In page Austrian German:

"

In Austria, as in the German-speaking parts of Switzerland and in southern Germany, verbs that express a state tend to use sein as the auxiliary verb in the perfect, as well as verbs of movement. Verbs which fall into this category include sitzen (to sit), liegen (to lie) and, in parts of Styria and Carinthia, schlafen (to sleep). Therefore, the perfect of these verbs would be ich bin gesessen, ich bin gelegen and ich bin geschlafen, respectively.[citation needed]
