The NSW Rural Fire Service has spent the night containing blazes in smouldering bushland ahead of strong winds and warm weather with a number of them still burning out of control.
Dozens of fires, fanned by strong winds, warm weather and dry tinder, have raged across the state over the weekend.
Fire crews worked to contain major fires near Lennox Head and Salt Ash, north of Newcastle, but both broke containment lines before the RFS managed to bring them under control as night fell on Sunday.
Meanwhile a fire in the vicinity of Old Glen Innes Road, Buccarumbi, 30km southwest of Grafton, is burning out control. It has already razed 474 hectares and is threatening a small number of isolated properties.
Warn strong winds are forecast to continue until Wednesday, with fears the blazes will flare up and threaten homes again.
Nearly 20 buildings, mostly outbuildings, have been destroyed by fires since late last week.
In that time, two people were charged with lighting fires in the north of the state while helicopter pilot Allan Tull died while conducting aerial water-bombing on a blaze near Ulladulla.
