The crew will replace the fire fighting team Victoria sent last week and will begin work from Tuesday to Thursday helping the NSW effort.

The contingent includes 100 Country Fire Authority (CFA) fire fighters and 20 incident management experts from the Metropolitan Fire Brigade (MFB), CFA, Department of Environment and Primary Industries and Parks Victoria.

Mr Lapsley says NSW authorities will inform Victoria on Monday whether further assistance is needed.

"This week in NSW there's a critical couple of days," he said.

The contingent of Victorian crews has been drawn from northern and central Victoria.

South Australia sent a crew of 51 and Tasmania a team of 20 staff.

A Tasmania Fire Service spokesman said crews would be deployed for six days until Thursday, but could not comment on whether further crews would be replaced.

A SA Metropolitan Fire Service spokesman said a request had been received from NSW for more troops and it would send another six replacing 12 coming home on Tuesday.

He said he was unable to comment on the team of 40 from the SA Country Fire Service, who could not be contacted. AAP

People in Bell are being told to leave the small Blue Mountains township, while others are warned they may be isolated for days as a large bushfire burns in the region.

The fire, which has scorched almost 38,000 hectares of bush and scrub, sparked Sunday afternoon's call for all unprepared residents to leave their homes and to head to Lithgow.

Those in the nearby village of Bilpin, as well as the communities of Mt Tomah and Berambing, are also being advised to relocate immediately to Richmond.

Those locals between Mountain Lagoon Road and Bowens Creek Road in Bilpin Village who wish to stay have been warned that they may become isolated.

The Rural Fire Service (RFS) have told residents that their properties need to be properly prepared because electricity to the area may be cut off for several days.

Meanwhile, people in Mt Irvine and Mt Wilson, just west of Bilpin, are being told to stay in place since there is fire burning along access roads.

These residents are also being told to prepare for a number of days of isolation.

The RFS advised people to try and stay with family and friends if possible, but evacuation centres have been set up in Richmond and Lithgow for when that is not an option.

For people living along Bells Line of Road, which runs along the region, the Department of Primary Industry said they can temporarily relocate their pets and livestock to the Hawkesbury Show Ground in Clarendon or to Lithgow Workers Club.

Animals should be brought along with their cages, food and medication, where required. AAP

Sandra Kay approached Mr O'Farrell as he visited fire ravaged areas in Wyong on Saturday.

"Excuse me Mr O'Farrell, I almost died on Thursday night, the reason being National Parks and Wildlife does not do perimeter burning on their property," the middle-aged Crangan Bay resident said.

"My house has been threatened twice in the last ten years from the south mainly because National Parks and Wildlife is not doing their job."

Mr O'Farrell replied that a "huge amount" of backburning had been carried out in the area but said he would take her concerns to the local council and to parliament.

October 19: 10.35am:
The Defence department has launched an investigation into the State Mine bushfire that started on Wednesday.

Mr O'Farrell is being given a rundown by Rural Fire Service (RFS) Commissioner Shane Fitzsimmons at the Wyong command centre and will later brief the media and visit residents. The Wyong fire has burnt more than 2500 hectares, damaged historic buildings in Catherine Hill Bay and caused the death of a 63-year-old man who suffered a heart attack defending his home in Munmorah. The fire has been downgraded from an emergency warning to a watch and act and is being controlled, the RFS said.

October 18: 7:15pm:
Residents who escaped the oncoming blaze have described flames and thick plumes of black smoke surrounding them as they tried to evacuate.

Blue Mountains resident Catherine Hubbard told AAP she had been sleeping as the fire crept towards her house.

A phone call from a worried colleague alerted her to the danger.

"I hung up and said 'I'll be fine'," she said.

"But when I went out and checked outside my veranda there was a tree alight and fire all around the backyard."

She ran to strangers on the street and asked if she could take shelter at their home.

"The sun was totally blocked out and houses were burning down to the ground all around us," she said.

With no running water they used buckets and wet towels to douse embers around the house.

A sudden change in the wind cleared a path in the smoke and Ms Hubbard was able to move to safety.

When she returned home on Friday she found her house destroyed by the fire. She says she will take her children back to their old home on Saturday "to give them closure".

"This will be a fresh start for us," Ms Hubbard said.

"We're a pretty resilient family."

October 18: 6:50pm:
RFS Commissioner Shane Fitzsimmons is asking residents to remain vigilant as fires continue to burn across NSW, ABC reports.

"We've got six fires still at watch-and-act level, and that's because fire is still very active in and around these fire grounds and as we saw today, circumstances can change," Mr Fitzsimmons says. "A fire can flare up and run up a valley system, it can get a breath of wind behind it and fan the flames forward.

"That's why they're at watch and act. People need to be remaining vigilant."

Mr Fitzsimmmons says a reprieve is expected tomorrow before a frontal system moves across the state.

"Our main concern is we've only got a small window of opportunity, principally tomorrow, before we see the onset of another frontal system that's going to move across NSW.

"Now while we're not expecting it to be quite what we saw yesterday obviously, but we are expecting to see temperatures rise back into the 30s, very low humidities with a north-westerly influence coming across a large tract of NSW, albeit that those winds are not expected to be anywhere near the strength we saw the other day."
