It turns out that many Australians are paying far more in credit card interest than they need to. In fact, research shows Aussies collectively shelled out an estimated $1.6 billion in unnecessary interest in 2025 — and it’s all due to the tendency to stick with high-interest credit cards without reviewing their options. The staggering figure was revealed in a recent survey by finance comparison site Canstar, which highlights how much Australians are losing by simply not shopping around for better credit card deals.
Why Are Australians Paying So Much in Interest?
You might be wondering how this happened. Well, a third of Aussies have never bothered to review their credit cards or switch to a better deal, according to the research. The rest of the respondents weren’t much better — nearly half of those surveyed hadn’t checked their cards in over a year. Can you imagine that? It’s like paying extra on your phone bill because you didn’t bother to shop for a cheaper plan.
The reality is that credit card interest rates in Australia can range from 8.99% to a whopping 28.49%. This wide variation means that, if you’re on the higher end of that scale, you could be throwing away a lot of money each year in interest payments. In fact, Canstar’s analysis showed that Australians collectively paid over $3.4 billion in credit card interest last year. Had they switched to cards with lower rates, they could’ve saved an estimated $1.6 billion, reports 9News. That’s a lot of money that could have been spent elsewhere or saved for a rainy day.
The Hidden Cost of ‘Loyalty’
One of the biggest reasons Australians are stuck with these high-interest cards is their loyalty to them. According to Sally Tindall, Canstar’s data insights director, this “set and forget” mentality is costing people dearly. Many people don’t realize that simply staying loyal to their card provider without reviewing their rates can result in paying unnecessarily high fees over time.
The concept of a “loyalty tax” comes into play here. Consumers continue to use the same card, year after year, without comparing the available options. This can lead to a situation where they’re paying more in interest than they should. But don’t worry — it’s not all doom and gloom. A quick review could potentially save hundreds, if not thousands, over the years.
What Can You Do to Avoid This?
The good news is that it’s never too late to make a change. Experts suggest that Australians review their credit cards at least once a year to ensure they’re getting the best possible deal. A simple annual check-up could prevent you from overpaying in interest or falling into the trap of paying for rewards points that don’t really add up.
Here’s a simple strategy: compare interest rates, fees, and rewards points. If you find a better deal, make the switch. And don’t forget to factor in any additional costs or hidden fees. If you’re using a rewards card, make sure the points are worth more than the interest and fees you’re paying. Otherwise, it might be time to switch to a card with a lower interest rate.
Why Does This Matter?
The big takeaway here is that Australians are leaving money on the table by not reviewing their credit cards regularly. Whether you’re saving for something big or just trying to ease your financial stress, taking a few minutes to find a better deal could lead to big savings. It’s all about staying proactive, and in today’s fast-paced world, it’s worth staying on top of things — your wallet will thank you for it.
