Accepted into NIDA straight out of high school, Nicholas knew he wanted to act from a young age, when he was practising monologues on the soccer field instead of helping his team win. He has trained at iO West, The Second City and Atlantic Theater Company in Los Angeles.

Nicholas was the lead in Australian feature film DAMAGED, shot from 2012-2016, and recently starred in the short film JACK-RABBIT (Dir. Alex Feggans), which entered into both Cannes and Venice Film Festivals.

Nicholas is passionate about creating his own content. He and best friend Matt Castley have created a youth drama series NAKED shooting in 2019 (Dir. Elissa Down). Nicholas also recently released a comedy web series DAVE & THEO, which he wrote, co-directed and starred in alongside Laurence Boxhall. The series, selected into nine elite international festivals, is trending across social media platforms.

Nicholas is currently the voice of Nutrigrain commercials.
