MARRIED at First Sight’s Susan Rawlings has lifted the lid on the show ahead of its much-anticipated finale week.

The Perth truck driver is so outraged by her treatment on the Channel 9 hit series, she has breached a confidentiality agreement forbidding her from revealing behind-the-scenes activities without the permission of the show’s producer, Endomol Shine Australia.

Rawlings, who was paired with Queensland cowboy Sean, feels morally obliged to speak out despite the risk of being sued.

She felt she was denied “basic human rights” because she had to beg for toilet breaks during eight-hour dinner parties and commitment ceremonies.

“A producer would come out and yell at us saying we can’t go to the toilet,” she said.

“He said we aren’t school children and that we can hold it. Sometimes I was so angry that I felt like my bladder was going to burst.”

At one point, participants pulled rank and refused to speak on camera until they were allowed to empty their bladders.

Rawlings said dinner parties and commitment ceremonies were held during summer heat in a warehouse with no air-conditioning and a fireplace for “ambience”.

She said portable air-conditioners were added after constant complaining but they were ineffective.

Participants were sleep deprived because filming finished up between 2am and 4am, immediately followed by one-on-one interviews.

Rawlings said participants suffered dehydration because they had limited water at commitment ceremonies. The 37-year-old also accused producers of feeding her lines, saying production staff attended her hotel room with a script.

“They read out sentences to me, which I then had to repeat back to the camera,” she said.

Rawlings said producers told her to make a big deal about a pasta bake strewn over Sean’s front lawn when she attended his farm.

After seeing the episode, Rawlings told producers she was having a hard time dealing with her portrayal but they told her not to worry.

“So I’m absolutely furious that no one from the show has ever contacted me to this day and asked if I’m OK or offered me any support,” she said.

Rawlings said producers fed the show’s psychologists lines, via ear pieces.

“It’s absolutely fake and excruciating to live through,” she said.

“It’s an absolute sham because we are not talking to the experts and they are not talking with us. They are just pawns in a game.”

Footage of the couple’s final vow ceremony, screened last week, made it appear as though Rawlings dumped Sean.

“The editing team completely twisted it all around so that it looks like Sean went first and said that he wants to stay with me and ride off into the sunset together,” she said.

The Craigie resident said the break-up was a mutual decision but producers edited out Sean’s final line in which he said he didn’t want to continue their relationship.

She said the producers wrote two pages of her vows and she wrote three. Despite reading out all five pages at the ceremony, producers mainly aired the vows they had written for her.

An Endomol Shine Australia spokesman said it took its duty of care seriously “All participants are given adequate food, water and breaks and have access to psychological support, which has always been available at any time throughout the show and continues to be,” the spokesman said.

“Our production is also in regular contact with the participants and are diligent in reporting any concerns to our psychologist. We take our duty of care extremely seriously.”

Another current Married at First Sight participant, who declined to be named, believes cast members were deliberately agitated to evoke emotion.

The source said they were made to stand in separate corners of a stinking hot factory and told not to speak or move for up to four hours, before filming.

They also claimed couples were fed lines and would often have to fake their reactions due to multiple takes of the same scene.

Participants were paid $200 a day to cover living expenses. Some have been offered a trip to Fiji to cope with stress.
