In New South Wales, each vehicle must be insured before it can be registered. It is often called a 'greenslip,' because of its colour. There are six licensed CTP insurers in New South Wales. Suncorp holds licences for GIO and AAMI and Allianz holds Allianz and CIC Allianz licences. The remaining two licences are held by QBE and NRMA Insurance (NRMA). APIA and Shannons and InsureMyRide insurance also supply CTP insurance licensed by GIO.
Police forces have the power to seize vehicles that do not have the necessary insurance in place, until the owner of the vehicle pays the fine and signs a new insurance policy. Driving without the necessary insurance for that vehicle is an offence that will be prosecuted by the police and will receive penalty. Same provision is applied when the vehicle is standing on a public road.
Under the cents-per-mile system, rewards for driving less are delivered automatically, without the need for administratively cumbersome and costly GPS technology. Uniform per-mile exposure measurement for the first time provides the basis for statistically valid rate classes. Insurer premium income automatically keeps pace with increases or decreases in driving activity, cutting back on resulting insurer demand for rate increases and preventing today's windfalls to insurers, when decreased driving activity lowers costs but not premiums.
If the younger driver is covering his own costs, it might be cheaper for him to take out his own policy but include one of the older, lower risk drivers from the household as a named driver (as long as the older drive will use the car). However, if the older driver is footing the bill for both policies, multi-car insurance may still work out cheaper.
