A 90-year-old man has died in hospital after suffering critical injuries in a house fire at Sunshine Bay.
Emergency services were called to a home at Bronte Crescent, Sunshine Bay, about 7.45pm on Sunday, August 18.
Police found a man inside the home suffering smoke inhalation and burns after the mattress he was sleeping on had caught alight.
The man was treated at the scene before being taken to Batemans Bay Hospital where he was listed as critical.
He was unable to recover from his injuries and died in the early hours of Monday morning, August 19.
Batemans Bay Fire and Rescue station commander Craig Mashman said the cause of the fire was unknown and investigations were continuing.
Mr Mashman urged residents to be vigilant when using heaters and electrical appliances.
"There is another cold front coming through," he said.
"If you have a heater on, Fire and Rescue recommends you keep all materials one metre from the heater."
UPDATE: Police later reported the fire was understood to have ignited from a hot wheat pack.
