Married at First Sight Australia stars not told partners had drug and violence convictions

Married at First Sight Australia stars say the show left them feeling unsafe and unprotected because their on-screen partners had criminal pasts which they were not told about, a BBC investigation can reveal.

It comes after the British version of the show, known to many as MAFS UK, was plunged into crisis after BBC Panorama reported rape allegations from two women contestants - allegations the men involved have denied.

One woman from last year's Australian series says she was not told the man she had been matched with had a previous drug conviction and only found out after the show ended. "There should be informed consent," she told us.

We can also reveal that another groom from the same series had a past conviction for affray, which we understand his on-screen bride was not made aware of.

Nine former cast members from MAFS Australia have spoken to the BBC and are now calling on the show to improve its background checks and to stop allowing individuals with previous convictions or allegations on the show.

MAFS Australia is not made by the same production company as MAFS UK. Endemol Shine Australia is behind the show, which airs in Australia on Channel 9.

In a joint statement, Channel 9 and Endemol Shine Australia said they had "strong protocols in place to ensure participant safety and wellbeing".

As well as being a huge hit in Australia, the show is popular in the UK and is shown on Channel 4. The broadcaster has pulled all the UK episodes of MAFS from its streaming service All 4, but MAFS Australia remains available to watch.
