Both cards tap the same way at checkout, but if a purchase goes wrong the differences matter. Here is how credit and debit cards compare on disputes, fraud and spending control.

Quick summary
- A credit card is generally safer for online shopping because fraudulent charges are the issuer’s money, and your cash stays untouched while a dispute is investigated.
- Chargeback is a voluntary scheme run by the major card networks, usually with time limits of 45 or 120 days from purchase, and rules vary by provider.
- Debit card fraud takes your own money straight away, and how much you recover depends on how quickly you report and on your bank’s terms.
- A separate low-balance debit card used only for online shopping can cap your potential losses if your card details are compromised.
- Australians lost almost $2.2 billion to scams in 2025, so checking statements and using multi-factor authentication matters as much as card choice.
Every online checkout asks the same question in a slightly different way: pay by credit card, debit card, or something else. The two cards look identical at the tap of a button, but if a purchase goes wrong they behave very differently. Scammers cost Australians almost $2.2 billion in 2025, according to the National Anti-Scam Centre, so it is worth knowing which card gives you better backup before your details end up in the wrong hands.
The short answer
For most online purchases, a credit card is the safer bet. When you pay with credit you are spending the issuer’s money, so a fraudulent charge does not touch your actual cash. The disputed amount sits on your credit account while the bank investigates, and you generally do not have to pay it off in the meantime. Moneysmart, the federal government’s financial guidance service, lists credit cards and PayPal as the more secure ways to pay online.
A debit card is not a bad option, though. Used deliberately, with a low balance and a dedicated account, it can cap how much you stand to lose. Neither card wins on every count; the right pick depends on whether you value dispute backup or a hard spending limit more. The table below shows where each is stronger.
| Credit card | Debit card | |
|---|---|---|
| Where the money comes from | The issuer’s funds, which you repay later | Your bank account, deducted straight away |
| If your details are stolen | Fraudulent charges sit on your account while investigated; your cash untouched | Money leaves your account immediately; refunds can take days or weeks |
| Dispute route | Chargeback through the card network plus your issuer’s process | Chargeback is usually still available, but you argue while your balance is down |
| Spending control | Risk of debt and interest if you do not pay in full | You can only spend what is in the account |
| Suits | Shoppers who clear their balance each month | Shoppers who want a hard limit on what can be lost |
How credit card dispute rights work
A credit card is borrowed money. Pay the full balance by the due date and you usually avoid interest; carry a balance and interest accrues on what is left. That is the running cost of the protection.
If goods never arrive or turn up nothing like described, start with the merchant. Make a genuine attempt to sort the problem out with the seller, following their complaints process if they have one. If that goes nowhere, ask your card issuer to reverse the charge. This process is known as a chargeback, and the major card networks, including Visa, Mastercard, Maestro and American Express, have all signed up to it.
Chargeback is a voluntary scheme, not a legal guarantee. Your bank asks for the transaction to be reversed and tries to recover the money from the company you paid, but the exact rules vary by card provider. Time limits usually run 45 or 120 days from the purchase, so check your card’s rules rather than assuming. Refunds can also take a while, because your bank has to get the money back from the merchant before it can pass it on to you.
Make a habit of checking your statement as soon as it lands, so you spot mistakes and charges you never authorised early. Paying on time every month also protects your credit history, which lenders look at when deciding whether to do business with you and at what rate.
If your issuer will not help and you think that is unfair, you can complain to the Australian Financial Complaints Authority, which offers free and independent dispute resolution.
What debit cards do and don’t protect
With a debit card the money is yours, and it leaves your account almost instantly. If a thief gets your details, they have direct access to your balance, and a bank investigation can take days or even weeks. While you wait, scheduled payments can bounce and late fees can pile up, all because of someone else’s crime. A compromised debit card can disrupt rent, groceries and other essentials until the money is returned.
How much stolen money comes back depends heavily on how quickly you report the problem. The contrast is sharpest in the United States, where federal law sets liability at nothing if you report before fraud occurs, a $50 cap if you report within two business days, a $500 cap up to 60 days, and no protection at all after that. Those exact figures do not automatically apply to Australian accounts; what you recover depends on your card network’s rules and your bank’s own terms. The broader lesson holds everywhere: report a lost, stolen or compromised card straight away.
Debit cards are not defenceless. Chargeback schemes generally cover debit cards on the major networks, including Visa debit, Mastercard debit, Maestro and prepaid cards, so you can still ask your bank to reverse an unauthorised transaction. The difference is that while you wait, your own money is out of your hands.
Getting money back through your bank
Whichever card you used, the path to a refund looks similar. Contact the trader first and follow their complaints procedure if they have one. Keep a record of what you bought, where and when you bought it, how much you paid, and what the seller said when you raised the problem. If you cannot reach them or they will not help, ask your card provider to step in.
A few things to know along the way:
- Chargeback time limits are usually 45 or 120 days from the purchase, so do not sit on a dispute.
- Purchases made through PayPal generally fall outside card chargeback schemes. PayPal runs its own in-house protection, which is not backed by law, and you have 180 days, about six months, from payment to open a dispute on its website.
- Overseas sellers can be harder to deal with. You may not have the same consumer rights as with an Australian seller, and it can be difficult to contact them for a repair, replacement or refund.
- Check whether your card provider or the overseas seller charges an international transaction fee before you buy.
Keep checking your statements while a dispute is in progress, and be suspicious of any seller pushing you to pay with gift cards or cryptocurrency.
Where buy now, pay later fits in
Buy now, pay later sits apart from both cards. You are entering a separate agreement with the provider, and if a purchase goes wrong you generally raise it with that provider first rather than with your bank. Our guide to how buy now, pay later actually works explains the arrangements in more detail.
There is one crossover worth knowing. If you pay your instalments from a credit or debit card, you may be able to start a chargeback on that card when something goes wrong with the underlying purchase. Your bank or card provider might not agree to it, so treat it as a possibility rather than a right. The same applies if you paid only part of the cost by card; outcomes vary, so ask. And because the deductions come out of a linked card automatically, keep an eye on that card’s statements too.
When a debit card is the better choice
For some shoppers a debit card is the sensible pick. It puts a hard limit on spending: you can only pay with money you actually have, so there is no debt, no interest and no bill at the end of the month that you did not plan for. If you have struggled to clear a credit card balance before, the protection a credit card offers is worth less than the interest it can cost you.
Moneysmart suggests one setup that gets the best of both worlds: a separate debit card used only for online shopping, kept at a low balance. You transfer money onto it when you are about to buy something and leave it nearly empty otherwise. If your card details are compromised after a shopping session, there is very little for a thief to take.
Handy tip
Consider a separate debit card used only for online shopping. Transfer money onto it just before you buy and keep the balance low the rest of the time, so a compromised card costs you almost nothing.
A debit card also suits anyone who shares shopping duties in a household and wants spending kept visible, or who simply prefers paying from money on hand.
Either way: habits that keep your card details safe
Card choice only matters up to a point. These habits do as much work as the card itself:
- Keep the device you shop from updated, and use a different password for banking than for your other logins.
- Turn on multi-factor authentication wherever it is offered. Our guide to multi-factor authentication shows how easy it is to set up.
- Shop with sellers you know, and read independent reviews that are not on the seller’s own site. Watch for look-alike websites that imitate a business you trust.
- Avoid sending card details over public Wi-Fi. Save payments for a trusted network.
- Do not save your card details in online shopping accounts.
- Check your statements and your credit report regularly so you notice a problem early. If your details surface in a breach, our guide to what to do after a data breach walks through the next steps.
- Stay alert to scams more broadly. Our guide to spotting and reporting scams covers the warning signs and what to do if you have been caught.
Before your next online order, spend five minutes turning on multi-factor authentication for your banking app and checking your card provider’s dispute rules.
Your questions answered
Q: Is a credit card always safer than a debit card online?
A: For fraud and disputes, usually yes, because fraudulent charges do not touch your own money. But a debit card with a very low balance can limit your losses just as effectively, and it avoids the risk of interest and debt.
Q: How long do I have to dispute an online purchase?
A: Chargeback time limits usually run 45 or 120 days from the purchase, but the exact rules vary by card provider. Contact your bank as soon as you notice a problem.
Q: Can I get a chargeback if I paid through PayPal?
A: Generally no, because PayPal purchases sit outside card chargeback schemes. PayPal runs its own in-house protection, and you have 180 days from payment to open a dispute on its website.
Q: Should I use buy now, pay later instead of a card?
A: It is a separate credit arrangement with its own dispute process, so raise problems with the provider first. If you pay instalments from a card, you may be able to start a chargeback on that card, though your bank might not agree.
