The blaze began as a small rubbish fire that quickly got out of control, in a rural area with kikuyu grass, wilding pines and forestry slash.
"It was a local who is relatively new to the area who's just bought a section out there who just thought that he would light a small fire and burn a bit of rubbish," Bristow said.
"All the conditions were just not in his favour so we're stressing that exceptional care needs to be taken when lighting a fire."
