Fire Definitions
The Warnings and Incidents page uses a number of definitions to categorise and identify a fire / incident.

CFA, MFB and DEPI each have their own fire districts. Find out more.
Name of Fire / Incident
Each incident is given a name by the Incident Controller to assist in management of multiple incidents. The name does not always reflect the exact location of an incident but rather, serves as a marker for our Incident Management Teams.

The following definitions describe the nature of the incident or emergency event.
Bushfire
