When you make a car insurance claim, your insurer will request quotes for the necessary repairs from one or more authorised repairers. If the repair costs come close to, or even outweigh, the insured value of the car, your insurer may decide to 'write off' your car instead of authorising the repairs.
When a car is written off, its details are entered in the Written-Off Vehicle Register (provided it's less than 15 years old and weighs less than 4.5 tonnes). The insurer will usually then provide the owner with a payout or a replacement car, depending on your insurance policy. This may be a car of the same model, or the market or agreed value, depending on your level of cover.
New car replacement is available with Comprehensive and Comprehensive Plus if CGU accepts a claim.
To be eligible, your car must have been new or a demonstrator when purchased, weigh under 3.5 tonnes, and be less than 24 months old for Comprehensive or less than 36 months old for Comprehensive Plus at the time of the incident. New car replacement is not included with Comprehensive Basics and is subject to availability in Australia. Refer to the PDS for full details.
