Seven Year Switch - Episode Guide

Which couples will break up? Which couples will fall in love all over again? Which two couples will make a life changing decision?

The show that shocked Australia in 2016 returns in a brand new season. Four new couples take part in an experimental marriage with a total stranger in order to save their relationship.

Now separated from their real partners, our new 'experimental couples' reveal what's gone wrong in their relationships and what their hopes for the experiment are.

Learning to appreciate your partners' interests can help strengthen relationships. In this episode, our couples participate in theirs and their new partner's interests in order to bring them closer.

Therapists Jo and Peter check in for another session. It's a moment of truth for our experimental couples as they're shown video examples of tension in their real relationships.

After their first week of switch therapy, our couples embark on a weekend away. In Thailand, both Felicity and Mark drop their guard. In the N.T, Kaitlyn realises Mark must accept her for who she is.

Learning to appreciate your partners' interests can help strengthen relationships. Back from their weekend away, our couples learn this important lesson by planning their perfect first date.

Our couples are given a hundred dollars to buy a gift for their real partner. The pressure is on as they worry what messages their gift sends. Not all are received well and some expectations fall flat.

Each couple is shown photos of their real partner in their experimental marriages, and it becomes clear that each of them have dealt with the tasks and challenges differently.

After seeing photos of what their real partners have been up to, the rest of couples finally meet each other's partners. With trust, love and respect questioned, some couples are left heart broken.

The dust has barely settled after meeting each other's partners when another invitation arrives. This time, the husbands will meet each other and all the wives will have their own, separate dinner.

Our couples reflect on everything they've learned during their time together before they are finally reuniting with their partners. Letters from their partners produce mix results for the couples.

After weeks apart examining themselves and their relationships, our couples finally reunite. Michael and Felicity's reunion is warm and loving, but things don't go to plan for Stacey Louise and Sarge.

Jo Lamble and Peter Charleston return to counsel the reunited couples as they make the ultimate decision to either re-commit their relationship or walk away.
