Credit Cards in Australia:
What Every Student Should Know

Your "credit score" might not be what you think

This is something a lot of people get tripped up on. When your bank shows you a credit score inside their app — like CommBank's score visible in NetBank — that's not necessarily your official credit score. These are often internal or partner-based indicators sometimes called behavioural scores, which estimate your creditworthiness based on your transaction history and account behaviour. They're a useful rough guide, but they're not the figure a lender pulls when you apply for a loan.

Your actual credit score is calculated by credit reporting agencies like Equifax, Experian, or illion, and it's based on a broader picture of your financial behaviour. The main factors include:

• Repayment history (whether you pay on time)
• How often you apply for credit
• Your credit limits and how much of them you're using
• Any defaults or late payments
• The types of credit you hold

How a credit card actually works

A credit card lets you borrow money from a bank up to a set limit, spend it now, and repay it later. Unlike a debit card, you're not spending your own money: you're spending borrowed money that you'll need to pay back.

Cash advances: Using your credit card to withdraw cash from an ATM, transfer money to another account, or purchase items like gift cards or gambling is treated as a cash advance.

Types of Credit Cards in Australia

Now that you understand how credit cards work, here's a rundown of the main types available in Australia and what they're best suited for. The general appeal of cards here is the rewards and introductory offers, but keep in mind that if you're not a consistent big spender, a card might only make sense to hold for the first year to take advantage of a sign-up deal before the second annual fee kicks in.

When a credit card actually makes sense

A credit card can genuinely work in your favour when used with intention. Taking advantage of a sign-up cashback offer, earning points on spending you were already planning to make, or using it as a disciplined way to pay for regular expenses and build repayment habits are all reasonable reasons to have one.

Where it gets problematic is when a card starts filling gaps in your budget. Using credit to fund a lifestyle you can't really afford, relying on minimum repayments to get by, or using a new card to cover spending from the last one are cycles that are genuinely hard to break out of once you're in them.

Real risks for students worth keeping in mind

• 1
  Overspending. The minimum credit limit you get approved for is often higher than what you'd earn or usually spend in a normal month, which makes it easy to tap and forget about it until the statement arrives.
• 2
  Interest snowball. Small unpaid balances grow quickly at 20%+ p.a. interest rates.
• 3
  Debt cycles. Using credit to pay off previous spending is a warning sign, not a solution.

So, should you get one?

For most students, it's not a simple yes or no. A credit card can be a useful tool if you can consistently pay the full balance each month, you understand how interest and fees work, and you want to start building responsible financial habits.

It's probably worth waiting if your income is inconsistent, you tend to overspend, or you're not in the habit of tracking your expenses.

Credit cards aren't inherently good or bad. They're just tools, and their impact depends almost entirely on how you use them. In Australia, you genuinely don't need one to build a strong financial future. But if you do choose to get one, the responsibility for how it goes sits with you.
