Picture this: Your favourite (and let's be honest, least favourite) reality TV stars all on the same show, shading, fighting and competing against each other in some kind of sadisticBig Brother/Survivor/Ninja Warriormash-up for... bragging rights, probably, and a RIDICULOUS amount of money.

As you're probably all very aware by now, that is actually a thing that is about to happen.

It's calledThe Challenge: Australia, and it's going to be the best or the worst thing we've ever watched. Perhaps both.

Watch: The trailer for The Challenge: Australia. Post continues after video.

Here is everything we know so far about the new reality show.

What isThe Challenge: Australia?

The series is based on a long-standing MTV series in the US, which has already aired for 37 seasons. That's... a lot of former reality stars.

It features reality alumni competing in a series of physical challenges to avoid elimination. They all live in a house together too – so you just know there's going to be plenty of drama and paranoia around alliances, hookups and budding relationships to keep us entertained.

The show has been filmed in Buenos Aires and will air on Channel 10 in November.

The prize is a bunch of new social media followers, $200,000 and entry into the inauguralThe Challenge: Global Championship, where they will represent Australia against contestants from Argentina, the UK and US in the hopes of becoming the first 'Challenge World Champion'.

So the trailer's been released... What happens?

We're glad you asked, because it's a heck of a lot.

'Cyclone' Cyrell comes out again.

It looks like MAFS star Cyrell Paule will be bringing the best drama of the season yet again after the infamous 2019 wine fight.

In the teaser trailer, shouting expletives with a glass of wine in her hand.

Konrad Bien hooks up with Megan Marx, allegedly.

Bacheloralums, Megan Marx and Konrad Bien, are shownallegedlyhooking up onThe Challengemoments before news came out that he had broken up with Abbie Chatfield. Awks.

Brittany Hockley isn't happy about something.

While we know literally nothing about what's to come, it looks like it will be good considering podcast star Brittany Hockley is in a clash with someone off-screen. And yes, that is Brooke Blurton awkwardly watching on at the events unfolding.

"You are one hundred per cent trying to make it about something it’s not," she can be heard saying.

Who will appear on the show?

The entirety of Australia basically knew who would be on the show before the cast list was officially announced. Because as we now realise, reality stars are terrible at covering their tracks.

The Daily Mail captured every one of the stars at the airport as they flew out to film. According to the publication, The Bachelorette's Konrad Bien andAustralian Idol's Emily Williams were also seen boarding a flight to Argentina via Auckland, presumably for the show.
