The Swedish skier, who’s in his 40’s, is seriously ill in hospital.
Paramedics say the boy was wearing a helmet, but received serious head injuries and they were unable to revive him.
The fatal accident happened on Monday in the spa town of Bada Gastein, which is popular with Scandinavia skiers.
It’s the second fatality to happen on the slopes in the Austrian Alps this month. Earlier a 44 year old Swedish woman was killed after a collision with a German skier.
