Credit and Home Loans Australia — What You Need to Know

Your credit history is one of the most important factors lenders consider when assessing a home loan application. In Australia, the credit reporting system captures both positive and negative payment behaviour — and a strong credit profile can improve both your approval chances and the interest rate you are offered.

How the Australian Credit Reporting System Works

Credit information is collected and held by three Credit Reporting Bureaus (CRBs):

Each bureau operates independently. Lenders report to one or more bureaus and check one or more when assessing applications — your file at each bureau may be slightly different.

Comprehensive Credit Reporting (CCR), mandatory for large banks since 2019, means lenders must now share positive repayment data, not just negative events. This is significant: a history of making all repayments on time across your credit cards, personal loans, and utilities now actively supports your credit file, rather than only defaults and missed payments appearing.

What Appears on Your Credit File

Your credit file contains:

• Personal information: name, date of birth, address history, employer
• Credit enquiries: every time you apply for credit (card, loan, mortgage), an enquiry is recorded. Multiple enquiries in a short period signal financial stress to lenders.
• Credit accounts: current and historical credit products (cards, loans, buy now pay later), limits, and open/close dates
• Repayment history: under CCR, whether each payment was made on time for the past 24 months
• Defaults: overdue accounts over $150 that went unpaid for 60+ days and were listed by the creditor
• Court judgements and bankruptcy: serious legal events that remain on file for 5–7 years

Credit Score Ranges and What They Mean for Mortgages

Different credit bureaus use different scoring scales, but as a guide (Equifax 0–1,200 scale):

Most major banks look for a score above 600 on the Equifax scale. Specialist (non-conforming) lenders will consider applicants with lower scores but charge higher interest rates — typically 1–4% above mainstream rates.

The Most Damaging Credit Events for a Mortgage Application

Default: An overdue debt over $150 listed by a creditor after 60 days. Defaults remain on your file for five years. Even paid defaults remain listed (as “settled”) for five years from the original listing date. A recent default (within two years) will disqualify you from most mainstream lenders.

Credit enquiries: Each credit application creates a hard enquiry. Multiple enquiries — particularly several in a short period — signal to lenders that you have been seeking credit aggressively or been declined elsewhere. Avoid applying for new credit cards or personal loans in the 6–12 months before a mortgage application.

Late payments: Under CCR, even payments that are 14+ days late are recorded. A pattern of late payments, even small ones, can lower your score materially.

Bankruptcy: Listed for two years after discharge (or five years from the date of bankruptcy, whichever is longer). Most mainstream lenders will not approve a mortgage until at least two years after discharge, and often longer.

How to Improve Your Credit Before Applying

Check your file first: Get your free credit report from Equifax, Experian, and illion. Check for errors — incorrect defaults, outdated information, or accounts that are not yours. Errors can be disputed with the bureau directly.

Pay all existing obligations on time: Under CCR, your last 24 months of repayment history matters. Set up direct debits to ensure minimum payments are never missed.

Reduce credit card limits: Unused credit card limits count against your borrowing capacity. Closing or reducing limits 6–12 months before applying improves both your credit profile and your assessed borrowing capacity.

Avoid new credit applications: Every hard enquiry is visible. If you are planning to apply for a mortgage in the next 12 months, avoid applying for new credit cards, personal loans, or buy now pay later accounts.

Frequently Asked Questions

What credit score do I need for a home loan in Australia? Most mainstream lenders require approximately 600+ on the Equifax scale, though each lender has its own internal thresholds. Credit score is one input — income, deposit, and employment stability also matter significantly.

How long do defaults stay on my credit file in Australia? Defaults remain on your credit file for five years from the date they were listed — regardless of whether you pay them. A “paid default” is listed as settled but remains visible for the full five years.

Can I get a home loan with bad credit in Australia? Yes, through non-conforming or specialist lenders who accept borrowers with adverse credit history. These loans carry higher interest rates (typically 1–4% above standard rates) and stricter LVR requirements. As adverse credit events age and your history improves, options expand.

Does checking my own credit score affect my rating? No. Checking your own credit file (a “soft enquiry”) does not affect your credit score. Only “hard enquiries” — applications for credit products — impact your score.
