Plan prices, data allowances, validity, and features come from retailer feeds and are refreshed daily. Plans are sorted by lowest price by default, and you can sort or filter by data, trip length, coverage type, and provider. We may earn a commission when you buy through our links, but this does not change the order plans appear in.
The guidance below was checked against provider terms in October 2026. You can compare other destinations on our travel eSIM hub.
Airalo charges in US dollars. We show an approximate price in pounds using a daily exchange rate, so the amount on your statement may differ slightly. Your card provider may also add a fee for paying in a foreign currency.
How much data do you need for Australia?
Trips to Australia tend to be longer than most, so think about data across two or three weeks rather than one. For a fortnight with maps, messaging, social media, and ride-hailing apps such as Uber, 10GB to 15GB is usually enough. Allow 20GB or more if you plan to hotspot a laptop or stream on long coach and train journeys.
If you are driving between cities or heading into the Outback, download offline maps before you set off. Long stretches of highway have no mobile signal at all, so your phone needs the route stored before you lose coverage.
If your trip also takes in New Zealand or the Pacific islands, the Oceania plans on this page cover 12 countries on one eSIM. Some Asia plans on this page also include Australia and New Zealand, which suits a trip with a stopover in Asia. Check the country list before you buy.
Australia is outside the European roaming zones included in most UK plans, so using your UK SIM there usually means a daily charge or pay as you go rates. Check what your network charges before you travel in our roaming guides.
Network coverage in Australia
Australia has three mobile networks: Telstra, Optus, and Vodafone (owned by TPG Telecom). Travel eSIMs usually run on Telstra or Optus. You can check which network a plan uses in the plan details on the provider's site.
Coverage is strong in Sydney, Melbourne, Brisbane, Perth, Adelaide, and along the main coastal routes such as the drive between Sydney and Brisbane. Away from towns, coverage drops quickly, and large parts of the Outback, national parks, and inland highways have no signal on any network. Telstra says its network covers more of Australia than any other, so check which network your plan uses if you are heading off the main routes.
All three networks have switched off 3G. Your phone needs 4G calling (VoLTE) to make calls in Australia, which most phones from the last few years support.
Travel eSIM versus a local SIM in Australia
Telstra, Optus, and Vodafone prepaid SIMs are sold in their own stores, at airport retailers, and in supermarkets. Australian law requires your identity to be checked before a prepaid service is activated, so you will need your passport.
A local prepaid plan often includes more data for the money on a long stay, but it means a store visit and an ID check after a long-haul flight. A travel eSIM installed before you fly works as soon as you land, which many travellers prefer for a trip of three weeks or less.
How to activate your eSIM in Australia
Buy the plan and install the eSIM profile before you travel, while you are on reliable Wi-Fi, using the QR code or the provider app. Check when the plan's validity starts: most start when the eSIM first connects in Australia, but some start on install. Follow the provider's instructions on when to switch the line on.
After arriving, turn on the eSIM line, set it as your data line, and turn on data roaming for the eSIM line. Most travel eSIMs will not connect without it. Turn off data roaming on your UK line so your UK network does not charge you for data.
If there is no connection after a minute, switch airplane mode on and off once. You can keep your UK line on for calls and texts on your usual number, but calls and texts received abroad may still be charged by your UK network. If you are not sure your phone supports eSIM, check our eSIM compatibility guide before you buy.
If your phone shows no service after landing, check that the eSIM line is set to choose a network automatically. Some plans connect only to Telstra or Optus.
Travel eSIM for Australia FAQ
Answers to common questions about using a travel eSIM in Australia.
Will my eSIM work in the Outback?
Only in and around towns. Large parts of the Outback have no mobile signal on any network, so download offline maps and tell someone your route before driving through remote areas.
Will my eSIM work on the Great Ocean Road and in the Blue Mountains?
Mostly, but expect gaps. Both have good signal in towns and lookouts, with dead spots on stretches of road and in valleys between them.
Can I use one eSIM for Australia and New Zealand?
Yes, if you choose a plan that covers both. The Oceania plans on this page do, and so do some Asia and global plans. Check the country list before you buy.
Will my phone work in Australia now that 3G has closed?
For data, yes. For calls, your phone needs to support 4G calling (VoLTE). Most recent iPhones and Android phones do, but check if you have an older or budget model.
Do I get an Australian phone number?
Most travel eSIMs are data only and do not include an Australian number. You can make internet calls with apps such as WhatsApp or FaceTime, or keep your UK line on for calls and texts.
