Your Credit Score in Australia: What It Means, What's Good, and How to Improve It

🏦 What is a credit score in Australia?🔗

🎯 The essential: A credit score is a number calculated from your credit report. Higher is better, and it directly affects whether you're approved and what rate you're offered.

Lenders use it, alongside your income and expenses, to decide whether to approve your application and what interest rate to offer. A high score can mean faster approvals and better rates. A low score can mean rejection, or being pushed toward specialist lenders charging significantly more.

Your credit report is the underlying document, containing your credit history: loan applications, missed payments, defaults, and accounts opened or closed. Your score is a number derived from that report at a point in time, and it changes as new data comes in from lenders, often monthly.

📊 Why you have two different credit scores🔗

Australia used to have three consumer credit bureaus: Equifax, Experian, and illion. In October 2024, Experian completed an acquisition of illion's Australian and New Zealand business. illion no longer operates as an independent consumer credit bureau, its site now redirects to Experian, so in practice you'll deal with two bureaus going forward: Equifax and Experian.

Each bureau still operates its own scoring model, built from data that different lenders choose to report to it. Not every lender reports to both bureaus, your home loan might only appear on one file, a BNPL default might only show on the other. So the two bureaus can genuinely disagree on the same person on the same day, and both scores are correct.

The practical implication: check both before a major finance application. The lender will pull whichever bureau it uses, CommBank, NAB, Westpac and ANZ lean heavily on Equifax, while many fintechs, non-bank lenders and BNPL providers use Experian.

✅ What is a good credit score?🔗

Both bureaus now use a broadly similar 0 to 1,200 scale. Equifax publishes its bands clearly:

Equifax describes each band in terms of risk: a "Good" score means an adverse event, like a default, is less likely than average to appear on your report in the next 12 months.

Experian moved to the same 0 to 1,200 range following the illion acquisition. Its exact band cut-offs may not line up precisely with Equifax's, check experian.com.au for its current published bands before treating any single number as gospel.

What we can say clearly: a score in the bottom band on either bureau will limit your options to specialist lenders, typically at meaningfully higher rates, and can affect whether Lenders Mortgage Insurance is even offered on a home loan application.

🔢 How your credit score is calculated🔗

Each bureau uses its own proprietary formula, but the factors that matter are broadly consistent across both:

• Repayment history. Under Comprehensive Credit Reporting, the last 24 months of your payment behaviour is visible: on time, 14 days late, 30 days late, 60 days late, 90+ days late. A clean 24-month record is worth more than anything else you can do.
• Credit enquiries. Every application creates a hard enquiry, recorded on your file for five years. One enquiry is a minor impact, four or more in 12 months is a red flag, bureaus read clusters as a sign of financial stress.
• Defaults and negative listings. A single default can drop your score sharply. Defaults are recorded when a debt of $150 or more is at least 60 days overdue and the lender has demanded payment. They stay on file for five years, court judgements for five years, serious credit infringements for seven years.
• Credit history length and mix. Older accounts help. A mix of credit types, home loan, credit card, car loan, scores better than a single product. Don't close your oldest credit card if you can avoid it.
• Personal information stability. Address stability and employment tenure factor in at lower weights.

What doesn't affect your score: your income, your savings balance, your rent payments (unless routed through a reporting lender), and checking your own score, which is a soft enquiry with zero impact.

📋 Comprehensive Credit Reporting: the rule change that helped millions🔗

Before 2018, Australian credit reports were almost entirely negative. Lenders could see your defaults and enquiries, but not your on-time payments. You could pay every bill perfectly for a decade and it wouldn't show up.

Comprehensive Credit Reporting (CCR) changed that. It was introduced via an amendment to the Privacy Act 1988, with mandatory participation for the big four banks rolled out from 1 July 2018, phased to 50% of consumer credit accounts by September 2018 and the remainder by September 2019.

What CCR added to your credit report: account open and close dates, credit limits on each account, repayment history for the past 24 months showing whether each monthly payment was on time, and financial hardship arrangements.

The practical result: if you've been making every repayment on time, that positive history now actively lifts your score. Note that telcos and utilities aren't required to report positive repayment history, only licensed credit providers are, so paying your phone bill on time won't boost your score, but letting it escalate to a default can still hurt you.

🆓 How to get your free credit report🔗

You have a legal right to a free credit report every three months from each bureau, guaranteed under the Privacy Act 1988 and confirmed by the OAIC. You're also entitled to an extra free report within 90 days of being declined for credit, or if your credit information has been corrected.

• Equifax: equifax.com.au
• Experian: experian.com.au

Checking your own report is a soft enquiry. It does not affect your score, there's no reason not to check both.

🛠️ How to improve your credit score🔗

Generic advice like "pay your bills on time" is correct but not very actionable. Here's what actually moves the needle:

1. Pull both reports before you do anything else. Check Equifax and Experian for errors: incorrect defaults, duplicate enquiries, accounts you don't recognise. Disputes go to the credit provider first, then the OAIC if unresolved.
2. Stop applying for credit. If a major application, home loan, car loan, is on the horizon in the next 6-12 months, pause everything else, even a new card "for the points."
3. Reduce credit card utilisation below 30%. A $10,000 limit carrying $8,000 is 80% utilisation. Scoring models read high utilisation as financial stress, regardless of whether you pay in full each month. If multiple cards are the issue, consolidating them into one lower-utilisation loan is worth weighing up.
4. Set up direct debits for every credit account. Under CCR, every monthly payment status is now recorded. One 30-day late marker can suppress your score for two years.
5. Don't close old accounts. Your oldest card contributes positively to credit history length. Keep it open with a small recurring charge and pay it off automatically.
6. Be patient with existing defaults. A default stays five years regardless of whether you pay it off, paying it won't remove it, but it stops it getting worse, and the impact fades as the listing ages.
