It’s fair to say that viewers are loving Channel 10’s reboot of Big Brother Australia. Not only have fans been glued to the show’s 24/7 livestream, but the reality show has been praised for showcasing ‘real’ contestants having honest conversations in the house.

Now, two weeks into the season, the competition is heating up. Channel 10 has confirmed to Yahoo Lifestyle that Sunday night’s episode will feature a shock double eviction.

“This will be the biggest twist of the season,” host Mel Tracina said.

Who is up for eviction?

Following 49-year-old publisher Michael’s elimination on Sunday, the housemates nominated three women for eviction this week.

This includes 23-year-old Bunnings worker Mia, 45-year-old social worker Allana, and 67-year-old retiree Jane.

This marks the second time Jane has been up for eviction after she failed to complete a task in her first week and was automatically nominated.

Fans divided over major twist

Viewers have had mixed reactions on social media to this week’s double eviction, with many complaining that this wasn’t announced during Monday night’s nominations episode.

“They did us dirty by not revealing this when the vote opened,” one person wrote.

“Revealing after the vote had already opened that it’s a double isn’t great,” another agreed.

A third argued that the Channel 10 programme should have brought this in for next week and put every housemate up for eviction.

Meanwhile, others argued that this twist technically “makes no difference” as viewers are meant to vote on who they want to save, rather than who they want to evict.

How long will this season run for?

While Channel 10 has yet to confirm when the season will end, Yahoo Lifestyle understands that the show will be done before Christmas.

That means there are fewer than five weeks to go, which could suggest there will be more double or triple evictions in the future.

This will also make it the shortest season of Big Brother Australia to air on Channel 10, as earlier seasons ran for 85 to 100 days.

However, the final season to air on Channel 7 in 2023 was filmed over just 25 days, which is the shortest non-celebrity season in the show’s history.
