The RFS has urged the community to follow advice from official channels instead of listening to a scanner.
People getting information through scanners has become so prolific that the RFS in the Wingecarribee area has considered encryption to prevent the public from listening in.
The scanner is a radio network which allows firefighters to communicate with each other.
This network is made up of several different channels, which firefighters use to speak to different parts of the service.
RFS Southern Tablelands operations officer Lachlan Gilchrist said although there had been issues with people getting information through scanners, the Southern Tablelands zone was not considering encryption at the moment.
"We appreciate the community has concerns with the amount of information available," Mr Gilchrist said.
"This is deliberate so people only get accurate information, the last thing we want people to do is listen to operational conversations via radio."
Mr Gilchrist said during the last major fire people had put "themselves and their family in danger through evacuating and heading in the direction of the fire."
"People have heard [via scanner] that a fire has breached containment lines - this doesn't mean their property is in danger.
"Stick to official channels."
However, the firefighter said that no mobile service and a lack of telecommunications in some areas was "highlighted in the last major fire event".
"It's a concern that we do take on board.
"We want to make sure people are safe."
