A man struck by lightning on Eyre Peninsula is recovering in the Royal Adelaide Hospital.
The man, 26, was hit while working on top of a grain bunker at Rudall on Tuesday morning.
He was taken to hospital at Cleve and later flown to Adelaide, where his condition now is stable.
Lorraine Amos of the SA Ambulance Service says the man had injuries caused by lightning having passed through his body.
"It did make the patient unconscious for a short period of time but on arrival of our first crew he was already standing up and walking around although clearly distraught by the pain he was in," she said.
The grain bunker is owned by Viterra, which has shut down the site while the matter is investigated.
There were more than 66,000 lightning strikes recorded across South Australia in the past day.
Some of them sparked grass fires.
