Spot fires have begun affecting parts of Bundanon Trust - but precious artworks have already been packed into fire-proof safes, CEO Debroah Ely says.
"On part of the property has seen a couple of spot fires, but the RFS put them out early this morning (January 1)," she said.
"We're very concerned, to say the least."
Staff began moving art into protective storage as early as November, with all works packed away by December 29.
Bundanon Trust has been closed to visitors for some time now, as Ms Ely said board members felt they could not guarantee visitor safety.
"Everyone is very philosophical about it - human life is most important," she said.
It will remain closed until further notice. Staff have been working closely with the RFS to ensure the property is as well-prepared for the onslaught of a fire front as possible.
"A local construction company, JBG, have put in an extra water truck for us," Ms Ely said.
"The way everyone has pulled together has been wonderful. We have been overwhelmed by community support. The staff are remarkable and have been extremely well-trained.
"Of course, in a ferocious and persistent fire, we would just have to hope."
She said her greatest concern was for the loss of historic architecture.
"The landscape we all know will recover, but to lose the cultural history would be devastating," she said.
"But everyone on the coast is at risk and the loss of homes already is devastating. It's a hairy situation for everyone.
"There are so many things that are special in this region and we are just a part of a much larger protection effort."
Some art works are in storage off site, and an exhibition of work from Bundanon Trust is currenlty safely in Sydney.
