Another season of Married at First Sight is about to kick off on TV3.
The reality show brings together complete strangers in a quest to find love - without seeing each other until the wedding.
However, they won't be alone, with relationship expert John Aiken will be on hand to help the couples.
"My role on the show - as an expert, I'm a psychologist by trade - is to essentially match the couples," he says.
"I'm also involved in explaining what's happening for the couples as they go along the experiment, and I'm there at the end when they make their decision to support them, whatever their decision or way they go."
The show is based on analysing data on the prospective pairings.
"We arrange marriages based on science, and then we bring couples together, and then we put them in an experiment for four weeks," says Aiken.
"At the end of those four weeks they decide whether to stay, or whether to go. So it is a really unusual concept, but it's one that's had some success."
The show hasn't had the best luck however - and they're not the only show to pair up couples who meet at the altar for the first time.
The Edge is on a roll, with four weddings, eight strangers, eight offspring, 41 combined years of wedded bliss and no divorces - that's quite some record.
Zane and Paula Nicholls were married in 1999, after the first season of the Strangers and a Wedding radio hook-up.
They were followed by Steve and Kersha Veix in 2003, and Chantelle and Paul Court in 2007.
The latest couple was Aaron and Sade Schuurman, who married in 2016.
The Edge host Jay-Jay says there's a simple reason for their success.
"Part of it is getting friends and family to choose the partner rather than getting experts - they don't know the person," she says.
"The other thing is the people, the people that have got married, really wanted to make it work."
Aiken says appearing on Married at First Sight takes, well, a certain degree of desperation.
"I think first and foremost they've exhausted all the other avenues that have been out there for them to find true love," he says.
"And I think also there's a part of them that likes, or certainly doesn't mind doing it under a spotlight."
So, what's the secret to matching the right people?
"It's about getting them to love the person before they see them," Jay-Jay says.
"You don't want someone too hot, you want normal people."
Aiken believes in matching personality aspects.
"I'm really looking for three things. Are they warm, are they a risk-taker, or are they generally, relatively conservative," he says.
"The biggest one I'm looking at is their emotional stability."
And the secret to making it last?
"They've all been really good - their personalities work really well - their families and friends built relationships with these people," says Jay-Jay.
"By the time they all got married, they had learned so much about each other that they were already falling in love, and it was just meeting each other to see if they had that extra spark."
Aiken agrees with her assessment.
"Not everyone is going to be perfect on all of these scores, but you're basically putting them together knowing that there'll be a good fit."
Strange match-ups won't be all of the drama - as Married at First Sight is preparing to break new boundaries on TV.
"This is the first time we've had a same-sex couple on the show," Aiken says.
"It's exciting. I think it's really important. It brings that particular issue to the fore - particularly in Australia, where it's not legal."
For now, The Edge has the lead in arranging long-lasting marriages, but Aiken is hopeful the new season of Married at First Sight will help couples beat the odds.
"It is successful," he says.
"Whether it's more successful is hard to measure."
