The State Mine fire at Lithgow was one of the biggest blazes that have been ravaging New South Wales since last Thursday.
A Rural Fire Service investigation has confirmed it was started by a live-fire military exercise.
It has claimed three homes, though crews have it under control. It is currently on watch-and-act status.
