The bushfire danger period will start early this year due to ongoing warm and dry conditions.
While the bushfire season traditionally starts on October 1 each year, the Southern Highlands will begin on September 1.
NSW RFS district manager superintendent Martin Surrey has urged residents to now the risks and take precautions now.
"We have experienced a long dry and warm spell, which is increasing the bushfire danger across the region," Mr Surrey said.
"There are simple things you can do now to get ready for bushfire season - such as talking with your family about your bushfire survival plan, preparing your home or property, knowing the bushfire alert levels and making sure you know where to get information during a fire.
"The things you do now can make a big difference to your safety during a fire, and whether your home survives."
Landholders are also encouraged to use fire safely if conducting hazard reduction activities.
"Many people use fire to reduce the fire risk on their property - but if fire's not used properly, you can end up being the fire risk to your community," Mr Surrey said.
"Permits are required during the bushfire danger period. They're free and easy to get by contacting your Fire Control Centre.
"Don't be the risk to your community. Use fire safely and only light up if conditions are safe.
""Never leave a fire unattended and if a fire does escape, it is essential to call triple zero (000) immediately so that emergency services can respond accordingly and minimise the damage."
