Telstra

Telstra owns and operates Australia's most extensive mobile network, so you get the country's strongest coverage and fastest speeds through a domestic carrier. Prepaid eSIMs for travelers come with data, calls, and SMS. No long-term contract, and you can top up online or at local shops.

If network reliability matters most to you, buying direct from the network owner is the safest choice. Prices are fair, and activation is quick.
