Comprehensive car insurance in Australia

A clear guide to comprehensive car insurance in Australia — what's typically included, what's commonly excluded, the optional extras worth knowing about, and when comprehensive may be worth comparing.

Comprehensive car insurance is the broadest standard cover in Australia. It's also the most variable — two policies that both call themselves "comprehensive" can have very different fine print. Knowing what to look for makes the comparison much faster.

If you're still working out which type of cover may suit, the car insurance hub sits comprehensive next to the other options.

What is comprehensive car insurance?

Comprehensive car insurance is an optional policy that typically covers both damage to your own car and damage your car causes to other people's property. The bundle usually includes accidental damage, theft, fire, vandalism, and certain weather events, with optional extras layered on top.

It sits at the top of the standard cover ladder above third party, third party fire and theft, and CTP. CTP — the only mandatory cover in Australia — handles injury to people; comprehensive deals with vehicle and property damage.

Key things to understand

• Comprehensive isn't all-encompassing. The name implies a broader scope than it actually has — exclusions still apply.
• Agreed value vs market value — most comprehensive policies offer one, the other, or both. Our explainer walks through the trade-offs.
• Excess structure varies. Beyond the standard excess, you may also pay an age-based excess, inexperienced driver excess, or specific claim type excess.
• Hire car after an accident may be standard, optional, or absent depending on the policy.
• Choice of repairer may or may not be included. It often matters more than people expect.
• The PDS and TMD beat the marketing copy. Two policies marketed identically can have different exclusions and benefit limits.

How to compare comprehensive policies

1. Lock in your inputs — same vehicle, same drivers, same excess level — before quoting. The car insurance quotes page covers what to keep constant.
2. Get matched quotes from at least three insurers, mixing major brands with at least one challenger.
3. Build a feature comparison. Premium · excess · sum insured method · hire car · windscreen · choice of repairer · key exclusions.
4. Quote a higher-excess version alongside the default. Sometimes the saving is significant; sometimes it isn't.
5. Read the PDS for your shortlist. Especially the "what is not covered" section.
6. Check the TMD to make sure the policy is designed for someone in your situation.

Common mistakes to avoid

• Assuming comprehensive means 'covers everything'. Exclusions still apply, and the differences between policies live there.
• Picking the lowest premium without checking what's been stripped out.
• Defaulting to market value on a long-held car when an agreed value would suit better.
• Stacking optional extras you may not use — see our cheap car insurance guide for cleaner ways to lower the price.
• Not declaring modifications, business use, or all regular drivers. All can give the insurer grounds to reduce or refuse a claim.

What affects comprehensive premiums

• Driver age and history. See car insurance for young drivers for the lower-experience end.
• Vehicle make, model, and year. Repair cost, theft frequency, and safety profile all weigh.
• Where you live and park. Postcode-level claims data is a meaningful input.
• Annual kilometres and use. Lower mileage and personal-only use generally rate better.
• Sum insured method. An agreed value above market value will usually cost more.
• Optional extras. Each one has a price.
