It is also possible to get a Australia Post Mobile eSIM for the same price as a regular SIM card.

You should consider getting a travel eSIM for Australia because they can sometimes be cheaper than getting a SIM card from possible.

Especially if you get an APAC (Asia-Pacific)-wide eSIM or a global eSIM.

I discuss various eSIM options of eSIM providers for Australia in my Australia eSIM buying guide, which are:

  • Airalo: Yes! Go! (Australia only) & Discover+ (125+ countries worldwide + minutes and SMS) – use code NEWTOAIRALO15 (15% off – first-time users only) or AIRALOESIM10 (10% off)
  • Alosim: Australia – use code PTW (5% off – no limits)
  • Holafly: Australia (unlimited data eSIMs) – use code PHONETRAVELWIZ (5% off – no limits)
  • Nomad: Australia, APAC (up to 20 countries), SEA-Oceania (eight countries) & Global (up to 139 countries) – use code ADU123 (3 USD off – first-time users only)

As I said, check out my Australia eSIM buying guide for more information, as I have to continue with possible for now.
