So, you’re headed Down Under and wondering what kind of plastic or paper you’ll be shoving into your wallet. Or maybe you're just curious about how things work in a country that basically invented "indestructible" money.
The short answer is the Australian dollar (AUD). Simple enough, right?
But honestly, the way Australians use their money in 2026 is a weird mix of ultra-high-tech digital habits and a brand-new government obsession with keeping physical cash alive. If you just show up with a pocket full of US dollars or British pounds, you're going to have a bad time.
The Basics: What is the Australian Dollar?
Australia uses the Australian dollar, which is divided into 100 cents. You’ll see it written as $, A$, or AU$. It’s one of the most traded currencies in the world—usually sitting right around the fifth spot—mostly because Australia sells a massive amount of iron ore, coal, and gold to the rest of the planet.
When you look at the physical money, it’s vibrant. Like, really vibrant.

The "Plastic" Banknotes
Australia was the first country to introduce polymer (plastic) banknotes back in 1988. They don’t tear. They don’t turn into mush if you leave them in your board shorts and go for a surf. They even have clear "windows" in them that are nearly impossible for counterfeiters to copy.
Here is the current lineup of what you'll find in your hand:
- $5 (Pink/Purple): Traditionally featured Queen Elizabeth II, but as of 2026, the Reserve Bank of Australia (RBA) is in the middle of a transition to a new design honoring Indigenous culture.
- $10 (Blue): Features poets Banjo Paterson and Mary Gilmore. Look for the tiny "microprint" of their poems if you have a magnifying glass handy.
- $20 (Red/Orange): This one is nicknamed a "lobster." It features Mary Reibey and John Flynn (the guy who started the Royal Flying Doctor Service).
- $50 (Yellow): Known as a "pineapple." It features David Unaipon, a legendary Indigenous inventor, and Edith Cowan.
- $100 (Green): The "Granny Smith." It's the rarest one to see in the wild because most people use cards for big purchases.
The Coins (They’re Heavy)
Australian coins are a bit of a workout for your pocket.
- 5c, 10c, 20c, 50c: These are "silver" (cupro-nickel). The 50-cent coin is a massive, twelve-sided monster. It’s heavy enough to use as a paperweight.
- $1 and $2: These are "gold" (aluminum-bronze). Weirdly, the $2 coin is smaller than the $1 coin, even though it’s worth more. You’ll get used to it.
The Big 2026 Change: The Cash Mandate
Here’s where things get interesting. For the last decade, Australia was sprinting toward becoming a cashless society. In 2022, only about 13% of transactions were made with cash.

But as of January 1, 2026, the Australian government stepped in with a new rule.
Most businesses selling "essential" goods—think groceries and petrol—are now legally required to accept cash again. Why the backtrack? Basically, the government realized that if the internet goes down or a bushfire knocks out the power, people can't buy food. Plus, older Australians and those in remote Outback towns were getting left behind. So, while you can tap your phone for almost everything, you now have the right to pay in cold, hard cash at places like Coles, Woolworths, or a 7-Eleven, provided the transaction is under $500.
Do You Actually Need Cash?
Kinda. But mostly no.
If you’re staying in Sydney, Melbourne, or Brisbane, you can go weeks without touching a coin. Australians love "Tap and Go." Whether it’s a credit card, a debit card, or Apple/Google Pay on your watch, it’s the default. Even the guy selling sausages at a local "Sausage Sizzle" outside a hardware store will likely have a Square reader.

When Cash is Still King
- Small Cafes: Some tiny "hole-in-the-wall" coffee shops in regional areas might have a $10 minimum for cards.
- Local Markets: While many vendors take cards, the connection in a crowded park can be spotty.
- Emergency Backup: If you're driving into the Red Centre or through the Great Ocean Road, phone reception vanishes. No bars means no "tap." Keep fifty bucks in your glove box.
The "Surcharge" Trap
Something that catches tourists off guard is the "surcharge." In many countries, the price you see is the price you pay. In Australia, if you pay by card, many businesses will add a small fee—usually between 0.5% and 1.5%—to cover the bank's processing costs.
It’s totally legal. They just have to display a sign saying they do it. If you want to avoid this, use cash. That's why the $50 "pineapple" is making a bit of a comeback in 2026; people are getting tired of those 15-cent fees adding up on every flat white they buy.
60 Years of the Dollar: 1966–2026
If you happen to look at your change this year, you might see some special coins. February 14, 2026, marks exactly 60 years since Australia ditched the old British-style pounds, shillings, and pence.
Before 1966, the math was a nightmare. 12 pence to a shilling, 20 shillings to a pound. The switch to a decimal system (100 cents = 1 dollar) was a massive cultural moment. The Royal Australian Mint has released a bunch of anniversary coins to celebrate, so keep an eye out for any shiny $1 coins with "60 Years" stamped on them—they’re already becoming collector's items.
Practical Money Tips for Your Trip
- Round to the nearest 5 cents: Australia doesn't have 1-cent or 2-cent coins anymore. If your bill is $10.97, and you’re paying cash, you’ll pay $10.95. If it’s $10.99, you pay $11.00. If you pay by card, you pay the exact $10.99.
- Tipping is not required: Honestly. The price on the menu includes tax (GST) and the staff are paid a decent living wage. If the service was incredible, feel free to leave 10%, but nobody will chase you down the street if you don't.
- ATM Fees: Try to use ATMs attached to big banks like ANZ, CommBank, Westpac, or NAB. The random ATMs in the back of a pub will often charge you $5 or more just to see your balance.
- Exchange Rates: As of early 2026, the Australian dollar is trading around 0.67 USD. It’s a "commodity currency," so if the price of iron ore or gold goes up, the Aussie dollar usually gets more expensive too.
Your Next Steps
Before you board your flight, make sure your bank knows you’re heading to Australia so they don't freeze your card the first time you try to buy a meat pie. Download a currency converter app like XE to keep an eye on the daily fluctuations. While the new 2026 cash mandate means you can use cash for essentials, your best bet is still to carry a travel-friendly debit card (like Wise or Revolut) for everyday taps and keep about $100 in physical banknotes for those "just in case" moments in the bush.
