Fran Morgan, who lives next door to the area on fire, said she was concerned it would spread to her property.

"We were sitting in the sun and saw the flames behind the trees. We were worried it was going to spread to our property.

"I believe it was a controlled burn off, but the wind got up, that was his problem."
