What Credit Score Do You Need for a Home Loan in Australia?

Quick Answer: Most Australian lenders require an Equifax credit score of at least 660 (Good band) for a home loan. The big four banks — CBA, ANZ, Westpac and NAB — generally want 680 or above with no active defaults. Non-conforming lenders accept scores from around 500 but charge rates 2–4% higher. Under the Privacy Act 1988, a default listed without the required procedural notice can be professionally disputed and removed in 30–90 days, which often moves a score from the rejection zone into the mainstream approval band.

Your credit score sits at the front of every home loan application. Not because lenders rely on it alone — income, deposit, employment history and existing debts all matter — but because it's the first automated filter. Fall below a lender's threshold and the application doesn't get a human eye on it.

This guide sets out the exact score thresholds by lender type, explains why a default on your file often blocks approval more than a low score does, and shows you the realistic path to eligibility if your score isn't there yet. If you'd like to understand how credit scores work in Australia first, that's a useful starting point.

What Is the Minimum Credit Score for a Home Loan in Australia?

There is no single universal minimum — each lender sets its own policy — but as a working guide for 2026: most mainstream lenders want an Equifax score of at least 660, while the big four banks generally require 680 or above with no active defaults. The Office of the Australian Information Commissioner (OAIC) regulates what credit information lenders can access, which directly shapes the picture they see.

The table below gives indicative ranges across lender types. These are starting points — actual offers depend on deposit size, loan-to-value ratio, income stability and the specific entries on your file.

Even within these bands, the presence of a default listing often overrides the score. Many mainstream lenders apply an automatic-decline rule for any active default regardless of where the Equifax number sits.

Does Your Credit Score Affect Your Home Loan Interest Rate?

Yes — significantly. In Australia, home loan pricing is risk-based, and your Equifax credit score is one of the primary risk signals a lender uses. Borrowers in the Excellent band access the best available rates; borrowers in the Below Average band pay non-conforming rates that can be 2–4% higher. On a $500,000 loan over 30 years, a 3% rate premium adds approximately $290,000 in total interest. MoneySmart (moneysmart.gov.au) confirms that the rate difference between mainstream and non-conforming products is one of the largest single financial costs a borrower can face.

Moving from the Average band to Good — from, say, 620 to 680 — can unlock a mainstream rate where previously only non-conforming products were available. On a $500,000 loan over 30 years, that difference exceeds $250,000.

Why Does a Default Hurt Your Application More Than a Low Score?

A default on your credit file is often a harder barrier than a low score — because most mainstream Australian lenders run their assessment engines against specific negative entries before the Equifax number is even considered. An active default flags that a credit provider formally recorded a payment failure. Even a borrower with a score of 690 can be declined across every major bank if a default is sitting on the file.

Under the Privacy Act 1988 (Part IIIA), defaults are retained on your credit file for five years. During that period, they're visible to every lender who checks any of the three bureaus — Equifax, Experian and Illion. The score may have recovered; the default entry remains.

The critical question is whether the listing was lawful. Under the Privacy (Credit Reporting) Code 2025 (commenced 25 March 2025), a creditor must issue a Section 21D notice — a written warning to your last known address, giving you 14 days to respond — before listing a default. A missing, misaddressed or defective notice is a removable procedural breach. You have the right to dispute it under your rights under the Privacy Act. For a detailed look at how defaults interact with home loan approvals, see our guide on getting a home loan with a default.

How Quickly Can Removing a Default Lift Your Score?

Removing an unlawfully listed default through Australian Credit Solutions typically lifts an Equifax score into the home loan approval range within 30 to 90 days — because the credit reporting body is legally required under the Privacy Act 1988 to update your file within 5 business days of confirming a correction. In cases where the default was the primary negative entry, clients have seen scores improve by 80–130 points upon removal.

ACS achieves a 98% success rate on accepted cases. The 2% reflects cases where the listing was procedurally correct and cannot be challenged — we don't take those cases on. The 98% figure is a product of selectivity at intake, not a marketing promise. MoneySmart confirms that a clean credit file materially improves both approval chances and the rate you're offered.

Representative Example: Perth Client — Score 623 to 741, Approved by Commonwealth Bank

Details changed for privacy.

A dental hygienist in Perth had saved $110,000 over four years — more than 20% on a $490,000 property. Stable income. Her Equifax score sat at 623, dragged down by a $560 default from a gym membership listed 14 months earlier.

Her mortgage broker told her to wait three and a half years for the default to expire, or take a non-conforming rate of 9.1% p.a. — adding approximately $229,000 in extra interest over 30 years.

During her ACS assessment, we found the gym had never issued the required Section 21D pre-listing notice under the Privacy Act 1988. We lodged the dispute. The gym's parent company acknowledged the breach within 18 days. The default was removed on day 29.

Her Equifax score moved from 623 to 741. Her mortgage broker reapplied through Commonwealth Bank — approved at 6.19% p.a. Compared to the 9.1% non-conforming quote, the interest saving over 30 years was approximately $229,000. She only paid when we succeeded.

How Do You Raise Your Credit Score to Qualify for a Home Loan?

Australian Credit Solutions recommends a structured approach to building home loan eligibility. Under the Privacy Act 1988, you're entitled to a free credit report from all three bureaus — Equifax (equifax.com.au), Experian (experian.com.au) and Illion (creditreport.com.au) — once per year, or at any time if a dispute is open.

1. Get all three credit reports — Equifax, Experian and Illion may carry different information. A lender can check any bureau; you need to know what all three say.
2. List every negative entry — defaults, hard enquiries, missed repayment history (CCR data) and court judgements.
3. Assess each entry for removal grounds — no Section 21D notice, disputed amount, wrong address, or statute-barred debt.
4. Challenge removable entries professionally — lawyer-led disputes through ACS typically resolve in 30–90 days. Our default removal services cover the full dispute and escalation process.
5. Stop all new credit applications — every hard enquiry stays on file for five years and reduces your score in the short term. Pause applications while your file is being repaired.
6. Pay every current bill on time — 24 months of clean repayment history information (CCR data) steadily improves your score as positive data accumulates.
7. Reduce credit card utilisation — aim for below 30% of your available limit across all cards combined.
8. Work with a knowledgeable broker — find ASIC-licensed mortgage brokers at asic.gov.au. A broker who understands credit files and lender credit policies is essential when your file is complex.

If debt hardship is a contributing factor, the National Debt Helpline (1800 007 007) offers free financial counselling and can help you sort out what's a credit file issue versus what's a cash-flow issue.

Frequently Asked Questions

What is the minimum credit score for a home loan in Australia? There is no universal minimum, but as a 2026 guide: the big four banks (CBA, ANZ, Westpac, NAB) generally require an Equifax score of 680 or above with no active defaults. Tier-two banks consider 650–680. Non-conforming lenders accept from around 500 but at rates 2–4% higher. An active default often blocks mainstream approval entirely regardless of score, under lenders' automatic-decline rules.

Can I get a home loan with a 600 Equifax credit score? Possibly — some tier-two banks and credit unions consider scores in the 580–650 range with a strong deposit and stable income. But the specific entries on your file matter more than the number. A default causing the low score can be disputed and removed in 30–90 days under the Privacy Act 1988 if it was listed without the required Section 21D notice — typically moving the score above the mainstream approval threshold.

Does a default automatically stop me getting a home loan in Australia? Not automatically — non-conforming lenders will still consider applications with active defaults. But all major banks apply automatic-decline rules for any default regardless of score. Under the Privacy Act 1988, a default listed without proper procedural notice can be professionally challenged. Australian Credit Solutions achieves a 98% success rate on accepted cases, and many clients move from non-conforming eligibility to mainstream approval within 30–90 days of removal.

Does paying off a default remove it from my credit file? No. Paying a default updates the status from "unpaid" to "paid", which some lenders view more favourably, but the entry stays on your file for the full five-year retention period under the Privacy Act 1988. The only way to have it removed before expiry is a successful dispute on procedural or factual grounds. See our full guide on whether paying a default removes it.

Can I get a home loan after a default is removed from my credit file? Yes — in most cases you can apply to mainstream lenders immediately. Once Australian Credit Solutions successfully disputes and removes a default, the credit reporting body updates your file within 5 business days under the Privacy Act 1988. Many clients move from non-conforming eligibility to mainstream bank approval within weeks of removal. Our guide on bad credit home loans in Australia covers what lenders look for post-removal.

How long does it take to improve your credit score enough for a home loan? If your score is low because of an unlawfully listed default, Australian Credit Solutions can typically have it removed in 30–90 days — often lifting the score into the approval band in a single step. Rebuilding through consistent on-time payments and no new applications takes 12–24 months for meaningful improvement. Credit repair is almost always the faster path when specific entries can be challenged.

What Equifax score do I need for the best home loan interest rate? To access the best available rates from the major banks, you generally want an Equifax score in the Very Good band (735–852) or Excellent (853+). The Good band (661–734) qualifies you for standard mainstream rates at most lenders. Below 660, a rate premium applies — and below 550, you're in non-conforming territory where rates can be 2–4% higher. MoneySmart (moneysmart.gov.au) has a home loan guide that explains how lenders structure pricing by risk tier.

How do I get my free credit report before applying for a home loan in Australia? Under the Privacy Act 1988, you're entitled to a free credit report from each of Australia's three bureaus — Equifax (equifax.com.au), Experian (experian.com.au) and Illion (creditreport.com.au) — once per year, or more often if a credit request has been declined. The OAIC (oaic.gov.au) publishes guidance on your credit-reporting rights. Getting all three reports is important before a home loan application — lenders may check any bureau, and entries don't always match across bureaus.

A free assessment from ACS tells you whether the entries holding your score below the home loan threshold can be challenged — and realistically, how quickly. For many clients, the path from rejection to mainstream approval is shorter than a mortgage broker estimated.
