Telstra
Telstra says its network covers more of Australia than any other. Its VoLTE guidance requires a compatible 4G device and Band 28, with Band 3 also used.
Official network information ↗DESTINATION CONNECTIVITY GUIDE
Best eSIM options for Australia
Australia's principal networks are Telstra, Optus and Vodafone. Population coverage figures can hide major geographic gaps, so city breaks and remote road trips require different choices. The 3G shutdown also makes compatible 4G, VoLTE and emergency-calling behavior important for imported phones.

AustraliaAU · OceaniaPRACTICAL RECOMMENDATION
Start with the trip, then choose the plan
For metropolitan travel, compare a travel eSIM on Optus or Telstra with Optus Traveller eSIM. For remote drives, inspect Telstra, Optus and Vodafone maps stop by stop, confirm Band 28 and VoLTE support, and never treat ordinary mobile coverage as emergency infrastructure.
UNDERLYING NETWORKS
Know which local network you are buying access to
A travel provider is not the network itself. Carrier access can change by package.
Optus
Optus offers prepaid eSIM and an arriving-traveller product. Its published population coverage figure does not describe unpopulated remote geography.
Official network information ↗Vodafone Australia
Vodafone supports eSIM across prepaid plans and publishes address-level predicted 4G and 5G coverage.
Official network information ↗● Population coverage is not land-area coverage.
● After 3G closure, imported phones need compatible 4G and VoLTE behavior, not only an eSIM chip.
● Band 28 support is especially relevant outside dense urban areas.
● Remote roads, parks and offshore areas require route-level planning and offline navigation.
