Credit Scores and Home Loans: What Lenders Actually Look At
Your credit score is one of the first things a lender checks when you apply for a home loan — but it is rarely the whole story. Australian lenders look at the score together with the detail behind it: your repayment history, your existing debts, and how often you have applied for credit lately. Understanding how the system actually works helps you avoid the quiet missteps that weaken applications, and it costs nothing to check where you stand.
What a credit score actually is
A credit score is a number that summarises the information sitting on your credit file at a point in time. It is calculated by a credit reporting body — not by the lender — and it is designed to estimate how likely you are to miss repayments. Australia has three main credit reporting bodies: Equifax, Experian and illion. Each holds its own file on you, uses its own scale, and calculates its own score, so your number will differ between them. That is completely normal.
Each bureau groups scores into descriptive bands, typically running from below average through average, good and very good up to excellent. The exact numbers behind each band differ by bureau and are adjusted over time, so it pays to focus on which band you sit in and which direction you are trending, rather than obsessing over a single figure.
Comprehensive credit reporting changed the game
For a long time, Australian credit files mostly recorded negatives — defaults, bankruptcies and credit enquiries. Comprehensive credit reporting (CCR) changed that. Lenders now report positive data as well: the credit accounts you hold, your credit limits, and up to two years of month-by-month repayment history on loans and credit cards.
This cuts both ways. If you pay everything on time, every month, your file now proves it — a genuine advantage when a lender reads your history. If you routinely pay late, even by a couple of weeks, those late markers sit on your file for up to two years where every future lender can see them. A single missed month rarely sinks an application on its own, but a pattern of late payments in the months before you apply is one of the most common reasons a home loan gets a harder look.
What actually moves your score
Scoring models are proprietary, but the ingredients are well understood:
- Repayment history — paying loans, credit cards and (where reported) telco and utility accounts on time is the single biggest positive you control.
- Defaults, judgments and bankruptcies — serious negative events stay on file for years and outweigh almost everything else while they are listed.
- Credit enquiries — every credit application is recorded. Several applications in a short window can read as financial stress, even if you were only rate-shopping.
- Credit limits and account mix — high card limits and lots of small credit accounts, including buy now pay later where reported, all appear on your file.
- Age of your file — a longer, stable history generally helps.
Just as important is what does not directly affect your score: your income, your savings balance, and checking your own credit report. Self-checks are recorded as soft enquiries and are invisible to lenders.
How lenders really use your score
A common misconception is that banks approve everyone above a magic number and decline everyone below it. In practice, most lenders run their own internal scorecards, and your bureau score is only one input alongside your income, expenses, deposit and loan-to-value ratio (LVR). Credit assessors also read the file itself. An applicant with a modest score and a clean, explainable history can be a stronger case than someone with a higher score masking a recent unpaid default.
Lenders also apply their own credit policy on top. Some will not touch a file with any default; others will consider paid defaults with a reasonable explanation. Under the National Consumer Credit Protection Act (NCCP), every lender must verify your financial position and be satisfied the loan is not unsuitable — so the score is a filter, never the full assessment. This is where a broker earns their keep: matching your file to a lender whose credit policy actually fits it, which is a big part of [improving your approval chances](/articles/credit-and-approval/improve-approval-chances) before you apply for a [home loan](/loans/home-loans).

Checking your own file for free
You are legally entitled to a free copy of your credit report from each of the three bureaus once every three months, and additionally within 90 days of being declined for credit. Order all three, because they often hold different information — a default might appear with one bureau and not another. Each bureau's website has a free report request process; you will need identification documents to verify who you are.
Do this three to six months before you plan to apply. That gives you time to fix errors, let recent enquiries age, and build a run of clean repayment months — all far easier before an application than during one.
Fixing errors on your credit report
Credit files contain mistakes more often than people expect: paid defaults never updated, the same debt listed twice, accounts that belong to someone with a similar name, or enquiries you never made (a possible sign of identity theft). Corrections are free and you never need to pay a credit repair company for something you can do yourself.
- Start with the credit provider that listed the item and ask them to correct it with the bureau.
- If that stalls, lodge a correction request directly with the credit reporting body — they must investigate.
- If you are still not satisfied, escalate to the Australian Financial Complaints Authority (AFCA) at no cost.
Legitimate negative information cannot be removed early, no matter what a credit repair advertisement promises. But genuine errors come off, and removing one wrongly-listed default can change which lenders are open to you.
Score in context: it is one lever, not the only one
Even with a strong file, your borrowing power still comes down to income, commitments and deposit. Before you fixate on the score, run your numbers through a [borrowing capacity calculator](/calculators/borrowing-capacity) and make sure the loan size you want is realistic. A tidy credit file plus sensible spending in the months before applying, plus the right lender for your situation, is what actually gets approvals done — and you can see what paperwork you will need in our guide to [documents needed for a home loan](/articles/credit-and-approval/documents-needed-home-loan).

Frequently asked questions
What credit score do I need for a home loan in Australia?
There is no single cutoff. Each bureau uses its own scale and bands, and each lender applies its own scorecard and credit policy on top. A score in the good-to-excellent bands makes life easier, but lenders assess the whole file — repayment history, debts, enquiries, income and deposit — not just the number.
Does checking my own credit score lower it?
No. Checking your own report or score is recorded as a soft enquiry, which lenders cannot see and which does not affect your score. Only actual credit applications create the hard enquiries that appear on your file.
Why is my score different between Equifax, Experian and illion?
Each bureau holds its own data, uses its own scoring scale, and may receive different information from different credit providers. It is normal for your three scores to differ. Lenders typically pull from one or two bureaus, so it is worth checking all three before applying.
How long do defaults and missed payments stay on my credit file?
Repayment history information, including late payments, generally stays on file for two years. Defaults typically remain for five years even after you pay them, though a paid default reads better than an unpaid one. More serious events like bankruptcy are listed for longer.
Can I get a home loan with a default on my file?
Sometimes, yes. Policies vary widely — some lenders decline any default, others consider paid defaults with a reasonable explanation, and specialist lenders exist for harder cases, usually at higher rates. The right lender match matters far more than reapplying repeatedly, which only adds enquiries.
Do buy now pay later accounts affect my credit score?
Increasingly, yes. Some buy now pay later providers report accounts and repayment behaviour to credit bureaus, and lenders can see the spending in your bank statements regardless. Heavy reliance on these services in the months before applying can hurt an application even where the score is untouched.
