Nicholson was born in Hobart and grew up in Melbourne, attending St Kevin's College in Melbourne. Before he became a member of Hi-5, he had worked at Brainstorm Productions on a show called Verbal Combat.

He has revealed that his childhood was marred by a serious illness, bacterial meningitis, before he discovered acting in his teenage years.^[1] Children's entertainment programmes such as Playschool were key to his recovery, which explains his continued passion for the industry.^[2]

He has completed an Arts degree at Deakin University.

Nicholson joined the Australian children's musical group Hi-5 in June 2007 when original member Tim Harding was injured in a serious motorcycle accident.^[3][4] Nicholson was hired as an understudy just a few days prior to this, and immediately took on Harding's touring responsibilities.^[1] In November, Harding announced his permanent departure from the group after recovering from his injuries, with Nicholson taking his place as a permanent member^[4][5] Creator of the franchise Helena Harris stated, "it's like [he] was born to this job."^[1]

Nicholson filmed seven television seasons of Hi-5 and Hi-5 House, before announcing in August 2015 that he would be departing the group at the end of the year.^[2] He revealed intentions to further his performing career and author a children's book entitled Superdudes.^[2] Of his time with Hi-5, he stated, "it has been an absolute whirlwind journey", and expressed that he had learned more from children than he had been able to teach.^[2][6] His final performance was on tour with the group in December. His replacement was Lachie Dearing.^[7] He returned to the group as a guest performer in December 2018 and November 2019.

After Superdudes was released in October 2015, Nicholson transferred the work to the stage with a tour featuring characters from the book.^[8][9] The tour experienced an overwhelmingly positive response in the Philippines in 2016.^[10] The group toured regionally across Singapore, Hong Kong and Indonesia in 2019.^[11]
