The Australian military is investigating whether it was responsible for starting major bushfires that have destroyed up to 300 homes.
Around 85 fires are still burning across New South Wales - with 20 still uncontained.
The blazes have so far burned through around 30 thousand hectares of land.
The Australian Defence Force says it was carrying out explosive ordnance training in the area, the day the fire started.
They're now investigating if the two events are linked.
