Understanding Credit Reporting Agencies & How They Affect Your Credit Score in Australia
As a mortgage broker, one of the most important factors we consider when helping you secure a loan is your
credit score. But how is this score determined, and why is it so important? The answer lies in
credit reporting agencies—the organisations that collect and manage your credit history in Australia.
What Are Credit Reporting Agencies?
Credit reporting agencies (also known as credit bureaus) are companies that collect and maintain information about your credit activity. They track how well you manage your debts, including loans, credit cards, and other forms of credit. In Australia, there are three main credit reporting agencies:
- Equifax (formerly Veda)
- Experian
- illion (formerly Dun & Bradstreet)
These agencies receive data from lenders, banks, and other financial institutions about your borrowing and repayment behaviour. This data includes information such as the amounts you owe, whether you pay on time, and any defaults or missed payments.
How Do Credit Reporting Agencies Impact Your Mortgage Application?
Your credit score—which is determined by the data collected by credit reporting agencies—plays a crucial role in your ability to qualify for a mortgage. Lenders use this score to assess your financial responsibility and the level of risk they take when lending to you. A higher score typically results in better loan terms, such as lower interest rates.
When you apply for a mortgage, lenders will request your credit report from one or more of the major credit bureaus. They will review various factors, including:
Credit Score: Your overall score (typically ranging from 0 to 1,200 in Australia) reflects your creditworthiness.
Credit History: Lenders examine the length of your credit accounts, payment history, and how much debt you currently have.
Credit Utilisation: This is the percentage of your available credit that you are using.
How to Protect Your Credit Score
Your credit score is vital not only for securing a mortgage but also for your overall financial health. Here are some important steps you can take to protect and improve your credit score in Australia:
1. Pay Your Bills on Time
Your payment history makes up a significant portion of your credit score. Late payments can have a negative impact, so it’s crucial to pay your bills, loans, and credit cards on time. Set up automatic payments or reminders if necessary.
2. Check Your Credit Report Regularly
In Australia, you are entitled to request a free copy of your credit report once a year from each of the major credit reporting agencies. Regularly reviewing your credit report helps you spot any errors or inaccuracies that could affect your score. You can access these reports via the credit bureaus’ websites or through services like AnnualCreditReport.com.au.
3. Reduce Your Credit Card Balances
Credit utilisation—the amount of credit you're using compared to your credit limit—affects your score. Aim to keep your credit utilisation below 30%. For example, if you have a credit card with a $10,000 limit, try not to carry more than $3,000 in debt.
4. Be Cautious When Opening New Credit Accounts
Every time you apply for credit, a "hard inquiry" is made on your credit report, which can temporarily lower your score. Avoid applying for too many credit cards or loans in a short period, as this can signal financial stress to lenders.
5. Keep Old Accounts Open
The length of your credit history also influences your credit score. If you have older credit accounts in good standing, it’s often beneficial to keep them open, even if you don’t use them regularly. Closing accounts may shorten your credit history and reduce your available credit.
6. Dispute Errors or Signs of Fraud
If you notice any incorrect information on your credit report, such as a late payment that was actually paid on time or accounts you don’t recognise, you can dispute these errors directly with the credit bureau. Fraudulent activity, like identity theft, can also harm your credit score, so it’s important to report it quickly.
7. Use Credit Responsibly
Using credit responsibly is essential to maintaining a good credit score. This includes paying off balances in full each month and borrowing only what you can afford to repay. Try to avoid maxing out your credit cards and stay within your credit limits.
What Happens if You Have a Low Credit Score?
If your credit score is lower than desired, you may still be able to qualify for a mortgage, but the terms may be less favourable. This could include higher interest rates or a lower loan amount. In some cases, if your score is too low, securing a mortgage may be difficult. This is why it’s essential to keep track of your credit score and take steps to improve it when necessary.
