They also happen to be incredibly likeable and relateable and they’ve been refreshingly honest about their relationship both on-screen and since the show ended.
Once the cameras stopped rolling the Melbourne couple, who have now been together for a year, got on with the business of being together.
Zoe has been speaking up about miscarriage since the finale of Married at First Sight.
And back in the real world, real things happen.
To the couple's delight, Zoe fell pregnant, but she suffered a miscarriage during the first trimester.
They were both devastated and struggled to cope with the loss. Now, Zoe wants the subject of miscarriage to be something that's spoken about openly, and not a taboo subject for couples to endure alone.
She chatted to Mamamia about her pregnancy and miscarriage, why she's speaking up about it, and what life's like after marrying a stranger on a reality show.
Zoe and Alex on their wedding day.
Zoe and Alex told the whole country about Zoe's miscarriage on A Current Affair on her and Alex's first wedding anniversary.
"That really was a big moment for us to get that news out there," she says. Alex picked her up from the train station and they spent their anniversary watching the show, eating takeaway and going through photos of their year together.
She wanted to share her experience with miscarriage with other women who have been through the same thing.
"I've had an overwhelming response from women and saying, 'This happened to me.' And they tell me their story. And I think in a lot of those cases, they haven't shared that with anyone. Not their friends or family, because they've never felt that anyone wants to hear it," she says.
"It can be uncomfortable, so people then think, 'I don't want to make you uncomfortable even though I need help.' So I feel really honoured because I struggled, I really did. I was in a horrible place."
After the miscarriage, she had to deal with a tabloid article speculating that she'd had a baby.
"I unfortunately was also dealing with the fact that New Idea had that story out [about a photo of Zoe and Alex holding a baby that that the magazine alleged was theirs] and people were congratulating me on the street. That was a couple of days after we found out the bad news and it was a bit bizarre."
She thought the miscarriage was her fault.
