illion was an Australian credit reporting body, now part of Experian, whose consumer and commercial credit files still sit behind many lending decisions.

Also known as: illion Australia, illion credit bureau, illion credit report

Key points

  • illion is now part of Experian. Australia has two main credit reporting bodies, Experian and Equifax, where it once had three.
  • illion.com.au now redirects to Experian, so requests for a report, a score or a correction go through Experian.
  • Files draw on credit providers, court and public records, default listings, bankruptcy notices and the enquiries lenders make.
  • Each bureau scores on its own model and scale, so an Equifax number will not match the one you saw from illion.
  • You can request your report, dispute an error and escalate to the OAIC under the Privacy Act and the Privacy (Credit Reporting) Code.

Frequently asked questions

Is illion still a credit bureau?

Not as a separate one. illion is now part of Experian, and illion.com.au redirects there. Australia has two main credit reporting bodies, Experian and Equifax. Data that sat in an illion file is handled by Experian, under the same Privacy Act rules.

How do I get my illion credit report now?

Request it from Experian. You are entitled to a free credit report from each credit reporting body every 3 months, and again after a credit refusal or a correction. Have identification and any earlier address ready before you request the file.

How long does a default stay on my credit file?

Default listings are typically retained for around five years from the date of the listing. Repayment history is commonly held for 24 months, financial hardship information for 12 months, and court judgments and insolvency records for a similar period to defaults.

How do I fix an error on my credit report?

Lodge a dispute with the credit reporting body, explain what is wrong and attach evidence such as statements, receipts or court documents. The investigation is dealt with within 30 days. If a lender supplied the data the dispute goes back to them, and unresolved matters can go to AFCA or the OAIC.

Will checking my own credit report affect my score?

No. Checking your own file does not affect your score. Applications for credit leave an enquiry that other lenders can see for a period, which is why several applications in a short stretch can read as higher risk.
