Vorsager made his debut for Austria U18 in September 2014 in a friendly against Norway U18. He scored his first goal in May 2015 with the winning goal in a 1–0 victory against rivals Germany. In May 2016, he made his debut for the national under-19 team. He was then called up to the squad for the 2016 UEFA European Under-19 Championship. His only appearance was in the last group game against Germany, when he was in the starting eleven and was replaced by Sandi Lovrić at half-time. After that, Austria were eliminated as bottom of the group.

In addition to his career as a football player, Vorsager has also been active as a model under the stage name Sascha Wolf.
