Third party versus comprehensive is not a price question first. It is a risk question. Can you pay to repair or replace your own car, and can you pay if you damage someone else's?
Plenty of Australian guides stop at a three-row table and a quote button. The table is the easy part. The hard part is the crash where you are not at fault and the other driver has no property cover, the hailstorm with no other driver at all, the fire-and-theft cap that is lower than the car, and the renewal where the agreed value has quietly fallen. This article is about those gaps.
It is a cover-type guide. It does not rank insurers and it does not invent premiums. For dollar ranges by state, use how much car insurance costs in Australia, average prices by state. For how injury schemes differ, including green slips, read CTP vs third party vs comprehensive in Australia. That guide links back here for the optional-cover decision. This page links to it for the injury scheme. Read both. One policy does not do the other job.
More ownership context sits in the laws, registration and insurance section.
The short answer
Choose comprehensive if the car is financed, if a lender requires it, or if replacing it from savings would hurt. That includes many daily cars that are no longer new.
Choose third party property, or third party fire and theft, only if you could genuinely walk away from this car and you still want protection against the other person's repair bill.
Keep compulsory third party (CTP), or your state's equivalent, either way. It covers injuries to people. It does not fix cars, fences or shopfronts.
There is no single best comprehensive policy to name here. Features, excesses and prices move with the driver, the postcode, the car and the year. A named winner would be a made-up league table.
Why the names keep causing bad decisions
Australians use "third party" for two different products.
CTP is the injury policy you must have to register the car. In some states it is inside the registration charge. In others you buy it as a separate step. Public pages from insurers do not even describe that split the same way, which is why this article does not pretend to be the state-by-state scheme guide. Use the CTP guide and confirm the detail with the scheme in the state where the car is registered.
Third party property damage, often shortened to third party or TPPD, is optional. It is the policy that responds when your car damages someone else's vehicle or property. It is not CTP with a friendlier name. Buying comprehensive does not cancel the need for the injury scheme. Buying the injury scheme does not give you property cover.
A third label, third party fire and theft, sits in the middle. Some insurers sell it as its own policy. One published policy sells fire and theft as an option added to third party property, with the car's limit shown on the certificate rather than as one national cap. Read the product you are actually quoted.
What does third party car insurance cover?
In ordinary Australian use, third party car insurance means third party property damage.
It is built to pay for the legal liability that comes from damage your car causes to other people's vehicles or property. ASIC's Moneysmart site, updated 10 August 2026, describes it that way: it does not cover damage to your car, but it covers damage to other people's cars or property caused by your car. Many policies also pay reasonable legal costs if that liability is disputed. That legal-cost benefit is product-specific. Check the Product Disclosure Statement (PDS).
What a solid third party property policy is for:
The other driver's repair bill if you cause the crash.
Damage to other property: a fence, a gate, a parked trailer, a shopfront. Your own house is a different question. Damage to property you own is often a home-insurance claim, not a third party car claim. Unverified as a universal exclusion: confirm both PDSs before you rely on that split.
Legal liability up to the limit on the schedule, not up to whatever the repair happens to cost if the bill exceeds the limit.
What it is not for:
Repairs to your car when you are at fault.
Your car after hail, storm, flood or a tree branch, when there is no other driver.
Theft of your car, unless you have bought a fire-and-theft version.
Fire, unless that version is included.
Vandalism such as a keyed door or a smashed window, on a standard property-only policy.
Injuries. Those sit with the state injury scheme.
Mechanical failure, rust, wear and tyres that have simply worn out.
The uninsured-driver extra is not the same as comprehensive
Some third party policies pay a limited amount toward your own car if an uninsured driver is at fault and you can identify them. This is the clause people mistake for "I am covered either way".
It is not a market standard, and the caps differ:
Canstar's explainer, dated 22 April 2025, says this own-car benefit is often about $3,000 to $5,000, and that you may need to identify the other driver. That is a summary of the market, not a legal minimum.
One published third party property policy says it can help if an uninsured driver damages your car, up to $5,000, if the insurer agrees the other driver was at fault and you provide their name, address and registration. The same insurer's fire-and-theft policy has a similar uninsured-driver limit.
Another published third party policy says the insurer will pay the reasonable repair cost up to $5,000, or if the car is a total loss, the lesser of $5,000 or market value.
A $5,000 cap does not restore a $15,000 car. It also usually demands that you identify the other driver. A hit and run, a driver who gives a false name, or a dispute about who was at fault can leave the benefit unpaid. These figures are the insurers' published product summaries, reviewed on 5 October 2026, not a line-by-line reading of each PDS. The schedule and the PDS win.
Liability limits are large, and still not infinite
Published policy examples reviewed for this guide describe liability cover of up to $20 million on one third party property policy, up to $30 million on a second and up to $20 million on a third. The pattern is a multi-million-dollar liability limit, not a small repair allowance. The exact number is the insurer's, and it is there because hitting a late-model car, or several of them, or a building, can be very expensive.
Moneysmart's teaching example is the right scale to remember. Nathan keeps only CTP because his car is old. He hits a new sports car. The repair is $20,000. With no property policy, he borrows $20,000 and works extra hours for five years. That $20,000 is a teaching figure, not a quote and not a typical premium.
Third party property exists so that bill is the insurer's problem up to the policy limit, after any excess, instead of yours.
What third party fire and theft adds, and what it still leaves out
Moneysmart describes this level as third party property plus cover for your car if it is stolen or damaged by fire.
That is the idea. The contract is narrower than the label suggests.
One published third party fire and theft policy says it can cover theft or fire up to $10,000, and that this own-car benefit is for fire, theft and attempted theft, not for a crash. Another published fire-and-theft option pays up to the amount on the certificate of insurance, or market value if the car is a total loss, whichever is lower. One insurer publishes a round cap. Another publishes "whatever the certificate says, and not more than market value". Comparing them on the premium alone is meaningless.
Fire and theft still will not usually pay for:
Your own crash damage, including when you are at fault.
Hail, storm or flood.
Malicious damage that is not a theft or a fire.
A windscreen cracked by a stone.
It can be the right middle step for a modest, paid-off runabout if the car limit is close to what the car is worth and you would not repair crash damage anyway. A $10,000 theft cap on a car you could not replace for $10,000 is not full cover. It is a contribution.
The second of those published options also mentions a hire car for up to 14 days after theft or attempted theft, plus towing and storage after fire or theft, and replacement of child seats damaged in those events. The first published policy does not describe that same bundle on the page reviewed here. Extras do not travel with the product name. If the hire car, the child seat or the towing is why you are buying the policy, find the sentence in the PDS.
What comprehensive car insurance covers
Moneysmart's description is the clean one. Comprehensive cover protects your car and other people's cars or property, even if you caused the accident. It also typically covers theft, fire and weather. It will not cover everything. Exclusions, excesses and the PDS decide the claim.
In practice, a mainstream comprehensive policy is the one that can respond to:
Accident damage to your car, at fault or not, subject to excess and exclusions.
The same third party property liability that a third party policy covers, so you do not need a second property policy on top.
Theft and attempted theft.
Fire.
Many weather events, often including storm and hail. Flood is less consistent. Some policies limit it, delay it, or apply an embargo when a known storm is coming. One published policy says it may not cover some severe weather during an embargo period, and that the insurer will tell you if an embargo applies when you buy. That is one insurer's wording, not every insurer's.
Malicious damage, on many policies. Wording differs. Intentional damage by you, or by someone you invited to do it, is a common exclusion. A stranger keying the door is not the same event as you damaging the car.
Comprehensive is also where agreed value becomes a real choice. Third party fire and theft, when it covers the car at all, is more often tied to a cap or to market value. Canstar notes that agreed value is a comprehensive feature and that third party own-car benefits, where they exist, may only follow market value. Confirm the quote in front of you. Unverified as a rule that no third party policy in Australia offers agreed value. It is uncommon, not a statute.
Benefits that sound standard and are not
Insurer pages pile on extras. Treat each as optional until the schedule says it is included.
New-car replacement. One published policy example offers a new replacement on its standard and upgraded comprehensive tiers only if the car is under 3.5 tonnes, was bought as a new or demonstrator vehicle, and is under 24 months old on the standard tier or under 36 months on the upgraded tier. Its entry-level comprehensive tier does not include it. Another insurer's age and kilometre cut-off will differ. The comparison table in that April 2025 research article shows some policies using 24 months or 40,000 km, and one using 36 months or 60,000 km. Those are product rows, not a national rule.
Hire car after a claim. Sometimes included, sometimes an extra, sometimes capped by days or by dollars.
Choice of repairer. Some policies let you choose. One published policy's fire-and-theft repairs, and its uninsured-driver repairs, use a repairer the insurer chooses. Do not assume a comprehensive policy is a free choice of workshop.
Windscreen. One published policy example makes excess-free glass an optional extra, or includes it on its upgraded comprehensive tier. A stone chip is not automatically a free claim.
Personal items, baby seats, towing, emergency accommodation, roadside assist. Each has a limit and a trigger. Roadside assist sold inside the policy can overlap a separate roadside membership you already pay for.
Any-driver cover. Common, and still subject to undisclosed-driver excesses and to use the policy never agreed to.
Dealer add-ons are a separate product again. Moneysmart warns that tyre-and-rim insurance and similar dealership extras can be hard to claim on, or expensive compared with paying for the repair yourself. Do not let one of those replace a decision about comprehensive cover.
The difference between comprehensive and third party car insurance
The difference is whose car the policy will pay to repair, and which events count.
Third party property pays for other people's cars and property when you are liable. Comprehensive pays for that and, usually, for your own car after a crash, a theft, a fire or listed weather. Fire and theft is third party property plus a limited own-car benefit for fire and theft only.
CTP is not in this comparison as a substitute. It is the injury layer underneath all of them.
Event | CTP or local injury scheme | Third party property | Third party fire and theft | Comprehensive |
|---|---|---|---|---|
Injuries to other people | Yes, under that state's rules | No | No | No. You still need the injury scheme |
Damage you cause to another car or to someone else's property | No | Yes, up to the liability limit | Yes, up to the liability limit | Yes, up to the liability limit |
Your car, you at fault in a crash | No | No | No | Usually yes, excess applies |
Your car, other driver at fault and insured | No. You claim on their property policy | Not your policy. You claim on theirs | Same | You can usually claim on yours. The insurer may recover from theirs |
Your car, other driver at fault and uninsured or unidentified | No | Sometimes a capped benefit if you can identify them | Sometimes, same cap problem | Usually yes, if the crash is an insured event |
Theft or attempted theft of your car | No | No | Yes, often capped or limited to the certificate | Usually yes, up to agreed or market value |
Fire | No | No | Yes, with the same car limit | Usually yes |
Hail, storm, flood | No | No | Generally no | Often yes for storm and hail. Flood varies. Embargoes exist |
Vandalism that is not theft or fire | No | No | Generally no | Commonly yes. Read the malicious-damage wording |
Mechanical failure, rust, wear and tear | No | No | No | No |
Replaces CTP | It is CTP | No | No | No |
Every "usually" and "often" in that table is deliberate. Two policies with the same name are not the same contract. If a cell matters to you, find it in the PDS before you buy.
Is comprehensive car insurance worth it?
Sometimes yes. Sometimes it is a poor trade. The honest test uses your car and your quotes, not a national average.
Moneysmart's own questions are the right starting list:
Can you afford to be without this car if it is damaged, stolen or written off?
Can you repair or replace it without insurance?
Can you pay for other cars or property you damage?
Is it parked on the street, or somewhere theft and vandalism are more likely?
Is there a loan, and could you repay that loan while also paying for another car?
Do you want a known payout figure if it is written off?
If it is financed, does the lender require a minimum level of cover?
Work through them in order.
The lender's rule beats your preference. If the finance contract requires comprehensive insurance, third party is not a clever saving. It can be a breach of the loan. A write-off without comprehensive can leave the debt in place and the car gone. The payout, if you do have comprehensive, is the agreed or market value minus the excess and any other deductions in the PDS. That figure can be less than the amount you still owe, because cars often fall in value faster than the loan. Unverified: this article does not quote a gap-insurance market or a typical shortfall. Ask the lender what the contract requires, and ask the insurer what a total-loss payment would be based on this year's sum insured.
Your only car is a different test from a second car. Moneysmart's Lisa scenario is the point. She drops from comprehensive to third party property because the renewal looks expensive. She hits another car on the way to work. That driver has only CTP, so there is no property insurer to claim against for her own damage. Her third party policy does not fix her car. She cannot afford the repair and loses the job because she cannot get to work. Lisa is an illustration, not a case file. The mechanism is real: third party does not become comprehensive just because the crash wrecks your week.
"I am a careful driver" does not answer hail, theft or a parked car. Comprehensive is not only an at-fault product. A storm, a shopping-centre dent with no note on the windscreen, or a theft from the street never asks whether you caused it. Third party property pays none of those for your car. Fire and theft pays only the fire and the theft, and only up to its car limit.
A low-value car can still justify comprehensive, and an expensive premium can make it a bad buy. Some comparison articles push a rule of thumb that comprehensive stops being worth it when the year's premium is more than about 10 percent of the car's value. Unverified. That figure showed up in secondary guides during research for this page. It is not a Moneysmart or ASIC test, and this article does not adopt it. Do the sum yourself with real quotes. Take the annual premium difference between comprehensive and the third party policy you would actually buy, with the same excess. Compare that gap with what you would lose if the car were written off tomorrow, and with whether you could get to work without it. A few hundred dollars of extra premium can be rational on an $8,000 car you cannot replace. It can be irrational on a $3,000 car you have already decided not to repair, if the liability policy underneath is solid.
Worth it is not the same as "the dearest policy". A comprehensive policy with an excess you cannot pay, a market value you have not checked, and an exclusion for the way you really use the car is not worth more than a cheaper contract you have read. Fit beats the badge.
Get the premium half of this decision from average car insurance prices by state. Do not paste a mate's premium onto your car. Age, postcode, parking, kilometres and the model move the price by more than the state average does.
Who should choose which cover
Financed or near-new daily car. Comprehensive. Assume the lender will require it until the contract says otherwise. Agreed value can matter in the first years, and you should re-read that agreed figure at every renewal, not just the premium. If you are still choosing the car, fold insurance into the running-cost sum in cheapest cars to run in Australia and the purchase comparison in new versus used, full cost in 2026. A sharp drive-away price is not the full cost. Drive-away price versus list price explains the on-road slice. Insurance sits beside it, not inside it.
Paid-off old car, and you would scrap it after a serious crash. Third party property is rational if you can also cope with hail and theft. If the car is still worth enough that a theft would sting, price fire and theft against comprehensive and compare the car limit, not just the premium. A cheap car from the lowest-priced new models is not automatically a third party car once it is a few years old. The test is replacement money, not the original sticker.
One modest car, street parked, in a hail-prone or high-theft area. Look hard at comprehensive even if the market value is modest. Fire and theft does not pay for hail. The saving disappears the first time a storm writes the car off and you still need to get to work. This is a judgement about your suburb and your fallback transport, not a premium table.
P-platers and other young drivers. Young drivers often pay more because claim frequency is higher. The cover type still follows the car and the shock you can absorb. An old first car can suit third party if the household can replace it. A financed or newer car points back to comprehensive. Insurers also add excesses for age, experience or drivers who are not listed. This article will not invent those dollar amounts. Add every excess on the quote before you treat a low premium as affordable. For the car side of that decision, see best first cars for P-platers in 2026.
Rideshare, delivery or other paid use. Many personal policies exclude carrying passengers for a fare, food delivery, or other business use unless you have declared it and the insurer has agreed. Canstar's target-market note makes the same warning: not every policy covers rideshare, taxi work or delivery. Unverified as "all insurers exclude it". Some will cover occasional rideshare and refuse full-time work. If the use is not on the schedule, assume a claim will be fought.
A household that already has another way to travel. Third party property, or fire and theft with a realistic cap, can be enough for a second car that is not needed for work or school. It is a weaker fit for the only car in a household with no realistic backup.
Insurance is one line in a larger ownership bill. Hidden costs of owning a car, car service costs in 2026 and petrol versus hybrid versus electric running costs are the neighbouring sums. Model choice changes the insurance quote. Average new car prices by brand is useful context for what "expensive to replace" means on a new car, not a premium.
Agreed value, market value, and the renewal trap
Moneysmart sets the definitions out plainly.
Agreed value is a fixed amount you and the insurer set. You know the total-loss figure. As the car ages, the insurer may reduce that amount each year. You usually pay more for an agreed-value policy than for market value.
Market value is what the insurer assesses the car would have sold for at the time of the claim, using industry data. It is not the price you hope to get privately, and it is not a trade-in figure you have in your head. You do not know the payout in advance, and you cannot set it.
Melanie's Moneysmart scenario is the trap. She insures a new car for an agreed $18,000 because she wants the full replacement cost. She renews for five years without reading the schedule. After a write-off, the insurer pays $8,000. The agreed value has stepped down each year while the premium has not behaved the way she expected. She cannot find a matching used car for $8,000 and puts in another $2,000. Those dollars are a teaching example, so you can see the mechanism. They are not a prediction for your car.
At each renewal, read three numbers before you read the marketing: the sum insured, the basic excess, and the list of drivers. A lower premium that was achieved by cutting the agreed value is not a saving if the new figure will not replace the car.
What actually happens after a crash
You are at fault. Third party property can deal with the other party's car and property, after the excess. Your panel beating is yours. Comprehensive can deal with both, after the excess, unless an exclusion applies. Drink or drug affected driving, an unlicensed driver, or use you never declared are the exclusions that turn a paid policy into a refused claim. Do not guess where the line is. Read it.
The other driver is at fault and insured. You can claim on their property policy whether or not you have comprehensive cover. That path can be slow. Fault can be disputed. Their insurer can ask for more than one quote. While that argument runs, a third party policy of your own will not usually put your car back on the road. Comprehensive often will, and your insurer then seeks recovery. You may pay your excess and have it refunded if recovery succeeds. Refund rules differ. Unverified as a promise that every insurer returns the excess. Ask before you lodge.
The other driver is at fault and has only CTP, or leaves the scene. This is where third party policies are weakest. Your own repairs depend on a capped uninsured-driver benefit, if the policy has one, and on you identifying them. Comprehensive is the cover that is built for this outcome. Lisa's scenario is this outcome with the added twist that she caused the crash. The hit-and-run version is harder, because there may be nobody to identify.
Nobody else is involved. Hail, flood, a falling branch, a theft, a fire in a car park. Third party property does not respond to your car. Fire and theft responds only to fire and theft. Comprehensive is the policy that might. "Might" is doing work: flood wording and storm embargoes are real limits.
You hit several cars, or something that is not a car. Liability limits in the tens of millions, on the products cited above, exist for this. A policy with a surprisingly low liability limit is a false economy. Compare the limit, not just the annual price.
One published insurer claims guide says not to admit fault or liability at the scene, to collect names, registrations and witnesses, and to contact the insurer rather than negotiate the repair yourself. That is one insurer's instruction, and it is sound general practice. It is not legal advice for a serious injury crash. Injury claims follow the state scheme described in the CTP guide.
Price, without invented premiums
This page will not tell you that comprehensive "costs about" any dollar figure. A number published for a 35-year-old in one capital, on one comparison site, is not your premium. Using it as if it were is how people decide the wrong cover.
What can be said from primary sources, with the dates attached:
ASIC media release 26-189MR, August 2026, on Report 838: motor premiums rose 8 percent in the 12 months to July 2025, after growth of more than 42 percent between 2019 and 2024. ASIC's footnote attributes those premium-growth figures to CHOICE (March 2026) and the Insurance Council of Australia (March 2025). The review covered eight brands and about 72 percent of the market. None of the insurers reviewed explained, in the quote or renewal documents, the key factors that set the premium or why it had changed.
Moneysmart, citing ASIC research: 74 percent of consumers who received a renewal in the previous 12 months were quoted a higher premium than the year before.
ASIC: 67 percent of consumers renewed the same type of policy with the same insurer. Of those, 40 percent did not contact the insurer or compare quotes first. The shorter line "40 percent of all drivers do not shop around" is looser than what ASIC wrote. Use the precise version.
ASIC: of consumers who contacted their insurer before renewing, 31 percent had the premium reduced without a cut to cover. Moneysmart's phrase is that almost one third who asked got a lower premium without reducing cover.
ASIC: where insurers charge more for paying by instalments, the gap versus paying annually was often in a 10 to 20 percent range, and renewal notices did not always make the annual saving clear. Moneysmart says paying by instalments could cost 10 to 20 percent more over the year. ASIC also reported that 54 percent of consumers did not know this or missed it. It is not a claim that every insurer adds a loading. It is a claim that many do, and that the dollar gap should be on the renewal.
ASIC: 37 percent of consumers named price as the most important factor when buying or renewing. Price is a fair priority. It is a bad priority if the cheaper policy deletes the event you are most exposed to.
Your price moves with age, licence history, claims, postcode, where the car sleeps, the make and model, modifications, kilometres, listed drivers, business or rideshare use, the excess, agreed versus market value, and optional extras. State averages and worked examples belong on the cost-by-state guide. Use them as context, then get at least three quotes on your own details.
A rational money test, with no invented premium:
Estimate what it would cost this month to replace the car with something you would actually drive, and note any loan still owing.
Get comprehensive and third party quotes on the same excess, the same drivers and the same declared use. If you are considering fire and theft, get that quote too, and write down the car limit next to the premium.
Subtract. The gap between those annual prices is the real cost of the extra cover. Not a national average.
Choose third party only if you can absorb the loss of your own car, including hail and theft if you did not buy fire and theft, and the liability limit on the third party quote is enough.
If you pay monthly, ask for the annual total in dollars. A smoother direct debit can cost more than it looks.
How to compare quotes so you are not comparing different products
Moneysmart's saving guide, also updated 10 August 2026, makes two points that quote sites bury.
The brand on the ad is not always the underwriter. The underwriter is the licensed insurer that pays the claim. The same underwriter can sell similar cover under different brand names at different prices. Check who the underwriter is, then check the PDS, not the logo.
Comparison sites are usually paid by the insurers they list. They do not show the whole market. One site is not a survey of every policy. The Insurance Council's Find an Insurer directory is a way to build a longer list. It is not a ranking and it is not a recommendation.
Line the quotes up on these points before you look at the annual price:
Cover level: comprehensive, fire and theft, or property only.
Agreed value or market value, and the agreed figure if there is one.
Basic excess, plus every other excess that could apply to the drivers in the household.
Liability limit.
Own-car limit, if the policy is fire and theft or an uninsured-driver benefit.
Flood, storm and hail wording, including any embargo.
Whether rideshare, delivery or commuting for work is accepted.
Repairer choice, parts policy and repair warranty.
Hire car: included or not, for which events, for how many days, and at what daily cap.
New-car replacement: age and kilometre limits.
Windscreen: excess or no excess.
What happens to the no-claim discount if you claim. The same guide says some policies charge less if you do not claim for a period. How far a claim moves next year's price is not standard. Ask.
Monthly total versus annual total, in dollars.
Discounts that expire after year one. An online discount or a new-customer discount can vanish at renewal. Multi-policy discounts can depend on the order you take policies out. The guide suggests asking the insurer about that order rather than assuming the website applied it.
Then read the exclusions. The checklist in that guide is the right one: mechanical failure, rust and wear; intentional damage; an unlicensed, drunk or drug-affected driver; and storm damage if the policy you are holding is not comprehensive. Add undeclared modifications and undeclared business use.
The same guide also notes that only 23 percent of consumers said they read the additional information guide, or the premium, excess and discounts guide, in full. The levers that change the price often live there, not on the renewal headline.
Five questions worth asking the current insurer, from that same guide:
Can you match or beat a competitor's quote for the same cover?
Are all the discounts I qualify for already on this renewal?
What happens to the price if the excess changes, and can I afford that excess in cash?
Which extras can come off without leaving a hole I care about?
Has anything in my profile changed: fewer kilometres, off-street parking, a driver who has left the policy, a car that is no longer used for work?
If the insurer will not move, that is useful information. Loyalty is not a cover type.
Exclusions and habits that make a cheap policy expensive
A refused claim is the most costly insurance you can buy. The patterns below are common. None of them is a substitute for the PDS on your quote.
Driving under the influence of alcohol or drugs, or letting someone else do it in your car.
A driver who is unlicensed, suspended, or outside the licence conditions.
A regular driver who was never listed, which may not void the policy but can add an excess large enough to make the repair pointless.
Business, rideshare or delivery use that the proposal never mentioned.
Modifications the insurer did not agree to.
Taking the car out in a known flood or during a storm embargo after the insurer has warned you.
Assuming a comprehensive policy repairs mechanical breakdown. It does not. A service schedule is a different bill. See service costs.
Letting the policy lapse for a week while you "shop around", then having the crash in the gap. Arrange the new policy to start before the old one ends.
Insuring the car for less than it would cost to replace because a lower sum insured trimmed the premium. That is underinsurance by choice.
A renewal habit worth more than another feature
ASIC's research says most people stay, many of those people do not compare, and a sizable minority of those who simply ask get a lower premium without cutting cover. The same research says the documents often do not explain why the price moved.
So the annual job is short:
Check the injury policy is current with registration. Comprehensive does not renew it for you.
Read the sum insured, the excess and the drivers.
Decide whether last year's cover level still matches the car. A car that has fallen in value might move from comprehensive to fire and theft. A car that has become the only way to get to a new job might move the other way. Do that on purpose, not because the renewal envelope looked large.
Get other quotes on the same settings.
Ask the current insurer the five questions above.
Check the annual-payment total against the instalment total.
Keep notes on what was changed. Next year's you will not remember.
Price was the top factor for 37 percent of people in ASIC's research. Cover is still the factor that matters on the day of the claim. Use price to choose among policies that pass the cover test, not to skip the test.
Bottom line
CTP, or the local injury scheme, covers people. It is compulsory. It does not repair cars or pay for someone else's fence. The state detail is in the CTP, third party and comprehensive guide.
Third party property protects you when your car damages other people's vehicles or property. It does not repair your crash damage, and it does not pay for hail or theft unless a separate benefit says so, usually with a cap.
Fire and theft adds a limited own-car benefit for fire and theft. Compare the cap with the car, not with the premium.
Comprehensive is the policy that can repair or replace your car as well as other people's property, including many at-fault crashes, thefts, fires and weather events, if the PDS includes them and you pay the excess.
Pick the layer that matches the loss you cannot absorb. Then compare at least three quotes, read the exclusions, and check the sum insured at every renewal. For what people actually pay by state, use car insurance costs in Australia. For the rest of the ownership bill, start with hidden costs and cheapest cars to run.
General information only. Not personal financial advice. Confirm cover, exclusions, excesses and price with the insurer, the PDS and, where a loan is involved, the finance contract. Confirm injury-scheme rules with the state regulator.

Published insurer product pages and FAQs for third party property, third party fire and theft, and comprehensive policies, reviewed 5 October 2026. They are cited as policy examples only, not as recommendations, so the insurers are not named.
Product limits above describe those public pages. They are not a PDS extract and they are not a market-wide cap. Premium dollar figures are intentionally absent.
