Monastery secretary Kim McSweeney said the sanctuary's monks and animals relocated to her house in Moss Vale ahead of Saturday night's Morton Fire.

"The monks are all safe as well as our peacocks and cat. We didn't want to risk any lives," she said.

"The monastery was as prepared and secured as it could be.

"If we have to work to do, we're prepared for that."

Prior to their relocation, the monks put out plenty of water and food for bushfire-affected wildlife.

In a statement on its website, the Sunnataram Forest Monastery team expressed its gratitude to Rural Fire Service and Fire and Rescue crews.

"We are very grateful to all selfless firefighters who have been working very hard to save many lives and properties," the statement said.

"Our condolences to families and friends who lost their members and properties.

"May the Buddha's blessings be with you and all of us.

"We wish all of us for a very peaceful New Year 2020. May all of us achieve the highest wisdom and free ourselves from unhappiness in the present life."

Ms McSweeney said monks from the Santi Forest Monastery and the Vejjasala Monastery also relocated ahead of the fires.

She said she was unsure of the condition of the two monasteries.

Sunnataram Forest Monastery will be closed to the public until further notice due to the threat of bushfires in the Southern Highlands.
