Your credit score in Australia is calculated using data held by one or more of the three credit reporting bodies: Equifax, Experian, and illion. Since comprehensive credit reporting (CCR) was introduced, lenders can see not just your negative information (defaults, bankruptcies) but also positive data — how consistently you make repayments.
Understanding what actually moves your score is the first step to improving it.
What’s Actually in Your Credit File
Under CCR, your file contains:
- Personal information — name, DOB, address history
- Credit enquiries — every time you apply for credit, it’s recorded
- Account information — open credit accounts, their limits, and repayment history
- Defaults and serious credit infringements — unpaid debts, court judgments
- Bankruptcy or debt agreements
The repayment history section is the most significant change from the old negative-only system. Lenders can now see 24 months of repayment data — whether you pay on time, on time most of the time, or consistently late.
Check Your Score First
You’re entitled to a free credit report from each reporting body once a year. Equifax and illion both offer free score checks via their consumer portals. CreditSmart.org.au (ASIC’s resource) links to all three.
Check for errors before doing anything else. Incorrect defaults, outdated information, or credit enquiries you didn’t authorise all require a dispute process — but they’re common, and fixing them is the fastest possible credit improvement.
The Highest-Impact Actions
Pay every bill on time. Under CCR, on-time repayments now positively contribute to your score. Missed payments — even a few days late — are reported. Set up direct debits for the minimum repayment on every credit account if you’re prone to forgetting.
Reduce your credit utilisation. Using a high percentage of your available credit limit signals risk. Keeping usage below 30% of your limit is generally considered good; below 10% is ideal. Paying down credit card balances (rather than just the minimum) is the fastest way to improve this.
Limit new credit applications. Every credit enquiry is recorded and multiple enquiries in a short period signals desperation or financial stress to lenders. Don’t apply for new cards, loans, or phone plans unless you need them. If you’re shopping for a home loan, do your rate research first and then apply to your preferred lender — don’t make multiple applications to compare.
Don’t close old accounts unnecessarily. Length of credit history matters. An old credit card with a low limit and zero balance is doing more good sitting open than being cancelled.
How Long Negative Items Stay
| Item | How Long on File |
|---|---|
| Credit enquiry | 5 years |
| Default | 5 years |
| Court judgment | 5 years |
| Serious credit infringement | 7 years |
| Bankruptcy | 5 years (or 2 years after discharge) |
The good news: each month of consistent positive repayment behaviour starts building a counterweight to historical negatives.
The Timeline
Significant score improvements take 6–12 months of consistent behaviour. Quick fixes are rare (they mostly involve correcting errors). Start with your credit report, address any errors, set up automatic payments, and be patient.
