Australia's Got Talent Winner Gets 2nd Chance
"It's a dream come true," the 37 year-old singer admits. "It's still sinking in to tell you the truth."
Performing an original song called "Now That I Believe"in the grand final, the song is all about keeping his faith during his dark times.
De Silva gained popularity in CDB with their debut single "Hook Me Up" and the album Glide With Me, but it was their cover of "Let's Groove" that thrust them to the top of the charts.
However, De Silva was diagnosed with cancer at 22 and had to quit the band following their second album, Lifted.
Additionally, he had a severe stutter going into the competition, but took an intensive course to help overcome his condition and even considered pulling out of the comp at one point.
Luckily, he stuck with it and judge Brian McFadden believed in the singer from the moment he stepped out onto the AGT stage at the start of the series, saying at the time he felt De Silva would win.
"When somebody says that you think 'Oh no is it a jinx?' I don't want to hear that, I don't need to hear that now," he laughs.
Winning the grand prize of $250,000 will help take care of his wife and two kids and relaunch his music career, with his eyes on securing a record deal.
"Yeah, well there's talk of that," he says about a deal. "We'll be chatting (to Sony Music) today. That's the dream to get an album out there really soon and start doing the gigs again and get my music out there."
