Ms Husar, a first-term MP for the western Sydney seat of Lindsay, announced in August she wouldn't contest the next election after being accused of bullying staff.
The 44 allegations levelled at her were not the reason behind her decision, but rather the extraordinary media attention around the harassment claims and "the slut shaming that went along with that".
"That's actually what brought my career in politics to an end was being slut- shamed so viciously, with no ability to come back and stand up for myself," she told the ABC's 730 program on Tuesday.
"I guess slut shaming is the oldest trick in the book to bring down a woman. It's almost used as a method of torture."

More than half of the allegations were made by a former staff member, whose probationary period was extended in September last year over "poor performance", the MP says.
Ms Husar says Labor leader Bill Shorten provided support during the public ordeal.
"They are words I will always remember: 'I believe in you. I believe you,' she said.
The allegations levelled against Ms Husar included that she bullied and sexually harassed her electorate office employees and diverted Labor funds into her personal bank account.
She was also accused of exposing herself to Labor frontbencher Jason Clare while he played with his young child in his office.
"It's utter garbage," Ms Husar said.
"You've had both me and Jason Clare on the record saying it didn't happen."
Ms Husar directly addressed some of the headline grabbing allegations, such as having a turnover of more than 20 employees in her electorate office, swearing at staff and talking about sex in the office.
"Let me be clear - I have had seven full-time staff in a two-year period," she said.
"I swear a lot. But, you know, in a frustrating high pressure work environment ... I don't swear at people."
The Lindsay MP said conversations about sex occurred in her office because she wanted to brush off rumours being spread about her.
"As a way of kind of batting it off and brushing it off and showing that I'm still fierce and I'm still tough in the face of it," she said.
Two days after Ms Husar announced her decision to quit, Labor released the results of an internal investigation clearing her of allegations of lewd conduct and sexual harassment of employees, finding there was no need for her to resign.
However, the report did find she behaved unreasonably towards staff and there were grounds for a further investigation into the alleged misuse of entitlements.
The investigation into Ms Husar's office dragged on for months, but only became public in August when some details leaked - which the report found was "reprehensible".
