How do you get a mobile phone plan in Australia in 2026?

Telstra, Optus, and Vodafone dominate national coverage, with smaller MVNOs riding those networks. Airport and city stores sell prepaid starter packs. eSIM options work if your handset is unlocked and supports Australian bands. Activation requires identity verification under federal prepaid ID rules. Non-residents usually need an international passport. Carriers also ask for an Australian residential address; a hotel or temporary lease is commonly accepted for activation.

Activation often works more cleanly after you have entered Australia so passport and visa details can verify. Keep the SIM packaging and the phone number you activate. You will reuse that number for myGov, TFN, and bank one-time codes. Coverage is strong in capitals and thinner in some remote stretches: Utilities, internet, and transport.

Postpaid or SIM-only contracts usually want a visa that covers the plan term, Australian address proof, and a successful credit assessment. If you are on a short visitor stay, prepaid is the safer default. Once you have a longer visa, utility bill, or lease, upgrade if you want handset financing or larger data buckets.

Update the carrier when you change address so bills and identity records stay aligned: Update your address. Do not port or cancel a number that is still linked to banking or government accounts until replacements are tested.
