Illion Credit Score Australia 0-1,000 — Telco Bureau (2026)

Quick Answer: Illion is one of Australia's three credit bureaus — alongside Equifax and Experian. The Illion credit score range is 0–1,000, with these bands:

• 800–1,000: Excellent
• 700–799: Great
• 500–699: Good (Australian average sits around 580)
• 300–499: Room for Improvement
• 0–299: Below Average

Illion is the bureau Australian telcos and utilities report to — Telstra, Optus, Vodafone, AGL, Origin, EnergyAustralia, Aussie Broadband. Most car finance brokers and dealer finance arms pull Illion first. This means a telco or utility default from years ago — completely paid off, sitting on your file — can still block your car loan even when your Equifax file looks healthy.

Most Australians have heard of Equifax. Far fewer know that Illion — Australia's third major credit bureau — may hold an entirely different picture of their credit history. And for one specific situation, Illion is the bureau that matters most: car loans, phone plans and energy account approvals.

This guide explains everything about your Illion file: the 0–1,000 score range, who reports to Illion, who pulls it, and what to do if a listing on your Illion file is blocking finance.

What Is Illion?

Illion (formerly Dun & Bradstreet Consumer, rebranded in 2018) is a credit bureau operating across Australia and New Zealand. It collects consumer credit data from lenders, telcos and utilities, maintains an independent credit file for every Australian adult with a credit history, and generates credit scores used by Australian lenders in their credit assessment processes.

Illion operates completely separately from Equifax and Experian. The information on your Illion file is independent of what's on your other bureau files — and your Illion credit score is calculated using Illion's own proprietary algorithm.

Free Illion file: creditreport.com.au — under the Privacy Act 1988 every Australian is entitled to one free Illion credit file every 3 months.

Illion Credit Score Range — Full 0–1,000 Band Table

The Illion credit score runs from 0 to 1,000 with five distinct bands:

The Australian adult average Illion score is approximately 580 — sitting in the lower-mid "Good" band.

Comparing Illion to Equifax and Experian

Same person, three different scores — because each bureau holds different data and uses a different scoring formula:

A score of 700 means very different things across bureaus. On Equifax it's "Good"; on Experian it's "Very Good"; on Illion it's "Great." For a complete comparison see our Equifax vs Experian vs Illion guide.

Who Reports to Illion in Australia?

Illion's data subscriber network is heavy on telcos, utilities and consumer finance. The major Illion-reporting credit providers in Australia:

Telecommunications

• Telstra — Australia's largest mobile network
• Optus — major mobile and internet
• Vodafone (TPG Telecom)
• TPG broadband and mobile
• Aussie Broadband
• Dodo, iiNet, Belong and most MVNOs

Energy and utilities

• AGL — major electricity and gas
• Origin Energy — major electricity and gas
• EnergyAustralia
• Red Energy, Alinta Energy, Lumo Energy
• Most state-based water authorities (some)

Finance and lending

• Many car finance brokers and dealer finance arms
• Several BNPL providers (overlap with Experian)
• Some non-bank personal loan providers
• Debt collection agencies (CCC, Credit Corp, Panthera, Lion Finance, etc.)
• Some smaller credit unions

Other

• Some insurance providers
• Some rental property assessment platforms

The pattern: if you've ever had drama with a phone bill, energy account, internet plan or paid debt that went to a collector, it's almost certainly on your Illion file — even if your Equifax file shows nothing.

Who Pulls Illion in Australia? (This Is the Critical Bit)

Knowing who reports to Illion is half the picture. The bigger question is who looks at your Illion file when assessing your application.

Heavily Illion-dependent (Illion is primary or co-primary bureau):

• Car finance brokers (almost universally)
• Dealer finance arms (Toyota Finance, Ford Credit, Hyundai Finance, etc.)
• Most consumer finance providers
• Most BNPL providers (alongside Experian)
• Telco postpaid applications
• Energy account openings
• Rental property applications (some agencies)

Illion as secondary check:

• Major banks pulling supplementary data on home loan applications
• Mortgage brokers running pre-assessment three-bureau checks
• Personal loan providers

Rarely uses Illion:

• The four major banks for home loan primary assessment (Equifax is primary)
• Some fintech lenders (Experian-primary)

The takeaway: if you're applying for car finance, a phone plan, or an energy account, your Illion file is almost certainly the file that decides. If you're applying for a home loan at a major bank, Illion is the second check.

Why You Must Check Illion Separately From Equifax

Many Australians check their Equifax score (via ClearScore or GetCreditScore), find it acceptable, and assume their credit health is fine. Then they're declined for a car loan and don't understand why.

The cause is almost always a default on Illion that doesn't appear on Equifax — most commonly a telco or utility default.

Why does this happen? Because credit providers choose which bureaus they report to. Many telcos and utilities only report to Illion. So:

• The default exists on your Illion file
• The car finance broker pulls Illion (their primary bureau)
• The default triggers an automatic decline
• Your Equifax file remains unaware

This is one of the most common sources of mystery declines in Australia. The fix isn't applying to more lenders (which just stacks enquiries). The fix is finding out what's on your Illion file.

How to check your Illion score for free

Three ways:

1. Direct from Illion: creditreport.com.au — one free file every 3 months
2. Free monitoring: Some banking apps include Illion data (varies by bank)
3. As part of an ACS free assessment: we pull all three bureau files within 48 hours

What Damages Your Illion Score Most?

The biggest score suppressors on the Illion 0–1,000 scale — ranked by impact:

1. Telco defaults. Illion weights telco defaults heavily because telcos are major Illion subscribers. A $300 unpaid Optus default can drop an Illion score by 150–250 points.

2. Utility defaults. AGL, Origin, EnergyAustralia defaults are common on Illion files and equally damaging.

3. Court judgements. Maximum impact across all bureaus, including Illion — typically 200–350 point drop.

4. Credit collection accounts. Debt collectors (CCC, Credit Corp, Panthera, Lion Finance) report aggressively to Illion. A debt sold to a collector can appear as a separate negative entry.

5. Multiple recent enquiries. 4+ hard enquiries in 12 months is a red flag in Illion's scoring model.

6. Late payments under CCR. Comprehensive Credit Reporting data is shared with Illion. Late payment status codes stay 2 years.

Real Story: An AGL Default Hidden From Equifax Cost a Sydney Marketing Manager Two Personal Loan Approvals

A 31-year-old marketing manager from Newtown in Sydney had checked her Equifax score — 641, "Good" band. She assumed her credit was fine and applied for a personal loan to consolidate a credit card balance.

She was declined. She applied at a second lender — declined again. Both lenders had pulled her Illion file (which she hadn't checked).

Australian Credit Solutions pulled all three bureaus in the free 48-hour assessment. The Illion file showed:

• Equifax score: 641 (Good)
• Illion score: 489 (Room for Improvement)
• The cause: a $790 AGL energy default from 2022 that had been listed on Illion but never reported to Equifax

The AGL default had been listed in breach of the Credit Reporting Code — the Section 21D pre-listing notice had been sent to her former Glebe address despite her updating her address with AGL six months prior to the listing.

ACS lodged the formal dispute. AGL removed the default on day 38. Her Illion score moved from 489 to 601 — Room for Improvement to Good. The personal loan was approved the following month at standard rates.

Equifax never had the problem. Illion did. She would never have known without a three-bureau check.

Can a Listing Be Removed From Illion?

Yes. Under the Privacy Act 1988 (Cth) Part IIIA, any listing on any Australian credit bureau — including Illion — can be challenged for removal if it was recorded in breach of the legislation or the Credit Reporting Code.

Common removal grounds for Illion listings:

• Section 21D pre-listing notice sent to a wrong address (very common with telco and utility defaults — customers move and the notice goes to the old address)
• Incorrect amount listed (the disputed amount differs from the actual amount owed)
• Default listed during an active dispute (e.g., a Telecommunications Industry Ombudsman complaint or Energy and Water Ombudsman complaint)
• Statute-barred debt (debts older than 6 years under most state Limitation of Actions Acts)
• Identity fraud (account opened in your name without your authorisation)

The dispute is lodged with the credit provider that listed the entry — not directly with Illion. The credit provider then instructs Illion to remove the listing if the dispute is upheld. Illion is required to act on the credit provider's removal instruction.

If the credit provider refuses, the dispute can be escalated to AFCA (afca.org.au), whose determination is legally binding.

Australian Credit Solutions handles the full process under solicitor supervision — Principal Solicitor Elisa Rothschild BA/LLB. 98% success rate on accepted cases. No Win No Fee — success fees only payable when the listing is actually removed.

Frequently Asked Questions

What is the Illion credit score range in Australia? The Illion credit score range in Australia is 0 to 1,000. The bands are: 0–299 Below Average; 300–499 Room for Improvement; 500–699 Good; 700–799 Great; 800–1,000 Excellent. The Australian adult average Illion score is approximately 580, sitting in the lower-mid "Good" band. Illion uses a different scoring formula to Equifax (which uses a 0–1,200 scale) so the scores aren't directly comparable.

What are the Illion credit score range bands in Australia? The five Illion credit score bands in Australia: 0–299 Below Average (mainstream lenders decline). 300–499 Room for Improvement (specialist lenders only). 500–699 Good (most lenders open, Australian average sits here). 700–799 Great (strong position, standard rates). 800–1,000 Excellent (top tier, best rates and offers). A score of 500+ on Illion is considered acceptable for most consumer finance applications.

Is Illion the same as Equifax in Australia? No. Illion and Equifax are completely separate, independently operated credit bureaus. They maintain their own credit files, have different lender subscriber networks, and use different scoring algorithms. The information on your Illion file may be substantially different from your Equifax file — particularly for telco and utility defaults, which are heavily reported to Illion. Always check all three bureaus for a complete credit health picture.

How do I check my Illion credit report in Australia for free? Access your free Illion credit report at creditreport.com.au. You're entitled under the Privacy Act 1988 to a free Illion credit file at least once every 3 months. The report includes your full credit file — defaults, repayment history, enquiries, and Illion credit score. You'll need to verify your identity with personal details (driver's licence, Medicare card, or passport). Free access is also available within 90 days of being declined for credit.

Why is my Illion score different from my Equifax score? Your Illion and Equifax scores differ for two reasons. First, different credit providers report to different bureaus — your telco default may appear on Illion but not on Equifax; your home loan may appear on Equifax but not on Illion. Second, even with identical underlying data, Illion and Equifax use different proprietary scoring algorithms that weight factors differently. The scales are also different (Illion 0–1,000, Equifax 0–1,200). Your Illion and Equifax scores will almost always differ — sometimes by hundreds of points.

Which Australian lenders use Illion? Lenders that primarily use Illion in Australia: most car finance brokers and dealer finance arms (Toyota Finance, Ford Credit, Hyundai Finance, etc.), telcos for postpaid plan applications (Telstra, Optus, Vodafone), energy retailers (AGL, Origin, EnergyAustralia), some BNPL providers, and many non-bank personal loan providers. The four major Australian banks (CBA, ANZ, NAB, Westpac) primarily use Equifax for home loan assessments but often pull Illion as a secondary check.

Can I dispute a default on my Illion credit file? Yes. You can dispute any incorrect or unlawfully listed entry on your Illion credit file under the Privacy Act 1988 (Cth) Part IIIA — the same legislation that governs disputes at Equifax and Experian. The dispute is lodged with the credit provider that listed the entry (not directly with Illion as a first step). Common dispute grounds include: incorrect Section 21D pre-listing notice, wrong amount, default listed during an active dispute, or statute-barred debt. If the credit provider refuses, escalate to AFCA. Australian Credit Solutions handles the full dispute process — ASIC ACL 532003, lawyer-led, No Win No Fee.

Can a telco default on my Illion file be removed? Yes — and telco defaults are among the most commonly removable listings on Illion files. The most common ground for removal is the Section 21D pre-listing notice was sent to a wrong address — extremely common with Telstra, Optus and Vodafone defaults where the customer has moved and updated their address with the telco but the default notice still went to the old address. The default is procedurally invalid and removable. Australian Credit Solutions removes telco defaults on Illion regularly — typically within 30–60 days.

Can a utility default (AGL, Origin) on my Illion file be removed? Yes. Utility defaults from AGL, Origin Energy, EnergyAustralia and other major Australian energy providers can be removed from your Illion credit file under the Privacy Act 1988 if they were listed in breach of the law. Common grounds: Section 21D notice sent to a wrong address (very common when customers move house); the default was listed while an Energy and Water Ombudsman complaint was active; or the disputed amount differs from the listed amount. Australian Credit Solutions handles utility defaults regularly across all states.

What's a good Illion credit score for a car loan in Australia? For a car loan in Australia, most mainstream lenders want an Illion score of 500+ combined with a clean file (no active defaults or court judgements). Many car finance brokers pull Illion as their primary bureau — so the Illion score is critical for car finance specifically, regardless of what your Equifax shows. Scores 500–699 typically get standard rates; 700+ unlocks the best dealer finance offers. Below 500, specialist car finance is available but at 4–7% above standard rates.

Is 600 a good Illion credit score in Australia? Yes — 600 is a Good Illion score in Australia. It sits in the "Good" band (500–699) which is the Australian average range. A score of 600 indicates acceptable credit health to most mainstream lenders for personal loans, car loans, credit cards and most consumer finance. For the best rates and offers, aim for 700+ ("Great" band) or 800+ ("Excellent" band). If your Illion score is below 500 — Room for Improvement or Below Average — a specific listing on your file is typically suppressing it.

Does the Illion credit score affect my home loan in Australia? Indirectly, yes. The four major Australian banks (CBA, ANZ, NAB, Westpac) use Equifax as their primary bureau for home loan assessments, but they often pull Illion as a secondary check — particularly to catch telco and utility defaults that wouldn't appear on Equifax. A poor Illion score with an active default can cause home loan rejections even when your Equifax score looks healthy. This is why ACS always assesses all three bureaus before any major finance application.

How often does Illion update my credit score? Illion updates your credit score whenever your credit file changes — typically within 14 days of a credit provider reporting new information (a new account, a missed payment, a default, an enquiry, or a default removal). For most Australians, the Illion score updates 1–3 times per month as data flows in from credit providers. You can check your updated score at creditreport.com.au once every 3 months for free.
