What number do I call to block my SIM in Australia?

If your number is with a local carrier: Telstra on +61 439 125 109; Vodafone (TPG Telecom) on +61 426 320 000. If your SIM is from your home country, call your own carrier's lost-phone line instead - the local carriers can't block a foreign SIM.

Reporting it to the police

For a theft that is not in progress, call the national Police Assistance Line on 131 444 (or report online via your state police), which gives you an event/report number. Report the loss in the state where it happened. Then phone your carrier to bar the SIM and block the IMEI - the block propagates across all Australian networks.

For your insurance claim: Insurers need the police event/report number from 131 444 or the online report as proof of the theft.

Blocking your SIM

These are Australia's carriers - use them if your number is local. If your SIM is from your home country, call your own carrier's lost-phone line instead; nobody here can block a foreign SIM.

Your embassy

If your passport went with the phone, your embassy or consulate issues the emergency travel document - the local police can't. The official directory of foreign missions in Australia is here: find your embassy ↗. Bring the police report from the step above.

Getting back online

Prepaid SIMs and eSIMs from Telstra, Optus or Vodafone require a passport for identity verification (no Australian ID needed); booths and vending machines sit in international arrivals. Travel eSIMs bought before arrival skip the ID check.
