Dino Djulbic was, along with Andreas Oliveira and Antonio Naglieri, one of three Western Australian players controversially signed by South from Frankston Pines during the 2006 mid season transfer window. He was also by far the most successful of the three in securing a professional career after his South stint. A defender, Djulbic was crucial to South's title run, especially his outstanding efforts in the grand final. After impressing at a trial with Perth Glory during 2006, Djulbic was signed by them, but not before playing eleven matches for the club in the early part of 2007.
In 2012, Djulbic made two appearances for the Socceroos (against Guam and Taiwan), during qualifying for the 2013 East Asian Cup.
