Ambulance Victoria primarily utilises two forms of radio communication to service the state of Victoria.

With Ambulance Victoria servicing both metropolitan and rural areas of Victoria each has its own communication needs.

The metropolitan area is serviced by the Metropolitan Mobile Radio (MMR) Network and its rural counterparts make use of the State Mobile Radio (SMR) Network.

In addition to the state employed Ambulance Victoria entity the state government also makes use of several privately managed Ambulance Service providers’ for non-emergency patient transport (NEPT). These companies also make use of the above mentioned communication networks and in some instances their own company owned networks.

Ambulance Victoria is due to migrate to the Regional Mobile Radio (RMR) Network for its rural communication needs at which point it will no longer use the SMR Network.

Update: As of 11th July, 2019 ESTA and Ambulance Victoria have encrypted all talkgroups on the MMR Network.
