Big Brother Australia 2021 has well and truly kicked into gear, with the current contestants battling it out like never before. And now, ready to shake things up, are six new intruders who are in it to win it. 

WATCH: Big Brother’s Ari reveals he’s been lying to housemates

This season of Big Brother promised more games, challenges and drama – and, boy, has it delivered so far.

While the location of the house – at Manly, New South Wales’ north head – remains the same, the house itself appears to have changed. And the labyrinth, combined with the games master’s constant schemes, continues to trip up the current housemates.

Ready to shake up the competition even further are six new intruders, who are joining the current housemates for a chance to be the last one standing. 

Without further ado, here are all the housemates, both in and out of the competition, on this season of Big Brother – including the show’s brand new additions.
