You're safe here yeah....

A Perth man has filmed the moment he was struck by lightning while watching a thunderstorm in his backyard.

Russell Southey, assured his wife "you're safe here" as he made a video of lightning striking around his Baldavis home in the early hours of Friday morning, the Daily Telegraph reports.

The footage shows several massive strikes before he is suddenly thrown to the ground, screaming obscenities.

"It was just like a big jolt, I didn't know what it was," Mr Southey told Sky News.

"It was as if something had hit me in the side and thrown me on the ground at the same time."

The lightning knocked him 1.5m backwards to the ground. He was taken to Rockingham Hospital but was released a few hours later.

Mr Southey said he still had no feeling in some of his fingers and his shoulder was very sore.

Lightning strikes kill between five to ten Australians every year and injure over 100, the Bureau of Meteorology says.
