A deal between the State Government and Commercial Radio Australia means more than 30 commercial radio stations join the ABC as official emergency broadcasters.

Commercial radio stations to join the ABC include 3AW, 3MP, Fox, Nova and Triple M.

Premier John Brumby said the agreement would deliver emergency messages to a wider, younger, audience and save lives.

Speaking at the Belgrave Heights and South fire station during Community Cabinet on Monday last week, he said the deal ensured an immediate warning would be sent out to communities during a bushfire emergency.

CFA Yarra Area general manager Lex de Man is urging residents to add battery-operated radios to existing fire plans.

"Any new mode of increasing the ability to get messages to the community is a huge plus for the coming fire season."

Mr de Man is keen on television networks to join the emergency broadcast network despite the risk of power outages in an emergency.

Emergency Services Commissioner Bruce Esplin is confident the scope of the agreement will reduce [radio frequency] black-spots and give communities the information they need.

"It's about a one source one message approach - one simple set of language goes out to all emergency broadcasters at the same time.

"This is not just for bushfires, it's for any emergency affecting Victorian communities."

Mr Esplin and the State Government is confident of brokering a similar deal with free-to-air television networks.

ACE Radio managing director Stephen Everett said: "No matter where people live they will be able to access the information they need by listening to the radio station they normally listen to."
