Are MAFS Australia's Sierah and Billy still together?

Unfortunately Sierah and Billy from MAFS Australia are no longer together despite their initial connection.

After getting off to a strong start, things quickly took a turn when Sierah snuck off to attended an evening meal with MAFS stars Adrian Araouzou and Tony Mojanovski behind her husband's back.

Left devastated by the betrayal, Billy's trust in his wife was shattered, leading the pair to both write 'Leave' during one tension-filled commitment ceremony.

Speaking about how he felt at the end of their relationship, Billy told the experts and his wife: "I just feel like I've really retreated. I've got literally no deep connection from you, Sierah. I've got nothing.

"All I ever wanted was a deeper connection. How many weeks are we in now? I expressed every part of my life to you. My mum doesn't even know some of things I've told you. I have got nothing from you."

Intimacy Week issues

During intimacy week, it became clear that Billy and Sierah were on different pages regarding their physical relationship.
