How credit cards affect your credit report in Australia: limits, enquiries and repayments

Each credit card you apply for and hold leaves several traces on your Australian credit report: an enquiry for the application, an account showing the issuer, the type of credit and the credit limit, and up to two years of monthly repayment history showing whether you paid at least the minimum on time. Your balance and how much you spend are not reported to credit reporting bodies under the current rules, but your limit is, and lenders will usually ask about balances and see them in your bank statements. For rewards card holders, the practical points are: apply for one card at a time, pay on time every month, keep total limits modest, and close cards you no longer use before a major loan application.

This guide belongs to the pitfalls, protections and official sources section. The rules are in Part IIIA of the Privacy Act 1988 and the Privacy (Credit Reporting) Code. General information only.

What a credit card adds to your report

A repayment is generally recorded as late once it is more than 14 days past the due date. For a card, the relevant payment is the minimum repayment: paying the minimum on time keeps your repayment history clean, even though it costs interest. Paying the full balance is about cost, not credit reporting.

Why the limit matters more than the balance

When you apply for a home loan, car loan or another card, the new lender assesses your existing credit cards by their limit, typically as a monthly commitment based on a percentage of the limit or on repaying it over a period. A $20,000 limit you never use can therefore reduce what you can borrow as much as if it were fully drawn.

Illustrative example: a home lender that assesses card limits at about 3.8% a month treats a $20,000 limit as a commitment of about $760 a month. Over a 30-year home loan at an assessment rate of 8.5%, $760 a month of servicing capacity corresponds to roughly $99,000 of borrowing. Lenders use their own formulas, but the direction is the same.

Before a big application:

• Close cards you do not need, and reduce limits on the ones you keep. See reducing your limit and cancelling online.
• Allow time for the change to show on your report and in the lender's checks.
• Avoid new card applications in the months beforehand.

Enquiries from applying for rewards cards

Applying for several cards to collect sign-up bonuses adds several enquiries. Lenders and scoring models can read many enquiries in a short period as a sign of financial pressure. See sign-up bonus points maths.

Ways to limit enquiries:

• Check eligibility criteria and any income minimums before applying.
• Use eligibility or pre-assessment tools that state they do not record an enquiry, if offered.
• Space applications out.

Credit scores and card behaviour

Equifax and Experian each calculate their own credit score from your report; Experian acquired illion's consumer bureau in 2024. Behaviours that generally support a good score include paying at least the minimum on time every month, few recent enquiries, no defaults and a steady credit history. Lenders also apply their own credit policies, so a score is only part of an application.

You can get your credit report free every three months from each credit reporting body, and again if you have been refused credit in the last 90 days.

Worked example: preparing for a home loan (illustrative)

Lee and Jo hold four cards: two rewards cards with $15,000 limits each, a $6,000 no-fee card and a $4,000 store card. They pay everything in full monthly and want to apply for a home loan in six months.

1. They get free reports from Equifax and Experian and check every account is correct.
2. They keep one rewards card, reduce its limit to $8,000, and close the others after redeeming points.
3. Total limits fall from $40,000 to $8,000.
4. At an illustrative 3.8% a month, assessed commitments fall from about $1,520 to about $304 a month.
5. They make no new applications before the home loan.

The closed accounts will stay on their reports, marked closed, for two years, which is normal.

Fixing card-related errors

If your report shows a card you never opened, a wrong limit, a late payment you made on time, or a default that should not be there:

1. Ask the credit reporting body or the card issuer to correct it. Corrections should generally be dealt with within 30 days unless you agree to more time.
2. Provide statements or payment receipts.
3. If not resolved, complain to AFCA (for issuers) or the Office of the Australian Information Commissioner (OAIC).

An unknown card may mean identity theft; see fraud, chargebacks and the ePayments Code.

Frequently asked questions

Does carrying a balance hurt my score if I pay the minimum on time?

Your repayment history shows on-time payments. The balance itself is not reported to credit bureaus, but lenders see it in statements and it costs you interest.

Does a hardship arrangement on my card show as a missed payment?

Months under a hardship arrangement are reported as financial hardship information rather than as missed payments, and are kept for one year.

Do BNPL accounts appear too?

Since BNPL became regulated credit on 10 June 2025, providers can report accounts and repayments like other consumer credit. See BNPL compared with credit cards.

Should I keep an old card open to build history?

Your history includes closed accounts for two years after closing. Keeping a card only for history usually matters less than keeping total limits low.
