Hrustic has one international cap after coming on as a substitute in the Socceroos' 4-0 loss to Brazil at the MCG in June 2017.
The 22-year-old, formerly of South Melbourne, had spells with Nottingham Forest, Austria Wien and Schalke before signing his first professional contract with Eredivisie outfit Groningen.
