What's the cheapest option?
TPG, from $12.50/month with 25GB, running on the Vodafone network. Aldi Mobile and Boost Mobile are also good picks (the latter runs on Telstra's network, with better regional coverage).
What if I need the best possible coverage?
Optus and Telstra have the widest coverage in the country, especially outside major cities, but cost more than the budget options riding on the same underlying networks.
Can I buy the SIM before I arrive?
Yes, most are bought online and arrive in 1–3 days, or you pick one up in a physical store as soon as you land. Activation usually takes just a few minutes once you have the physical SIM or eSIM.
