Three people have died and others remain missing following unprecedented bushfires that destroyed more than 150 homes across NSW.
A third person was confirmed dead on Saturday night after their body was discovered in a burnt-out home in the town of Johns River some 40 kilometres north of Taree on the mid-north coast.
Fires swept through the area on Saturday afternoon.
The home belongs to a 63-year-old woman although NSW Police say a post-mortem is needed to confirm the deceased's identity.
Wytaliba resident Vivian Chaplain, 69, was earlier named as one of the other victims.
Ms Chaplain was treated for burns before being transferred to a Sydney hospital where she later died, the Rural Fire Service NSW said on Saturday.
Friends have posted emotional tributes on social media.
"I am so sorry for your loss ... Vivian was such a beautiful person," Laura Hayden wrote on Facebook.
"Many condolences to all at Wytaliba, each and everyone is in our hearts," wrote Nola Mae.
It has been reported the second victim of Friday's firestorm, who was found in a burnt car near Glen Innes, is an elderly man from Wytaliba.
Seven people are still unaccounted for and RFS commissioner Shane Fitzsimmons says more fatalities are expected.
"We can't rule out the really grave concerns that there could be more losses or indeed more fatalities as we get through and identify details across these fire grounds," he told reporters in Sydney.
NSW Premier Gladys Berejiklian says her thoughts are with all those affected by the fires.
"The situation is very serious," she said in a statement.
"Our thoughts and prayers go to the families and loved ones of those who have died and to all who have been affected by these fires."
Prime Minister Scott Morrison says authorities are bracing for further bad news.
"These fires have already claimed lives ... and as we get access to further areas that have been cut off we are expecting worse news again," he told reporters at Kirribilli House.
