ABC 4 Corners (Fire in the Wire, October 28, 2013) suggests cutting off electricity on hot, fire-risk days to prevent bushfires. 

173 died in 2009 Black Saturday firegrounds. 

300 died away from the fires, from heat causes. 

To cut off electricity will increase, not lessen, deaths 

Powerlines can cause fires. But deaths & house loss have been proved to be caused by poor personal preparedness & unsafe behaviour

Fire authorities acclaim The Complete Bushfire Safety Book and Essential Bushfire Safety Tips as giving the most thorough, and easily readable, information on everything you can be do to be safe.
