Fallout and final vows: Married At First Sight couples after season 12 finale

The season has been dominated by scandal with NSW Police investigating a domestic violence allegation against Carina's partner Paul and Jacqui seeking an interim restraining order against her on-screen husband Ryan.

Only two couples remained committed to each other after final vows, three if you count Awhina and Adrian's shortlived backflip, but sources have indicated there may be trouble in paradise.

Golden couple Jamie Marinos and Dave Hand started the 'experiment' strong, forming an early bond, but started to wobble after the new bride declared her feelings of love.

The pair committed to stay together in their final vows with Dave saying he was proud of the relationship he had with his "pocket rocket".

But fellow MAFS groom Adrian Araouzou has suggested in a TikTok live video that the pair split after filming wrapped.

Australia watched in shock, and occasional horror, as Awhina and Adrian's 'marriage' played out in MAFS season 12.

Cracks in their relationship began to show during their honeymoon and the fissures only deepened as the pair got to know each other.

Adrian briefly disappeared from the show, offended that he hadn't been included in a promo shoot, but returned to finish the series.

At the final vow ceremony, they agreed it would be better for them both to "walk away". But in a last-minute backflip Awhina asked if Adrian wanted to "see where it goes".

Awhina has said that the pair "still speak daily" despite reports that Sydney-based Adrian ghosted his Western Australian 'wife' after she returned home.

Carina Mirabile and Paul Antoine were given a second chance at love when the experts matched the pair in the 'experiment'. The couple revealed that they had already been on a date before Paul ghosted her.

Paul continued to "disappoint" his wife by allegedly punching a wall, calling her a snob and going on a date with another woman.

At the final vows she said "the trust is broken and I can't come back from that".

"You were given a test which you failed, in my eyes that's the final straw," she said. "I can't be with someone who makes me feel like I'm not enough".

"I choose me," she said on social media after the final vows aired.

Melbourne-based couple Rhi Disljenkovic and Jeff Gobbels emerged from season 12 as the strongest 'marriage' after an unexpected journey.

The pair revealed at their wedding ceremony that they had also previously dated, after meeting at their gym, and had decided to transition into a friendship.

But, with the help of the experts, the couple confessed they were "falling in love" with each other during their final vows.

"He's like a best friend and a partner wrapped in one," Rhi said. "I'm ready to do life with him."

Australia watched in confusion as Jacqui Burfoot and Ryan Donnelly continued to commit to their relationship as they traded jabs back and forth.

But ultimately the "roadblocks" were "impossible to overlook", Ryan said at the final vows ceremony.

"Ryan, in a world of red flags, you are the red carpet," Jacqui bit back.

The pair's volatile relationship has allegedly continued online after MAFS season 12 filming wrapped with Jacqui winning an interim restraining order against Ryan in a Launceston court on March 31.

The order stops Ryan from commenting on social media about his former 'bride'.

Jacqui has reportedly moved to Tasmania to explore a relationship with Clint Rice, who was matched with Lauren Hall in the same season.

It's unclear if the relationship between Jacqui and Clint started during or after filming, but the pair appear on social media to be blissfully happy together.
