It was undeniable that Billy and Sierah had instant chemistry with their shared sense of humour and loveable energy on Married At First Sight Australia 2025.
They’ll undoubtedly turn heads throughout the MAFS experiment as one of the many couples searching for true love.

Sierah is a 31-year-old financial associate advisor from Victoria with little experience in relationships, with four months being the longest.
“I’ve never been in love,” she confessed.
“I’m scared that my future husband will be disappointed when he sees me. I’m scared to be vulnerable and let my guard down, but I’ve been single for so long and I’ve never been in love before. I really want someone to take the time to get to know me.”
England-born Billy, a 31-year-old plasterer from Western Australia, shared the same sentiment as he hoped his new bride had “the biggest smile on her face when she sees [him].”

He is looking for “miss perfect,” someone to spoil, confident, and positive as Billy is known to wear his heart on his sleeve.
“I love, love,” Billy said. “I’ve got a lot of love to give.”
Given their past, personalities, and desires for a romantic partner, we think the relationship experts may have nailed this MAFS 2025 match.
Following the wedding, Billy and Sierah’s connection continued to grow, bonding over their shared love of animals, and feeding each other food – despite Billy’s “stingy mouthful.”

All in all, the experiment seemed to be smooth sailing for Billy and Sierah, aside from a few hiccups during Intimacy Week where the bride felt there was a lack of physical connection between the pair.
However, the rose colour glasses cracked when Sierah confessed she emotionally opened up to another groom, Adrian, yet couldn’t open up to her husband.
Ultimately, Billy’s trust in his wife was broken, leaving both participants to write exit in their final commitment ceremony.
“All I’ve ever wanted was a deeper connection, and I’ve gotten nothing. How many weeks we’re in now? I’ve tried to give you what you needed, but you don’t give me what I need,” he said. “I don’t know why, because I’ve expressed every part of my life to you – my mum doesn’t even know some of the things that I’ve said. I’ve tried, because I’ve come into this experiment with an open [mind] because I haven’t been like that in previous relationships. I’ve gotten nothing from you Sierah.”
