With the heavy rain causing local flooding, up to date information is available at the ABC Mid North Coast local site.
Click the Emergency link, then Weather or Emergency Information.
The Online Resources under the Emergency Information include contact details and information for floods, fires and bushfires, ambulance, SES, police, RTA traffic warnings, health warnings and more.
Under the bushfire information, there is a handy list of things to pack if re-location is necessary. Looks like it would be useful for flood evacuation as well.
