Vidgen also taught himself how to play the piano and guitar. He attended Balgowlah Boys High School. Following his win on Australia's Got Talent in 2011, Vidgen withdrew from his high school to continue by distance education.

Vidgen auditioned for the fifth season of Australia's Got Talent in 2011, singing a rendition of Whitney Houston's "I Have Nothing". The performance earned a standing ovation from both the judges and the audiences. Judge Kyle Sandilands said, "You're either gonna be amazing or dreadful – both I will enjoy", while judge Brian McFadden was so moved from the performance he ran up on stage to kiss Vidgen's cheek once it was over. The performance has received more than 4.5 million views on YouTube. Vidgen was since dubbed Australia's answer to Justin Bieber and had been inundated with international and local interest. He also attracted the attention of celebrity gossip blogger Perez Hilton, who posted several blogs of Vidgen's performances on his website.
