Getting rejected for credit because of your credit score leaves you wondering what went wrong. The rejection letter mentions your credit score, but it doesn’t explain which factors pushed your rating down or what you can do about it.
Your Australian credit score is calculated using several factors, but three of the most important are credit utilisation, payment history and account age. Understanding how these work helps you see what lenders actually check when they assess your application.

What is credit utilisation?
Credit utilisation is the percentage of your available credit that you use each month. If you have a credit card with a $5,000 limit and you owe $1,500, your credit utilisation is 30%.
Credit reporting bodies in Australia track your credit utilisation by looking at the balance you owe compared to your credit limit at the end of each month. This information comes from your credit provider and appears on your credit file.
How credit utilisation affects your score
Lower credit utilisation generally means a higher credit score. Most credit scoring models prefer to see utilisation below 30%, with some favouring even lower levels around 10-20%.
High credit utilisation suggests you rely heavily on credit to manage your finances. Lenders see this as a potential sign of financial stress, which increases their lending risk.
What counts towards your utilisation
Credit utilisation includes:
- Credit card balances
- Store card balances
- Personal credit lines
- Overdraft facilities
It does not include:
- Home loan balances
- Car loan balances
- Personal loan balances (fixed amount loans)
- Buy now, pay later arrangements (unless they report to credit agencies)
Understanding payment history
Payment history records whether you make your credit payments on time, late, or miss them entirely. This factor carries significant weight in Australian credit scoring models.
What appears in your payment history
Your credit file shows:
- On-time payments (recorded as positive credit information)
- Late payments (recorded when you’re 14 days or more overdue)
- Missed payments
- Defaults (when you’re 60+ days overdue on amounts over $150)
- Court judgements for unpaid debts
How late payments affect your score
Recent late payments have more impact than older ones. A missed payment from last month affects your score more than one from three years ago. Multiple recent late payments create a pattern that concerns lenders.
The severity of the late payment also matters. A 30-day late payment has less impact than a 90-day late payment, which has less impact than a default.
Positive payment history benefits
Consistent on-time payments over several years demonstrate reliable payment behaviour. This positive history can offset occasional late payments and helps build a stronger credit profile over time.
Account age and credit history length
Account age refers to how long you’ve maintained credit accounts. Credit scoring models look at both the age of your oldest account and the average age of all your accounts.
Why account age matters
Longer credit history provides more data points for lenders to assess your payment behaviour. Someone with 10 years of credit history offers more predictable risk assessment than someone with six months.
Account age also demonstrates financial stability. Maintaining credit accounts for several years suggests you can manage ongoing credit relationships responsibly.
Building account age strategically
Keeping older credit accounts open, even if you don’t use them regularly, helps maintain a longer average account age. Closing your oldest credit card can reduce your average account age and potentially lower your credit score.
However, accounts with annual fees or accounts you cannot manage responsibly should be closed regardless of their age. The cost and risk outweigh the credit score benefit.
How these factors work together
Credit utilisation, payment history and account age interact to create your overall credit profile. A person with low utilisation, perfect payment history and long account age will typically have a high credit score.
Common scenarios and their impact
Scenario 1: High utilisation, good payment history, long account age
This person pays on time but uses most of their available credit. Their score may be moderate because high utilisation suggests financial stress, despite their reliable payment behaviour.
Scenario 2: Low utilisation, recent late payments, medium account age
This person doesn’t rely heavily on credit but has missed payments recently. The late payments will significantly impact their score, even with low utilisation.
Scenario 3: Medium utilisation, perfect payment history, short account age
This person manages credit well but hasn’t had credit accounts for long. Their score may be good but not excellent due to limited credit history.
What to check on your credit file
Reviewing your credit file helps you understand how these factors currently affect your credit score:
- Check utilisation calculations: Verify that reported balances and credit limits are accurate
- Review payment history: Look for incorrectly reported late payments or missed payments you believe you made on time
- Confirm account details: Check that account opening dates, closure dates and account types are correct
- Identify errors: Look for accounts you don’t recognise or information that belongs to someone else
- Review defaults carefully: Check that any defaults were listed correctly and follow proper procedures

Improving your credit utilisation
Pay down existing balances
Reducing what you owe immediately improves your utilisation ratio. Focus on accounts with the highest utilisation first, as these have the most impact on your overall ratio.
Request credit limit increases
Increasing your available credit without increasing your balances lowers your utilisation ratio. However, be cautious about using the additional credit, as this defeats the purpose.
Make multiple payments per month
Credit utilisation is typically calculated based on your statement balance. Making payments before your statement closes can reduce the balance that gets reported.
Consider balance transfers carefully
Balance transfers can help consolidate debt and potentially reduce interest costs, but they don’t improve your overall utilisation unless you also increase your total available credit.
Building positive payment history
Set up automatic payments
Automatic minimum payments ensure you never miss a due date, even if you choose to pay more manually. This creates a safety net for your payment history.
Pay early rather than on time
Paying a few days before the due date provides a buffer for processing delays and demonstrates proactive payment management.
Keep accounts active with small purchases
Using older credit accounts occasionally for small purchases keeps them active and continues building positive payment history on those accounts.
Monitor payment posting
Ensure your payments post correctly and on time. Payment processing delays can sometimes result in incorrectly recorded late payments.
Managing account age effectively
Keep old accounts open
Unless an account has high fees or you cannot control spending on it, keep older accounts open to maintain your credit history length.
Use old accounts periodically
Make small purchases on older accounts occasionally to keep them active. Some credit providers close accounts after extended periods of inactivity.
Be strategic about new accounts
Each new account reduces your average account age. Only open new credit accounts when necessary and beneficial to your overall financial situation.
Consider product switches instead of closures
If you want to change credit card features, ask about product switches that maintain your account opening date rather than closing and reopening accounts.
When defaults complicate the picture
Defaults significantly impact your credit score and override many positive factors. A default stays on your credit file for five years and affects your ability to get credit during that time.
However, not all defaults are listed correctly. Some may have procedural errors, incorrect amounts, wrong dates or other issues that make them worth challenging.
If you have defaults affecting your credit score, it may be worth reviewing whether they were listed according to proper procedures. Learn more about what dealers and finance companies actually check when assessing applications with defaults.
Different credit scores measure different things
Australia has several credit scoring systems, and each weighs these factors differently. Understanding VedaScore vs Equifax Score vs Experian Score helps you see why your scores might vary between credit reporting bodies.
Some lenders use their own internal scoring models that may weight certain factors more heavily than the standard credit bureau scores.
Industry-specific considerations
Rental applications
Property managers increasingly check credit files when assessing rental applications. They focus particularly on payment history and any defaults, as these indicate your likely behaviour with rent payments.
Specialist lenders
Some lenders specialise in applications from people with lower credit scores or defaults. These lenders may place different emphasis on the three factors, sometimes focusing more on current income and circumstances than historical credit behaviour.
Credit file monitoring and maintenance
Regular reviews
Check your credit file at least annually to ensure the information remains accurate. Credit reporting errors can negatively impact your utilisation calculations, payment history or account age records.
Dispute incorrect information
If you find errors affecting these three factors, lodge disputes with the relevant credit reporting body. Incorrect information can artificially lower your credit score.
Keep records
Maintain records of your payments, account statements and correspondence with credit providers. This documentation helps if you need to dispute incorrect payment history information.

Frequently asked questions
What is a good credit utilisation ratio in Australia?
Most credit scoring models prefer utilisation below 30%, with many favouring levels around 10-20%. However, having some utilisation (rather than zero) can be beneficial as it shows you actively use credit responsibly. The key is keeping balances well below your limits while making regular payments.
How long does it take for improved payment history to affect my credit score?
Payment history updates typically appear on your credit file within 30-60 days after the payment due date. Positive changes may start affecting your credit score within 1-3 months, but building a strong pattern of on-time payments takes 6-12 months to significantly improve your score.
Does closing old credit cards hurt my credit score?
Closing old credit cards can hurt your credit score in two ways: it reduces your available credit (potentially increasing utilisation) and decreases your average account age. However, if the card has high annual fees or you struggle with spending control, closing it may be the right financial decision despite the temporary score impact.
Can I have good credit with a short credit history?
Yes, but it’s more challenging. You can build good credit with a short history by maintaining low utilisation, making all payments on time, and keeping accounts open. However, your score may be limited compared to someone with identical behaviour over a longer period.
How do multiple credit cards affect these three factors?
Multiple credit cards can help by increasing your total available credit (lowering utilisation) and providing more opportunities to build positive payment history. However, they also create more accounts to manage and more potential for mistakes. The key is only maintaining cards you can manage responsibly.
What happens to these factors if I have a default on my credit file?
A default significantly impacts your credit score regardless of your utilisation, payment history on other accounts, or account age. The default shows a serious payment failure and remains on your file for five years. However, continuing good behaviour on other accounts during this time helps your score recover faster once the default falls off.
Do buy now, pay later services affect credit utilisation?
Most buy now, pay later services don’t report to credit bureaus for regular usage, so they don’t affect your credit utilisation calculations. However, if you default on these services, they may report the default, which significantly impacts your credit score through the payment history factor.
Can I improve my credit score quickly by paying off all my credit cards?
Paying off credit cards improves your utilisation ratio, which can boost your score within 1-2 months. However, closing the accounts may hurt your score by reducing available credit and average account age. The best approach is usually to pay down balances while keeping accounts open with low utilisation.
