Big Brother confirms 2021 cast (plus one intruder)

20 housemates go into Big Brother in the first week.... but what about one Intruder?

Seven has now released details of its full* 2021 Big Brother cast for the show’s return with host Sonia Kruger.

Their ages range from 21 – 66 from WA, SA, Vic, NSW and Qld, including Mary, mother of MAFS’ Martha Kalifatidis.

In the first week, 20 housemates will enter the Big Brother house where they’ll live together for more than 60 days, cut off from the outside world, with cameras and microphones recording their every move 24 hours a day.

There’ll be an eviction every episode in which housemates will individually vote to decide who will leave the house. Three housemates in a live Grand Final where viewers will choose who wins the $250,000 prize.

These are the cast confirmed in a media kit from Seven.

* But Seven has previously teased Brenton, a 31-year-old account manager from Sydney.

TV Tonight understands he will be an Intruder this season with others expected to be revealed.

This “very single” guy describes himself as a passionate person, and he’s playing Big Brother’s game to win. “I don’t go into anything to lose,” he says. “I’m going to use every skill I’ve got, whether its charming them with cooking or charming them physically. There’s not a single challenge that’s going to break me.” Will finding love in the house be Brenton’s weakness?

  1. IDK if having intruders works in this version of BB where the players can actively play (discuss who they want to vote off, etc). Surely any intruder player (who will enter weeks after the main cast), will be disadvantaged as the main cast would have already bonded well.
