Best Business Bank Accounts Australia 2026: Fees, Features & Free Options

Most Australian small business owners are paying too much for their business bank account — or leaving money on the table by staying with a legacy bank out of habit. In 2026, the gap between the best and worst options is significant. We've compared 8 accounts on fees, features, and real-world usability so you can stop paying for nothing.

The Short Answer

• Best overall: Zeller Transaction Account — $0/month, unlimited cards, Xero integration, invoicing built in
• Best big bank: CommBank Business Transaction Account — $0 base option, widest branch network, award-winning app
• Best for international payments: Airwallex — multi-currency accounts, $0 fees if you meet deposit minimums
• Best for sole traders starting out: ANZ Business Essentials — $0/month, simple, no fuss
• Avoid if you hate fees: NAB Business Everyday ($10/month) and Suncorp Business Everyday ($15/month) charge monthly fees with limited upside

Quick Comparison Table

*Airwallex waives monthly fee if you deposit ≥$5k/month or hold ≥$10k balance. Otherwise fees apply.

The Full Breakdown

1. Zeller Transaction Account — Best Overall

Zeller is the standout option for most Australian small businesses in 2026. It's not a bank — it's a regulated financial services provider — but it handles everything a business transaction account needs to, and does it better than the big banks for most SMEs.

Monthly fee: $0
Transactions: Unlimited free online transfers
Debit cards: Unlimited free Zeller Debit Cards — no per-card fees
Sub-accounts: Unlimited — create them in seconds online
Xero integration: Yes, bank feeds + invoices
Invoicing: Built-in invoicing system, no extra cost
Savings rate: Pair with a Zeller Business Savings Account to earn up to 4% p.a.
Support: Phone, email, SMS — 9am–1am AEST, 7 days a week
International fees: No international transaction fees (rare for this price)

The catch: no branches, no cash handling. If your business regularly deposits cash, Zeller isn't a fit. But for any business operating digitally — e-commerce, services, consulting, trades with card payments — it's the most capable free account in Australia right now.

Verdict: If you're not depositing cash daily, Zeller is almost certainly your best option. The combination of $0 fees, unlimited cards, built-in invoicing, and Xero integration at no cost is hard to beat.

2. Commonwealth Bank Business Transaction Account — Best Big Bank Option

CommBank is the most widely used business bank in Australia, and for good reason. Their business account comes in two modes: pay-as-you-go ($0/month) or fixed-fee ($10/month) — you can switch between them in NetBank any time.

$0/month option:
Electronic transactions: free
Staff-assisted transactions: $5 each
ATM withdrawals in AU: free
Best for: businesses that rarely need branch or teller services

$10/month option:
Electronic transactions: free
Staff-assisted transactions: 20 free per month, $5 each after
Best for: businesses that regularly make counter deposits or need teller help

App: Award-winning CommBank Business app — genuinely excellent
Branches: 500+ nationally
Xero integration: Yes via NetBank
International transactions: 3% fee (steep — use Airwallex if you pay international suppliers regularly)

Verdict: If you want the security and branch access of a major bank, CommBank's $0 base option is the one to take. Upgrade to $10/month only if you make regular counter transactions. Avoid it for international payments — that 3% fee adds up fast.

3. ANZ Business Essentials — Best Entry-Level Big Bank Account

ANZ's Business Essentials account is their entry-level offering and it's genuinely useful for sole traders and micro-businesses that don't make many transactions.

Monthly fee: $0
Electronic transactions: 20 free per month, $0.60 each after
In-person/teller transactions: $1.60 each
Debit card: ANZ Visa Debit
International fee: 3%
Overdraft: Not available on Essentials

The 20 free electronic transaction limit is fine for most small businesses that use BPAY and direct transfer for a handful of suppliers — but if you're running volume, you'll blow through it fast. At $0.60 per transaction over the limit, it adds up.

ANZ's Business Advantage account ($10/month) removes all transaction limits — that's the better pick if your transaction volume is higher.

Verdict: Solid for very small operations or businesses just starting out. Outgrow it quickly? Upgrade to Business Advantage or switch to Zeller.

4. Westpac Business One — Flexible Two-Tier Option

Westpac's Business One account is available in two tiers, and they've made the digital option genuinely competitive.

Business One (Digital) — $0/month:
Unlimited electronic transactions
No branch/teller transactions included
Best for online-only businesses

Business One (Plus) — $10/month:
Unlimited electronic transactions
Up to 25 assisted transactions per month
Branch access included

Westpac's app and internet banking are solid, and they have solid branch coverage nationally (though not as wide as CommBank). The $0 digital tier with unlimited electronic transactions is competitive — particularly versus ANZ Essentials' 20-transaction limit.

Verdict: Good mid-tier option. Digital tier beats ANZ Essentials on transaction volume; the Plus tier is comparable to CommBank's $10 option but with 25 (vs 20) assisted transactions.

5. Airwallex — Best for International Payments and E-Commerce

Airwallex isn't trying to be your local bank. It's built for businesses that deal in multiple currencies, pay international suppliers, or operate e-commerce across borders. In that context, it's exceptional.

Explore Plan — $0/month if: You deposit ≥$5,000/month OR maintain ≥$10,000 balance
Electronic transactions: Free
Multi-currency accounts: Hold and transact in AUD, USD, GBP, EUR, SGD and more
International transfers: Market-beating FX rates (typically 0.3–1% vs 3% at big banks)
Debit cards: Physical + unlimited virtual cards
Xero integration: Yes
No branch or cash handling

If you're importing goods, paying offshore contractors, running an international SaaS, or doing significant e-commerce, the 3% international transaction fee at CommBank/ANZ/Westpac is a business expense Airwallex eliminates almost entirely. On $50,000 of international transactions per year, that's $1,500 saved.

Verdict: For purely domestic businesses, Zeller beats it. For anyone dealing internationally, Airwallex is essential — and you might want both: Zeller for day-to-day, Airwallex for FX.

6. NAB Business Everyday — Pricier Without Clear Advantage

NAB's Business Everyday Account has historically been a mainstay for Australian businesses, but in 2026 it's hard to justify for most SMEs.

Monthly fee: $10/month
Electronic transactions: Free
In-person transactions: Limited free, fees apply above threshold
International fee: 3%
Xero integration: Yes

The issue with NAB is you're paying $10/month for a feature set that CommBank and Westpac offer at the same price with comparable — often better — digital experiences. For $10/month, CommBank at least gives you 20 free assisted transactions. NAB's digital experience has lagged behind CommBank's app in most independent reviews.

Verdict: Hard to recommend over CommBank or Westpac at the same price point, and significantly worse than Zeller for digital businesses. Skip unless you have a specific reason to bank with NAB (existing relationship, lending, etc.).

How to Choose: The Decision Framework

What to Look For Beyond the Monthly Fee

The monthly fee is often the smallest cost. Here's what actually matters:

Transaction Fees

A "$0/month" account can still cost you significantly if you're charged per-transaction. ANZ Business Essentials gives 20 free electronic transactions — fine for a consultant, brutal for a retailer making 200 supplier payments a month. Do the actual maths for your transaction volume before choosing.

International Transaction Fees

The big four banks (CommBank, ANZ, Westpac, NAB) all charge around 3% on international transactions. On $100,000 of annual international spending, that's $3,000 in fees. Airwallex or Wise Business can cut that to under $500. This is often the highest-value switch a business with any international exposure can make.

Accounting Software Integration

Xero bank feeds are standard across all major accounts now. But Zeller goes further with direct invoice and contact sync — saving reconciliation time if you're running Xero for invoicing.

Card Issuance

If you have employees, the ability to issue multiple debit cards without per-card fees matters. Zeller offers unlimited free cards. The big banks typically charge for additional cardholders or require them to be signatories — a compliance headache for small teams.

Cash Handling

If you have a physical retail or hospitality business handling significant cash, you need a big bank with branch access. Neobanks like Zeller and Airwallex don't offer this — full stop. Don't choose them if cash is part of your daily operation.

Do You Actually Need a Separate Business Account?

Yes. If you're running a registered business, a dedicated business account is not optional — it's a compliance requirement for GST-registered entities and makes BAS preparation significantly less painful. Even sole traders benefit from the separation: mixing personal and business transactions is an audit nightmare and slows down your accountant (which costs you money).

Opening a business account has also gotten fast. Zeller lets you open online in under 6 minutes for sole traders and single-director companies. CommBank and ANZ offer online applications for simpler business structures, with branch visits required for more complex setups (trusts, multiple directors).

The Bottom Line

For most Australian small businesses in 2026, the answer is Zeller for day-to-day banking. It's free, feature-rich, and designed for how modern businesses actually operate — not for how banks operated in 1995.

If you need a big bank for lending relationships, branch cash handling, or peace of mind from an APRA-regulated ADI, CommBank's $0 option is the best of the majors. Upgrade to $10/month only if you regularly use counter services.

And if you deal internationally at any meaningful scale, layer in Airwallex. The FX savings alone will pay for whatever setup time it takes.

The days of automatically handing over $15–29/month to a major bank for a basic business account are over. The alternatives are better.
