Who won Big Brother Australia 2021?
On Monday night after 63 days and 26 housemates, Ari, Christina, Marley and SJ celebrated making the final four with a champagne breakfast and video calls from home. They faced one last monumental hurdle before getting to the Grand Final. The winner of the last nomination challenge would have the power to choose the final evictee from Big Brothers game, ultimately deciding who they want standing next to them on the podium, with a one in three chance of taking home $250,000.

A triumphant Marley looked to the sky, saying: The only reason I got to the end of this game is because of mum. I asked her for help and she gave it to me and allowed me to be in this position.  Marley then had to decide which two housemates to take to the Grand Final and who to send home, torn between using his head and evicting strategically, or going with his heart and staying true to the person hed been the whole game. In the end, Marley voted with his heart, saving SJ and Christina and evicting Ari, who walked out of the ceremony without saying goodbye.

Im such a competitive person and if I dont win something I feel like a complete failure, so Im absolutely gutted. Im proud of myself for making big moves. I got rid of some huge players, I wasnt scared to play a risky game and I won four challenges. Im proud of that stuff but Im so devastated that I have lost tonight.
