Bushfires are threatening a caravan park and a number of properties across NSW after hazard reduction burns on private properties escaped control.
At least 10 bushfires have kicked up on Sunday and are burning out of control under warm and windy spring conditions.
A bushfire southeast of Mogo, on the NSW south coast, is threatening a caravan park at Tomakin.
Twelve crews from the NSW Rural Fire Service (RFS) are battling the blaze, RFS spokeswoman Rebel Talbert said.
In the NSW Hunter region another fire has scorched about 10ha and is threatening a number of properties near Marsh Road, at Bobs Farm, in the Port Stephens area.
In the NSW far southeast, a fire in the Eurobodalla area, west of Central Tilba, has been burning since late August and broke containment lines on Sunday and is approaching a property.
"We're seeing very erratic fire conditions," Ms Talbert told AAP.
"Crews are unable to protect that property - it's too dangerous to have them in there."
Changeable weather conditions and difficult terrain have stifled ground efforts, Ms Talbert said, but water-bombing aircraft are battling the blaze to slow down the bushfire's approach to the property.
Two other bushfires in the Eurobodalla area ignited on Sunday and are burning out of control at Belimbla, near the Dampier State Forest, and at Courier Creek.
The RFS is working to determine the nature of the fires and if any properties are under threat.
"A lot of them are escaped private hazard reduction burns and look like they have spread," Ms Talbert said.
The RFS has declared a total fire ban across Sydney, the Central Coast, the Blue Mountains and the Central West including the towns of Dubbo and Parkes.
The ban comes after the Bureau of Meteorology advised initial forecasts of hot, dry and windy conditions are expected to worsen and cause an extreme fire danger across many parts of the state.
Another six fires have kicked up in the Lake Macquarie area, near Newcastle, and are burning out of control.
Firefighters are focusing their efforts on a blaze at Killingworth, north of Morisset, with six trucks and 40 firefighters on the ground.
