The 42-year-old woman, named in media reports as Monika Unger, created an organisation called the Staatenbund ("Federation of States") in 2015, which counts around 2,600 members.
She had attempted to "order" the Austrian army to overthrow the government as well as asking for military assistance from Russian President Vladimir Putin.
The judge in the court in the southern city of Graz justified the heavy penalty, saying it gave a "clear signal that anti-state activities will not be tolerated".
Unger went on trial along with 13 other members of the movement who were arrested in a wave of arrests in April 2017 involving more than 450 police officers.
