Australia's size makes app advice state-specific rather than national. Install only the transit and hazard apps for the places on your itinerary, and verify Melbourne's current myki and contactless rollout because it is changing during 2026. Cards cover most everyday spending, but as of August 13, 2026, merchants may still add a lawful card surcharge. Keep a little cash and always pay in Australian dollars. Visa rules depend on passport. ETA-eligible travelers must apply outside Australia through the official AustralianETA app, while many European passport holders can instead use the online eVisitor route. Biosecurity rules are strict: declare food, plant, animal and wooden goods, plus rural or animal-used equipment, whenever unsure. On road trips, offline maps do not replace live road closures, weather and fire warnings. Remote routes can have no mobile coverage, so carry water, fuel and a suitable emergency communications plan. Save bookings, insurance details and exact addresses offline. Call Triple Zero (000), or 112 from a mobile, for a life-threatening emergency.
A visitor does not need an Australian payment app.
Use a contactless Visa or Mastercard, preferably one with low foreign-exchange fees, and carry a small cash fallback. The Reserve Bank found cards accounted for 73% of consumer payments during 2025, but cash still matters at some markets, remote businesses and during terminal outages. As of August 13, 2026, merchants may still add a card surcharge that reflects their cost of acceptance. If there is no surcharge-free payment method, the minimum surcharge must be included in the displayed price.
Australia has decided to remove debit and credit card surcharging from October 1, 2026, so older and newer advice can legitimately differ around that date. Always choose Australian dollars if a terminal or ATM offers currency conversion, then let your own issuer perform the conversion. Use the same physical card or the same phone or watch at both ends of a contactless transit journey because each wallet device is treated as a different card. PayID, BPAY, Beem, Afterpay and local bank transfers are resident-oriented systems rather than arrival tools.
A venue that accepts a wallet still depends on the underlying foreign card being supported. Keep notifications enabled in your home banking app and know how to freeze the card. For cash, use a bank-affiliated ATM when practical, read any operator fee before confirming and decline unwanted conversion.
