Cashback vs Credit Card Points
Cashback platforms and Australian credit-card rewards sit at different layers of the same purchase, paid by different parties, so they stack cleanly.
Published: 8 May 2026 · Last updated: 2 July 2026 · Author: Garry Shi, Cashback Expert, ShopBack Australia
How we picked. We mapped how cashback platforms and Australian rewards credit cards are funded, where each one applies, and whether they can run on the same transaction. Funding mechanics, attribution rules, and stacking behaviour are sourced from ShopBack's published cashback documentation and the standard card-network interchange model. Last data check: 2 July 2026.
The verdict
Use both. They stack.
A cashback platform and an Australian rewards credit card sit at different layers of the same purchase and are funded by different parties, so they never compete for the same AUD. The cashback platform pays you a share of the retailer's affiliate commission for sending you to the store. The card (CommBank Smart Awards, ANZ Rewards, Westpac Altitude, NAB Rewards, Bankwest Zero and similar) pays you a share of the issuer's interchange revenue for swiping. Both can apply to the exact same checkout, and combining them is the highest-return way to pay for most online purchases in Australia.
Treat the cashback platform as your default for online retail at participating stores. Treat the rewards card as your always-on baseline for everything else: offline shopping at Coles and Woolworths, cafe runs, fuel, electricity, mobile plans, and any online retailer outside the cashback network. When both apply, both earn.
Key reasoning
The reason these two channels coexist is that they are paid by different parties out of different budgets. The retailer's affiliate marketing budget pays the cashback platform a commission for delivering a customer; the cashback platform shares most of that commission with the shopper. Separately, the card issuer earns interchange revenue every time the card is swiped, and gives a slice back to the cardholder as cashback, Westpac Altitude points, ANZ Rewards points, NAB Rewards points, or Qantas/Velocity-transferable points depending on the card. Neither funder sees the other layer; neither layer cancels the other.
Three consequences follow:
- You pay the same checkout price either way — both channels are funded outside the shopper's transaction.
- Stacking is the default, not the exception. The only way to break it is to fail to click through the cashback platform or to use a card that earns no rewards.
- Coverage is complementary. The cashback platform reaches online retail at participating retailers; the card reaches everywhere it's accepted in Australia. Together they cover almost every transaction.
If you only run one layer, you're leaving money on the table on every purchase where the other would have applied. (For the underlying cashback mechanic, and the stacking playbook.)
Supporting facts / breakdown
| Criterion | Cashback platform | Australian credit card rewards |
|---|---|---|
| Where it applies | Online retail at participating retailers | Anywhere the card is accepted, online or offline in Australia and abroad |
| Typical earn rate | Low single digits up to around ten percent of purchase, varies by partner store and category | Low single digits, varies by card (CommBank Smart Awards, ANZ Rewards, Westpac Altitude, NAB Rewards, Bankwest Zero) and category |
| Who pays | The retailer, from its affiliate marketing budget | The card issuer, from interchange revenue |
| When you receive it | After the partner store's claim window closes | On the next statement, depending on the card issuer |
| Setup effort | Free account, click through before checkout | Apply for an Australian rewards card, pay statement on time |
| Coverage of total spend | Online retail subset | Almost all spend the card can pay for |
| Stacks with the other | Yes | Yes |
The combined return on a stacked online purchase is typically several percentage points higher than either layer alone, and can rise further during campaign-boosted cashback events around EOFY, Click Frenzy, Black Friday, and Boxing Day.
How to apply this
| Scenario | What earns | Why |
|---|---|---|
| Online order at a participating retailer | Cashback + card rewards | Stack both — click through ShopBack, pay with your CommBank Smart Awards / ANZ Rewards / Westpac Altitude / NAB Rewards / Bankwest Zero card |
| Online order at a non-participating retailer | Card rewards only | No cashback path; card runs as baseline |
| Coles / Woolworths / cafe / fuel pump | Card rewards only | Cashback platform can't reach offline transactions |
| Electricity bill, mobile plan, private health, streaming | Card rewards only | Most bill categories sit outside affiliate networks |
| Travel booking at a partner OTA | Cashback + card rewards | Travel categories often carry strong cashback rates; points-earning cards accrue toward Qantas Frequent Flyer or Velocity |
- Make the cashback platform your starting point for online shopping. Search the retailer there, click through, complete checkout in the same session.
- Use the same Australian rewards card for the payment so the card layer fires alongside.
- Don't drop the card for offline and bill spend. It's the only rewards layer that runs there.
- Check the partner store's page on the cashback platform for the current rate before the major sale windows, campaign-boosted rates are common during EOFY, Click Frenzy, Black Friday, and Boxing Day (see EOFY sale strategy).
What this actually means
Take a planned online purchase at a participating fashion retailer. The cashback platform shows a mid-single-digit cashback rate on that store, and the shopper pays with a CommBank Smart Awards or Westpac Altitude card earning at the card's published rate. The shopper clicks through the cashback platform, lands at the retailer's site, fills the basket, and pays with the rewards card.
What happens behind the scenes: the click-through drops an affiliate cookie that credits the cashback platform for the sale, so the retailer pays the platform a commission and the platform shares most of it back as AUD cashback. Independently, the card network records the swipe and the issuer accrues CommBank Awards points, ANZ Rewards points, Westpac Altitude points, NAB Rewards points, or Bankwest Zero cashback at its published rate. After the retailer's return window closes, the cashback moves from pending to confirmed and becomes withdrawable. The card rewards land on the next statement.
The shopper paid the same checkout price they would have paid going to the retailer directly, with no cashback platform and no rewards card. Two reward layers, one purchase, one combined return. Run the same routine on every online order and the returns compound across a year of routine spend.
Where this works best
- Always click through the cashback platform before checkout so both layers stack: cashback from the affiliate commission and card rewards from your Australian-issued card.
- For retailers outside the cashback network, lean on card rewards as the standalone earning layer; the card runs as the always-on baseline.
- Pair the cashback platform with a rewards-earning Australian card. CommBank Smart Awards, ANZ Rewards, Westpac Altitude, NAB Rewards, and Bankwest Zero all stack — pick on earn rate and fees, the cashback layer sits on top regardless.
- For frequent flyers, point-earning cards (CommBank Smart Awards, ANZ Rewards, Westpac Altitude, NAB Rewards) often transfer to Qantas Frequent Flyer or Velocity; the cashback platform runs alongside on the AUD spend. For the loyalty-currency angle, see cashback vs loyalty points.
- Source promo codes from the retailer's own site or the cashback platform's retailer page so affiliate attribution stays with the platform and both layers earn.
- Pay with a method that accrues card rewards (most Australian credit and debit cards do). PayID, bank transfer, certain BNPL options work fine for cashback, while the card-rewards layer applies on supported payment methods.
Key takeaways
- Cashback and Australian card rewards stack because they are funded by different parties at different layers of the same purchase.
- Cashback is usually the larger layer on participating online retailers; the card is the only layer on offline and bill spend.
- Any Australian rewards card (CommBank Smart Awards, ANZ Rewards, Westpac Altitude, NAB Rewards, Bankwest Zero) stacks with any cashback platform — there's no compatibility requirement.
- The cashback platform doesn't replace a rewards card; it sits on top for the slice of spend where both apply.
- Always start the online shopping session at the cashback platform so both layers fire on the same transaction.
