Sonia is a veteran of the show - which debuted in 2001 – having previously hosted between 2012 and 2014.
This time around however, the show looks to be a whole lot different. There’s a new house, new rules and no live format.
The show’s official Instagram page merely states “The game has changed”. But, according to a report on industry website TV Blackbox, the new format will be akin to ‘Survivor in a warehouse’.
The publication also shared that the show will be filmed in Sydney at the same location used for The Biggest Loser Australia: Couples.
Sonia’s announcement as Big Brother 2020 host comes mere months after she announced she was leaving Channel Nine.
The 54-year-old confirmed she’d be returning to Channel Seven in a statement, “I'm beyond excited to be returning to the network where I first discovered my love of live television and family entertainment.”
“With the upcoming Olympics in Tokyo and a slate of brand-new prime-time shows, Seven is the place to be,” she added.
Channel 7 will certainly be keeping Sonia busy. As well as Big Brother 2020, she’s also set to host Mega Mini Golf and act as a judge on Australia's Got Talent: The Champions.
Her first gig at her new home channel airs on Sunday, February 16 and will see her present the bushfire relief concert Fight Fire Australia.
