Bushfires in Victoria
The state of Victoria in Australia has had a long history of catastrophic bushfires, the most recent of these, the Black Saturday bushfires of 2009 claiming 173 lives. Legislation, planning, management and suppression are the responsibilities of the Victorian State Government through its departments and agencies including the Country Fire Authority (CFA) and the Department of Environment, Land, Water and Planning (DELWP).
Victoria is divided into nine fire districts as follows:
- Central (includes Melbourne, Geelong and Ballarat)
- East Gippsland
- North Central
- Northern Country
- West & South Gippsland
- Western District
The districts were reconfigured together with weather forecast districts so that they share common alignments. The revised alignments follow Local Government Authority boundaries, except in Yarriambiack Shire. The new alignments came into effect on 3 November 2010. Total Fire Bans & Fire Danger Ratings maps reflect predictions of the relative danger of bushfire conditions in each district and are communicated to the general public through weather forecasts and the Country Fire Authority and Department of Environment and Primary Industries internet sites during the fire season. The ratings are Low-Moderate, High, Very High, Severe, Extreme and Code Red.
A number of agencies are responsible for bushfire suppression in Victoria - the Country Fire Authority (CFA) which is a statewide volunteer-based organisation, the Department of Environment, Land, Water & Planning (DELWP) who are responsible for public land, covering one third of the state and the Metropolitan Fire Brigade (MFB), which covers the metropolitan area of Melbourne.
Once fires have started, the Country Fire Authority give graded warnings through various means to areas of settlements that may be affected by the fire. These warnings are distributed as messages detailing the status of the fire, its potential movements and give advice to residents in areas that may be affected. They are as follows:
- Advice – general information to keep you up-to-date with developments.
- Watch and Act – an emergency threatens you. Conditions are changing and you need to start taking action now to protect your health, life and your family.
- Emergency Warning – You are in imminent danger and need to take action immediately. You will be impacted by the emergency.
- All Clear - Emergency activity in the area has subsided and is no longer a danger to you.
Emergency Alert telephone warnings may be sent in extreme circumstances. Landlines in the emergency area receive voice messages and mobile phones (with a billing address in the emergency area) receive text messages. Emergency broadcasts are made on local ABC and commercial radio stations and Sky News television. Information can also be sought by telephone from the Victorian Bushfire Information Line. During an emergency, the Standard Emergency Warning Signal is played via television, radio and public address systems.
Current bushfire incidents and warnings are listed on the VicEmergency website launched in December 2013, Information is also available through the CFA's Twitter and Facebook sites as well as the FireReady app.
A 90-second siren at a CFA fire station indicates that CFA members are attending an emergency incident. A prolonged, 5-minute siren is targeted at the local community, indicating that there is an emergency in the area and further information should be sought.
Bushfire Management OverlaysEdit
Bushfire Management Overlays are areas identified in planning schemes within each of the Local Government Areas of Victoria that are deemed to have high fire risk. These areas are subject to particular planning and building controls.
Following the Black Saturday bushfires of 2009, interim measures were introduced by the State Government to permit vegetation removal in bushfire prone areas. The exemptions include removal of vegetation (including trees) within 10 metres of existing residences as well as all vegetation (excluding trees) within 30 metres. The measures expire on 1 March 2012.
The Victorian Government has adopted the residential building Australian Standard 3959-2009 to cover the location, design, construction of new dwellings in bushfire prone areas. The new standard includes consideration of Bushfire Attack Levels which are based on a number of factors including slope, proximity of vegetation and Fire Danger Index. New interim regulations have also been introduced for the construction of private bushfire shelters or bunkers.
Community Information GuidesEdit
The CFA, in consultation with councils and stakeholder groups, have developed Community Information Guides for locations in Victoria that are deemed to be in high risk areas. These are mailed to residents and are available on the CFA website. The guides provide emergency contact details, a map and information on preparations, planned emergency service actions and bushfire survival options. Some of these guides include designated Neighbourhood Safer Places which are sanctuaries of "last resort" during a bushfire emergency.
Common causes of bushfire, figures for Victoria over a 20-year period. Lightning is the most common cause, igniting the highest number of bushfires, which subsequently account for nearly half of the area burnt by bushfires in the state. Deliberately lit fires are the next most common, although burn much less area than fires ignited by lightning. Public utilities, such as powerlines, ignite relatively few fires, but these subsequently burn similar area to that of deliberately lit fires.
Cigarettes, matches and such, ignite a fair few fires, mostly in and around urban areas, and thus burn small areas of land as they are attended to more easily in the more accessible terrain. Many fires are caused by many other less common ignition sources or have unknown causes.
