Australian Credit Score Ranges: What Your Number Actually Means

Quick Answer: Australia has three credit bureaus, each with its own scoring scale. Equifax scores range from 0–1,200: Below Average (0–459), Average (460–660), Good (661–734), Very Good (735–852), Excellent (853–1,200). Experian scores range from 0–1,000: Below Average (0–549), Fair (550–624), Good (625–699), Very Good (700–799), Excellent (800–1,000). Illion scores range from 0–1,000 with similar bands. A "good" credit score for home loan approval at mainstream lenders generally requires above 650–700 on most bureau scales. A single default typically drops a score by 80–200 points and can push a "Good" rating into "Below Average" — making mainstream lender approval unlikely. Defaults can sometimes be legally removed under the Privacy Act 1988 before their 5-year expiry, which can restore 100–300 points and restore lending eligibility.

Your credit score is a number — but knowing the number without knowing the scale it sits on is like knowing a temperature without knowing if it's Celsius or Fahrenheit. Australia has three separate credit bureaus, three separate scales, and three separate sets of score bands. Understanding which bureau you're looking at and what your number means on that scale is the starting point.

The Three Australian Credit Bureau Score Systems

Equifax (formerly Veda) Australia's largest credit bureau. The Equifax score runs from 0 to 1,200.

Most major Australian banks and mortgage lenders access Equifax files. The Equifax score is the one most commonly referenced in home loan assessments.

Experian Growing coverage across Australian lenders, particularly non-bank and fintech lenders. Scale runs 0 to 1,000.

Illion (formerly Dun & Bradstreet) Strong coverage with telcos, utilities, and some financial institutions. Scale runs 0 to 1,000 with bands similar to Experian.

What Lenders Actually Look At

Lenders don't just look at your score number — they look at your full credit file. The score is a summary indicator; the file behind it reveals what's actually happening. Two people can have the same score for very different reasons, and lenders can see the difference.

A score of 620 built from a clean file with recent enquiries from loan applications looks very different to a score of 620 that includes an unpaid default from 2022 that has partially aged. The first person may be approved at standard rates; the second will likely be declined by mainstream lenders regardless of the numeric score.

For home loans specifically, most mainstream lenders require a minimum score and a clean file — no current defaults or judgments. The score threshold varies by lender, but typically:

Mainstream lenders (big 4 banks, major non-banks): Generally require 650–700+ on Equifax scale and a clean file. A single active default typically triggers a decline regardless of score.

Mid-tier lenders: May consider scores from 600+ but scrutinise the file detail, particularly default amounts and recency.

Specialist/non-conforming lenders: Accept scores below 600 and files with defaults, at significantly higher interest rates.

How a Default Changes Your Score

A single default is the most damaging single event that can appear on a credit file. The score impact depends on the amount, recency, and your existing score profile:

The recovery timeline assumes no professional intervention — natural score improvement from aged defaults is slow and limited while the listing remains active.

What Improves Your Credit Score Naturally

For Australians with a clean or near-clean file who want to build their score, the key factors:

Repayment history (most impactful): Under Comprehensive Credit Reporting (CCR), lenders now report your repayment history monthly. Two years of consistent, on-time payments across all credit accounts builds a strong positive record. Conversely, any late payments are recorded.

Credit enquiries (moderately impactful): Each loan application creates a hard enquiry that temporarily reduces your score. Multiple simultaneous applications — particularly common in home loan shopping — create multiple enquiries that compound. Space applications out where possible.

Credit utilisation: High balances relative to credit limits reduce your score. Keeping credit card balances below 30% of the limit at statement time has a positive effect.

Age of credit history: Longer average account age is positive. Closing old accounts reduces average age.

Account diversity: Having different types of credit (home loan, credit card, personal loan) contributes positively to score calculation.

The Single Fastest Way to Improve a Damaged Score

For Australians with a default or serious negative listing, none of the above behaviours will meaningfully move the score while that listing is active. The default suppresses everything else.

Removing a default — through a legal dispute under the Privacy Act 1988, when procedural breach grounds exist — is the single fastest improvement mechanism available. Typical score improvements from a single default removal range from 100 to 300 points on the Equifax scale. This is achieved in 30 to 90 days in most ACS cases, versus 4–5 years of natural expiry.

Real Story: Score From 488 to 661 in 52 Days

Sean, a plumber from Cairns, checked his Equifax score through ClearScore and got 488 — well into "Below Average" territory. He'd been declined for a ute loan he needed for a new business contract. ClearScore showed the culprit: a $1,100 Optus default from 2021.

Sean contacted Australian Credit Solutions. Our assessment found that Optus had sent the Section 21D notice to an address Sean had vacated 15 months before the listing, despite Sean having updated his contact details through the Optus app. Privacy Act 1988 breach.

The default was removed in 52 days. Sean's Equifax score moved from 488 to 661 — shifting from Below Average to Good. The ute loan was approved at standard rate within two weeks.

The number on ClearScore told him there was a problem. Removing the default fixed it.

Frequently Asked Questions

What is a good credit score in Australia? A good credit score in Australia varies by bureau. On the Equifax scale (0–1,200), "Good" is 661–734. On the Experian scale (0–1,000), "Good" is 625–699. For mainstream home loan approval, most lenders prefer scores above 650–700 on the Equifax scale combined with a clean credit file — no active defaults or judgments.

Why do I have different scores with different bureaus? Different credit providers report to different bureaus. Your Equifax file may contain accounts that your Experian file doesn't, and vice versa. A default listed with one bureau doesn't automatically appear on the others. This is why checking all three bureaus is important — a default may be dragging one score down while the others appear clean.

What is the highest possible credit score in Australia? The maximum Equifax score is 1,200. The maximum Experian and illion scores are each 1,000. These maximum scores are rarely achieved in practice — they represent a profile with many years of clean credit history, no enquiries, low balances, and no negative listings of any kind.

How much does a default reduce my credit score? A default typically reduces an Equifax score by 80 to 300 points depending on the amount and your existing profile. A single default can move a score from "Good" to "Below Average" — which is why removal is so impactful. The reduction occurs immediately when the listing appears; recovery without removal is slow and takes 4–5 years post-expiry.

Can I check my credit score for free in Australia? Yes. You can check your Equifax score through ClearScore or GetCreditScore (free, Equifax data). Your Experian score is available through Credit Savvy (free). Your illion score is available through creditreport.com.au. You're also entitled to a free full credit report from each bureau once per year, plus a free report within 90 days of being declined for credit.

Does checking my own credit score lower it? No. Checking your own credit score is a "soft enquiry" and has zero impact on your credit score or file. Only credit applications (hard enquiries from lenders) affect your score.

Know Your Number — Then Fix It

Understanding your credit score range is step one. Step two, if the number is where it needs to be, is understanding which negative listing is suppressing it — and whether it's removable.
