Cooler conditions have brought a welcome relief from bushfires but farmers near Yass in southern New South Wales are now having to deal with livestock losses.
A large bushfire that burned to within 11 kilometres of Yass has now been brought under control.
No homes were lost but thousands of sheep were unable to escape the blaze which burned 14,000 hectares.
Hundreds of sheep were killed by the fire. Many that survived have burnt faces and feet and farmers have been forced to shoot and bury the animals.
If the sheep are not euthanased they will die a slow and painful death from their burns.
It is estimated more than 10,000 animals have been lost in the fires, with about 3,000 sheep destroyed near Yass today.
Yass farmer Louise Armour says a thousand sheep were killed or injured on her property.
"Even now when I think about assisting those lambs into the pens, ready to be put down, we love our animals dearly," she said.
"You want to do the best for them at all times and that was the best I could do, just gently usher them into the pen."
Yass farmer Doug Painting says fodder drops are being made for surviving livestock.
"It's a very tight knit community. People are running on adrenalin at the moment and overwhelmed by the support that's come in. People will need some time out in the next few days that's for sure," he said.
Fire crews are still working to control a blaze at Kybeyan Valley in southern NSW which has burned 9,400 hectares.
The firefront is now about 20 kilometres east of Cooma and crews are working to build containment lines.
A blaze that burnt out about 1,400 hectares near Bungendore is now contained.
The Kings Highway between Bungendore and Braidwood re-opened late this morning.
Temperatures across much of New South Wales are set to top 40 degrees Celsius again on Friday.
NSW Rural Fire Service Chief Fire Officer Alan Goodwin says crews are racing against time to contain the fires.
"These milder conditions are certainly giving us a little bit of breathing space," he said.
There are no fires in the ACT but smoke is being blown into the Territory from bushfires in the Shoalhaven region.
