He first received media attention in Australia when he was 10 years old when he won a football talent competition on Channel 7 television show, Today Tonight, winning a trip to Madrid to make a training skills DVD with David Beckham. Frank Farina, former Socceroos coach and judge of the Channel 7 competition said: "His juggling is very good, he pulled out a squash ball and started juggling that and didn't drop it once, he is very impressive." He also obtained a sponsorship from Adidas because of his exceptional juggling skills.

Speculation and trials
After signing with Sydney FC, he was linked with possible moves to Everton, Inter Milan and Marseille.

In February 2012, Antonis reiterated his commitment to Sydney FC and the remainder of his three-year contract, stating that he is more than happy being at the club.
At the conclusion of the 2012-13 season, Antonis was approached by Dutch club FC Utrecht for a trial only for Sydney FC to accept bid from Italian Serie A club, Parma. He signed a four-year deal after Parma triggered a release clause in his two-year deal. The deal never went through and Antonis to Sydney FC.
