The short verdict
No single bank is best for every business loan. As a category, the big four banks (CommBank, Westpac, NAB and ANZ) tend to suit established businesses with full financials, clean credit and property to offer. Regional and second-tier banks often suit local, mid-sized deals, challenger banks suit owners who want a mostly digital process, and customer-owned banks suit members who value a relationship. Choose the bank type that matches your file.

The best bank for business loans in Australia is the one whose lending rules your business already satisfies on the day you apply. Banks differ less in what they offer than in who they are set up to lend to: how long you have traded, what security you can provide and how much paperwork you can produce. This verdict compares the four main types of bank, not individual brands, so you can pick the door most likely to open.
What types of bank lend to Australian businesses?
Four broad types of bank lend to small and medium businesses, and each tends to suit a different kind of borrower.
- The big four banks (CommBank, Westpac, NAB and ANZ). We name them only as a category. Large national lenders like these tend to work from standardised credit policy, which suits businesses that fit the template neatly.
- Regional and second-tier banks. Smaller listed banks and banks with a regional base. They often know their home markets and industries well and may take a closer look at a local deal.
- Challenger and digital banks. Newer entrants that run much of the application online. They can suit owners who are comfortable uploading documents and connecting accounting software.
- Customer-owned banks. Credit unions, mutual banks and building societies owned by their members. Our credit union business loans verdict covers them in depth.
All four are authorised deposit-taking institutions. What separates them for a borrower is appetite, process and how much room there is for judgement.
How do the bank types compare?
We grade each type on the five tests we use across the site, for a typical small business borrowing between $100k and $1m.
| Test | Big four | Regional / second-tier | Challenger / digital | Customer-owned |
|---|---|---|---|---|
| Total cost for a strong file | Strong | Strong | Fair | Fair |
| Fit for a newer or unusual business | Weak | Fair | Fair | Fair |
| Security asked for | Fair | Fair | Fair | Fair |
| Flexibility on structure | Fair | Fair | Fair | Fair |
| Paperwork burden | Weak | Fair | Strong | Fair |
Read the grades as tendencies for the category, not promises about any one bank. A big bank can be the cheapest source of money in the country for a business that ticks every box, and a slow, frustrating one for a business that misses a single box.
Which bank is best for a small business loan?
The best bank for a small business loan depends on your profile more than on the bank. Match yourself to the row that fits.
| Your business | Bank type to try first | Why |
|---|---|---|
| Five-plus years of trading, profitable financials, property to offer | Big four or regional | Standard criteria suit a standard file |
| A local business in a regional centre with a strong community profile | Regional bank or customer-owned | Local knowledge can count for more |
| Two to three years of trading, comfortable doing everything online | Challenger or digital bank | Lighter process, quicker document handling |
| Already a member of a credit union with a long history there | Customer-owned | The relationship is part of the assessment |
| Under two years trading, a credit mark or an ATO debt | Probably not a bank yet | See non-bank business lenders |
Why do banks decline so many small business applications?
Banks decline when an application falls outside policy, and their policy is built for documented, lower-risk lending. When the Reserve Bank looked at small business conditions in October 2025, it found about one SME in five had hit problems getting finance, pointing to tough lender requirements, pricing that didn’t suit, slow processing and demands for collateral. Over the same period, non-bank lenders have won a growing share of SME borrowing since early 2022, most noticeably in smaller loans.
That doesn’t mean banks have stepped back. The Bulletin also reports banks have been focusing on growing business lending, which has added competition. It means banks are strongest where the file is strongest, and other lender types have filled the gaps.
What will a bank ask for?
Expect a full picture. The list of documents in the business.gov.au application guide is a fair preview, and banks usually want most of it:
- photo identification for every director and guarantor
- two years of financial statements and business tax returns
- recent BAS and bank statements
- a business plan or a short explanation of what the money is for, with forecasts for larger loans
- details of existing debts, leases and other commitments
- property details and a valuation if the loan is secured
Having this ready before you apply is the single biggest thing you control. If you’d like a specialist to tell you whether your file is bank-ready or better suited elsewhere, start a short enquiry here.
Our verdict on the best bank for business loans
Our verdict: pick the bank type that fits your file, then compare on total dollars
- Best for
- Big four and regional banks for established, profitable businesses with property and clean credit. Challenger banks for documented businesses that want a digital process. Customer-owned banks for loyal members.
- Not for
- Businesses under two years old, owners with recent credit marks or unpaid tax debt, or anyone facing a hard deadline the bank's process can't meet.
- Check before you sign
- The total repayable including every fee, what the security and any guarantee actually cover, review and covenant terms, and whether the bank subscribes to the Banking Code.
Does the Banking Code of Practice protect my business?
It can, if your bank subscribes and your business qualifies. The 2025 Banking Code of Practice took effect on 28 February 2025 and includes an expanded small business definition. The Australian Banking Association says the total credit threshold rose to $5 million, bringing an extra 10,000 businesses under the Code. Protections include simpler loan documents, limits on enforcement action and rules on how guarantees are taken, such as meeting the guarantor separately and giving them time before the guarantee is accepted. Check the ABA’s subscriber list to confirm a bank you’re considering has signed up.
If something goes wrong, the Australian Financial Complaints Authority handles complaints from small businesses with fewer than 100 employees at no cost. It cannot consider a complaint about a credit facility above $5 million.
Illustrative example: one business, three bank types
Illustrative only. A joinery business has traded for six years, owns its workshop and wants $400k to buy CNC equipment and fit out a second bay.
- A big four bank asks for two years of financials, management accounts, a valuation of the workshop and a cash-flow forecast. The process takes several weeks. Because the file is strong, its offer has the lowest total cost.
- A regional bank in the same town asks for much the same paperwork, takes a little less time and offers slightly more flexible terms on the fit-out portion.
- A challenger bank handles the application online with connected accounting software. Its offer is quick to arrive but the total cost is higher than the other two.
Verdict for this owner: the big four or regional offer, decided on total dollars repayable and the covenants attached. For the equipment component alone, asset finance is worth pricing as well.
How do you approach a bank for a business loan?
- Get your numbers current. Lodge outstanding BAS and tax returns and bring your bookkeeping up to date.
- Write down the purpose, amount and term. Banks lend for a reason; a clear one reads better than a round number.
- Ask your own bank first if your account history is strong. It can already see how you trade.
- Get a second quote from a different bank type. A regional or customer-owned bank may assess the same deal differently.
- Compare in dollars. Use the total cost comparer on each offer, then read the security and covenant terms line by line.
- Don’t spray applications. Several formal applications close together can each leave a credit enquiry on file.
What if the bank says no?
A bank decline isn’t the end of the road. It usually means the deal sits outside that bank’s policy, not that it can’t be funded. Our page on the best loan when the bank said no walks through the next steps, and bank or non-bank explains when a specialist lender is the better fit. Many owners borrow from a non-bank for a year or two and then refinance to a bank once the file improves.
Want to know which bank type fits your business?
You don’t need to guess, and you don’t need to read every page in our lender comparison hub first. Tell us what you need and how your business trades, and a specialist will tell you whether a bank, a non-bank or a property-secured option fits best. There’s no credit check at the enquiry stage, your details go to one person rather than a list of lenders, and honest answers on the form mean the match is right the first time.
Questions owners ask
Which bank is best for business loans in Australia?
There isn't one bank that wins for everyone. The big four banks, as a category, tend to suit established businesses with strong financials and property. Regional banks can suit local deals, challenger banks suit owners comfortable applying online, and customer-owned banks suit members who want a relationship. The best bank for you is the one whose lending rules your business already meets.
Is it easier to get a business loan from a smaller bank?
Sometimes. Smaller banks may be more willing to look at a deal that doesn't fit a standard template, particularly in their home region or industry focus. They still apply credit policy, still want evidence you can repay and still check your credit history, so a weak file is a weak file at any bank.
Should I get a business loan from my own bank?
Start there if your business account shows healthy, steady trading, because your bank can already see that history. It isn't automatically the cheapest or the best fit, though. Compare the total cost in dollars, the security asked for and the repayment terms against at least one other option before you accept.
Do banks lend to new businesses?
Banks generally prefer a couple of years of trading and lodged tax returns. A new business without that history often finds bank approval hard unless strong security or an experienced owner with a solid personal position sits behind the application. Non-bank lenders and property-secured options are common alternatives in the meantime.
What protections do I get borrowing from a bank?
Banks that subscribe to the 2025 Banking Code of Practice give eligible small business customers specific protections, including rules for how guarantees are taken. Eligible small businesses can also take complaints to AFCA for free, although credit facilities over $5 million fall outside its limit.
Why did the bank say no to my business loan?
Common reasons are a short trading history, losses or falling revenue in the latest financials, credit marks, tax debts, not enough security, or too much existing debt. Ask the bank what would need to change. Then fix it, or take the same deal to a lender type built for that situation.
