Eleven dwellings have been confirmed as destroyed in the South Coast fire, but building teams are still assessing the extent of the damage across the fireground.
The dwellings, which can also include caravans, were destroyed around the Clyde River area, west of the Princes Highway.
Fifty three sheds were destroyed in the blaze, and six dwellings and 20 sheds were partially damaged.
Building teams have assessed more than 450 properties across the fireground and a further 600 will be assessed in coming days.
The building teams are still checking areas along the coast including Bawley Point, Lake Tabourie and Termeil, which came under attack from the fire on Thursday.
Shoalhaven Rural Fire Service incident controller Ken Hall said fire crews were working to backburn critical areas around the fireground ahead of worsening conditions later in the week.
"The fire activity is predominantly in the north and north-east as well as west of the Morton National Park into Mongarlowe," Mr Hall said.
"We'll be doing more property protection to the east of the fire and hitting it with aircraft trying to slow the spread."
The fire remains at advice level and has burnt more than 78,000 hectares.
While easing conditions across the weekend allowed firefighters to carry out critical backburning, strong winds are expected to return late in the day on Monday and into Tuesday.
Fire authorities have warned of active fires still burning around Benandarah, Windywoppa, Currowan and nearby areas.
Flare ups are being forecast in unburnt areas of the fire near Lake Tabourie, Bawley Point, Kioloa, Pretty Beach, Pebbly Beach, Durras North and South Durras.
The backburning has forced the closure of the Kings Highway between Nelligen and Braidwood as the highway is being used as a containment line to the south of the fire.
Residents in Nelligen will be allowed to access the area at the discretion of emergency services.
The Princes Highway also remains closed between Batemans Baty and Burrill Lake.
After being closed off for more than a week, residents in Lake Tabourie, Bawley Point and Kioloa are being allowed access along the road to reach their homes at the discretion of emergency crews.
Mr Hall said he hoped the Princes Highway would reopen to traffic in the next 48 hours.
Araluen Road has also been closed to drivers between Moruya to Braidwood.
NSW Rural Fire Service spokesman Greg Allan said firefighters would face challenging conditions moving into Monday afternoon and Tuesday.
"We'll be seeing westerly winds tomorrow and higher temperatures before a southerly later in the afternoon," Mr Allan said.
"That could see a change in the direction for the fire which could see an elevation of fire activity.
"Residents need to realise conditions will be worse on Tuesday and if a new fire starts, it will spread quickly."
Temperatures on Tuesday will reach into the low 30s, according to the Bureau of Meteorology.
While winds along the coast aren't expected to be as strong as those seen during last week, fire crews are bracing for the worse.
Low humidity levels near the fireground are also expected to hamper efforts for fire crews.
Mr Hall said a southerly was expected to hit the fireground about 11am on Tuesday.
"That southerly will take pressure off the eastern side," he said.
"On Monday we've got a pretty strong north-easterly and a strong westerly wind hovering over the middle of the fire and it's little bit of wait and see as to what the weather will be."
