Greens Senator Sarah Hanson-Young has defended drawing her 11-year-old daughter into a political debate about sexism in politics, after a prime time TV interview sparked backlash on social media.

"My daughter has been watching all of this unfolding in the media," Ms Hanson-Young told the Seven Network.

"She said to me very clearly, 'mum, I want to be able to have my say'. And this was an opportunity for her to have her say."

The interview follows a public feud between Senator David Leyonhjelm and Ms Hanson-Young, where the NSW Liberal Democratic Party leader told his female counterpart to "stop shagging men" during a debate in federal parliament.

Senator Leyonhjelm then alluded further to her private life in an interview on Sky News.

In an interview with the Ten Network last night, Ms Hanson-Young's 11-year-old daughter Kora said Mr Leyonhjelm was a bully.

"Being unfair to women or any gender isn't right and he has refused to apologise and he deserved to apologise," Kora told The Sunday Project .

"I would say that being a bully was not right and I would try to stay confident which most women and young women must do."

Senator Hanson-Young told the Seven Network she was trying to protect her daughter.

"We try, of course, to shield our kids from many of the things that go on in the media, but when it is in their face and she is being confronted with these things in school, she said to me, 'mum, I want to be able to say how I feel'.

"My daughter is growing up. I think she is growing up and I am very proud of her and I am very proud of what you represent for all of the young girls across this country," she added.

"You don't have to put up with being disrespected or bullied just because you are a girl or a young woman. You have the right to have an opinion and you have the right to stand up to bullies."
