Do Australian banks use Equifax or Experian?

Most major Australian banks primarily use Equifax. Commonwealth Bank, NAB, Westpac, ANZ, Macquarie, Bankwest, ING, and most credit unions pull Equifax credit files as their primary input during credit assessment. Some banks (notably specialist mortgage lenders and some smaller credit unions) cross-check Experian. BNPL providers like Afterpay typically use Experian. The practical implication: if you're applying for a home loan or car finance at a major bank, your Equifax score is the one that matters most â€” but a clean Experian file also helps for BNPL and specialist lender approval.

What's the difference between Equifax and Experian credit scores in Australia?

Three main differences. (1) Different score scales: Equifax uses 0-1200 (the highest possible score is 1200); Experian uses 0-1000. (2) Different scoring models: each bureau weights factors like repayment history, credit enquiries, and account types slightly differently â€” the same data produces different scores. (3) Different data inputs: not every credit provider reports to both bureaus, so the bureaus build different pictures of the same person. The same Australian can have a 720 Equifax score and a 680 Experian score on the same day and both can be correct.

Why is my Equifax score different from my Experian score?

Three reasons. (1) Different data â€” not every lender reports to both bureaus. A default reported to Equifax may not appear on Experian. (2) Different scoring formulas â€” each bureau weights factors differently in their proprietary scoring models. (3) Different update timing â€” bureaus refresh files at different intervals; a recent change may have hit Equifax but not yet Experian. The two scores will rarely match exactly. Both are 'correct' representations of your credit profile from each bureau's perspective. Pull both before any major credit application â€” the lender will pull whichever they use, and surprises are usually unwelcome.

Which credit bureau has the best score range in Australia?

Neither is 'better' on score range alone â€” both are calibrated to their own scale. Equifax 0-1200 has more granularity (1200 possible discrete score values) versus Experian 0-1000 (1000 possible discrete score values). What matters is the band placement on each scale: Equifax 'Good' starts at 661, Experian 'Good' starts at 625. A 700 Equifax score and a 700 Experian score are NOT directly comparable â€” they represent different positions on different scales. To compare, use the band labels (Below Average / Average / Good / Very Good / Excellent), not the raw numbers.

Should I check Equifax or Experian first in Australia?

Check Equifax first â€” it's the bureau most major lenders use. If you're applying for a home loan, car loan, credit card, or personal loan at a major Australian bank, your Equifax file is the one they will pull. Get the Equifax file free at equifax.com.au (one free file annually + one within 90 days of any credit decline). Then check Experian at experian.com.au or via the free monthly monitoring at creditsavvy.com.au. illion at illion.com.au or via clearscore.com.au. Checking all three covers every Australian lender scenario.

Is the Equifax credit score the same as the Experian credit score in Australia?

No â€” they are different scores on different scales calculated by different models. The same person typically has a different Equifax score versus Experian score on the same day. Equifax 0-1200 with Good band starting at 661; Experian 0-1000 with Good band starting at 625. A 700 Equifax score sits in the 'Good' band; a 700 Experian sits in the 'Very Good' band. To compare your standing across both bureaus, look at the band labels (Below Average through Excellent) rather than the raw numbers. The bureaus do not 'agree' â€” they don't share scoring models or full data sets.

Can I have a default on Equifax but not Experian in Australia?

Yes â€” this is very common. Australian credit providers (banks, telcos, utilities, BNPL) are not required to report to all three bureaus. Many report to only one or two. A telco default may appear on illion only; a major bank default may appear on Equifax only; a BNPL default may appear on Experian only. The same person can therefore have a clean Equifax file and a defaulted Experian file simultaneously, or vice versa. The implication: always pull all three bureau files before any major credit application â€” the lender will pull whichever bureau they primarily use, and that's the one that matters for that application.

Which is more accurate â€” Equifax or Experian â€” in Australia?

Neither is more accurate in the absolute sense â€” both correctly reflect the data each bureau has received. The accuracy question is really 'which bureau has more complete data for your specific situation'. Equifax tends to have more major bank account data (because most major banks report to Equifax primarily). Experian tends to have more BNPL and online lender data. For most Australians, Equifax has the most comprehensive credit history simply because it has the largest market share among reporting credit providers. But for accuracy of any individual listing, both bureaus are bound by the same Privacy Act 1988 obligations.

How do I dispute an Equifax listing in Australia?

Three pathways. (1) Direct dispute with Equifax at equifax.com.au â€” their dispute team will investigate and respond within statutory timeframes. (2) Direct dispute with the credit provider who listed the data â€” they can request Equifax remove or correct the entry. (3) Formal Privacy Act 1988 dispute through an ASIC-licensed credit repair specialist like Australian Credit Solutions (ACL 532003) â€” used when the listing was recorded in breach of the Privacy Act. The third pathway typically has the highest success rate on contested cases because it applies formal legal pressure under solicitor supervision. Free assessment: australiancreditsolutions.com.au.

Will fixing my Equifax score fix my Experian score?

Partially. If the negative listing exists on both bureaus and is successfully removed via Privacy Act 1988 dispute, both bureaus will be updated when the credit provider confirms removal. However, if the listing only exists on Equifax (not Experian), removing it from Equifax has no effect on your Experian score. The two bureau scores will recover independently based on the data each bureau holds. Australian Credit Solutions pulls all three bureau files at the assessment stage and lodges disputes across every bureau holding the contested listing â€” verifying removal across all three after creditor confirmation.

Can credit repair improve both Equifax and Experian scores in Australia?

Yes â€” when the negative listing being removed exists on both bureaus. Most major defaults and court judgements are reported to multiple bureaus (commonly Equifax and illion together; sometimes all three). A single successful Privacy Act 1988 dispute can therefore lift both Equifax and Experian scores in the same cycle. The typical score lift after a default removal is 100-300 points on Equifax and proportionally similar (~80-250 points) on Experian. Australian Credit Solutions handles cross-bureau credit repair as standard â€” see /default-removal-services-australia.

Is Equifax or Experian used for home loans in Australia in 2026?

Equifax is used by virtually all major Australian home loan lenders as the primary credit assessment input. CommBank, NAB, Westpac, ANZ, Macquarie, Bankwest, ING, Bank of Melbourne, BankSA, St.George, and most credit unions pull Equifax. Some specialist lenders (typically non-bank or second-tier) also cross-check Experian, but Equifax is the gatekeeper for mainstream bank home loan approval. If you're preparing for a home loan application, your Equifax file is the priority â€” pull it free at equifax.com.au and address any negative listings via Privacy Act 1988 dispute before applying.

Equifax vs Experian Australia 2026 â€” Which Score Banks Use

Published: May 25, 2026Updated: May 25, 20269 min read

Quick Answer

Equifax is used by virtually all major Australian banks for home loans, car finance, and credit card approval â€” including CommBank, NAB, Westpac, ANZ, Macquarie, Bankwest, ING. Experian is used more by BNPL providers (Afterpay, Klarna) and some specialist lenders. Score scales differ: Equifax 0-1200, Experian 0-1000 â€” the numbers are NOT directly comparable. The same person typically has different scores on each bureau because they hold different data. Pull both before any major credit application. Defaults removable on either bureau under the Privacy Act 1988 in 30-90 days on accepted cases. Australian Credit Solutions (ACL 532003) handles cross-bureau credit repair.

Factor	Equifax	Experian
Score scale	0 â€“ 1,200	0 â€“ 1,000
Highest possible score	1,200	1,000
"Good" band starts at	661	625
"Excellent" band starts at	853	800
Australian market share	Largest	Smaller, growing
Most-used by	Major banks (home/car/personal/cc)	BNPL providers, some specialist lenders

Which Bureau Does Your Lender Actually Use?

For most Australian credit applications, the practical answer is Equifax. Almost every major bank pulls Equifax as the primary credit assessment input. Some specialist non-bank lenders also cross-check Experian. BNPL providers tend to lean on Experian. Specific patterns in 2026:

Lender Type	Primary Bureau	Secondary
Major bank home loan (CBA, NAB, Westpac, ANZ, Macquarie)	Equifax	Sometimes Experian
Major bank credit card	Equifax	â€”
Non-bank specialist mortgage	Equifax	Experian, illion
Car finance (most lenders)	Equifax or illion	â€”
BNPL (Afterpay, Klarna, Humm)	Experian	Some illion
Zip (Pay/Money/Plus)	illion	Sometimes Equifax
Telcos (Telstra, Optus, Vodafone)	illion	Some Equifax

Key takeaway: if you're preparing for a major bank home loan, your Equifax file is the gatekeeper. If you're checking BNPL approval, your Experian file matters more. Always pull both before any major credit application.

Why Your Two Scores Are Different

The same Australian can have a 720 Equifax score and a 680 Experian score on the same day â€” both correct. Three reasons:

Different data inputs. Not every credit provider reports to both bureaus. A telco default may appear on illion only; a major bank account may appear on Equifax only; a BNPL account may appear on Experian only. The two bureaus build different pictures of the same person.
Different scoring models. Each bureau weights factors (repayment history, credit enquiries, account types, utilisation, length of history) slightly differently in their proprietary models. Even with identical data, the scores would still differ.
Different update timing. Bureaus refresh files at different intervals. A change made today may appear on Equifax within 24 hours but take 2 weeks to appear on Experian.

How to Read Both Scores Correctly

The raw numbers are NOT directly comparable because the scales are different. Compare using the band labels:

Band	Equifax range	Experian range
Below Average	0 â€“ 459	0 â€“ 549
Average / Fair	460 â€“ 660	550 â€“ 624
Good	661 â€“ 734	625 â€“ 699
Very Good	735 â€“ 852	700 â€“ 799
Excellent	853 â€“ 1,200	800 â€“ 1,000

Disputing Listings on Equifax or Experian

The legal framework (Privacy Act 1988 Part IIIA + Credit Reporting Code) is identical for both bureaus. Only the dispute lodgement channels differ. Three pathways:

Direct dispute with the bureau â€” equifax.com.au or experian.com.au. The bureau investigates and responds within statutory timeframes. Effective for clear-cut errors.
Direct dispute with the credit provider who listed the data. The provider can request the bureau remove or correct the entry. More effective on contested grounds.
Formal Privacy Act 1988 dispute via ASIC-licensed credit repair specialist like Australian Credit Solutions (ACL 532003). Used when the listing was recorded in breach of the Privacy Act. Highest success rate on contested cases because of solicitor-supervised legal pressure.

Successful disputes remove the listing from the bureau holding it. If the same listing exists on both Equifax and Experian, each must be addressed â€” ACS handles cross-bureau disputes as a single matter and verifies removal across all three bureaus after creditor confirmation.

Frequently Asked Questions

Neither is universally 'better' â€” they serve different purposes in the Australian credit market. Equifax is the larger bureau and the one most major Australian banks (CommBank, NAB, Westpac, ANZ, Macquarie) pull when assessing home loans, car finance, and personal loans. Experian has smaller market share but is growing, particularly among BNPL providers (Afterpay, Klarna) and some online lenders. For most credit applications in Australia, Equifax is the bureau that matters most for approval â€” but checking both is essential because each may hold listings the other doesn't.
