eSIM data plans for Australia

Australia's plans split two ways: fixed data packages on Optus and Telstra networks, and unlimited plans sold by the day on Optus.

Fixed data plans, for defined data use

The fixed data plans run from 1GB over 7 days up to 50GB over 30 days, all on Optus or Telstra 4G and 5G networks. These suit a traveller who has a rough sense of how much data a trip needs, whether that's checking maps and messages on a short stopover or streaming and navigating through a longer stay. If the data runs out before the plan's days do, a top-up on the same eSIM adds more without needing a new install.

Unlimited plans, priced by the day

The unlimited plans run from a single day up to 30 days on Optus, over 3G and 4G. Each day comes at a flat price, so the plan matches however long you're actually in the country rather than a data amount you have to estimate. These carry a fair use policy: past a set amount of use each day, speed steps down for the rest of that day before returning to normal afterward. That makes them a fit for someone who wants a plan sized to their calendar rather than to a data budget, especially over longer stays where per-day pricing evens out.

Hotspot and buying ahead

Every plan, fixed data or unlimited, allows hotspot and tethering, so a single eSIM can share its connection with a laptop or a second device. Validity only starts when the eSIM first connects to a network in Australia, not at purchase, so installing the profile before you fly costs nothing and just means it's ready the moment you land.
