Most Perth builders, tradies and property investors are running serious money through their business every month — materials at Bunnings and Tradelink, fuel for the ute fleet, subcontractor invoices, accounting software, equipment hire, site insurances. The spend is already happening. The question is whether it's earning anything back.
Used carefully, a business credit card turns that everyday outflow into Qantas Points, Velocity Points, Membership Rewards or straight cashback — without changing what you buy or who you buy it from. Used carelessly, it becomes an expensive line of revolving credit. This is a short, practical read on how to make the first thing happen instead of the second.
Why This Matters More for Trades and Property Than Most Industries
A few structural realities make construction, trades and property investment particularly well-suited to a rewards strategy:
- High and predictable spend. Even a small building business often clears $30,000–$80,000 a month on materials and subbies. A property developer running a single project can easily push seven figures through suppliers in a year.
- Long supplier payment terms work in your favour. Most trade accounts run on 30-day terms anyway. Pairing those with a card that offers up to 55 interest-free days can extend your working capital window without touching an overdraft.
- Multiple cardholders, one points pool. Issue cards to your site supervisor, project manager and office admin. All spend funnels into one rewards account, accelerating earn rates without losing control of approvals.
- Cleaner bookkeeping. A dedicated business card creates a clean transaction feed straight into Xero or MYOB — fewer reimbursements, fewer "where did this $480 at Reece come from?" conversations at month-end.
- Travel perks that suit the work. Lounge access, complimentary travel insurance and fee-free international transactions matter when you're flying to suppliers in Melbourne, inspecting projects interstate, or sourcing fixtures from overseas.
A Quick Reality Check on the Maths
Rewards cards only work in your favour if two things are true:
- You pay the balance in full every month. Interest rates on rewards cards sit between 18% and 23% p.a. — that wipes out any points you've earned several times over.
- Your annual rewards value comfortably exceeds the annual fee. As a rough benchmark, a Qantas Point is worth around 1.5 to 2 cents when redeemed for flights or upgrades. On a card earning 1 point per dollar with a $450 annual fee, you'd want to be putting at least $30,000–$45,000 a year through it to break even — and most trade businesses easily clear that.
There's also the question of surcharges. Some suppliers and the ATO pass on card fees that can quietly eat your rewards margin. The trick is to be deliberate: card-friendly suppliers earn the points; surcharged transactions get paid by EFT.
Three Business Cards Worth a Closer Look in 2026
The Australian business card market shifts constantly — bonus offers, earn rates and partner programs change every few months. The three cards below have held a strong position into 2026 and cover three different use cases: maximum points, bank-issued flexibility, and a genuinely low annual fee.
1. American Express Qantas Business Rewards Card — the high-earner
Annual fee: $450 · Earn rate: 2 Qantas Points / $1 on Qantas spend, 1.25 / $1 on most other business spend, 0.5 / $1 at government bodies including the ATO · Headline draw: uncapped points and a recurring 150,000–170,000 bonus point sign-up offer
This is the card most accountants quietly run themselves. Uncapped earning is the real selling point — there's no monthly or annual cap that throttles you once your spend grows. The ATO earn rate is the second quietly powerful feature: most cards earn nothing on tax payments, and BAS, PAYG and income tax instalments add up fast for a profitable building business. Acceptance has improved markedly in recent years, but you'll still find the occasional supplier or subcontractor who only takes Visa or Mastercard — which is why most operators run an Amex alongside a Visa or Mastercard, not instead of one.
2. NAB Qantas Business Signature Card — the bank-issued workhorse
Annual fee: $295 · Earn rate: 1 Qantas Point / $1 (capped at $10,000 per statement) then 0.5 / $1 thereafter · Headline draws: Visa acceptance everywhere, complimentary domestic and international travel insurance, up to 55 interest-free days
For businesses that want broader acceptance than Amex offers and a relationship with one of the major banks, the NAB Qantas Business Signature is the standard answer. The earn rate is lower than Amex on paper, but the cap structure suits the kind of business that runs steady five-figure monthly spend rather than lumpy six-figure months. Pair it with an integrated NAB business transaction account and the bookkeeping reconciliation through Xero or MYOB is essentially automatic.
3. American Express Qantas Business Card — the low-fee entry point
Annual fee: $109 · Earn rate: 1 Qantas Point / $1 on most business spend, with bonus points on eligible Qantas purchases · Headline draws: free additional employee cards, no points cap, straightforward break-even on modest spend
For sole traders, sub-contractors and smaller trade businesses where a $295 or $450 annual fee feels like overkill, this is the sensible starter. At $109 a year with no points cap and free supplementary cards, the break-even threshold is low — even $10,000–$15,000 of annual spend can justify it once the points are redeemed against Qantas flights or upgrades. It's also a useful "second card" in larger setups: a low-fee Amex for personal expenses and one or two staff, with a higher-tier card handling the bulk of the trade spend.
Worth knowing: Annual fees, earn rates, bonus offers and surcharge rules change frequently. Always confirm the current product disclosure statement before applying — and check whether the bonus point offer requires a minimum spend in the first three months that you'd hit naturally.
Getting the Most Out of Whichever Card You Choose
- Move recurring spend onto the card deliberately. Software subscriptions, insurance premiums, fuel cards, mobile plans, supplier accounts that accept card without surcharge — set them up once and forget them.
- Pay BAS and PAYG via card only when the maths works. The ATO surcharge typically sits between 1.0% and 1.4% depending on card type. If your effective points value exceeds the surcharge, it's a net win. If not, pay by BPAY.
- Use Qantas Business Rewards as well as the card program. It's free to join, layers on top of card earn rates, and lets the business earn points on flights, fuel at BP, and select suppliers — separately from anything the card delivers.
- Direct debit the full balance every month. Set and forget. This is the single discipline that separates a profitable rewards strategy from an expensive habit.
- Review annually. Bonus offers, partner rates and your own spend pattern all shift. The card that suited a one-ute operation doesn't necessarily suit the same business three years later with four staff and a leased yard.
A Quiet Word on Structure
If your business runs through a company or trust, make sure the card is issued in the business entity's name where possible, the rewards account is linked to the business, and personal spend stays off the card entirely. Mixed-use cards create unnecessary headaches at tax time, complicate FBT and private-use apportionment, and quietly erode the audit trail your bookkeeper relies on.
None of this is exotic. It's just being deliberate about money that's already moving — turning routine outflow into something with a tail. For a business running $500,000–$2,000,000 of card-friendly spend through the year, the difference between "no card" and "the right card, used properly" can be a family holiday, a fully paid set of business-class flights, or several thousand dollars of cashback — every single year.
