What Affects Your Credit Score in Australia? (2026)

Quick Answer: In Australia, your credit score is affected by: defaults (most damaging — drops score 100–200 points, stays 5 years), court judgements (similar impact), excessive hard enquiries (each application creates an enquiry that stays 5 years), repayment history under Comprehensive Credit Reporting (missed payments visible for 2 years rolling), serious credit infringements (7 years), and the type/age of credit accounts you hold. Income, savings, employment status, and assets do NOT appear on your credit file and do NOT directly affect your credit score.

One of the most misunderstood areas of personal finance in Australia. People assume things affect their credit score that don't — and miss the things that do enormous damage. Here's the complete, accurate picture.

What DOES Affect Your Credit Score in Australia

1. Defaults — The Biggest Single Factor

A default is a record of an overdue debt that a credit provider has decided to list on your file. Requirements under the Privacy Act 1988:

• The debt must be at least $150
• A Section 21D written notice must be sent giving you 30 days to respond
• The debt must be at least 60 days overdue

Impact: A single default typically drops an Equifax score by 100–200 points immediately. Multiple defaults can drop a score to Below Average (under 459) — the zone where almost all mainstream lending becomes impossible.

Duration: 5 years from date of listing.

Important: Defaults listed in breach of the credit reporting process — wrong address for the Section 21D notice, incorrect amount, listed during a genuine dispute — can be legally removed before the 5-year period ends.

2. Court Judgements

A court order in favour of a creditor that has been recorded on your credit file. Similar score impact to a large default.

Duration: 5 years from date of judgement.

3. Hard Enquiries

Every time you apply for credit — a loan, credit card, phone plan, rental property — the provider pulls your credit file. This creates a hard enquiry.

Duration: 5 years per enquiry.

4. Repayment History (RHI) — Comprehensive Credit Reporting

Since 2018, Australian credit files include Comprehensive Credit Reporting (CCR). This means every monthly repayment on every credit account is now recorded — not just defaults. Missed or late payments appear on your file as negative RHI markers. Consistent on-time payments appear as positive markers.

Duration: 2 years rolling — the most recent 24 months of payment behaviour is visible.

This is both a positive and negative change. If you've been paying on time, your score benefits. If you've been missing payments, every one is recorded.

5. Serious Credit Infringements

A more severe category than a standard default. A serious credit infringement is listed when a credit provider believes you've intentionally avoided paying a debt — for example, if you've moved without a forwarding address and the debt remains unpaid.

Duration: 7 years (the longest retention period of any standard credit file entry).

6. Bankruptcy and Part IX Debt Agreements

Bankruptcy appears on your credit file for 5 years from discharge (or 7 years from commencement, whichever is longer). Part IX debt agreements remain for 5 years from the end of the agreement.

7. Type and Age of Credit Accounts

Having a mix of credit types (mortgage, credit card, car loan) and a long history of responsible use is a positive signal. Closing old credit card accounts can actually reduce your score by shortening your effective credit history.

What Does NOT Affect Your Credit Score in Australia

This surprises many people:

*Missed rent that results in a formal debt listing by a collection agency CAN appear as a default.

Your income, job, savings account balance — none of these appear on your credit file. Lenders assess these separately when evaluating an application, but they are not part of your credit score calculation.

Does Buy Now Pay Later Affect Your Credit Score?

Yes — and this has changed significantly in recent years. Under ASIC regulatory changes and Comprehensive Credit Reporting:

• Missed BNPL payments can appear as negative RHI markers
• Some BNPL providers now conduct hard enquiries at application — check each provider's terms
• Defaults from BNPL accounts (Afterpay, Zip Pay, Humm, Laybuy) are listed the same as any other creditor default

A $200 Afterpay default has exactly the same credit file impact as a $200 bank default. The amount doesn't determine the severity of the listing — the listing itself is the problem.

Does Zip Money Affect Your Credit Score?

Zip Money (unlike Zip Pay) involves a formal credit check and creates a hard enquiry. Missed payments are also reported. Treat Zip Money like a credit product — because it is one.

Does Income Affect Your Credit Score?

No — your income does not appear on your credit file and does not affect your credit score. However, income is a separate assessment factor that lenders use for serviceability (can you afford the repayments?) alongside your credit score (are you likely to repay?). You can have a high income and a terrible credit score — or a modest income and an excellent one.

Does a Novated Lease Affect Your Credit Score?

Yes — in two ways. The application creates a hard enquiry. The approved lease may also appear as a liability that reduces borrowing capacity. See our dedicated guide: Does a novated lease affect your credit score →

The Fastest Way to Improve Your Credit Score

If your score is low because of negative entries — particularly defaults — the fastest path is removal, not waiting. Negative entries listed in breach of the Privacy Act 1988 can be removed in 30–90 days.

Case study — Carlos, Adelaide: Carlos, 40, a logistics coordinator from Prospect, had an Equifax score of 491 due to two small telco defaults — $290 Vodafone and $380 Optus. His home loan application had been declined twice. Both defaults had Section 21D notice irregularities. Both removed in 33 days. Score moved to 668. Home loan approved.

Frequently Asked Questions

What affects your credit score the most in Australia? Defaults have the most damaging single impact on an Australian credit score — a single default can reduce an Equifax score by 100–200 points and trigger automatic declines. Court judgements have similar impact. Excessive enquiries (5+) within 12 months are the second most impactful negative factor.

Does income affect credit score in Australia? No — income does not appear on your credit file and has no effect on your credit score. Lenders assess income separately for serviceability purposes, but it plays no role in the credit scoring calculation.

Does buy now pay later affect your credit score in Australia? Yes — BNPL products can affect your credit score through missed payment reporting under Comprehensive Credit Reporting, hard enquiries on application (for some providers), and default listings if accounts go unpaid. Treat BNPL accounts the same way you would any credit product.

Does paying rent affect your credit score in Australia? On-time rent payments do not appear on your credit file and don't directly improve your credit score (unlike some other countries where rent reporting is available). However, unpaid rent that is passed to a debt collector and listed as a default will negatively affect your score.

Does a hard enquiry affect your credit score? Yes — each hard enquiry creates a small reduction in your credit score (typically 5–15 points on Equifax). Multiple enquiries within a short period have a compounding effect and signal financial stress to lenders.
