Emergency Services Telecommunications Authority (ESTA) provides life-saving emergency call-taking and dispatch services for all Victorians. ESTA needed an upgrade to their paging network to ensure the reliability of emergency services communications across Victoria.

Emergency Alerting Service (EAS) is a sophisticated, purpose-built and fully redundant emergency services communications network, comprising satellite links, optic fibre links, wireless ground base stations and robust monitoring and feedback systems, used to transmit emergency alerts.

Ventia designed, constructed and installed ESTA's mission critical EAS network, and performs ongoing operations and maintenance services providing safer and more responsive emergency alerting across the State.

The project covered 228 transceiver sites, providing extensive coverage of Victoria.
