UPDATE SATURDAY 9AM: FOUR rural fire crews are on scene of a bushfire at Fernvale this morning.

Fire fighters are monitoring containment lines however the blaze is under control.

EARLIER: FIREFIGHTERS are likely to remain at the scene of a massive bushfire at Fernvale until at least Sunday.

A huge effort from more than 40 firefighters, combined with aerial water bombing, kept the 390 hectare blaze from threatening local residents, who were on alert today.

Rural Fire regional manager Alan Gillespie says he is still not prepared to declare the fire under control, however the worst of the threat had passed.

"We've had a few minor spot fires over our containment lines, but that was to be expected with the wind and we were able to eliminate those quickly," he said.

"The fire is not posing a risk to properties and we are bringing it under control.

"The major areas of concern are along England Creek Rd but I'm highly confident of preventing the spread of the fire to that area."

The fire is burning in a largely inaccessible area of scrub south of Wivenhoe Dam.

Firefighters are likely to significantly scale back the number of troops on the ground this evening, leaving local crews to keep an eye on the blaze into the weekend.

It is hoped that rain forecast for Sunday will bring the effort to a conclusion.

EARLIER: A STRIKE team of firefighters is being called in as a large scale bushfire continues to burn near Fernvale.

The fire started about noon on Thursday and has quickly spread across hundreds of hectares of rugged country south of Wivenhoe Dam.

Rural Fire regional manager Alan Gillespie says the fire continues to burn freely along the western sector near England Creek Rd, not far from more than a dozen properties.

"This fire is not contained and we've got 13 properties in that area," he said.

"We've been door knocking this morning to keep people up to date.

"Our containment strategy went well overnight and we will spend today back-burning to protect those houses on England Creek Rd.

A strike team from the Gold Coast will also be arriving today to conduct mapping.

There are 16 fire crews on the ground - comprising of about 40 personnel - with more to be deployed during the day.

Superintendent Gillespie said the change in wind direction overnight was expected and worked in the favour of firefighters, who were desperate to keep the fire from spreading towards Mt Nebo.

He said today's weather should also work in favour of the effort to control the blaze.

"We are happy we'll be able to hold it today," he said.
