Unsecured vs secured business loan: what security buys you
Neither one means no risk. The real difference is what’s on the table, and what’s in the fine print if things don’t go to plan.
General information only
An unsecured business loan doesn’t put property up as collateral, but that doesn’t mean nothing does. Most contracts still carry a personal guarantee and often a caveat clause. A secured loan puts a specific asset or property behind the facility, which usually buys a larger amount and a better rate. The question isn’t really “secured or not”. It’s what you’re agreeing to either way.
What does “unsecured” mean in practice?
Unsecured business loans in Australia typically run from $5,000 up to $250,000, with some lenders stretching to $500,000 for the right profile on bank statement conduct alone. Nothing is registered against your property upfront. What the contract says if things go wrong is another matter.
Understanding that distinction before you sign is what protects you. It rarely shows up as “security” on the label. It shows up in the covenants.
Unsecured tops out around $500,000 for the right profile. Secured scales with whatever asset or property backs it.
You need a larger amount, or a better rate matters more
Property or asset security typically unlocks larger facilities and better pricing, since the lender’s risk is backed by something they can call on. Worth it if you have the asset to offer and the amount justifies it.
Speed matters, or you don’t want property on the table
Faster to arrange, no property registered against your home, and assessed on cash flow and trading history rather than what you own. The trade-off is a smaller ceiling and, usually, a higher rate.
| What matters | Unsecured | Secured |
|---|---|---|
| Amount range | $5,000 to $250,000 standard, up to $500,000 for the right profile | Scales up with the asset or property offered, into the millions |
| What’s on the table | Usually a personal guarantee, often a caveat clause | A registered claim over a specific asset or property |
| Speed | Often 24 to 48 hours once paperwork is in | Slower, valuation and registration take time |
| Pricing | Generally higher, you pay for the flexibility of no property | Generally lower, the lender’s risk is backed by the asset |
What does putting up security save you?
Less than you’d expect on paper, and far more than you’d expect in practice. The RBA’s business lending series for July 2026 puts small business loans outstanding at 7.46% p.a. against 6.98% p.a. for residentially secured small business lending. That’s a gap of just 48 basis points. Put one lender’s own secured and unsecured facilities side by side and that gap runs to roughly six percentage points.
| Published rate | Secured | Unsecured |
|---|---|---|
| CommBank business overdraft | From 8.75% p.a. variable | From 14.80% p.a. variable, to $250,000 |
| Line fee on both | 1.70% p.a. | 1.70% p.a. |
| Great Southern Bank, $10,000–$50,000 | Not published | 11.70% to 21.70% p.a. |
| Westpac | From 8.11% p.a. variable | Not published |
Rates as published on each lender’s own product pages, September 2026. The CommBank pair is the like-for-like: same product, same 1.70% line fee, security is the only variable that moves.
Those two numbers disagree for a reason. The RBA’s 48-point gap is an average across every small business loan outstanding in the country, and most of that book is already secured by property. It blends the secured and unsecured books together, so it tells you very little about what any one lender will charge you for going unsecured. CommBank’s own pair does tell you, and it’s 605 basis points, about twelve times the market-average gap.
That’s the number worth arguing about, and it’s why one lender’s policy is a poor place to end the conversation. A bank prices unsecured at 14.80% because that’s what its single credit policy permits. Across a panel the same profile can land a long way either side of that, depending on whose appetite it happens to fit. That’s the whole reason for comparing more than one.
Does “no security” actually mean no security?
No. Plenty of unsecured lenders build personal guarantees and caveat clauses into the contract. Default, or breach a covenant, and that clause gives the lender a claim on your personal property, even though nothing was registered when you signed. Read the covenants, not just the “unsecured” label.
We’re filming a segment with one of our lending partners on what they look for in an unsecured application versus a secured one, and where the real risk sits in each. Once it’s up, it’ll sit here.
Choose unsecured if
- You don’t want property registered against your home
- Speed matters more than the lowest possible rate
- The amount you need is under $250,000, or $500,000 for a strong profile
Choose secured if
- You need an amount above the unsecured ceiling
- You have a property or asset you’re comfortable offering
- The rate saving matters more than speed
When an ATO debt changes the calculation
If you have an ATO debt on your file, a major bank won’t approve you for finance of any kind while it’s there. Full stop. In that situation, some unsecured products end up cheaper than an ATO payment plan, and clearing that debt improves your position for every application after it. That’s a real case where “unsecured and more expensive” isn’t the right frame. More broadly, unsecured lending is best treated as a transitional product, not a permanent one. The aim over time is to build toward bank or near-bank pricing rather than staying on unsecured facilities indefinitely.
