Peter Malone has included six uncapped players in his Ireland squad for the Under-20 World Championships.
Munster pair David McCarthy and Alan Tynan are joined by Leinster trio Michael Silvester, Conor Dean and Jordan Duggan.
Angus Curtis is Ulster's lone potential debutant.
While injury has ruled out the likes of Jordan Larmour and Cillian Gallagher, Caelan Doris has been deemed fit enough to travel to Georgia.
Ireland begin their Group B campaign against Italy on May 31, before games with Scotland and the Baby Blacks.
