Harrison is best known to television audiences as the slack-jawed Oscar Bright on ABC’s Upper Middle Bogan, for which he received a 2014 Logie nomination in the category of Most Popular New Talent. He received his first taste of performance for TV by accident when he was ‘pranked’ by his best friend on the popular children’s comedy Prank Patrol and from there has thrown himself into the world of comedy and acting with passion and enthusiasm, recently attracting the interest of major US-based management.
