"I do have some 72 fires around the state at the moment, five of those are of concern and we are keeping an eye on those and obviously planning on dealing with those."

The rural firefighter reinforcements from across the border arrived in Brisbane overnight for a briefing before travelling to Gladstone on Tuesday morning to be deployed to the front lines in Agnes Water to relieve local crews.

NSW Emergency Services Minister Troy Grant said relief was in sight for Queensland firefighters.

"The NSW RFS crews deployed last night will work with fellow Queensland rural firefighters and provide relief for local crews who have worked very hard over the last week.

"Fifty volunteers flew out of Sydney yesterday, while another 50 travelled by coach from Northern NSW, and arrived in Brisbane last night for a briefing before being deployed to various parts of Queensland affected by the current fires.

"Along with our force of 100 firefighters, the NSW RFS has also deployed Gaia, the Boeing 737 Large Air Tanker, as well as the lead plane ‘Bird Dog’, to assist Queensland."

Queensland Premier Annastacia Palaszczuk told ABC Radio Brisbane on Tuesday that crews on the ground were "stretched".

"There is so much happening across Queensland at the moment but the major point of concern is around Deepwater National Park," she said.

"These are unprecedented conditions ... we are seeing temperatures six to 10 degrees above average at the moment."

Residents in Deepwater, Baffle Creek, Rules Beach and Oyster Creek have been told to evacuate, while Round Hill locals should prepare to leave their homes.

Firefighters have been working around the clock to control the wall of fire and have pleaded with residents to abandon their homes and move to safer ground.

Dave Brereton and his partner Miki "bolted" from their home, which backs onto Deepwater National Park, on Monday morning.

"When we woke up, we were just covered in smoke and it was really hard to breathe," he said.

"There was a lot of billowing smoke just a few kilometres from us and it was very, very red.

"We just got everything out because we thought it was the smart thing to do.

"We are back home now, our side of the hill did not get touched which was fantastic – but we are not out of the woods yet. We are all packed up and ready to bolt again at any moment."

A disaster zone was declared for parts of the central Queensland coast on Monday afternoon, by Fire and Emergency Services Minister Craig Crawford.

The disaster declaration covered the Gladstone local government area, incorporating the Baffle Creek Catchment, Wartburg, Deepwater, Agnes Water, Round Hill, Miriam Vale and Bororen.

The blaze ignited in Round Hill on Thursday afternoon before splitting into two uncontrollable fires by Saturday.

Hundreds of homes remain at risk and two have already been destroyed.
