If you are trying to build or protect your credit score, you may have wondered whether it is better to hold a few large credit products (e.g. a single high-limit credit card and a home loan) or to spread your borrowing across several smaller cards and loans. In Australia, the answer is not really about size or count at all.
Under the comprehensive credit reporting (CCR) regime that has applied since 2018, credit reporting bodies record far more detail about how you manage credit than they once did, including your monthly repayment behaviour. The way you handle your accounts now matters far more than how many you hold.
How Credit Scores Work
Australia has two main credit reporting bodies: Equifax and Experian, and each calculates its own score using the information held on your credit file. An Equifax credit score sits between 0 and 1,200, with a higher score signalling lower risk to lenders.
Equifax publishes the broad weightings behind its score: credit enquiries and applications account for around 40%, repayment history around 38%, adverse events 7%, personal information 6%, and information on credit accounts 4%, with the remainder split across commercial credit, address and length of credit history. These figures are Equifax-specific, but they point to what matters most: applications and repayment behaviour together dominate the calculation, and neither is directly about how many products you hold.
What Appears on Your Credit File
For every credit product you have held in the last 2 years, your credit report can list the type of product (such as credit card, store card, home loan or personal loan), the credit provider, your credit limit, and the opening and closing dates of the account. Under the CCR, your report also includes monthly repayment history information, typically covering the past 24 months.
This matters because lenders look at the total amount of credit accessible to you across all accounts and loans, not simply the number of credit products. A single card with a $15,000 limit and three cards with $5,000 limits each represent the same total accessible credit to a lender, even though one is “few large” and the other is “several smaller.”
Does the Number of Products Matter?
Not in isolation. CreditSmart is explicit that “the more credit you have, the more it will affect, and probably reduce, your credit score,” but adds that this can be offset by good repayment behaviour. The issue is not having several products per se; it is having more total credit than you can comfortably manage.
Each additional card or loan brings another repayment, another due date, and another opportunity to miss a payment. CreditSmart notes that taking on too many accounts may make it difficult ot afford all your monthly repayments, which is why lenders may view a cluster of new accounts as a warning sign. A small number of well-managed products is generally easier to keep on top of, with fewer due dates and a simpler financial picture to monitor.
The Credit Utilisation Factor
Credit utilisation: the share of your available credit limit that you are actually using, is one of the key factors influencing your score, particularly on revolving accounts such as credit cards. Many lenders and credit-score providers prefer to see utilisation kept low, often below about 30%, and using more than around 70% of your limit can be treated as a sign that your borrowing is not under control.
This is where the “several smaller” approach can cut both ways. Several cards can give you a larger combined credit limit, which can lower your utilisation if your balances are low, but the same structure becomes a liability if you carry a balance close to the limit on more than one card. With a few larger products, the maths is simpler: keep the balance well below the limit and utilisation stays healthy.
The Borrowing Capacity Trap
There is a separate consideration that sits outside your credit score but directly affects your ability to borrow. When assessing a home loan or other credit application, lenders typically consider the full approved credit limit on your cards as potential debt, even if you rarely use them. A single large-limit card and several smaller-limit cards can therefore reduce your borrowing capacity by a similar amount, because what matters to the lender is the total limit, not the balance or the number of cards. Unused cards are not “free”, they still sit on your file as accessible credit.
Applications and Enquiries
Every time you apply for credit, a hard enquiry is recorded on your file, and these remain visible for 5 years. Since enquiries and applications make up the largest single component of an Equifax score, your application pattern matters a great deal.
One application is unlikely to hurt your score on its own, but several within a short period can, because they may suggest you are taking on too much credit too quickly or are under financial stress. Opening several smaller products usually means several separate applications and several enquiries in a short window.
Repayment Behaviour Is the Deciding Factor
Under CCR, your repayment history across all open credit accounts is recorded and feeds directly into your score, with a payment generally only flagged as missed if it is at least 14 days late. Because repayment history carries the second-largest weighting in the Equifax model, consistent on-time payments are one of the most powerful things you can do for your score.
This is why, for most Australians, the structure that wins is the one you can manage without missed payments: a small number of products with sensible limits, low balances, and a clean repayment record.
So, Which Is Better?
Neither approach is inherently better. What affects your score is not the number of products or their individual size, but the combination of total credit exposure, your utilisation, your application pattern, and above all, your repayment behaviour.
| Approach | Potential advantages | Potential drawbacks |
| Few large products | Fewer due dates and applications to manage; simpler to monitor | Large limits can reduce borrowing capacity; a single high balance can push up utilisation |
| Several smaller products | May spread balances and keep per-card utilisation lower | More due dates and enquiries; higher total accessible credit; greater chance of a missed payment |
As a rule of thumb, a small number of well-managed products with sensible limits is usually better than several unnecessary ones, but the right number is simply the number you can manage without missed payments, high utilisation, or repeated applications.
Practical Steps for Consumers
- Keep total limits modest. Lenders look at the total credit accessible to you, so reduce limits you no longer need.
- Keep utilisation low. Aim to use well below about 30% of your available limit on cards, and avoid sitting near the limit.
- Space out applications. Each application creates a hard enquiry that stays on your file for 5 years, so avoid several in a short period.
- Pay on time, EVERY time. Repayment history is a top factor; a payment is only flagged as missed if it is 14 or more days late.
- Check your report. You are entitled to a free copy of your credit file every 3 months from each reporting body.
How Clear Credit Solutions Can Help
If your credit report contains listings you believe are inaccurate, such as a default you do not recognise, a duplicated enquiry, or an account that should have been removed, you have the right to request a correction with the credit reporting bodies.
