What do the Fire Danger Ratings Mean?

It is likely that you have seen the fire danger ratings scale, but what do the different categories mean and how can they help you to stay safe?

Understanding the fire danger rating categories, and what they mean to you, will help you make decisions about what to do if a bushfire starts.

There are 6 Fire Danger Ratings (FDR), these are based on the forecasted weather conditions and give advice about the level of bushfire threat on that day, in your local area.

  • Low/Moderate; (0 – 11) / High; (12 – 24)
    Under these conditions, if a fire does start, it is likely to be controllable, and your home can provide safety if required.
  • Very High; (25 – 49)
    These are hot, dry and possibly windy conditions. If a fire starts, it may be hard to control. If your home is well prepared it can provide safety.
  • Severe; (50 – 74)
    On severe fire day you should expect hot, dry and potentially windy conditions. If a fire starts, it may become uncontrollable. If your house is prepared and is actively defended, it can provide safety. However, if you, your house and your property are not prepared to the highest level, then leaving the high-risk bushfire area early in the day is the safest option.
  • Extreme; (75 – 99)
    Hot, dry and windy conditions are to be expected on an Extreme fire day. If a fire starts and takes hold, it will be uncontrollable, unpredictable and fast moving. Spot fires will start, move quickly and come from many directions. Leaving early is the safest option.
  • Catastrophic; (100+)
    These are the worst conditions for a fire. Homes are not constructed or designed to withstand fires under these conditions. Leaving the area, the night before, or early in the day is the safest option. Make a decision early about when you will leave, where you will go, how you will get there and when you will return.

Your Bushfire Survival Plan should take each of these ratings into consideration.
