After a six year hiatus (and months of waiting), Big Brother Australia is finally returning to our screens.

On Monday June 8, we’ll watch 20 strangers live, eat and share their secrets on national television, all for the interest of our entertainment. And we have never been more excited.

While this season will see the return of 2012Big Brother host, Sonia Kruger, the show will look very different this time around.

Watch a sneak peek of the new season of Big Brother below. Post continues below.

Not only will this season incorporate new challenges, but we’ll also see a completely different mix of contestants other than the usual bunch of young singles.

The youngest contestant this season is 19, while the oldest contestant is 61.

Unlike previous seasons, the series, which has been pre-recorded, will run for seven weeks on three nights a week – Sundays, Mondays and Tuesdays. The series will end with a live finale, when Australia will get an opportunity to vote.

Here’s everything we know about theBig Brother 2020housemates.

Sarah, student

Meet the youngest person in the house: Sarah.

She is 19 years old, still a student, and is from Pakenham, Melbourne.

At just 4’11”, Sarah is described as a pocket rocket with a big personality.

Talia, trade assistant

Talia works in construction, helping to manage a site of 50 men.

“She is very strong willed, especially in arguments, and thinks her stubbornness may lead to some tense moments with the other Housemates,” Channel Seven said.

Kee Reece and Laura Brodnik chat about the Big Brother housemates on Mamamia’s daily entertainment podcast, The Spill. Post continues below.

Shane, marriage celebrant

Shane is a husband and father of three, and is hoping to winBig Brotherso he can spend the money on his friends and family.

From Tweed Heads, Shane now works as a marriage celebrant, but his previous jobs include being a DJ, MC and airline cabin crew.

Hannah, communications expert

Hannah is a 26-year-old from Perth, Australia. She is single, and currently lives in a share house.

According to Channel Seven, “Hannah can’t stand people who are full of themselves or selfish and says that lying men and bitchy girls will push her over the edge.”

Xavier, medic

Xavier, who Channel Seven says is known to be a troublemaker, will also be entering theBig Brotherhouse this year.

“Xavier is adept at reading others and can manipulate a situation to the point that no-one will have any idea he’s the one running the show,” the broadcaster reports.
