Your credit score is a number that summarises your credit history — how reliably you have managed debt and credit products in the past. Lenders use it to assess the risk of lending to you. In Australia, three separate agencies calculate your score, and each uses a slightly different methodology and scale.


Key Takeaways

  • Australia has three credit reporting agencies: Equifax, Experian, and illion
  • Each uses a different scale — a “good” score means different things at each agency
  • Your score is based on your credit file, which records credit enquiries, accounts, repayment history, and negative events (defaults, bankruptcies)
  • You can access your credit report and score for free from each agency
  • Australia uses comprehensive credit reporting (CCR) — meaning repayment history (positive and negative) is now shared by lenders

The Three Credit Agencies in Australia

AgencyScore range“Good” score starts at
Equifax0 – 1,200~625 (Good), ~700 (Very Good), ~853 (Excellent)
Experian0 – 1,000~625 (Good), ~700 (Very Good)
illion0 – 1,000~500 (Average), ~700 (Good), ~800 (Excellent)

The different scales mean you cannot directly compare a score from Equifax with one from Experian. What matters is your rating band (e.g., Good, Very Good, Excellent) — not the raw number.

Most lenders use one or two of these agencies. You may have a different score at each agency depending on which lenders have reported your data.


What Is Comprehensive Credit Reporting (CCR)?

Australia introduced mandatory Comprehensive Credit Reporting (CCR) for the major banks from 2018–2019. Under CCR:

  • Lenders must share positive repayment history (not just negative events) with credit agencies
  • This allows someone with a clean repayment history to build a stronger credit file, even without defaults
  • It also means a missed payment is now recorded as a negative event on your file

Before CCR, Australian credit files mainly recorded negative events (defaults, bankruptcies). CCR made the system more like the US model, where your regular on-time payments count in your favour.


What Affects Your Credit Score

Positive factors

  • On-time repayments: consistently meeting minimum repayments on credit cards, loans, and buy now pay later
  • Long credit history: accounts that have been open for many years
  • Low credit utilisation: using a small proportion of your available credit limit
  • Stable addresses and employment (recorded on your file)

Negative factors

EventTypical impact on score
Late payment (30+ days overdue)Moderate to significant reduction
Default (serious overdue debt — $150+)Significant reduction; stays on file for 5 years
Court judgmentVery significant; stays for 5 years
BankruptcyVery significant; stays for 5–7 years
Multiple credit enquiries in a short periodModerate reduction
Account closed with a balance outstandingCan reduce score

Credit Enquiries

Every time you apply for credit (a loan, credit card, mortgage, car finance), the lender does a credit enquiry — and this is recorded on your credit file.

  • A single enquiry has a modest impact on your score
  • Multiple enquiries in a short period (e.g., applying to 5 lenders in a month) can reduce your score significantly
  • Lenders interpret multiple enquiries as a sign of financial stress or desperation for credit

Note: checking your own credit score does not affect your score. Only hard enquiries by lenders affect it.

Credit Score vs Credit Report

What it showsYour creditworthiness ratingAll accounts, enquiries, repayment history

How often it updatesMonthly or more frequentlyAs lenders report data

Your credit report is the underlying data. Your credit score is a derived summary of that data. It is worth checking both — especially before applying for a major loan.


FAQ

Does Australia use the same credit score as the US? No. FICO scores are used in the US. Australia uses proprietary models from Equifax, Experian, and illion. The principles are similar but the scales are different.

Can I dispute errors on my credit file? Yes. If you find inaccurate information on your credit report, you can dispute it directly with the credit reporting agency. They are required to investigate and correct genuine errors. You can also complain to the Australian Financial Complaints Authority (AFCA) if the dispute is not resolved.

How long do negative events stay on my file?

  • Defaults: 5 years from the date the default was listed
  • Court judgments: 5 years
  • Bankruptcy: 5 years from discharge (up to 7 years in some cases)
  • Enquiries: 5 years

Do utility bills affect my credit score? Unpaid utility bills can be listed as a default if the debt is $150+ and overdue by 60+ days and the provider has sent a notice. Regular on-time utility payments are not currently reported as positive data in Australia.
