Here's a practical rundown of the business credit cards Australian business owners and sole traders actually gravitate toward right now, broken down by what they're best for:

For rewards on everyday/software spend

American Express Business Explorer – Widely regarded as a top pick, this card offers free airline lounge passes, complimentary travel insurance and even using Membership Rewards Points to pay down your business credit card balance. The interest rate is currently advertised at 23.99% p.a., which comes in at around the industry average, though you get up to 55 interest-free days if you pay in full.

American Express Business (standard/lower-fee option) – If your business spends heavily on digital tools, this is worth a look. The 3x earn rate on Xero, Google Ads, Meta, and AWS is unique to this card and extremely valuable if those are significant line items for you, and the $650 annual credit with participating B2B merchants adds further value. Just be aware that Amex is not accepted everywhere — some suppliers, particularly trades and smaller businesses, do not take it, so if more than 30% of your supplier payments can't go on Amex, you'll need a Visa or Mastercard as well.

For premium travel perks (bigger spenders)

American Express Platinum Business – This is the top-tier option for businesses spending big. It's best for high-spending businesses ($150,000+ per year on card) that want premium travel benefits, and includes access to over 1,400 airport lounges worldwide, complimentary hotel loyalty status (Marriott Gold, Hilton Gold), and comprehensive travel insurance. There's currently a huge sign-up incentive too — 350,000 Bonus Membership Rewards Points when new card members apply by 14 July 2026, are approved, and spend $12,000 on eligible purchases on the new card within 3 months of approval. The catch: the $1,750 annual fee requires significant spend to justify.

For Qantas Points enthusiasts

NAB Business Signature Card – Popular with businesses wanting frequent flyer points on everyday spend. It's structured for businesses that want to earn Qantas Points on eligible everyday spending, while still getting access to travel-related perks, with a purchase interest rate of 18.50%. There's also a strong welcome offer: 150,000 Qantas Points when spending $10,000 within 3 months, plus complimentary unauthorised transaction and transit accident insurance.

ANZ Business Black – Another travel-focused favourite, particularly noted for its Qantas Points earning and built-in travel perks — a solid alternative to the NAB card if you're comparing the big four banks.

For low interest / practical business management

Westpac Altitude Business Platinum – Positioned as offering tools, features, and "meaningful rewards" for new and established business owners alike.

St.George BusinessVantage Visa – Consistently rated as the go-to for best low interest business credit card in Australia, making it a solid pick if you tend to carry a balance rather than pay in full each month.

CommBank Business cards – Good for larger teams. These cards suit businesses with high monthly spending who can pay off their balance each month to take full advantage of the interest-free period, and for businesses focused on keeping interest charges low and managing a large team of cardholders, CommBank's option offers practical features and scalable access.

Bottom line for choosing:

• Heavy digital/software spend? → Amex Business (Xero/Google Ads/Meta/AW

For Australian businesses, American Express leads in rewards and frequent flyer benefits, NAB, Westpac, and ANZ offer strong Visa/Mastercard options, while fintech cards like Airwallex and Wise are ideal for international transactions.
