TL;DR — Cheapest Business Banking Options for Australian Startups (2026)
Australian startups have two paths for business banking. Fintech-first: Airwallex (AUD 0/month Core) handles international payments at mid-market FX rates; pair it with a free traditional bank account for domestic BPay and payroll. Traditional-only: NAB offers the cheapest Big Four business account at AUD 0/month with no minimum deposits, while CommBank’s Business Transaction Account starts at AUD 0/month but limits free transactions. The optimal setup for most startups costs AUD 0/month: Airwallex for international + NAB for domestic.
Why Startups Lose Money on the Wrong Bank Account
Australian business bank accounts charge fees in three places: monthly account maintenance (AUD 0–40), per-transaction fees (AUD 0.30–0.60 per electronic payment), and foreign exchange margin (3–5% hidden in the rate). For a purely domestic startup processing 50 transactions a month through CommBank, the cost might be AUD 15–20/month in transaction fees — tolerable. The moment an international transaction enters the workflow, the FX margin eclipses everything else.
A startup paying a USD 2,000/month SaaS subscription (Stripe billing, GitHub Enterprise, HubSpot) through a traditional bank account loses roughly AUD 90–150/month in hidden FX spread — more than the startup’s total domestic banking costs combined. This is the argument for splitting banking into two layers: domestic (traditional, cheap) and international (fintech, mid-market FX).
Best Business Bank Accounts for Australian Startups Compared
| Provider | Monthly Fee | FX Rate | Local AUD Transfers | Multi-Currency | BPay | Best For |
|---|---|---|---|---|---|---|
| NAB Business Transaction Account | AUD 0 | Mid-market + 3–5% | Free (NAB app/Internet Banking) | Separate foreign currency account (AUD 10/month) | Yes | Domestic startups wanting a free Big Four account |
| CommBank Business Transaction Account | AUD 0 (with AUD 2,000/month deposit) | Mid-market + 3–5% | AUD 0.30/transaction | Not built-in | Yes | Startups already in the CommBank ecosystem |
| Airwallex Core | USD 0 | Mid-market (~0.3% markup) | AUD 0 | 12+ local currencies | No | Startups with any international activity |
| Wise Business | AUD 0 (+$31 setup) | Mid-market + ~0.43% | AUD 0 (PayID) | 9 local currencies | No | Freelancers and solo founders billing overseas |
| Revolut Business Basic | AUD 0 | Mid-market (weekdays, up to AUD 15,000/month) | AUD 0 | 25+ currencies (limited local details) | No | Teams needing multi-currency corporate cards |
| ANZ Business Advantage | AUD 0 (first 12 months, then AUD 10/month) | Mid-market + 3–5% | Free (unlimited) | Separate account (AUD 10/month) | Yes | Startups wanting unlimited free transactions |
All pricing verified as of May 2026. Transaction fees for Big Four banks are based on electronic payments — branch-assisted and cheque transactions cost more.
1. NAB Business Transaction Account — Cheapest Big Four Option
NAB offers a genuinely free business transaction account with no monthly fee, no minimum deposit, and free electronic transactions through NAB Internet Banking and the NAB app. Branch deposits and staff-assisted transactions cost AUD 1.50–3.00, but for a startup running payroll through the app and paying suppliers via direct debit, the ongoing cost is AUD 0.
The account comes with BPay, direct debit, PayID (Osko for instant AUD transfers), and a Visa Debit card for business purchases. NAB Connect, the online business banking platform, supports multi-user access with role-based permissions — useful once you have a bookkeeper or finance team member who needs view-only access.
The limitation: international payments still go through NAB’s standard FX desk with a 3–5% margin. For startups processing international payments, pair NAB with Airwallex or Wise — domestic through NAB, international through the fintech layer.

2. CommBank Business Transaction Account — Best for the Existing Ecosystem
CommBank waives the monthly AUD 10 fee if you deposit at least AUD 2,000/month — trivial for any operating startup. Electronic transactions cost AUD 0.30 each, with the first 20 free per month. If your startup processes 80 transactions a month, expect roughly AUD 18 in transaction fees (60 chargeable × AUD 0.30).
CommBank’s app consistently ranks as the best banking app in Australia. The business version supports invoicing, expense categorisation, and integration with CommBank’s EFTPOS terminals — useful if you run a retail or hospitality startup. NetBank’s multi-user access is more polished than NAB Connect for smaller teams.
Same FX limitation as all Big Four banks: international transfers carry a hidden 3–5% margin. For startups with international activity, the CommBank + Airwallex pairing works the same way as NAB + Airwallex.
3. Airwallex Core — The Free International Banking Layer
Airwallex provides a BSB and AUD account number (issued through its partnership with a local Australian bank) plus local receiving accounts in 12+ countries. The Core plan costs USD 0/month and includes:
- Mid-market FX with 0–0.3% markup depending on volume
- Batch payments to 1,000+ recipients via CSV upload
- Virtual Borderless Cards (free, instant)
- Xero integration (manual on Core, auto-sync on Grow)
- API access for custom payment workflows
The AUD account handles domestic transfers — payroll, supplier payments, ATO — but Airwallex does not support BPay. If your business pays ATO via BPay or needs to pay Australian suppliers who only accept BPay, you need a traditional bank account alongside Airwallex. The two-account setup covers the gap at zero monthly cost.
4. Wise Business — Best for Freelancers and Solo Founders
Wise charges a one-time AUD 31 setup fee and no monthly fee. The account provides local receiving details in 9 currencies — fewer than Airwallex but covering the key corridors (AUD, USD, GBP, EUR, NZD, SGD). For a solo founder billing US or UK clients, Wise is the cheapest all-in-one option: receive client payments via local bank details (free), convert to AUD at mid-market (0.43% fee), transfer to your Australian bank account (PayID, free).
Wise does not support BPay, batch payments are less polished than Airwallex, and there is no API access without additional setup. For a one-person startup sending 3–5 invoices per month internationally, these limitations barely matter. The AUD 31 setup fee is the only cost in year one.
5. Revolut Business Basic — Free Corporate Cards with Multi-Currency Spend
Revolut’s standout feature is the multi-currency corporate card: issue physical and virtual cards to team members, set per-currency spending limits, and track expenses in the app. The Basic plan costs AUD 0/month and includes one free metal card.
The free tier limits mid-market FX to AUD 15,000/month (weekdays only — 1% surcharge on weekends). For a startup whose international spend falls under this threshold, Revolut’s cards are genuinely free. The trade-off: local receiving account details are limited compared to Airwallex and Wise, making Revolut a better spending tool than a receiving tool.
The Optimal Two-Account Setup for Australian Startups
Based on our testing and fee calculations, the cheapest business banking stack for an Australian startup looks like this:
- NAB Business Transaction Account (AUD 0/month) — Domestic operations: payroll, BPay, ATO payments, domestic supplier payments via direct debit. Unlimited free electronic transactions.
- Airwallex Core (USD 0/month) — International operations: receiving foreign currency from clients and marketplaces, paying overseas suppliers, converting currencies at mid-market.
Total recurring banking cost: AUD 0/month.
This setup handles every common startup banking need: BPay and direct debit (NAB), multi-currency receiving (Airwallex), international supplier payments at mid-market (Airwallex), and domestic payroll (NAB or Airwallex AUD account).
Sole Trader vs Pty Ltd — Banking Requirements Differ
Sole traders (ABN without a separate legal entity) can legally use a personal bank account for business transactions — though the ATO recommends separating business and personal banking. Wise Personal (free) covers international payments without the AUD 31 business setup fee. Pair it with a free personal transaction account (NAB Classic, CommBank Smart Access) for domestic banking.
Pty Ltd companies must have a business bank account in the company’s name. The two-account setup above (NAB Business + Airwallex) meets this requirement at AUD 0/month.
Frequently Asked Questions
Can I open an Airwallex account without an ABN?
Airwallex requires an ABN or equivalent business registration. Sole traders with an ABN can open an Airwallex account. Companies without an ABN (registering soon) should start with Wise, which accepts a wider range of proof-of-business documents depending on the country.
Which bank has the best startup support in Australia?
NAB runs a dedicated startup program with discounted merchant services and connection to co-working spaces. CommBank has partnership agreements with several startup hubs and accelerators. Neither offers materially better banking terms than the standard free accounts — the startup programs add value through networking and discounted EFTPOS, not through cheaper bank accounts.
Do fintech business accounts work for ATO payments?
Airwallex and Wise support AUD payments, but neither supports BPay — the primary ATO payment method. You can pay the ATO via direct credit from an Airwallex AUD account, but the process is less straightforward than BPay. Most startups keep a traditional bank account for ATO payments and use fintech for international transactions.
What about Suncorp, Bankwest, or Macquarie for business banking?
Suncorp’s Business Essentials account costs AUD 0/month with free electronic transactions, similar to NAB. Bankwest’s Business Lite costs AUD 0/month but is limited to 20 free transactions — tight for active startups. Macquarie’s Business Savings Account functions as a high-interest (1.35% as of May 2026) place to park surplus cash but does not replace a transaction account.
Can I get a business credit card with a fintech account?
Airwallex and Revolut issue debit cards — not credit cards. If your startup needs a credit card for cash flow management, you need a traditional bank or a standalone credit card product like American Express Business. Wise offers a debit card only. For startups, a debit card pulling from the cash balance is usually sufficient and avoids interest charges.
How long does it take to open a business bank account?
NAB and CommBank: same-day to 2 business days (online application with ABN/ACN lookup). Airwallex: 2–5 business days (requires director verification via passport or driver’s licence). Wise: 1–2 business days. Plan to apply for both the domestic account and the fintech account simultaneously to minimise waiting time.
Do these accounts integrate with Xero and QuickBooks?
NAB and CommBank provide automatic bank feeds to Xero and QuickBooks. Airwallex offers direct Xero integration on the Grow plan (AUD 29/month) and CSV export on Core. Wise integrates with Xero, QuickBooks, and FreeAgent on all plans. Revolut integrates with Xero on paid plans only.
Final Verdict — Free Banking Exists, You Just Have to Split It
Australian startups can access free business banking by splitting domestic and international needs across two providers. NAB’s zero-fee transaction account handles all domestic requirements — BPay, payroll, ATO — at no monthly cost. Airwallex’s free Core plan handles all international payments at mid-market rates. Combined, the two-account setup costs AUD 0/month and covers every banking need a startup faces in its first 18 months.
