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.
Theyโll 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.
โIโve never been in love,โ she confessed.
โIโm scared that my future husband will be disappointed when he sees me. Iโm scared to be vulnerable and let my guard down, but Iโve been single for so long and Iโve never been in love before. I really want someone to take the time to get to know me.โ
England-born Billy, a 31-year-old plasterer from Western Australia, shared the same sentiment as he hoped his new bride had โthe biggest smile on her face when she sees [him].โ

He is looking for โmiss perfect,โ someone to spoil, confident, and positive as Billy is known to wear his heart on his sleeve.
โI love, love,โ Billy said. โIโve got a lot of love to give.โ
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 Sierahโs connection continued to grow, bonding over their shared love of animals, and feeding each other food โ despite Billyโs โstingy mouthful.โ

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 couldnโt open up to her husband.
Ultimately, Billyโs trust in his wife was broken, leaving both participants to write exit in their final commitment ceremony.
โAll Iโve ever wanted was a deeper connection, and Iโve gotten nothing. How many weeks weโre in now? Iโve tried to give you what you needed, but you donโt give me what I need,โ he said. โI donโt know why, because Iโve expressed every part of my life to you โ my mum doesnโt even know some of the things that Iโve said. Iโve tried, because Iโve come into this experiment with an open [mind] because I havenโt been like that in previous relationships. Iโve gotten nothing from you Sierah.โ
