Shelly Horton will be joined each week by special guests, to review the latest Married at First Sight episode and talk viewers through all the gossip.

In this social experiment, smoking-hot celebrity singles think they're running away to paradise for a once-in-a-lifetime romantic vacation full of fun and sun. But just as the party is getting started, unwanted guests arrive to break up their good time.

Hosted by Brihony Dawson and filmed in Buenos Aires, Argentina, The Challenge Australia will see an algorithm randomly pair challengers to compete in gruelling physical contests, test strategies, survive eliminations, cutthroat alliances and steamy hook-ups to win daily challenges and eliminate their opponents.

Australian celebrities are dropped into the African jungle with little more than their wits, strength and willpower to survive the competition. How will they cope with African wildlife, a constant series of challenges and tests, basic rations and their fellow campmates? Who will survive the infamous Bush Tucker Trials? Who will win the hearts of viewers and be crowned King or Queen of the Jungle?
