When he graduated high school he began teaching vocals to schoolchildren and working as a sound engineer.
But it was his decision to enter a reality TV show singing contest in 2003 that would change the course of his life.
Guy Sebastian's mother would later tell media the family had no idea how big Australian Idol would turn out to be when he entered.
He became the show's first winner, and arguably its most successful alumnus.
Since then, the soul artist has performed across the country, and across the globe.
He's picked up four ARIA awards, and has been nominated for 23.
Sebastian is also a family man, marrying the love of his life, Jules, in 2008. They have two children, Hudson and Archer.
