How Young Adults Can Build Credit in Australia: Complete Guide

Building your financial future starts here - Updated September 2025

Starting your financial journey as a young adult in Australia can feel overwhelming. You've probably heard that you need good credit to buy a home, get a car loan, or even secure certain jobs – but where do you actually begin when you have no credit history at all?

Here's the reality: most young Aussies leave school or university with zero credit history, which can be just as challenging as having bad credit. Lenders don't know whether to trust you because there's simply no track record to assess. But here's the good news – building credit from scratch is entirely achievable with the right strategy.

I've helped countless young adults across Australia establish solid credit foundations that set them up for financial success. Whether you're 18 and just starting out, or in your twenties trying to get your financial life sorted, this comprehensive guide will show you exactly how to build a strong credit score that opens doors to your financial goals.

Understanding Credit Scores in Australia: The Basics You Need to Know

Before jumping into strategies, let's get crystal clear on what we're actually building. Your credit score is essentially your financial reputation expressed as a number. In Australia, credit scores typically range from 0 to 1,200 (depending on the credit reporting agency), with higher scores indicating better creditworthiness.

The Three Credit Reporting Bodies in Australia:

Equifax: Uses a 0-1,200 scale
Experian: Uses a 0-1,000 scale
Illion: Uses a 0-1,000 scale

Your credit score is calculated based on several key factors:

Payment History (35% of your score) This is the big one. Every payment you make – or miss – on credit cards, loans, phone bills, and utilities can impact your score. Consistent on-time payments are the foundation of good credit.

Credit Utilisation (30% of your score) This measures how much credit you're using compared to your available limit. If you have a $2,000 credit card limit and consistently carry a $1,500 balance, that's 75% utilisation – way too high.

Length of Credit History (15% of your score) The longer you've had credit accounts open and active, the better. This is why starting early gives you a significant advantage.

Types of Credit (10% of your score) Having a mix of credit types – credit cards, personal loans, mobile phone contracts – shows lenders you can manage different kinds of credit responsibly.

New Credit Enquiries (10% of your score) Each time you apply for credit, it generates an enquiry on your report. Too many enquiries in a short period can hurt your score.

Why Building Credit Early Is Your Secret Weapon

Starting to build credit in your late teens or early twenties isn't just helpful – it's one of the smartest financial moves you can make. Here's why:

Compound Benefits Over Time Credit building is like investing – the earlier you start, the more time you have for your efforts to compound. A 20-year-old who starts building credit responsibly will have a significant advantage over someone who waits until their 30s.

Lower Interest Rates Save Thousands Good credit can save you enormous amounts of money over your lifetime. On a typical $400,000 home loan, the difference between excellent credit and poor credit could cost you $50,000+ in extra interest payments.

More Housing Options Many landlords run credit checks before approving rental applications. Good credit can mean the difference between getting that perfect apartment and having to settle for something less desirable.

Employment Opportunities Some employers, particularly in finance, government, and security sectors, conduct credit checks as part of their hiring process. Poor credit could limit your career options.

Financial Flexibility Good credit gives you options during emergencies. Whether it's an unexpected medical bill or sudden job loss, having access to credit can provide crucial breathing room.

The 11 Best Strategies for Young Adults to Build Credit

Now let's dive into the practical strategies that actually work for building credit from scratch:

1. Start with Your First Credit Card (But Choose Wisely)

Getting your first credit card is often the most practical way to start building credit. However, not all credit cards are suitable for beginners.

Best Options for First-Time Applicants:

Student credit cards (if you're studying)
Low-limit cards designed for new credit users
Cards from your existing bank (they already know your banking history)

How to Use Your First Card Successfully: Keep your balance below 30% of your credit limit – ideally under 10%. If you have a $1,000 limit, aim to use no more than $100-300 at any time. Pay off the full balance every month to avoid interest charges. Use the card for regular, budgetable expenses like groceries or petrol, not for splurges you can't afford.

Set up automatic payments for at least the minimum amount to ensure you never miss a payment. Even one missed payment can significantly damage your new credit profile.

2. Become an Authorised User on a Family Member's Account

This strategy allows you to benefit from someone else's good credit history while you're building your own. Here's how it works:

Ask a parent, guardian, or trusted family member with excellent credit to add you as an authorised user on one of their credit cards. Their positive payment history and low utilisation on that card will appear on your credit report, giving your score an immediate boost.

Important Considerations: Make sure the primary cardholder has excellent payment history and keeps their utilisation low. Any negative behaviour on their part will also affect your credit. Agree on spending limits and responsibility for payments upfront to avoid family conflicts.

This strategy works best when combined with other credit-building activities, as it provides a foundation while you establish your own credit accounts.

3. Make All Bill Payments on Time, Every Time

Your payment history is the most important factor in your credit score, and it's not just about credit cards and loans. In Australia, missed payments on utilities, phone bills, and even some subscription services can end up on your credit report.

Bills That Can Affect Your Credit:

Mobile phone contracts
Utility bills (electricity, gas, water)
Internet and cable bills
Buy-now-pay-later services (Afterpay, Zip, etc.)
Gym memberships and subscription services

Payment Success Strategies: Set up automatic payments where possible, especially for fixed amounts like phone bills. Use calendar reminders for variable bills like utilities. Keep a small buffer in your bank account to cover automatic payments, preventing overdrafts that could cause missed payments.

4. Consider a Small Personal Loan

Taking out a small personal loan that you can easily afford can help diversify your credit mix and demonstrate your ability to handle instalment debt.

How to Do This Safely: Only borrow what you can comfortably repay within 12-24 months. Use the loan for something practical like a laptop for work or study, not for discretionary spending. Make sure the monthly payment fits easily within your budget with room to spare.

Shop around for the best interest rates, but be mindful that each application creates a credit enquiry. Make your applications within a 14-day window so they're treated as a single enquiry for credit scoring purposes.

5. Monitor Your Credit Report Religiously

You can't improve what you don't measure. Regularly checking your credit report helps you track your progress and catch any errors that could be holding you back.

How to Monitor Effectively: Get your free annual credit report from all three major agencies: Equifax, Experian, and Illion. Use free credit monitoring services like Credit Savvy or GetCreditScore to track your score monthly.

Look for errors such as incorrect personal information, accounts that don't belong to you, or incorrect payment history. Dispute any errors immediately – the agencies are required to investigate within 30 days.

6. Keep Credit Enquiries to a Minimum

Every time you apply for credit, it generates a "hard enquiry" on your credit report. While one or two enquiries per year won't hurt much, multiple enquiries in a short period can significantly damage your score.

Smart Application Strategies: Research your options thoroughly before applying. Many lenders offer pre-qualification tools that don't affect your credit score. Space out credit applications by at least 3-6 months unless you're rate shopping for a specific loan type.

When shopping for a car loan or personal loan, make all your applications within a 14-day window so they count as a single enquiry.

7. Use a Secured Credit Card If Necessary

If you're having trouble getting approved for a regular credit card, a secured credit card can be an excellent starting point.

How Secured Cards Work: You put down a cash deposit (usually $200-$500) that serves as your credit limit. This reduces the risk for the lender, making approval much easier. Use the card for small, regular purchases and pay the balance in full each month.

After 6-12 months of responsible use, many lenders will convert your secured card to a regular credit card and refund your deposit. This strategy is particularly useful if you have no credit history or previous credit problems.

8. Keep Old Accounts Open

Once you've established credit accounts, resist the urge to close them unless absolutely necessary. The length of your credit history accounts for 15% of your score, and closing accounts shortens your average account age.

When to Keep Accounts Open: Keep your first credit card open indefinitely, even if you get better cards later. Use it occasionally for small purchases to keep it active. Only close accounts if they have high annual fees that you can't justify, or if having too many open accounts is causing you to overspend.

9. Consider a Co-Signer for Major Purchases

If you need a car loan or other major credit but don't qualify on your own, a co-signer with good credit can help. This is different from being an authorised user – you're the primary borrower, but the co-signer guarantees the debt.

Co-Signer Considerations: Choose your co-signer carefully – missed payments will hurt both of your credit scores. Have a clear agreement about payment responsibility and communication. Use this as a stepping stone to establish your own credit, not as a long-term solution.

10. Practice Excellent Financial Habits

Building credit isn't just about managing credit accounts – it's about developing overall financial responsibility.

Essential Habits: Create and stick to a budget that includes all your expenses and debt payments. Build an emergency fund, even if it's just $500 to start. This prevents you from relying on credit for unexpected expenses. Live below your means and avoid lifestyle inflation as your income increases.

Track your spending to ensure you're not gradually increasing your credit utilisation without realising it.

11. Educate Yourself Continuously

The credit landscape is constantly evolving, and staying informed helps you make better decisions.

Learning Resources: Follow ASIC's MoneySmart website for official Australian credit information. Read reputable financial publications and blogs. Consider taking a personal finance course online or through your local TAFE.

Understanding how credit works empowers you to make strategic decisions rather than just following generic advice.

Australian-Specific Credit Building Tips

Building credit in Australia has some unique aspects that differ from other countries:

Comprehensive Credit Reporting Australia uses comprehensive credit reporting, which means positive payment history is reported, not just negative events. This makes it easier to build a good score by demonstrating responsible behaviour.

Buy-Now-Pay-Later Impact Services like Afterpay and Zip are increasingly being reported to credit agencies. Use these services responsibly, as missed payments can now affect your credit score.

Utility Bills and Credit In Australia, utility companies can report missed payments to credit agencies. Set up direct debits for all your utility bills to avoid any issues.

Mobile Phone Contracts Phone contracts are a form of credit in Australia and can help build your credit history. Consider getting a post-paid plan rather than pre-paid if you can manage it responsibly.

Common Credit Building Mistakes to Avoid

Learning from others' mistakes can save you time and frustration:

Maxing Out Credit Cards Using your full credit limit, even if you pay it off, can hurt your score due to high utilisation. Always keep balances well below your limits.

Applying for Too Much Credit Too Quickly Multiple credit applications in a short period can make you look desperate for credit and hurt your score.

Ignoring Small Bills A $50 late fee on your gym membership might seem insignificant, but if it goes to collections, it can seriously damage your credit.

Closing Your First Credit Card Your first card is often your oldest account. Closing it can shorten your credit history and hurt your score.

Not Monitoring Your Credit Errors on credit reports are common, and identity theft can happen to anyone. Regular monitoring helps you catch and address issues quickly.
