An additional 21 areas across NSW will enter the bushfire season in spring with the Rural Fire Service warning recent rain has increased the threat of grass fires in coming months.

NSW Commissioner Rob Rogers said those local government areas would start the Bush Fire Danger Period from Wednesday, September 1, bringing the number of LGAs in bush fire season to 27.

“Over coming weeks and months, grass fires will be of particular concern, especially in these areas that have entered the bush fire danger period,” Commissioner Rogers said on Tuesday.

“Landholders and firefighters have reported increased grass growth from recent rain, particularly west of the ranges.

“The threat of grass fires will increase as this dries out.”

The remaining areas of NSW are expected to start their Bush Fire Danger Period in October.

Anyone wanting to light a fire during the danger period must obtain a permit and notifying their local fire authority and neighbours 24 hours before lighting up.

“While hazard reductions are an important part of preparations, landholders need to be extremely careful, as escaped burns can lead to heavy penalties,” Commissioner Rogers said.

“Now is the time to update and discuss your bushfire survival plan.

“Have the conversation with your family about what you will do during a fire – talk about when you’ll leave, where you’ll go, what you’ll take and what you’ll do with animals.”
