With Australian household debt levels among the highest globally and property prices continuing to surge, understanding how credit scores work has never been more critical for everyday Australians.
About 15 million Australians have active credit files, yet research shows 69 per cent don't know their credit score. This knowledge gap is costly – poor credit scores can mean loan rejections or having to pay higher interest rates on the credit you do get approved for.
The Australian credit scoring system operates differently from other countries, particularly the United States, with unique features that can catch consumers off guard if they're following international advice found online.
Australia's credit landscape is dominated by three major credit reporting agencies: Equifax, Experian, and illion (formerly Dun & Bradstreet). Each uses different scoring ranges and methodologies, which means your score can vary significantly between agencies.
Equifax, Australia's largest credit bureau, uses a 0-1,200 scale where 661 and above is considered "good" and 853 and above is "excellent". They weight credit enquiries heavily at 40 per cent of your score calculation, with repayment history making up 38 per cent.
Experian operates on a 0-1,000 scale with payment history accounting for 35 per cent of your score, credit utilisation 30 per cent, and length of credit history 15 per cent.
Meanwhile, illion also uses a 0-1,000 scale but focuses heavily on bill payment consistency and was the first agency to implement Comprehensive Credit Reporting back in 2014.
The practical impact of these differences is significant. A borrower might have a "good" score with one agency but only "average" with another, affecting their loan approval chances depending on which bureau their preferred lender checks.
A major shift occurred in July 2021 when Comprehensive Credit Reporting (CCR) became mandatory for Australia's major banks. This fundamentally changed how credit scores are calculated.
Previously, credit reports only showed negative information like defaults, missed payments, bankruptcies. Under CCR, lenders now report up to 24 months of repayment history, including on-time payments.
This means Australians who consistently pay their bills on time can now see their credit scores improve, rather than just avoiding damage. As of 2025, over 80 per cent of credit providers participate in CCR.
The Australian Banking Association says the new system helps consumers with limited credit history, particularly young Australians and recent migrants, build positive credit records more quickly.
Your payment history is the single most important factor affecting your credit score. Late payments start impacting your score once they're 14 days overdue, with the severity increasing the longer you're behind.
Under CCR, this information stays on your credit report for two years, meaning consistent on-time payments can boost your score relatively quickly compared to the old system.
This measures how much of your available credit you're using. Best practice is keeping utilisation below 30 per cent of your total credit limits, though single digits optimise scores.
Unlike some overseas markets, Australian credit reports only show your credit limits, not your actual balances, which is why this calculation differs from international advice.
This includes your oldest account age, average account age, and time since your newest account opened. Many Australians inadvertently hurt their scores by closing old credit cards, not realising this shortens their credit history.
Having a mix of credit types such as credit cards, personal loans and mortgages, demonstrates your ability to manage different financial products responsibly.
Hard enquiries from credit applications remain on Australian credit reports for five years, compared to just two years in the US. Each enquiry can drop your score by 2-10 points.
However, multiple enquiries for the same type of loan within 45 days typically count as a single enquiry, allowing rate shopping without excessive score damage.
Defaults, even as small as $150, can devastate credit scores for five years regardless of whether they're eventually paid. Bankruptcies impact scores for five years from filing or two years from discharge, whichever is longer.
Start by obtaining free credit reports from Equifax, Experian, and illion. Common errors include incorrect personal details, duplicate listings, or debts that aren't yours.
Credit bureaus have 45 days to investigate disputes, with score improvements appearing shortly after corrections are approved.
If you're using a high percentage of your available credit, paying down balances or requesting limit increases can improve scores within 1-2 billing cycles.
Preventing future late payments is crucial since payment history dominates score calculations. Even being a few days late can impact your score.
Maintain your oldest credit cards to preserve credit history length, even if you rarely use them. Use them occasionally for small purchases to keep them active.
Limit applications to 3-4 annually maximum to minimise enquiry impact on your scores.
Under CCR, 24 months of consistent on-time payments significantly improves scores. This is particularly beneficial for Australians rebuilding credit after financial difficulties.
Buy Now Pay Later services face dramatic regulatory changes from June 2025, coming under the National Consumer Credit Protection Act. Previously operating outside traditional credit rules, BNPL providers must now conduct credit checks and report payment behaviour to credit bureaus.
This closes a significant gap where consumers could accumulate substantial BNPL debt invisible to traditional lenders.
Financial hardship reporting also changed in July 2022. Hardship arrangements now appear as special flags on credit reports but cannot be used to calculate credit scores and disappear after 12 months instead of the standard 24.
Contrary to popular belief, several factors don't directly impact Australian credit scores:
Error corrections take 1-2 months once disputed. Payment history improvements show results in 3-6 months of consistent behaviour.
Major score rebuilding after defaults or bankruptcy requires 12-24 months of excellent financial habits, with gradual improvement as negative items age.
The most effective approach combines immediate utilisation optimisation with sustained payment consistency over time.
Never pay credit repair companies. Legitimate credit improvement services are available for free through ASIC MoneySmart or the National Debt Helpline (1800 007 007).
These companies cannot remove accurate negative information despite marketing claims, and charge for services available at no cost through government resources.
Understanding and actively managing your credit score is essential in Australia's high-debt economy. With the right knowledge and consistent habits, most Australians can achieve and maintain good credit scores that open doors to better financial opportunities.
