"When the power went out we heard three big surges and then flashes, then we saw the fire," Mrs Peter's said. 

"All of the grass around the front of the Caltex was on fire. 

Keen to investigate if they could be of assistance Mrs Peters and husband Jake an electrician spotted downed lines near the scene. 

"It was too dark for anyone to see, truckies got out of their trucks to help direct traffic around the fire before anyone arrived," Mrs Peters explained. 

"The fire trucks pulled up and then Ergon arrived, we pointed out the lines. 

"The power does go out all the time but it had never caught fire before," she said.
