How to Improve Your Credit Score in Australia: A Practical Guide (2026)

Australia has three main credit reporting bureaus: Equifax (formerly Veda), Experian, and Illion (formerly Dun & Bradstreet). Each lender reports to one or more bureaus - which means your score can vary between them. A lender assessing your application may check one, two, or all three, depending on their policy.

Australia moved to a Comprehensive Credit Reporting (CCR) system in 2018, which means positive credit information (on-time payments, credit limits, account age) is now included in credit reports alongside negative information (defaults, missed payments). This is a significant change that rewards good payment behaviour more than the previous system did.

You're legally entitled to a free copy of your credit report from each bureau annually - and several services offer ongoing free access:

• CreditSavvy (creditSavvy.com.au): Free Equifax score and report, updated monthly. No credit card required.
• GetCreditScore (getcreditscore.com.au): Free Equifax score and report. Part of the Equifax ecosystem.
• ClearScore (clearscore.com): Free Experian score and report, updated monthly.
• Illion's Credit Simple: Free Illion score.
• Annual free report directly from bureaus: Equifax (equifax.com.au), Experian (experian.com.au), and Illion (creditreference.com.au) must provide one free report per year per person. Download all three to check for discrepancies.
• What to look for: Check for errors (wrong addresses, accounts you don't recognise, incorrect defaults), ex-partner accounts, and fraudulent credit applications. Errors are more common than most people expect.

Under comprehensive credit reporting, these factors influence your score:

• Payment history (highest weight): On-time payments build your score; late payments and defaults damage it significantly. Even a single default can reduce your score by 100–200 points and remains on your report for 5 years.
• Credit enquiries: Every credit application generates a hard enquiry on your report. Multiple enquiries in a short period signal financial stress to lenders and reduce your score. Each enquiry stays on your report for 5 years.
• Credit utilisation: How much of your available credit you're using. Using more than 30% of your combined credit card limits regularly reduces your score. This is one of the fastest factors to change.
• Age of credit history: Older accounts with good payment history improve your score. Closing your oldest credit card removes its positive history.
• Types of credit: A mix of credit types (mortgage, credit card, personal loan) can be marginally positive - but don't open accounts you don't need just for this.

These actions have the most direct impact on your Australian credit score:

• Pay every bill on time, every time: Set up direct debits for minimum credit card repayments, utility bills, loan repayments, and any BNPL services. A single missed payment damages your score; consistent on-time payments rebuild it. This is the single most important factor.
• Reduce credit card utilisation: Pay down balances to under 30% of your combined credit limit. If your total credit limit is $10,000, keep the combined balance below $3,000.
• Don't apply for credit unnecessarily: Every application creates a hard enquiry. Before applying for a loan or mortgage, stop all other credit applications for at least 3–6 months.
• Dispute errors on your report: Contact the credit bureau directly with supporting documentation if you find an error. Bureaus are legally required to investigate and correct errors within 30 days. Fixing an incorrect default or enquiry can produce an immediate score improvement.
• Request removal of paid defaults: If you have a default that has since been paid, contact the lender and request they update the listing to 'paid default'. It remains on your report but is weighted less negatively.
• Don't close old accounts: Length of credit history matters. Keep your oldest credit card open and active (even with minimal usage) rather than closing it.

For people with no negative FREE entries, consistent good behaviour (on-time payments, low utilisation) can improve a score by 50–100 points within 6–12 months. For people with defaults or missed payments, improvement is slower - negative FREE entries remain for 5 years, but their impact reduces over time as positive history accumulates.

If you're planning a mortgage application, start working on your credit score at least 12 months before you plan to apply. Lenders also look at your bank account behaviour (regular savings, avoiding dishonour fees) alongside your formal credit score.
