Secured vs Unsecured Car Loans in Australia — Which One's Right for You?
Secured vs unsecured car loans in Australia explained in plain English. Learn the difference, compare pros and cons, and find out which loan type suits your situation.
When you start looking at car finance, you'll see two main types of loans thrown around: secured and unsecured. The names sound technical, but the idea is straightforward once you cut through the jargon. One uses the car as collateral — the lender can take it back if you stop paying. The other doesn't. That single difference changes the interest rate, the risk, and the flexibility. Here's how to figure out which one actually suits your situation.
What is a secured car loan?
A secured car loan means the car you're buying is used as security for the loan. If you stop making repayments, the lender has the right to repossess and sell the car to recover what you owe.
Because the lender has this fallback, secured loans usually come with lower interest rates. They're less risky for the lender, and that saving gets passed on to you.
Most car loans in Australia are secured. If you're buying a car from a dealership and using their finance, it's almost certainly a secured loan — the car itself is the collateral.
What is an unsecured car loan?
An unsecured car loan doesn't use the car (or anything else) as collateral. The lender is relying on your creditworthiness and income to feel confident you'll repay. If you default, they can't just take the car — they'd need to go through legal channels to recover the debt.
Because the lender is taking on more risk, unsecured loans typically come with higher interest rates. You're paying for the flexibility and the reduced risk to your vehicle.
Unsecured loans are less common for car purchases, but they're useful in specific situations — particularly if you're buying an older or cheaper car that a lender won't accept as security.
Secured vs unsecured — the key differences
| Feature | Secured | Unsecured |
|---|---|---|
| Collateral | Car is used as security | No collateral |
| Interest rate | Generally lower | Generally higher |
| Risk to car | Can be repossessed | Cannot be repossessed directly |
| Car age limits | Usually under 10-15 years old | No age restriction |
| Borrowing amount | Often higher limits | Typically lower limits |
| Approval speed | Slower (car must be valued) | Faster (no valuation needed) |
| Loan term | 1-7 years common | 1-5 years common |
Pros and cons of a secured car loan
Pros:
- Lower interest rates — sometimes significantly lower
- Higher borrowing limits available
- Longer loan terms, which can mean lower repayments
- Easier to get approved if you have average credit (the car backs you up)
Cons:
- The car can be repossessed if you default
- The lender may require comprehensive insurance as a condition
- Age and condition restrictions on the car — most lenders won't secure a loan on a car older than 10-15 years
- You don't fully "own" the car until the loan is paid off
Pros and cons of an unsecured car loan
Pros:
- No risk of repossession — the car isn't directly tied to the loan
- Can be used for older or cheaper cars that don't qualify for secured finance
- Faster approval process (no vehicle valuation needed)
- More flexibility — you can sell the car without needing lender approval
Cons:
- Higher interest rates — you're paying for the lender's extra risk
- Lower borrowing limits
- Shorter loan terms, which can mean higher repayments
- Harder to get approved with less-than-perfect credit
Which one should you choose?
For most people buying a car in Australia, a secured loan makes more sense. The lower interest rate means you pay less over the life of the loan, and if you're planning to keep the car for years, the repossession risk is low as long as you can afford the repayments.
An unsecured loan might be the better choice if:
- You're buying an older car that doesn't qualify for secured finance
- You want the flexibility to sell the car before the loan is paid off
- You're borrowing a smaller amount and the rate difference is minimal
- You're uncomfortable with the idea of the car being used as collateral
The real question isn't just "secured or unsecured" — it's "what's the total amount payable?" A lower rate on a longer term can still cost more than a higher rate on a shorter term. Always compare the total cost, not just the monthly repayment.

What happens if you default on a secured loan?
If you miss repayments on a secured car loan, the lender can repossess the car. In Australia, they generally need to give you written notice and an opportunity to fix the default before taking the vehicle, but the process can move quickly.
Once the car is repossessed, it's sold — often at auction, which may not cover the full loan amount. If the sale price doesn't cover what you owe, you're still liable for the shortfall. That's right: you can lose the car and still owe money.
If you're struggling with repayments, contact the lender early. Most will try to work out a hardship arrangement before resorting to repossession.

A practical example
Say you're borrowing $30,000 for a car over 5 years:
- Secured loan at 7.5%: ~$601/month, total repaid ~$36,060
- Unsecured loan at 11%: ~$652/month, total repaid ~$39,120
That's a difference of about $51/month and roughly $3,060 over the life of the loan. Not life-changing per month, but $3,060 is a holiday, a set of tyres every year for five years, or a decent chunk off the principal if you put it towards extra repayments instead.
The bigger the loan and the longer the term, the more the rate difference matters. On a $50,000 loan over 7 years, the gap can be $6,000+.
The smarter way to save on your car loan
Whether you go secured or unsecured, the biggest cost isn't the interest rate — it's the money you don't have a plan for. If your car loan repayments are eating into your ability to save, you're going to feel it when the rego, insurance, and servicing bills roll around.

Quick Answers
Can I get a secured car loan for a used car?
Yes, but most lenders have age limits. If the car is more than 10-15 years old at the end of the loan term, many lenders won't offer a secured loan. In that case, an unsecured personal loan may be your only option.
Is the interest on a car loan tax-deductible in Australia?
Generally no, if the car is for personal use. If you use the car for business purposes, a portion of the interest may be deductible. Speak to an accountant about your specific situation — this is one area where getting professional advice is worth it.
Can I pay off a secured car loan early?
Usually yes, but some lenders charge an early repayment fee or break cost. Check your loan contract for the specific terms before making extra repayments or paying the loan out early.
Can I sell a car that has a secured loan on it?
Yes, but you'll need to either pay out the loan from the sale proceeds or get the lender's approval to transfer the loan. With an unsecured loan, you have more flexibility to sell without lender involvement.
Which is cheaper — secured or unsecured?
Almost always secured, because the lower interest rate means a lower total amount payable. But the cheapest loan is the one you can comfortably repay — a slightly cheaper secured loan that stretches your budget is more expensive than a slightly pricier unsecured loan you can easily manage.
