Australian drivers paid an average of 14% more for car insurance in 2025 than the year before, and premiums aren’t slowing down. If you’ve opened a renewal notice recently and felt that sting, you’re not alone. The good news? Saving money on car insurance doesn’t require cutting corners on your coverage. With the right approach, you can lower your premiums significantly while keeping the protection you actually need.
At National Cover, we help thousands of Australians find competitive motor insurance through smart pricing research and a genuine price-beat guarantee. Our ASIC-licensed analysts compare rates daily, so we know exactly where the savings are, and where insurers quietly overcharge. That hands-on experience is what shaped the tips in this guide.
Below, you’ll find six practical strategies to reduce your car insurance costs without leaving yourself exposed. Whether you drive a private vehicle, operate a rideshare, or manage a commercial fleet, these tips apply across the board. Let’s get into what actually works.
1. Get a fresh quote from National Cover
One of the fastest ways to start saving money on car insurance is to request a current quote from a specialist insurer rather than automatically accepting what your current provider sends at renewal. National Cover’s price-beat guarantee means if you bring a valid competitor’s quote, they’ll work to beat it, which creates real competitive pressure on your premium from the outset.
When this saves you the most
A fresh quote delivers the biggest gains when your policy is 12 months or older, when your personal circumstances have recently changed, or when shifts in the used car market have altered the value of your vehicle. Insurers reprice their books regularly, and staying loyal to one provider doesn’t mean you automatically benefit from those lower rates.
What to prepare before you request a quote
Have your current policy document and most recent renewal notice ready before you call or submit a request. You’ll also want to know your annual kilometre estimate, your vehicle’s make, model, year, and any modifications, plus the names and licence history of all listed drivers on the policy.
The more accurate your details upfront, the more precise your quote, and a precise quote is far harder for an insurer to adjust upward later.
What to compare so you keep cover strong
Match excess amounts, included benefits, and claim limits directly side by side rather than comparing annual premiums alone. A quote that looks $200 cheaper per year might quietly drop roadside assistance or reduce your agreed value, which costs you far more when you actually need to make a claim.
Red flags to avoid when switching
Watch out for policies with a cooling-off period shorter than 14 days, vague wording around exclusions, or providers that won’t supply a clear Product Disclosure Statement upfront. Switching mid-policy is straightforward, but always confirm your new cover is active before cancelling your existing policy to avoid any gap in protection.
2. Shop around at renewal and compare like for like
Your insurer knows that most policyholders renew without question, and they price accordingly. Shopping around at renewal is one of the most reliable ways of saving money on car insurance in Australia, particularly when you compare policies on equal terms.
Why loyalty can cost you in Australia
Australian insurers consistently offer their sharpest rates to new customers, not to long-standing ones. The Australian Competition and Consumer Commission has documented that loyal policyholders often pay significantly more than new customers holding identical cover at the same company.
Switching every one to two years, or using a competitor’s quote as leverage, consistently produces lower premiums without you having to sacrifice cover.
How to run a fair comparison in 15 minutes
Gather your current policy’s key details including cover type, excess, and listed benefits, then request two or three quotes using identical inputs. Most Australian insurers return online quotes within minutes, so a genuine side-by-side check rarely takes more than 15 minutes.
Which policy features change the price fastest
Three variables move the premium more than anything else:
- Excess amount (higher excess means lower premium)
- Agreed value versus market value (agreed value typically costs more)
- Optional add-ons such as windscreen cover or hire car access
Questions to ask insurers before you buy
Ask each insurer about repairer choice and claim response times before you commit. Confirming whether your premium is locked for 12 months also prevents unwelcome surprises mid-policy.
3. Raise your excess without setting yourself up to lose
Adjusting your excess is one of the quickest levers for saving money on car insurance, but it only works in your favour if you choose a figure you can realistically cover at short notice.
How excess choices affect your premium
Your basic excess is the amount you pay out of pocket when you lodge a claim. Insurers reward a higher nominated excess with a lower annual premium because you’re absorbing more of the financial risk yourself.
How to pick an excess you can actually afford
Set your excess at a level you could pay within a week without borrowing. A common trap is nominating a high excess to shrink the premium, then facing a real claim without that cash available.
If you couldn’t pay your excess tomorrow, lower it, even if that means paying slightly more each year.
How multiple excesses can stack on a claim
Many policies apply more than one excess on a single claim. An age excess, a listed driver excess, and your basic excess can all apply simultaneously, pushing your total out-of-pocket cost well beyond what you planned.
When a higher excess does not make sense
If your vehicle’s insured value is relatively low, a high excess eats into any payout significantly. Keeping your excess modest and targeting savings elsewhere makes more financial sense in those cases.
4. Align your kilometres and usage with how you drive
Many Australian insurers use your annual kilometre estimate and declared usage type as direct pricing inputs. Telling them you drive 5,000 km per year rather than 15,000 km can produce a noticeably lower premium, which makes accurate reporting one of the simplest ways of saving money on car insurance.
How insurers price distance and usage
Insurers treat higher annual kilometres as higher risk because more time on the road means more exposure to accidents. Declaring a business or rideshare usage also lifts your premium compared to private-only use, so matching your declaration to your actual driving pattern matters.
How to estimate your annual kilometres accurately
Check your vehicle’s odometer against a service record from 12 months ago to get a reliable figure. If you have no service history, most GPS navigation apps track cumulative distance over time and give you a workable estimate within a few minutes.
What happens if you understate your kilometres
Understating your kilometres is treated as a material misrepresentation and can lead your insurer to reduce or reject your claim entirely. The short-term premium saving is not worth voiding your cover at the worst possible moment.
Always round your kilometre estimate up slightly rather than down to stay on the safe side.
Ways to cut kilometres without losing mobility
Combining errands into single trips and using public transport for regular commutes genuinely reduces your annual distance. Fewer kilometres on record at your next renewal gives you a legitimate basis to negotiate a lower premium with your insurer.
5. Reduce risk signals insurers price heavily
Insurers assess dozens of risk signals tied to your vehicle, your location, and your daily habits. Reducing those signals is a direct approach to saving money on car insurance that most drivers overlook at renewal.
Park and store your car in a safer way
Where your car sits overnight is a significant pricing input. Moving from street parking to a locked garage or secure car park reduces your theft and weather exposure, and most insurers lower your premium to reflect that change.
Improve security and theft deterrence
Fitting an approved immobiliser or GPS tracker signals to your insurer that your vehicle is harder to steal and easier to recover. Check with your provider which specific security upgrades attract a documented discount before you spend money on hardware.
A factory-fitted immobiliser already helps, but adding a visible deterrent like a steering wheel lock reinforces the signal to both thieves and underwriters.
Tighten who drives and how often they drive
Every additional listed driver on your policy adds statistical risk. Removing drivers who rarely use the car and limiting the policy to named drivers with clean licence histories reduces the overall risk profile your insurer prices against you.
Choose a car that costs less to insure and repair
Vehicles with readily available parts and low labour costs consistently attract cheaper premiums. Before your next purchase, check the model’s repair profile, as high-performance or imported cars carry higher premiums due to parts scarcity and specialist repair requirements.
6. Trim extras and tune cover to your real needs
The structure of your policy matters just as much as the insurer you choose. Paying for features you never use quietly inflates your premium each year, and trimming those extras is one of the most direct methods of saving money on car insurance without weakening your core protection.
Drop or avoid add-ons that rarely pay back
Optional extras like windscreen-only cover, key replacement, and roadside assistance are useful for some drivers and unnecessary for others. Check what you already hold before adding anything. Common duplications include:
- Roadside assistance through your vehicle manufacturer’s warranty
- Roadside cover through an existing motoring club membership
Choose agreed value or market value for your situation
Agreed value locks in a fixed payout and typically costs more per year. Market value adjusts with depreciation and suits older vehicles with declining worth better than new or heavily modified cars.
Match your valuation method to your vehicle’s age and how much certainty you need from a payout.
Pay annually and check instalment fees
Most insurers charge instalment loading fees when you pay monthly, adding anywhere from 10% to 15% to your total annual cost. Paying your full premium upfront removes that loading entirely and is one of the simplest cost cuts available.
Ask for discounts and confirm eligibility
Ask directly about multi-policy discounts, low-mileage concessions, and loyalty pricing before you accept any quote. Insurers frequently offer these reductions but apply them only when you specifically request them at the time of purchase.
Put it into practice
Each of these six tips works on its own, but the biggest premium reductions come when you apply several of them together before your next renewal. Start by auditing what you currently pay and what your policy actually covers, then work through the list: check your excess, confirm your kilometre estimate, strip out unused add-ons, and tighten your listed drivers. Saving money on car insurance is rarely about one single change; it’s the combination of small, deliberate adjustments that adds up across a 12-month policy.
When you’re ready to put a number on those savings, the fastest next step is getting a quote from a specialist who prices competitively from the outset. Get a car insurance quote from National Cover and bring your current renewal notice along. National Cover’s price-beat guarantee means your existing quote becomes your starting point for negotiation, not the final word.
