Beaudesert farmer, Derek Shirley found six blown up cows lying dead, in a straight line after thunderstorms swept across south-east Queensland

Mr Shirley believes the cows were struck by lighting, which is what threw them against and into a wire fence.

ABC science expert Dr Karl Kruszelnicki said “the force of being pushed into the fence isn't what killed the cows” rather the electric currents which pass through the body would have resulted in simultaneous heart attacks.

Mr Shirley estimated the four cows and two calves were worth approximately $10,000.
