Money in Australia: Cards, Cash, Surcharges and Currency
Cards cover most everyday spending in Sydney and Cairns, but the final amount can still change through surcharges, ATM fees, exchange rates and hotel deposits. Prepare two payment methods and understand when AUD cash still helps.

Use cards for routine spending and cash as backup
Contactless Visa and Mastercard payments are common at hotels, restaurants, supermarkets and transport gates. Do not travel with only one card: fraud controls, damage, a lost wallet or an offline terminal can make a normally reliable card unusable.
A small amount of Australian cash can cover markets, tips where you choose to give one, a broken terminal or a business that applies a card minimum. Split cash and cards between secure places rather than carrying the whole budget together.
Card surcharges are changing in October 2026
For purchases before 1 October 2026, Australia’s current rules can allow a business to pass on the cost of accepting a card, but not more than that cost. From 1 October 2026, new network rules prohibit surcharges on many Visa, Mastercard, American Express and eftpos consumer transactions. Weekend and public-holiday service surcharges are different and can still appear.
The Australian Competition and Consumer Commission explains the transition in its current card-surcharge guidance. Check the amount shown before tapping, especially around the changeover date.
Pay in AUD when comparing conversion choices
A terminal or ATM may offer to convert the transaction into your home currency. That service sets its own exchange rate and can hide the cost inside the converted amount. Paying in Australian dollars usually leaves conversion to your card provider, whose rate and fee you can compare in advance.
Record major bookings in AUD, then convert the same total with each candidate card. This prevents a favourable-looking home-currency display from distorting the comparison.
Check ATMs, deposits and pre-authorisations
- Your card provider may charge a cash-withdrawal fee and interest
- The Australian ATM operator may add a separate fee
- Your home bank may apply a foreign-exchange margin
- Hotels and rental companies may hold a deposit temporarily
A pre-authorisation is not necessarily a completed charge, but it reduces available balance until released. Use a card with enough headroom and do not assume the hold disappears at checkout.
Where Wise can fit
Wise can hold and convert several currencies and may provide a physical or digital card, but card availability and fees depend on the reader’s country of residence. Check eligibility before treating it as part of the travel plan.
If it is available where you live, Wise is one option to compare for AUD conversion and card spending. It should sit beside a second independently issued card, not replace every backup.
Our Wise card guide for Australia covers availability, conversion, ATMs and what we would still carry separately.
Build a simple payment setup
- Check foreign-purchase, ATM and exchange-rate costs on your main card.
- Add a second card from a different issuer or network.
- Keep a modest AUD cash reserve.
- Leave room for hotel or rental pre-authorisations.
- Save issuer phone numbers separately from the wallet.
If medical or cancellation costs would exceed available credit, the Australia travel insurance guide explains why a card benefit and a full policy are different questions.
Frequently asked questions
Can I use cards in Australia?
Yes, especially in cities. Carry a second card and some AUD for failures or cash-only situations.
Should I pay in AUD or my home currency?
Compare the offered rate, but paying in AUD generally lets your own card provider perform the conversion.
Are card surcharges allowed?
The rules change on 1 October 2026. Check current ACCC guidance and the amount displayed before paying; weekend service surcharges are separate.
How much cash should I carry?
A modest backup is enough for most city trips. Do not make cash your only payment method.
Summary
Use a low-cost card for routine AUD spending, keep a separate card and carry a small cash reserve. Check the terminal amount, conversion currency and any surcharge before confirming.
Allow for ATM fees and temporary hotel deposits. The strongest setup is not one perfect card, but two independent ways to pay and enough available balance for the trip.
