compulsory third-party insurance (CTP). Speak to your insurer ahead of your move to safeguard against claims being denied, or having your car insurance voided. You can also compare car insurance policies with iSelect and see if you can find a better deal.
