Staying connected in Australia.

Australia is a long-trip destination, which makes the roaming math worse than it looks. AT&T and Verizon day passes run about 10 to 12 dollars a day, so a week is around 70 to 84 dollars and the two or three weeks most people spend here turns into a few hundred dollars for data you can buy far cheaper. T-Mobile is the exception worth checking first: its current tiers include a genuine high-speed allowance abroad, roughly 5GB on Experience More, Magenta MAX and Go5G Plus, 15GB on Experience Beyond and Go5G Next, and 30GB on Better Value, slowing to 256kbps only once that is used up. The entry Essentials tier is the one throttled from the start. Google Fi and Visible set their own terms, so read your own plan rather than assuming.

The trap to avoid entirely is roaming with no plan. Pay-per-use data runs about 2 dollars a megabyte, thousands per gigabyte, and phones use data in the background without being asked, so turn off data roaming until your eSIM or pass is live. Physical prepaid SIMs are easy to buy in Australia at airports, supermarkets and phone shops if you prefer one, but for a normal trip an eSIM saves you the errand on your first jet-lagged morning.

A travel eSIM is the cheapest way for most visitors to get real data. A Nomad eSIM is a few dollars per gigabyte, well under day-pass pricing, and it activates before you fly and works from landing, with no shop visit and no Australian paperwork. Your US number stays reachable on your usual plan while the eSIM carries the data.

In Sydney or Melbourne, the underlying network hardly matters. Outside them it matters a lot, and this is the one country in our guides where we would tell you to check. Telstra has the widest reach by a clear margin and is the network to want in the country, Optus is solid across the populated areas, and Vodafone, now part of TPG, is competitive in the cities and thinner beyond them. If your trip includes a long drive, a national park, a remote coastal town or anything resembling the Outback, favour a Telstra-backed plan and treat the extra dollar or two as cheap insurance. Telstra publishes a coverage map you can search by address or coordinates, which is worth ten minutes if your route is ambitious, keeping in mind that such maps predict outdoor coverage rather than guarantee it.

Australian coverage follows the population, which lives around the edge. In the cities, along the coast and in the main regional towns you get fast 4G and 5G in the bigger centers. In the remote interior, the gaps are not the few-minutes kind familiar from a European mountain pass: on outback highways you can be out of range for hours of driving, and small settlements may have a single carrier or none. Long stretches of the Nullarbor, the central deserts and remote parts of the north are simply not covered by anyone.

Plan for it rather than trying to buy your way out. Download offline maps and anything you need to read before you leave a town, tell someone your route on a long drive, and remember that a phone with no signal cannot summon a tow truck. If you are going properly remote, the carriers sell satellite messaging and satellite handsets for exactly this, which is the serious answer for a serious trip. For everyone else, the practical version is that coverage is excellent where you will actually spend your time. This guide is written for US travelers departing the US.

More on Australia

The little money things nobody warns you about.

• Driving in Australia: tolls, fees and the excessTwo things decide what driving in Australia costs you, and neither is the daily rate. One is how your rental company handles tolls, which varies more than almost anything else. The other is the excess buried in the agreement.
• Taxis in Australia, and the apps to useGetting around Australia is easy: Uber and its rivals are everywhere, taxis are metered and effectively cashless, and you do not tip. The one quirk is a small card surcharge. Here is how it works.
• Do I need cash in Australia, or can I use cards?Short answer: almost never. Australia is one of the most cashless countries anywhere, so you can tap for nearly everything. Here is how to handle it, including the card surcharge you may see.
• Tipping in AustraliaAustralia is not a tipping country. Staff earn a high minimum wage, so tipping is not expected anywhere, and you can relax about it. A small tip for exceptional service is optional. Here is what you actually owe.
• How do US citizens get an Australia ETA?Short answer: through the official app, and only the app. US citizens need an Australian ETA, it is cheap and usually instant, but the app-only process trips people up. Here is how it works and what it costs.
• Bringing your dog or cat to Australia.Australia has the strictest pet import process of any English-speaking country, and it is the most expensive move we cover. Two numbers frame it: a lead time of at least 6 to 7 months, set by a rabies test and a fixed 180-day wait, and an all-in cost that often reaches five figures. Here is the order, the official route, and where the money goes.
