Joel Madden's brother and Good Charlotte band-mate Benji will take to the coaching chair for the first time, joining forces with his twin, while former Spice Girl Mel B has traded in her X Factor duties on a rival channel for a gig on the popular Channel Nine program.

The group wrapped up four days of live auditions at Fox Studios on Thursday with no word on when viewers can expect the show to go to air.

Goodrem said she was excited to be part of the new program.

'I am so excited to be a part of the debut of The Voice Kids and discovering the next generation of Australian talent', Delta said.

She said being part of The Voice Kids allows her the time to continue working on the show and to focus on new music.

The songstress flew in from Los Angeles last week, where she is based.

Last year marked a decade since Delta released her first album as a 19 years old.

The four personalities took time out from their coaching roles to play up to the camera.

'I think @TheVoiceKidsAU is gonna be a really cool thing to be a part of, watching these kids live their dream. I can't wait to meet them all.'
