Guy Sebastian shares for the first time why he thinks the X-Factor Australia ratings flopped.

X-Factor judge Guy Sebastian has wasted no time rubbishing the format of this year’s X-Factor season just days after the finale was aired.

After the reality television show failed to capture attention of Australian viewers, documenting some of its lowest ratings in is eight season history, Sebastian has said a multitude of factors resulted in the disappointing reception this season received.

Last week’s X-Factor finale, taken out by young indigenous singer Isaiah Firebrace, finished third in its timeslot with a viewership of 751,000, behind ABC’s 7.30 and Australian Story according to TV Tonight.

Talking to the Daily Telegraph, Sebastian was honest about the fact X-Factor did not deliver what was expected in 2016.

“The ratings were a huge struggle, but I think there was a lot against us. (The season) was brutally short. We said goodbye to four people in one episode. I mean, come on. And it wasn’t the right chemistry on the panel.”

More than that, Sebastian lambasted fellow judge Iggy Azalea for her lack of commitment to the cause throughout filming.

“She’s a bit of a weirdo. I don’t really get Iggy,” Sebastian said. “You’ve got to be invested and she didn’t turn up.”

It’s not the first time Sebastian has lamented Azalea’s lack of professionalism on set, telling The Advertiser in early November that he struggled working alongside the US-based rapper.

“Yeah we clash. We’re just not similar people at all and I definitely have to bite my tongue,” Sebastian admitted.

“All I’ll say on the matter is, I think it reflects poorly on the show when it seems someone is not invested in it.”

It is unsure whether X-Factor will return in 2017 for a ninth season, after big-name recruits Adam Lambert and Iggy Azalea did little to boost ratings.
