Bronte and Harrison from MAFS could last, according to fellow groom Duncan James

Married At First Sight groom Duncan James believes volatile couple Bronte Schofield and Harrison Boon have what it takes to last the distance - despite their fallouts on the reality show.

James told AM their relationship was an interesting one that meant none of the other contestants on the show could see what would happen from week to week.

"I could see him and Bronte going all the way. Some of their behaviour and the way they act together, I'd say no way could they make it, every week it seems to yo-yo up and down," he told AM.

"They've definitely got the physical attraction to each other - I just don't know if they've got the right personalities for each other."

However, James has his own issues on the show, with his wife Alyssa revealing to the other women on on Monday's episode that he was "not physically my type at all".

"I don't want to paint him in a bad light, but he makes me out to be a person that's very needy and very naggy and I don't want to be that person," Alyssa said.

James told Ryan Bridge hearing that on national TV had left him "pretty upset".

"It's news to me, I'm pretty upset that I only just found this out but yeah I'm definitely not Alyssa's type as she told the girls last night - in the physical sense anyway." 

He said it felt "pretty bad" to be told that.

"I thought one of the things that we had as a cornerstone of our relationship was that we both had that instant physical spark when we saw each other walk down the aisle. To hear that was different, it's a very different image to what I thought Alyssa had of me."

Married At First Sight airs Sunday to Wednesday on Three and can be streamed first on ThreeNow.
