Devastating bushfires are ripping through parts of Northern New South Wales and South East Queensland, leaving three people dead and scores injured.

More than 150 homes have been destroyed.

A man was discovered inside a burnt out car this morning at the Kangawalla fire, near Glen Innes in NSW, while a woman died in hospital after being found overnight with severe burns.

It is though the man was trying to escape the ferocious fire.

Police are yet to identify the two.

The NSW Rural Fire Service (RFS) commissioner Shane Fitzsimmons said the now deceased woman had "40-50 per cent burns to her body", according to The Daily Telegraph.

NSW Premier Gladys Berejiklian told reporters the carnage had escalated with seven people now reported missing. More than 1300 firefighters and volunteers continue to battle blazes across the state.

"The situation is beyond serious. Our thoughts and prayers go to the families and loved ones of those two deceased persons," the Premier said.

"We are seeing situations in NSW with these fires we have not seen before and of course concerns remain mainly around the Glen Innes area and also Port Macquarie and Taree regions and the townships around those communities."

The RFS' Mr Fitzsimmons has warned that the death toll is likely to rise beyond two.

Seven people are said to be missing.

"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.

Prime Minister Scott Morrison said army reservists could be deployed "if necessary". While they aren't trained firefighters they could help create firebreaks away from the front or provide accommodation and logistical support, Mr Morrison said, reported AAP.

"These fires have already claimed two lives … and as we get access to further areas that have been cut off we are expecting worse news again," he said.
