Faustini was part of the 114 other acts who successfully got through the Arena Auditions at the SSE Arena in London that year. Together with other male contestants up to the ages of 25, he was later placed into the “Boys” category, mentored by Mel B. Faustini got through the “six-chair challenge” during bootcamp, replacing Hayden Leeman, who had initially been given a seat for his rendition of Joan Jett’s “I Love Rock ‘n’ Roll”.
