How much data do you need in Australia?

For a typical trip to Australia: 1 GB covers a few days of maps, messaging and the odd lookup; 3–5 GB suits a 1–2 week trip with regular browsing and social; choose an unlimited plan if you stream, hotspot a laptop, or rely on video calls. Wi‑Fi in hotels and cafés will stretch any plan further.

Mobile networks in Australia

Australia's main mobile networks are Telstra, Optus and Vodafone. Most travel eSIMs for Australia connect to one of these, so coverage matches a local SIM — 4G/LTE is widely available and 5G is live in the larger cities.

How to set up your Australia eSIM

  1. Check compatibility — most phones since ~2018 (recent iPhone, Pixel, Samsung Galaxy) support eSIM and are carrier-unlocked.
  2. Buy a Australia plan from a provider above before you travel.
  3. Install the eSIM by scanning the QR code or tapping the in-app install — do this on Wi‑Fi.
  4. On arrival, turn on data roaming for the eSIM line. You're online without hunting for a local SIM.
