Short answer: the law doesn't require comprehensive insurance. In Australia, only compulsory third party (CTP) insurance is mandatory, and it's usually included with your registration. But if you're financing the car, your lender will almost always require comprehensive cover as a condition of the loan.
Why lenders insist on it
With a secured car loan, the car is the lender's security. If it's written off or stolen and you're uninsured, the lender's security disappears, but you still owe the loan. Comprehensive insurance protects both of you.
What lenders usually ask for
- Comprehensive cover in place from settlement. Many lenders won't release funds until they've seen a certificate of currency.
- The lender noted as an "interested party". Your insurer adds the lender to the policy so a total-loss payout goes to the lender first.
- Cover kept in place for the life of the loan. Some lenders check periodically.
CTP vs third party vs comprehensive
- CTP: covers injury to people. It doesn't cover damage to any car, yours or theirs.
- Third party property: covers damage you cause to other people's property, not your own car.
- Comprehensive: covers your car as well as others', including theft, fire, storm and accidents.
What about gap insurance?
If your car is written off, comprehensive insurance pays out its agreed or market value, which can be less than what you still owe, especially early in a long loan or one with a balloon. Gap cover pays the difference. It's optional. Compare it carefully and don't feel pressured to buy it at the dealership: you can often find it separately.
If your cover lapses
Letting comprehensive insurance lapse is usually a breach of your loan contract. Depending on the lender, it may contact you, ask for evidence of new cover or, in serious cases, treat it as a default. More importantly, if something happens while you're uninsured, you'll be paying off a car you no longer have.
Budget for it upfront
Insurance can be a significant cost, especially for younger drivers or performance cars. Get a quote before you commit to a car, and factor it into what you can afford alongside the loan repayment.
