NSW RFS firefighters have brought a blaze burning north east of St Georges Basin off The Wool Road under control.

The fire, which started near The Wool Road on Monday afternoon, has burnt approximately 60 hectares of bushland, with crews currently undertaking the latest mapping to determine the blaze’s size.

The fire was burning in a northeasterly direction, with crews undertaking backburning operations overnight to bring the blaze under control.

Rain predicted of the Shoalhaven arrived on the fireground early Wednesday morning and has proved more of a hindrance than a help for firefighters.

While conditions on the fireground are reported to be very benign, with high humidity and no wind, the area is quite damp, hampering any proposed backburning operations for this morning.

A bulldozer is currently being used to put in containment lines from the west to the east to secure the fire’s eastern containment. Similar operations will also be undertaken on the northern containment.

Several crews with 37 personnel are still on the ground ensuring the fire is secured. Test burns will also be staged to ascertain options regarding any possible backburning.

There are no threats to any properties, with the predicted weather conditions looking favourable.

Update at 3.30pm

NSW RFS firefighters are preparing for a long night on the job at St Georges Basin.

The fire, which started near The Wool Road on Monday afternoon, has spread across 50-60 hectares of bushland.

RFS Shoalhaven spokesman Brad Collins said five fire crews, including about 20 firefighters, will continue back burning operations in the area.

“Our work on the patch on the western boundary went well,” Mr Collins said.

“Our concern into the evening is containment around eastern and north-eastern ends.

“Unfortunately for nearby residents we’re going to have to undertake more back burning, pushing up more smoke into the night.

“We’ll be working through the evening and most of the day tomorrow.”

Mr Collins estimated once the fire is controlled, it will have burned through more than 100 hectares.

He said the RFS has been mindful of fatigue management, and ensured the South Coast Register volunteers will do the work in shifts.

Update at 12.45pm

The NSW Rural Fire Service has asked residents and visitors to the area near the St Georges Basin fire to avoid the area if they do not need to travel along The Wool Road.

The RFS has dispatched crews to manage a flare-up near the main arterial road connecting Sanctuary Point and St Georges Basin residents to the Princes Hwy.

“There will continue to be a lot of smoke in and around The Wool Road area,” Shoalhaven RFS spokesman Brad Collins said.

“Motorists may need to slow to 40km per hour if there are fire crews on scene.”

No property has been under threat.

Five RFS crews including 20 firefighters have been working to contain the blaze.

“We’re still trying to contain the fire,” Mr Collins said.

“Parts of the fire are still inaccessible.

“We are doing back-burning on the western boundary of the treatment works, from the back of the (St Georges Basin) fire station to the edge of fire. We want to take that block out.”

Meanwhile, three RFS crews who were called to investigate smoke west of Tomerong have found a car alight in the bush.

The fire had spread into the bush covering a 100m by 200m area near the Parma Firetrail, east of Parma Creek.

Fire crews have extinguished the blaze, and were mopping up at 12.45pm.

Police attended the fire and will make further inquiries.

Update at 11.20am

The fire burning in St Georges Basin bushland is visible from The Wool Road.

The road connecting Sanctuary Point and St Georges Basin residents to the Princes Highway was open, and motorists were able to travel in both directions.

A Fairfax Media journalist has captured footage of the scrub fire from the Wool Road, standing between Chessell Lane and The Wool Lane turnoff.

Moderate northeasterly winds are forecast to pick up in the afternoon, and drop slightly at sundown.

Plumes of smoke from the fire have been reaching surrounding towns and villages.

NSW Rural Fire Service crews have been working to contain the fire, which had burned through 44 hectares of bushland by 7.32am on Tuesday.
