Which mobile networks does Australia have?
All three networks cover 98 to 99.5 percent of the population with 4G, but Australia's interior is mostly uncovered by anyone, since people cluster on the coasts.
- Telstra: Telstra has the widest coverage in Australia, reaching 99.5 percent of the population on 4G and 95 percent on 5G, and is the only network that goes deep into the outback.
- Optus: Optus covers 99.1 percent of the population on 4G and 94.5 percent on 5G, and posted the fastest 5G downloads in Opensignal's April 2025 report at over 200 Mbps.
- Vodafone (TPG Telecom): Vodafone reaches 98.4 percent of the population and now roams onto parts of Optus's regional network under a sharing deal approved in 2024, closing much of its old country coverage gap.
MVNO brands like Lebara sell starter packs at Sydney airport, and supermarket SIMs from Coles or Woolworths cost 10 to 15 AUD less than the same packs at the airport.

Is 5G available in Australia?
5G population coverage is high on all three networks: Telstra at 95 percent and Optus and Vodafone both around 94.5 percent, concentrated in cities and large towns.
How much data do you need in Australia?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Australia right now:
eSIM or a local SIM at the airport in Australia?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Australia starts at $23.80 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Australia eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Australia
Australian law requires identity verification to activate a SIM, so have your passport ready when you buy and activate.
Sydney airport has more than 10 SIM outlets across the arrivals halls, including official Vodafone and Optus stores open roughly 6am to 10pm. Tourist packs cost about 30 to 60 AUD, such as a 30 AUD Optus prepaid with up to 35 GB per 28 days, and your passport is used as ID.
For any travel beyond the coastal cities, use Telstra or a Telstra based brand, since it has the largest geographic footprint by far. Optus is a fine cheaper pick if you stick to cities.
Australia Travel eSIM FAQ
Everything you need to know about using an eSIM in Australia
What is the cheapest eSIM for Australia?
Right now the cheapest option ranked by price per GB is MegaEsim with 50 GB for 30 Days at $23.80. That works out to $0.48 per GB. Prices change often, so the table above always shows the current order.
Which networks will my eSIM connect to in Australia?
The plans we compare connect to Optus, Telstra. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Australia eSIMs support 5G?
14 of the 14 plans we track for Australia include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I top up my Australia eSIM if I run out?
Yes. 14 of the 14 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
How many GB do I need for a week in Australia?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is MegaEsim at $3.78.
