Best eSIM for Australia 2026: Which Plan is Worth It?

Australia's domestic networks are dominated by Telstra and Optus. Telstra has the wider rural coverage — important if you're driving the Great Ocean Road or heading into the Outback. For a city-focused trip (Sydney, Melbourne, Brisbane), either network is fine and the coverage difference doesn't matter.

One thing to check before buying

Australia is big. If your itinerary goes beyond the coastal cities — Uluru, the Kimberley, Tasmania — check which local network the eSIM uses before buying. Telstra coverage maps are publicly available and worth a quick look.
