But he told KIIS FM that he regrets appearing on the Channel Seven series last year and won't be judging again on TV anytime soon.
"I wouldn't do any TV for the near future, just because I decided that last year and they came to me and said, 'Do X Factor, it's only five weeks, it's a very short stint'," Sebastian said.
"So I did it and I can't say I was in it, I didn't feel like I was in it."
Channel Seven confirmed in January that X Factor won't be returning this year after disappointing ratings in 2016 when the judges were Guy Sebastian, Iggy Azalea, Mel B and Adam Lambert.
"I feel like it's good that it's going on a break," Sebastian told KIIS FM.
"I think we just need to let talent ... mature a little bit, we need to let the pool of talent develop. I think everything has its time and we're so saturated with all of this stuff and it's probably a good time for it to be rested."
