Seven Year Switch (AU)

Four couples on the brink of separation will live with a total stranger, as they embark on a new social experiment where they will put their relationship on the line in order to save it.

Now separated from their real partners and with the shock of finding only one bed in their new home away from home, the new couple pairings start getting to know one another fast.

In this episode, our couples get to participate in their interests and their experimental partners interests, to bring them closer together. Brad and Jackie do golf, and Jason teaches Cassie drums.

This week, the couples go on a weekend getaway. Tim and Tallena visit Airlie Beach and get to the chopper for a private island picnic, while Ryan opens up to Michelle in Tasmania's Cradle Mountain.

Back from their weekend away, 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 their patterns of behaviour.

The experimental relationships are nearing their completion. But for Brad and Jackie the honeymoon is over. They have a big blow up and therapist Jo Lamble has to intervene to help sort the issue.

With just two days left in the experiment our couples are about to meet each other's partners for the first time. Cassie's meeting with Michelle raises more questions than it answers.

After weeks living in an experimental marriage, our couples reflect on everything they've learned during their time together before they are finally reunited with their partners.

Tallena returns home after spending nights away from Brad. And for the rest of the couples life at home has it's ups and downs. The therapists return to counsel the reunited couples.

Seven Year Switch returns when all four couples are brought together for the very first time. In a candid expose we'll find out what happened to each couple after the filming finished.
