Big Brother 2020: The late arrivals are kept on their toes as a shock twist sees them attempting to go unnoticed in a nail-biting trailer for the reboot

The reboot of Big Brother premieres on Channel Seven on Monday night.

And a nail-biting trailer shared to the show’s official Instagram page on Sunday, sees four late arrivals attempting to go unnoticed.

Chad, Sophie, Garth and Sarah had to go undetected in the house, while the first batch of stars were sound asleep.

Black and white footage saw the soon-to-be household names creeping into the bedroom as they searched for their own bed.  

They were told by Big Brother that they ‘must find the bed without being detected’. 

Sydney-based model Chad, 27, went shirtless as he remarked on camera: ‘Gotta be super quiet!’
