The usual advice for homeowners to stay and defend their properties or to seek refuge elsewhere will be revised to put far more emphasis on leaving early.

“We’ll be providing more information to the community, like Twitter and Facebook – alternative means of communication to get the information out to the public,” Mr Brumby said.
