From the article-
"As our photographs show one of the worst hit areas was the beautiful “Fairy Glen”, while nearby a stone building at Rockfield Park was lifted from its foundations. According to first hand reports some trees were thrown by the force of the wind up to 50 metres from where they had been rooted, but no loss of stock or serious injuries resulted. The road between Berry and Kangaroo Valley was closed for several hours while emergency service and KVRFS crews cleared fallen trees and power lines."
