Some Married At First Sight Australia contestants say they were matched with people whose criminal convictions were never disclosed to them, leaving them feeling unsafe on a show built around instant trust. The issue has resurfaced after a investigation found that nine former cast members are now calling for stronger background checks and clearer consent before filming begins.
The timing matters because the franchise still has a large audience in Australia and the UK, and the latest claims go to the heart of how much the production tells people before placing them in close quarters with strangers. Sierah Swepstone said she was cast with Billy Belcher and only learned after the show ended that he had been arrested and sentenced in 2014 for multiple drug-related offences in Perth. Another woman from last year’s Australian series said she was not told the man she was matched with had a previous drug conviction, while another groom had a past conviction for affray.
Swepstone said the experience should have come with full disclosure. “There should be informed consent,” she said, adding that “you shouldn’t be left alone with a stranger with a criminal record.” Her comments sit alongside the wider push from former participants, who want the programme to improve vetting and keep people with previous convictions or allegations off the show entirely.
That demand lands directly against the position of Channel 9 and Endemol Shine Australia, which said they had strong protocols in place to ensure participant safety and wellbeing. Channel 9 also told the that its protocols did not include sharing personal or background information between participants. In other words, the production says it has safeguards, but several former cast members say those safeguards did not amount to meaningful warning or choice.
The concerns are not limited to the Australian version. The report follows Panorama coverage of rape allegations from two women contestants in the British edition, allegations the men involved have denied. It also comes as the broadcaster has pulled all UK episodes of Married At First Sight from its All 4 streaming service, a move that has already put the format under a sharper spotlight. The said some of the criminal histories it identified had already appeared in Australian media, while others were reported for the first time, with many details found in court records on a publicly accessible database.
For now, the unanswered question is whether the show changes anything beyond its public assurances. Former cast members are asking for a different standard: not just background checks, but disclosure that lets people decide whether they want to walk into the experiment at all.
