The 26-year old Croatian has put pen to a brand new two-year contract with the Sky Blues after joining the club from Sydney United in June 2012.
"I'm extremely happy to be staying at Sydney FC for another two years," he said. "It's a great environment to learn in and I feel I have come a long way in my development already.
"The coaching staff and all of the guys in the dressing room have been fantastic since I joined the club and I'm delighted that I will get the chance to improve here."
