Several Married At First Sight Australia contestants have reportedly been forced to seek refuge in safe houses following intense public backlash from viewers.

According to the Daily Mail, Jessika and Dan - now infamous for their on-camera affair - along with Martha and Ines, were all booked into secure rental properties ahead of the show's finale.
Producers at Nine Network are reportedly looking to ensure the physical safety of the cast, after an influx of threats from fans.
"This year the level of threats and hate has been unprecedented," an on-set source allegedly told the Daily Mail.
"Although most of [the violent threats] have no credible basis and are just trolls on social media, producers are really worried the reunion may push some viewers over the edge.
"They are prepared right now for an intense public backlash against some of the participants."
Jessika's aunt Rebecca recently told the Daily Mail she had been fielding some of the abuse directed at her niece, who forced husband Mick to stay in the experiment for weeks so that she could pursue Dan, who was then married to Tamara.
"Jess is waking up every day to people telling her to kill herself and that she needs to die," she said in an interview.
"I'm copping threats too from local people, and so are the rest of the family."
