Authorities gave no immediate details on the condition of the other casualties in the incident, which occurred around midday in a valley south of Innsbruck in western Austria.
Saturday also saw a number of other avalanches -- the result of instability caused by recent snowfall and a slight thaw -- in which skiers had to be rescued in Austria's Tyrol state, famed for its ski resorts and winter sports.
The deaths follow a string of deadly snowslides in the French Alps this season.
Two French teenage students and a Ukrainian tourist were also killed on January 14 when a teacher took the students onto a closed skiing piste at the Deux-Alpes resort. Seriously injured himself, he was later charged with involuntary manslaughter.
