Key takeaways
- Lenders assess your whole credit file, not just the number — score is one input among income, deposit and expenses.
- Payment history is the single biggest driver; on-time repayments now help you under Comprehensive Credit Reporting.
- Multiple loan applications in a short window leave hard enquiries that can weigh on your file.
- A lower score narrows your lender options but rarely rules you out on its own.
People treat their credit score like an exam result — a single number that decides everything. Lenders don’t see it that way. To them it’s a summary of a much richer file: how you’ve handled credit, how recently you’ve applied for it, and whether anything has gone wrong. Understanding what’s in that file is how you stop guessing and start improving it.
What your score is built from
- Payment history. Do you pay on time? This is the heaviest factor by far.
- Credit enquiries. How often you’ve applied for credit, and how recently.
- Credit used vs available. High card balances and large limits both count against you.
- Defaults and adverse events. Missed payments over a threshold, defaults, or court judgments.
- Length and mix. A longer, well-managed history of different credit types helps.
Comprehensive Credit Reporting changed the game
Australia now runs Comprehensive Credit Reporting, which means lenders see the positives too — not just the black marks. Every on-time repayment is now working for your file, not simply avoiding damage. The flip side: late payments show up in more detail, so consistency matters more than ever.
The most common self-inflicted wound: applying to several lenders “to compare,” each leaving a hard enquiry within weeks. Compare the market first, then apply once, to the right lender. That’s a core reason to work with a broker rather than shopping bank to bank.
Defaults and enquiries, in plain terms
A hard enquiry is recorded whenever you formally apply for credit; a few over years is normal, several in a month is a red flag. A default is generally listed when a payment over a set amount is overdue beyond a set period and follows the required notices — it can stay on your file for years, but it’s not automatically fatal to a home loan. Lenders will often accept an explained, paid default far more readily than a pattern of recent missed payments. If your file has a blemish, the right lender and the right framing matter enormously.
Improving your file before you apply
Give yourself a few months: check your file for errors and dispute them, pay everything on time, bring card balances and limits down, and avoid new applications. Then have your borrowing power and pre-approval handled by someone who knows which lenders suit your profile — because with credit, where you apply is as important as when.

What credit score do I need for a home loan?
There’s no single cut-off. Lenders don’t approve or decline on score alone — they read your full credit file alongside income, deposit and expenses. A higher score widens your choice of lenders and can unlock sharper rates, while a lower score narrows the options but rarely rules you out on its own. What matters most is the story your file tells: steady repayments, few recent enquiries, no unexplained defaults.
Does checking my own credit score lower it?
No. Checking your own credit file is a “soft” enquiry and has no effect on your score — you can and should do it before applying. What lenders notice are “hard” enquiries: formal credit applications. Several of those in a short window can weigh on your file, which is exactly why applying to many lenders at once is a mistake.
How can I improve my credit score before applying?
Pay every bill and repayment on time (payment history is the biggest factor), reduce credit-card limits and balances, avoid new applications in the months before you apply, and correct any errors on your file. Under Comprehensive Credit Reporting, consistent on-time payments now actively help you, not just protect you. Small, steady habits over a few months move the needle more than any single action.
