Australia has no single minimum credit score for a home loan. Each lender sets its own policy and assesses your credit report alongside your ability to repay.
A score quoted online is useful only when you know the bureau, its scale and the lender’s rules. A strong number cannot cancel out a recent default.
No Single Minimum Score Across Lenders
The credit score needed for a mortgage depends on the lender and the rest of your application. Figures such as 620 often come from overseas lending rules and are not Australian home-loan minimums.
A score below a lender’s policy can mean a specialist lender, tighter criteria or a higher interest rate. It can also mean delaying the application while you improve your position.
A credit score of 600 does not automatically rule out a home loan. A specialist lender may consider the application if its credit policy, income assessment and security requirements are met. The bureau and report details matter, and no published score guarantees acceptance.
A good score for mortgage purposes is one that meets the chosen lender’s policy alongside a satisfactory full application. A bureau’s “good” band describes its own model. The lender can apply a different cut-off or decline the file for another reason.
A credit check sits inside the wider home-loan eligibility assessment. Your income, deposit and existing commitments still affect the outcome.
What a Credit Score Measures
A credit score summarises the credit behaviour recorded in your credit report. Australia has two consumer credit reporting bodies, Equifax and Experian. Each calculates its own score from its own file.
These five factors help explain what a lender sees, although Australian bureau models do not assign them universal weights.
- Repayment history shows whether you meet scheduled repayments.
- Credit utilisation describes how much available credit you use. Lenders can assess this through statements, while bureau reports record credit limits and repayment information.
- Length of credit history shows how long accounts have been managed.
- Credit mix shows the types of borrowing you have. Taking out extra debt solely to create a mix adds costs and enquiries.
- Recent enquiries show applications for new credit. Several applications close together can raise concerns about reliance on borrowing.
A credit rating for a mortgage usually means the bureau credit score. A lender’s internal risk grade is its own assessment, using credit-report data and other application information. The bureau’s band and the lender’s grade are not interchangeable.
CreditorWatch is a commercial credit reporting business that reports on companies. Equifax and Experian hold the consumer credit files a home lender checks for an individual applicant.
Read the report behind the score. A reporting body can hold different information from the other, and a lender can calculate its own score.
Equifax and Experian Score Ranges
Equifax and Experian both publish Australian consumer score scales from 0 to 1,200.
Older Experian guides use a scale ending at 1,000. Use the scale printed on your report when interpreting a number or comparing it with an older result.
The former illion consumer bureau became part of Experian in 2026. Experian’s combined report contains the information previously held by both businesses. You no longer need separate illion and Experian reports. To improve a former illion score, work on your Experian file using the same steps as any other score.
Even when the maximum is the same, the two bureaus use different calculations. A score of 700 from Equifax does not carry the same band or meaning as 700 from Experian.
Reading the Score Bands
Score bands describe a bureau’s assessment of risk. Their names and cut-offs differ, so read the band against the correct bureau and scale.
| Band | Equifax Consumer Score | Experian Consumer Score |
|---|---|---|
| Lowest band | Below average: 0 to 459 | Low: 0 to 299 |
| Next band | Average: 460 to 660 | Fair: 300 to 499 |
| Good | 661 to 734 | 500 to 699 |
| Very good | 735 to 852 | 700 to 799 |
| Excellent | 853 to 1,200 | 800 to 1,200 |
These are the consumer bands published by Equifax and Experian. They are not lender approval thresholds.
Experian describes its 500 to 699 band as average and 700 to 799 as above average. It does not publish a single national average score.
Consider a hypothetical credit score of 650. The current Equifax consumer scale labels it “average”, within 460 to 660. Experian calls 650 “good”, within 500 to 699 on its current consumer scale. Both scales end at 1,200, but their bands differ.
First identify the bureau and the scale printed on the report. Then read that bureau’s band and assess the lender’s policy against the full file. A score of 650 is not an Australian home-loan approval threshold.
Prime lending generally suits stronger credit files. Near-prime products can cater for applicants outside standard criteria, while specialist lenders consider more adverse histories at risk-based prices.
Those lending categories do not have universal bureau-score boundaries. An applicant in a middle band needs a policy assessment, rather than an assumption that a particular lender tier will approve them.
How Scores Affect Approval and Pricing
A stronger credit score can support better pricing, but approval depends on the full file. Lenders examine recent defaults and enquiry clusters as well as the number.
For example, two applicants with the same score can have different outcomes. One may have a recent unpaid default while the other has a shorter history with reliable repayments.
Compare the lender’s credit policy and the applicant’s ability to meet repayments before judging the rate. A high score alone does not guarantee approval or the lender’s lowest advertised price.
How Lender Credit Overlays Change the Outcome
Lender credit overlays are the lender’s additional rules for accepting a credit file. A bureau band cannot tell you whether a particular default fits those rules.
For brokers, record each default’s listing date, amount and paid or unpaid status. Compare those details with the lender’s policy and record the policy version used.
Check how that policy treats recent enquiries and hardship arrangements. Establish what caused the hardship and whether the applicant can now afford the proposed loan.
Financial hardship information cannot be used to calculate a bureau credit score. It can still appear on the report, so separate the score from the lender’s assessment of present circumstances.
When a file falls just below a lender’s criteria, use the guide to approvals with borderline credit scores for placement strategy.
Credit Utilisation
Credit utilisation is the balance you use as a share of your available limit. A $2,000 balance on a $10,000 card uses 20% of that limit.
