While she remained tight-lipped about it for most of the season, Abbie discretely told Matt through a "whisper", however, grew angry when producers tried to catch the moment on camera.
"I whispered it to him and his producer didn't hear me and said, 'Abbie, you are going to have to say it out loud.' And then I turned around, looked dead in the camera and said, 'I had a f**king abortion last year.'"
After "begging" Network 10 producers to edit the emotional moment out, Abbie decided to share her story in an attempt to remove the stigma surrounding terminations.
"In the house, I told the girls about my abortion... because I didn't want other women to feel ashamed about having abortions and I feel like it was used against me," she revealed. "A lot of women have abortions and, whether or not you know they have abortions, it's OK. I just don't want people to be shamed for that or feel internal shame.
"Maybe someone who's kind of in the public eye saying they've had an abortion and that it's OK will help them [women who've had abortions]."
