The trio have each signed multi-year deals to join the club, bringing the current total of contracted players to 13, following the recent signings of Wayne Srhoj and Simon Colosimo, and also join fellow AIS graduate and young Socceroo hopeful Kamal Ibrahim.

Head Coach John van 't Schip said the recruitment of Babalj, Taseski and Hamill marked an important step for future on-field success.

"Developing talent for the future is an important responsibility of any football club," he said.

"I really enjoy working with young players and I believe the signing of these youngsters is proof of our commitment to invest in Australia's youth.

"They have all shown an immense amount of potential in the National Youth League and for the Qantas Young Socceroos and I believe they have the perfect opportunity to build on their development."

The AIS's leading scorer in the NYL with nine goals, towering forward Babalj has fast developed a reputation as one of the brightest young striking talents in the country, impressing with his composure and clinical finishing in the final third of the park.

Taseski meanwhile earned selection for the Young Socceroos on the back of excellent performances for Altona Magic in the Victorian Premier League, where he won a Championship Medal and the Jimmy Rooney Medal for the 2009 Grand Final's Man of the Match.

The youngest player on the Heart list at 17, Hamill arrives in Melbourne after rejecting offers from English premiership outfits, with the central defender instead opting to fine tune his craft under van 't Schip and his assistants, Jesper Olsen and Ante Milicic.
