000 or 112 ???
There is no doubt that 112 is connected and a mobile telephone will make that call even if the phone has no SIM card. 112 and 000 may be treated as equivalent FOR CALLS FROM MOBILES only
All about Emergency Calls, the Legislative framework and how the system works go to ACMA – Australian Communication and Media Authority
The Telecommunications (Emergency Call Persons) Determination 1999 specifies both Telstra Corporation Limited and the National Relay Service (NRS) provider as national operators of emergency call persons who operate the Emergency Call Service.
Telstra has the responsibility of providing the service which answers calls to the emergency service numbers Triple Zero (000) and 112, and transfers them, with relevant associated information, to the requested emergency service organisation.
