Dubbo is one of three NSW sites where the special phones will be trialled.

The devices are shock-proof, waterproof and dust-resistant and function more efficiently than satellite phones in many environments.

The two other trial sites are Bateau Bay and Batemans Bay.

Health Minister Brad Hazzard on Wednesday joined NSW Ambulance’s Acting Executive Director Operational Logistics, Peter Elliott, and paramedics at the Bateau Bay Ambulance Station to announce the trial.

Two hundred vehicles will be fitted with the high-tech devices as part of an ongoing $35 million  investment in radio and critical telecommunications, Mr Hazzard said.

“Every second counts in an emergency and a reliable communication channel could mean the difference between life and death for a patient,” Mr Hazzard said.

“These smartphones are a smart investment and will ensure paramedics have undisrupted phone connection at all times and can respond faster and with confidence in any weather condition from any corner of the state.”

Mr Elliott said the smartphones will complement existing radio communications to provide paramedics with multiple communications tools, under the revolutionary Vehicle Area Network program.

“The Vehicle Area Network program brings four radio and satellite networks into one communication hub to overcome communications challenges presented by the varying terrains and topographies across NSW,” Mr Elliott said.

“This hub streamlines communications by providing one access point for calls or communications made or accessed by paramedics in the field.”

The NSW Government’s $35 million investment includes new in-vehicle and portable radios, upgrades to regional ultra-high frequency infrastructure, new mobile data terminals for vehicles and a new, long range digital radio network for isolated regions.
