ESTA People


Prior to 1969, Australia did not have a national number for emergency services; the police, fire and ambulance services possessed many phone numbers, one for each local unit.

Operational Communications

ESTA is dedicated to providing quality community safety services through the provision of 24 x 7 world-class emergency telecommunications services which support the emergency services organisations’ response to the needs of the Victorian community.

The Mobile Data Network (MDN)

The MDN is a digital data switching and radio transmission system integrated with the ESTA Call-taking and Dispatch (CTD) and Victoria Police law enforcement databases. It enables data to be transmitted between these databases and mobile and fixed terminals in Victoria Police and Ambulance Victoria vehicles and offices in the greater Melbourne region. Visit this link to view more information on the Mobile Data Network.

The Emergency Alerting System (EAS)

The EAS is a dedicated messaging system which enables the Country Fire Authority (CFA), State Emergency Service (SES) and Ambulance Victoria (AV) regional emergency services staff and volunteers to be simultaneously alerted to incidents and provided with text messages by means of pocket pagers.

The Metropolitan Mobile Radio (MMR)

The MMR network is a digital radio system providing secure high quality voice communications for Victoria Police, Ambulance Victoria (AV) and Metropolitan Fire Brigade (MFB) over the greater Melbourne region. The network also forms an important part of ESTA Call-taking and Dispatch operations and some 8000 fixed portable and mobile (vehicle based) radio sets are in use. View more information on the Metropolitan Mobile Radio.
