Key takeaways
Australia has fast 5G in cities but real coverage gaps in the Outback. The easiest way to stay online is a Roamix Australia eSIM, which connects to the strongest local network the moment you land, with no roaming fees and nothing to collect. Plan 10 to 15 GB for a two week trip and always cache offline maps for remote drives.
- Telstra has the widest coverage and is the only network to trust in the Outback.
- A Roamix eSIM activates automatically on arrival, so you skip SIM kiosks and roaming bills.
- Australia is largely cashless, so a connected phone wallet matters more than carrying notes.
- Most visitors need an ETA or eVisitor authorisation arranged online before arrival.
- Budget 10 to 15 GB of data for two weeks, more if you tether or take video calls.
Best way to get data in Australia
For nearly everyone visiting Australia, a Roamix eSIM is the simplest and cheapest way to stay online, with local network speed and no surprise roaming charges.
| Option | Best for | Good to know |
|---|---|---|
| Roamix eSIMRecommended | Best for: Most travellers | Instant activation, local network speeds, no roaming bill, and nothing physical to collect or return. |
| Local physical SIM | Best for: Long stays needing a local number | Cheap data but requires ID, a store visit and swapping out your home SIM. |
| Pocket wifi | Best for: Groups sharing one connection | Another device to charge and return, with deposits and daily fees. |
| Carrier roaming | Best for: Very short trips with no setup time | The most expensive option, often charged per day or per MB. |
Free wifi is common in cafes, libraries, shopping centres and most hotels, but speeds vary and public networks are not secure for banking. It is a supplement, not a substitute for mobile data.
How much data you need
How much data you need in Australia depends on how much driving and streaming you do. Maps and rideshare are light, but offline map downloads, video and hotspot use add up fast on a multi week trip.
3 to 5 GB
Short city break, navigation and messaging
Maps, rideshare, social and email over a long weekend in one or two cities.
10 to 15 GB
Two week east coast road trip
Heavy navigation, bookings on the move and regular photo and video sharing.
20 GB or more
Remote work or hotspot use
Video calls, tethering a laptop and cloud uploads across several weeks.
Data per hour, by activity
- Maps and navigation
- 5 MB
- Social media and browsing
- 100 to 150 MB
- Music streaming
- 70 MB
- Standard video streaming
- 700 MB to 1 GB
- Video calls
- 500 MB to 1.5 GB
Download offline maps of the Outback and national parks over wifi before you leave the city, which saves data and keeps you oriented where there is no signal at all.
How to set up a Australia eSIM
Setting up a Roamix Australia eSIM takes a few minutes and is best done over wifi before you fly. You install it once, then it activates automatically when you connect to an Australian network on arrival.
- 1
Buy your plan on the Roamix Australia eSIM page before departure.
- 2
Scan the QR code or tap to install the eSIM over wifi.
- 3
Label it Roamix and keep your home SIM as primary for calls and texts.
- 4
Turn on data roaming for the Roamix line only, which lets it use the local network.
- 5
Land in Australia and the eSIM connects automatically, no kiosk required.
Works on eSIM capable phones including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S and Note models. The phone must be carrier unlocked.
Roamix configures the correct APN automatically on most devices. If data does not start, set the APN manually using the details on your order and toggle airplane mode.
If you have no data on arrival, confirm data roaming is on for the Roamix line, select the network manually in settings, and restart the phone.
Visa and entry for Australia
Most tourists need an electronic travel authority arranged online before flying. There is no visa on arrival for general tourism.
- eVisa or ETA
- Eligible passport holders apply for an ETA, while others use the eVisitor authorisation, both done online before departure.
- Passport validity
- Carry a passport valid for the duration of your stay and check airline specific validity rules.
- Onward ticket
- Proof of onward or return travel and sufficient funds may be requested on arrival.
Keep digital copies of your ETA and passport accessible offline, and use your Roamix eSIM to show any required documents at the border.
Entry rules change. Always confirm current requirements with the Department of Home Affairs before booking.
When you land in Australia
0 of 5 done
How people message here
Australians use a mix of SMS, WhatsApp, Messenger and iMessage. There is no single dominant chat app, so WhatsApp covers most situations.
Do you need a local number?
You rarely need a local number. Rideshare, bookings and most services accept your existing number, and a Roamix data line is enough for app based calling.
Keep your home SIM active for SMS based two factor codes while using the Roamix eSIM for data.
Airports in Australia
SYD
Sydney Kingsford Smith International
Sydney
Free WiFi available across T1 international terminal. Speeds are adequate for messaging but slow during peak arrivals.
Activate your Roamix eSIM before boarding so you land already connected on Telstra 5G and can book a train or rideshare straight from the gate.
MEL
Melbourne Tullamarine Airport
Melbourne
Free WiFi available at all terminals. International terminal coverage is good.
There is no rail link from Melbourne Airport, so an active eSIM lets you compare SkyBus, taxi and rideshare prices the moment you exit customs, with Telstra 4G navigation ready for the Great Ocean Road.
BNE
Brisbane International Airport
Brisbane
Free WiFi offered across the international terminal. Connectivity is reasonable for downloads.
Brisbane is the launch point for Gold Coast, Sunshine Coast and Great Barrier Reef tours from Cairns. Download offline maps for your Queensland itinerary while you wait at the gate.
PER
Perth International Airport
Perth
Free WiFi in the terminal. Coverage can be patchy in the outer gates.
Perth is one of the world's most isolated major cities. Roamix on Telstra 5G connects immediately on arrival, so you can grab an Uber, check Margaret River winery hours and message your accommodation without delay.
Apps and internet access in Australia
Australia has an open internet, so every common app works normally on a Roamix eSIM.
There is no general censorship of social media, messaging or search. You do not need a VPN to use any mainstream service.
WhatsApp, works
Fully available for messaging and calls.
FaceTime, works
Works normally over data and wifi.
Google Maps and Search, works
No restrictions.
Social media, works
Instagram, Facebook, TikTok and X all work.
Getting around Australia
Australia mixes world class city transit with vast self drive distances. Most ways of getting around now assume you have data for apps, tickets or navigation.
City public transport
Sydney, Melbourne and Brisbane use contactless tap on with bank cards or transit cards. A connected phone lets you check live timetables and plan routes.
Rideshare and taxis
Uber, DiDi and Ola operate in all major cities and need an active data connection to book and track rides.
Self drive road trips
Essential for reaching most of the country. Use live navigation in coverage areas and always cache offline maps for remote stretches.
Domestic flights
The practical way to cross the continent. An eSIM lets you check in, store boarding passes and rebook on the move.
Major cities use tap and go contactless travel cards or direct bank card tap on public transport, so keep your connected wallet handy.
Money and payments in Australia
Australia is largely cashless. Tap to pay works almost everywhere, so a connected phone wallet is more useful than carrying AUD notes.
- Cards and cash
- Cards and phone wallets are accepted nearly everywhere. Carry a small amount of cash only for rural markets and tips.
- ATMs
- ATMs are widespread in towns. Choose to be charged in AUD rather than your home currency to avoid poor dynamic conversion rates.
- Payment apps
- Apple Pay and Google Pay are widely accepted. A connected Roamix eSIM keeps your wallet and banking apps working on the move.
- Tipping
- Tipping is not expected. Round up for great service if you like, but there is no obligation in restaurants or taxis.
Daily budget
Budget travellers spend around 80 to 120 AUD a day, mid range 150 to 300 AUD, with cities pricier than regional towns.
Local tips for Australia
- Language
- English is the official language, but local slang is heavy. A connected translator app is rarely needed, though it helps with Indigenous place names.
- Food
- Expect world class coffee, multicultural city dining, fresh seafood and a strong brunch culture. Book popular restaurants ahead using an online reservation app.
- Plugs
- 230V, Type I plug
Apps worth having
Opal Travel
transit
Manages public transport fares and top ups across Sydney and New South Wales.
Uber
rideshare
Widely available in all major cities and a reliable backup to taxis.
WillyWeather
weather
Localised surf, tide and UV forecasts, which matter on the coast.
Safety and health in Australia
Australia is very safe for travellers, with the main risks coming from nature rather than crime. Staying connected helps you read official warnings in real time.
- Stay reachable
- Keep your Roamix eSIM active to receive emergency alerts, check fire and flood warnings, and use live maps in unfamiliar areas.
- Health
- Sun and surf are the biggest everyday hazards. Use a weather app for UV and surf conditions, and carry water on remote drives.
- Tap water
- Tap water is safe to drink across the country.
Networks and coverage in Australia
Australia has fast, modern mobile networks in cities and along the coast, but coverage thins quickly inland. A Roamix Australia eSIM connects to the strongest available local network the moment you land, so you get reliable 4G and 5G in Sydney, Melbourne, Brisbane and Perth without hunting for a SIM kiosk or paying carrier roaming fees.
Telstra
The widest reach in the country, and the only network worth trusting in the Outback, regional Queensland and remote Western Australia.
Optus
Strong in metro areas and most coastal towns, with competitive 5G speeds in the eastern capitals.
Vodafone
Good value in dense urban zones but the weakest of the three once you leave major population centres.
- Typical speeds
- Expect 50 to 200 Mbps on urban 5G and 20 to 60 Mbps on regional 4G.
- 5G
- 5G is live across all capital cities and growing in regional hubs.
If your trip includes Outback driving or remote national parks, prioritise a Roamix plan that rides the Telstra footprint, since it is the only carrier with meaningful regional towers.
Outside towns, coverage follows the highways and population. Long stretches of the Nullarbor, the Red Centre and the Kimberley have no signal on any network, so download offline maps before you drive. Australian networks use common LTE and 5G bands supported by most modern unlocked phones, so a Roamix eSIM works on virtually any recent device.
Where to go in Australia
Australia rewards travellers who plan around its size. Distances between highlights are continental, seasons are flipped from the northern hemisphere, and the gap between connected coast and offline interior is real. Staying online with a Roamix eSIM keeps navigation, bookings and live transit updates working as you move between regions.
Best time to visit
September to November and March to May offer mild weather nationwide. Visit the Top End in the dry season from May to October, and the southern snowfields from June to August.
New South Wales
Home to Sydney, the Blue Mountains and a long surf coast stretching from Byron Bay down to the Sapphire Coast. Hunter Valley wine country and Bondi Beach attract millions of visitors each year.
- Sydney Opera House
- Bondi Beach
- Blue Mountains
- Hunter Valley
- Byron Bay
Excellent 5G across Sydney and the coastal corridor, with usable signal in most Blue Mountains towns and Telstra 4G reliable along the Pacific Highway.
Victoria
Melbourne consistently ranks among the world's most liveable cities. The Great Ocean Road, the Grampians National Park, and the Mornington Peninsula round out Victoria's appeal for road trippers.
- Federation Square
- Great Ocean Road
- Grampians National Park
- Mornington Peninsula
- Dandenong Ranges
Dense 5G across Melbourne's CBD and inner suburbs. Great Ocean Road has good Telstra 4G to Apollo Bay, patchy beyond. Grampians Visitor Centre in Halls Gap is covered.
Queensland
Tropical north, the Great Barrier Reef, the Daintree Rainforest, Whitsunday Islands and the Gold Coast theme parks. Brisbane anchors a tourist corridor stretching 1,500 km up the coast.
- Great Barrier Reef
- Daintree Rainforest
- Whitsunday Islands
- Gold Coast
- Noosa
Reliable along the coast and in Cairns, Brisbane and the Gold Coast, but reef boats and the deep Daintree Rainforest often lose signal.
Western Australia
Perth is one of the world's most isolated major cities. Margaret River wine country sits two hours south, while the Kimberley and the Pinnacles Desert define remote Australia at its most dramatic.
- Fremantle
- Margaret River
- Pinnacles Desert
- Broome
- Kimberley
Strong Telstra coverage in Perth and Margaret River. Broome has Telstra 4G. The Gibb River Road through the Kimberley has coverage at townships only, with long off-grid stretches between.
Northern Territory
Uluru, Kakadu National Park and Alice Springs. The spiritual heart of Australia and home to some of the oldest Indigenous cultures on Earth, with Darwin as the tropical gateway.
- Uluru (Ayers Rock)
- Kata Tjuta
- Kakadu National Park
- Kings Canyon
- Alice Springs Telegraph Station
Alice Springs and Darwin have Telstra 4G and some 5G. The Yulara resort area at Uluru has Telstra 4G. Kakadu visitor areas are covered, but remote tracks are off-grid.
Off the beaten path
One of Australia's last great four wheel drive adventures, ending at the northernmost tip of the mainland.
Signal: Only patchy signal in a handful of communities and no coverage along most of the track.
Iconic coastal drive past the Twelve Apostles, surf beaches and rainforest waterfalls.
Signal: Generally good signal in towns and at major lookouts, with short dead spots between them.
Some of Australia's most dramatic gorge swimming. Hancock Gorge, Weano Gorge and Knox Gorge descend 100 metres into ancient red rock and are largely unknown outside Western Australia.
Signal: No mobile coverage within the gorges. Tom Price, the nearest town 90 km away, has Telstra 4G. Download offline maps, emergency plans and gorge route information in Tom Price before entering.
The most southerly point of mainland Australia, with pristine white beaches, wombats wandering campgrounds at dusk and hiking trails that reward serious walkers.
Signal: Telstra 4G at Tidal River campground. Trails on the southern headlands drop to no signal. Squeaky Beach and Norman Beach have intermittent coverage.
World class snorkelling and swimming with whale sharks from March to August, far less crowded than the Great Barrier Reef and with easier water access directly from the beach.
Signal: Telstra 4G in Exmouth and Coral Bay. No coverage on boat trips to the outer reef. Whale shark season tour operators rely on satellite communication offshore.
The world's largest sand island, with freshwater lakes including the iconic Lake McKenzie, wild dingo populations and a towering coloured sandstone formation called The Pinnacles.
Signal: Telstra 4G at Kingfisher Bay Resort and Happy Valley. The eastern beach and some inland tracks have intermittent coverage. Four-wheel-drive only island; always check track conditions before departure.
Ancient mountain ranges, 600-million-year-old geology and the ghost gum corridors at Wilpena Pound. Less visited than the Red Centre but equally dramatic.
Signal: Telstra 4G in Hawker and Quorn. Wilpena Pound Visitor Centre has limited Telstra coverage. Remote gorges and the ABC Range hiking tracks go off-grid.
Dramatic sandstone ranges, ancient Aboriginal rock art at Brambuk Cultural Centre and the famous MacKenzie Falls, all a two-hour drive from Melbourne.
Signal: Telstra 4G in Halls Gap village. Balconies Lookout and Boroka Lookout trails have coverage. Remote camping zones in the northern Grampians have limited signal.
El Questro Gorge, Emma Gorge and Zebedee Springs are among Australia's most stunning swimming holes, accessible only by four-wheel-drive and one of the last true wilderness frontiers.
Signal: Limited Telstra coverage at El Questro Station homestead and Emma Gorge Resort. The Gibb River Road between gorges has no coverage for many hours of driving. Satellite communication is essential.
A UNESCO World Heritage island in the Tasman Sea with a permanent population of just 400 people, world class diving on the southernmost coral reef in the world and only 400 visitor spots per day.
Signal: Telstra limited service only. Visitors typically have slow 4G data in the township and along the main road. Ball's Pyramid and Mount Gower trail have minimal signal.

Working remotely from Australia
Australia is excellent for remote work in cities, with fast fixed and mobile internet and abundant coworking, though the time zone is challenging for European and American teams.
- Connection
- Urban 5G easily supports video calls and tethering. A Roamix data plan with 20 GB or more covers a working week of calls and uploads.
Cafes and libraries offer reliable wifi, but use your eSIM as a secure backup for sensitive work on public networks.
