Firefighters say they extinguished three deliberately lit fires at Matthew Parade, Batehaven, on Thursday, September 12.
At about 2.30pm, two Batemans Bay Fire and Rescue trucks rushed to the fires located in bushland behind several homes.
Station Commander Craig Mashman said it took crews about an hour to extinguish the blazes.
"Crews were able to access three separate fires through a resident's property," he said.
Mr Mashman said Fire and Rescue confirmed the fires were deliberately lit.
He reminded the community of the seriousness of such offences.
"The deliberate lighting of fire that has the potential to destroy homes and take lives, will be dealt with severely," Mr Mashman said.
Witness statements were given to NSW Police for further investigations.
"If you see any persons lighting a fire, call Triple-Zero (000) immediately," Mr Mashman Said.
South Coast Police Inspector Angela Burnell urges anyone with information on the fire, to contact Crime Stoppers (1800 333 000) or Batemans Bay Police (44 720 099).
"Whilst the cause is not known at this point, it is extremely disappointing to consider that the fire may have been deliberately lit," she said.
"The devastation we are seeing in other areas due to bushfires is heartbreaking and worrying.
"It is beyond comprehension that anyone could do this."
