With Irish heritage in his family, Jack was to follow in the footsteps of his older brother in lining out for the Irish Exiles (the purpose of the Exiles Branch is to identify and develop potential Irish professional players in England, Scotland and Wales) and winning selection for Ireland U18 Clubs. Impressive representative performances at that level, under the stewardship of Munster Elite Player Development Officer Colm McMahon, placed him firmly on the radar of the Greencore Munster Academy.
At the start of the 2013/14 season Cullen accepted the offer to join the Academy ranks, making the move from the Saracens youth programme. Since then, the scum-half represented Munster U19s in last season's interprovincial series, and played for Ireland U19s against Australia Schools at Ravenhill last December.
At just 18 years of age, he came off the bench in three of Ireland U20s' games of the 2014 Six Nations, making his first start against France.
Jack speaks about his time in the Academy to date. "Wherever you go there's a different style of play and I've certainly learnt a lot from the people I've played with so far in my career. The way the game is played here is differs from the way I played in England and playing both styles has helped vary my game and in particular has helped my game management.
"Getting to train with the senior players in Munster, where it's a case of faster pace and greater accuracy, has been massively beneficial to us in the Academy.
"Also the whole experience of moving out of home, away from my family in England, together with the discipline of becoming a professional rugby player has developed me as a person, I've grown up fast over the past year!"
