How Many Credit Cards Can You Have in Australia?
By Craig McNamara · Published on 26 July 2026
People ask me this a lot, usually after they find out I churn credit cards: "wait, how many cards are you even allowed to have?"
Short answer: there is no legal limit on how many credit cards you can hold in Australia. No law, no regulator cap, no magic number.
But in practice you'll hit a ceiling well before you'd expect — and it's not "banks get suspicious after 5 cards." It's three specific mechanisms.
The real cap: the 3-year serviceability assessment
Since 1 January 2019, every credit card application in Australia is assessed under a rule ASIC prescribed in the ASIC Credit (Unsuitability — Credit Cards) Instrument 2018/753: the lender must assess whether you could repay the full credit limit within three years.
Not your typical balance. Not your actual spending. The full limit, as if you'd maxed the card out.
And it compounds: lenders have to weigh your existing cards in the same assessment — and because your credit file shows each card's limit rather than its balance (more on that below), every card you already hold gets counted at its full limit. Moneysmart puts it plainly: your credit limit "is based on your ability to pay it back within three years."
So each card you hold eats a chunk of your assessed capacity, whether or not you ever carry a balance. Three cards with $15,000 limits each means the next lender assesses you as if you might owe $45,000 tomorrow and need to clear it within three years — on top of the new card's limit.
This is the actual answer to "how many cards can I have": as many as your income can service under the 3-year test. Higher income, more headroom. Lots of open cards with fat limits, less headroom — until eventually a lender runs the numbers and says no. It's also why churners take the minimum limit that qualifies for a card, and close cards once the bonus lands: a closed card's limit stops counting against the next application.
Your credit file shows limits, not balances
The second mechanism is what lenders can see. Under comprehensive credit reporting, your credit report includes the credit limit of every account — but not the balance you actually owe. It also shows:
- Every application you've made, for 5 years — approved or declined
- 24 months of repayment history on each account
- Account details (type of debt, credit limit) for every account — staying visible for 2 years after the account is closed
Two consequences for anyone holding multiple cards:
- An unused card still counts against you. A $20,000-limit card sitting in a drawer with a $0 balance looks identical, on your file, to one that's maxed out. The lender assumes the worst.
- Application velocity is visible. Every application leaves an enquiry for 5 years, and Moneysmart lists the number of applications you've made as one of the inputs to your credit score. Moneysmart's credit card guidance is blunter still: "If you apply several times in a short period of time, it can harm your credit score."
So the file doesn't limit how many cards you can hold — it punishes how fast you apply. That's why I space applications out to roughly one every 3–4 months. I dig into the score mechanics in do credit card applications hurt your credit score? — and you can pull your own report for free every 3 months from each bureau to see exactly what lenders see.
The third cap: more cards doesn't mean more bonuses
Even if you could get approved for ten cards, there's a reason nobody serious about points holds ten cards at once: issuer waiting periods make most of them worthless for bonuses.
Almost every major issuer excludes you from the signup bonus if you've recently held one of their cards — and the exclusion usually covers the whole card family, not just the exact card. Straight from ANZ's current offer terms:
"You are not eligible for the initial bonus Qantas Points if you currently hold or have held an ANZ Rewards or ANZ Frequent Flyer credit card in the last 24 months."
Hold one ANZ rewards card and every other ANZ rewards card is bonus-dead to you for two years. American Express is broader again — its current offers are for "New Amex Card Members only," which is one clock across the entire Amex stable, not per card.
Notice the wording: "currently hold or have held." Holding a card doesn't just fail to help — it actively blocks that issuer's next bonus, and for exclusions counted from when you stop holding the card, the clock can't even start until you close it. A big standing card collection is a machine for disqualifying yourself.
The signup bonus is where nearly all the value is — it usually dwarfs years of everyday earn, which is the whole premise of churning. So the useful question was never "how many cards can I hold?" It's "how many issuers have an open bonus clock for me right now?" I keep every issuer's current waiting period on the credit card eligibility rules page, and the strategy of ordering applications around those clocks gets its own post: sequencing credit card applications.
What actually caps you, summarised
| Constraint | Imposed by | What it means in practice |
|---|---|---|
| Legal limit on card count | Nobody | Doesn't exist |
| 3-year serviceability test | ASIC rule, applied by every lender | Total limits across all your cards must be repayable within 3 years on your income |
| Credit file visibility | Comprehensive credit reporting | Lenders see every limit (not balances) and every application for 5 years |
| Issuer waiting periods | Each bank's bonus terms | Holding a card blocks that issuer's bonuses; most clocks are 12–24 months |
How many do I actually hold at once?
Usually one or two. Not because I couldn't get approved for more — because there's no reason to.
My cycle, covered in full in the churning guide, is: apply, hit the minimum spend, collect the bonus, cancel before the second-year fee, wait out the exclusion period, repeat. Cancelling does two jobs at once: it frees serviceability for the next application, and it starts (or keeps clean) the issuer's exclusion clock. The cards flow through my wallet rather than piling up in it.
The exception is a card that earns its keep on ongoing benefits — lounge access, insurance, perks that cover the fee. That's a different calculation, and sometimes a retention offer changes the maths on keeping one. And if your household has two adults, there's a clean way to double bonus throughput without doubling anyone's card count — two-player churning.
The home loan asterisk
Home loan lenders apply the same limit-based logic — your card limits reduce how much they'll lend you, regardless of balances. If a property purchase is anywhere on the horizon, the calculus around open cards changes completely: churning credit cards around a home loan.
The short version
- No legal limit exists on the number of credit cards in Australia.
- Approvals are capped by the 3-year serviceability test: since 1 January 2019, lenders must assess whether you could repay the full credit limit within three years (ASIC) — and your existing card limits weigh into the same assessment.
- Your credit file shows limits, not balances, plus every application for 5 years (CreditSmart) — unused cards still shrink your capacity, and rapid-fire applications hurt your score.
- Holding cards blocks bonuses: issuer exclusion windows of 12–24 months are the real ceiling for points collectors — tracked on the eligibility rules page.
- The question worth asking isn't "how many can I have" but "which bonuses am I eligible for right now" — logging your card history on the site answers that automatically.
