How to Switch Car Insurance in Australia Without a Gap in Cover

Separate CTP from optional cover

This guide covers Australian personal motor insurance only, not commercial or fleet cover.

CTP covers injury to people and is tied to vehicle-registration arrangements that vary by state or territory. Third-party property covers damage to other people's property; third-party property, fire and theft adds limited protection for the insured car; comprehensive cover is broader but still has exclusions.

Changing an optional policy does not establish that the CTP attached to the vehicle or registration has changed correctly. Check the applicable state or territory registration route separately.

Compare the replacement policy

Match the vehicle, regular drivers, licence details, address and use. Compare insured events, exclusions, excess, agreed or market value, repair choice, hire car, roadside or other extras, premium and payment schedule.

Read the current PDS, any SPDS, current updates and the effective date before accepting the replacement. A quote summary does not override the policy documents, and a cheaper premium does not prove equivalent cover.

Put the new start before the old end

Confirm the new policy start before the old policy end, in writing. Check the exact date and time, payment acceptance and policy number before asking the old insurer to cancel; this sequence reduces gap risk but does not guarantee continuous cover or acceptance of a future claim.

If a claim, finance condition or vehicle change is in progress, ask both insurers how it affects commencement and cancellation. Do not assume the new insurer has ended the old policy.

Obtain the old policy result

Ask the old insurer to confirm the cancellation effective time, any remaining premium, claim effect, refund or fee in writing. The applicable policy, payment method, claim position and insurer process determine the account-specific result.

There is no universal cooling-off period, refund, fee or CTP process for every policy and jurisdiction. The General Insurance Code says a retail policy may allow cancellation and a refund; entitlement still depends on the policy, and broker arrangements can differ.

Keep evidence for both policies

Save the replacement schedule, PDS set, payment receipt, old cancellation confirmation and any refund calculation. If a cancellation or refund does not match the confirmed terms, use the insurer's complaint process and then the applicable external dispute route if needed.

This is general information, not personal insurance, legal or financial advice.

SubsCraft tip: Record the new start time, old end time, CTP check, policy documents and cancellation result separately so a gap or duplicate premium is visible.
