All the fireworks of the Married At First Sight final

AUSTRALIAN TV's controversial 'social experiment' has drawn to a close, with some success.

Married At First Sight used expert matchmakers to pair four couples who met at the altar and then spent a month living together.

In tonight's final, three of the couples made the decision about whether or not to continue with their relationships after the cameras stop rolling.

Roni and Michael, who had sparks at their wedding, had already called it quits after Michael admitted to not feeling in love with Roni.

Michelle and James's decision was preempted by recent media reports that the couple had broken up after the show and that Michelle had reconnected with an old flame.

But there was still some genuine tension as the other two couples - Lachlan and Clare and Zoe and Alex - made their declarations.

While Alex and Zoe had the least amount of chemistry at their wedding, the youngest singles of the experiment gradually connected over their shared sense of humour.

They have even discussed adopting children and have bought a new dog, Winston, together.

"If we can feel what we feel in this small amount of time, then what are we going to be like in a couple years?" Zoe said.

"Sometimes you don't know what you need… and that's what the professionals do."

Clare and Lachlan, who had the most volatile dynamic of the couples, also decided to stay together.

"Just over a month ago I didn't even know Clare… we are where we are now and I'm very happy and excited about what lies ahead; (I'm) looking forward to the future," Lachlan said.

"We're taking the relationship slowly now post-experiment… we're working on how to integrate ourselves into each other's lives."

According to the show's psychologist Sabina Read, the experiment's success shouldn't be measured by how many of the couples stay together.

"Regardless of the outcome here I think there's a really rich learning opportunity for these guys," Read told APN.

"I don't see it (a couple breaking up) as a failure at all. I think that's a really simplistic lens for people to look through. The journey they've gone on is super important, as important as the outcome. There are plenty of people who are married who aren't feeling satisfied. Just being in the relationship isn't a blue-ribbon moment.

"For some of us knowing when to exit (a relationship) is just as important as when to be in one."

Channel 9 has already renewed Married At First Sight for a second season.
