One female Liberal backbencher says it's "disgusting" they have been told not to attend the speeches of Grace Tame and Brittany Higgins this week.
Ms Tame and Ms Higgins will front the National Press Club on Wednesday after making their opposition to the prime minister's treatment of women and lack of action on women's issues well known.
A Liberal backbencher told AAP pressure was being applied for MPs not to attend the event, in order to avoid embarrassing the government.
"There's no trust in us (MPs), so it can't be reciprocated," the backbencher said.
"The prime minister can't have it both ways. (Scott Morrison) can't say he doesn't trust us to act in the interest of the party and the government and listen to (concerns) about an important issue in parliament and the country."
It is understood that some Liberal cabinet ministers will be attending the speech.
Ms Tame is a survivor of child sexual abuse and has been vocal in her criticism of the coalition government's response to women's safety issues.
Ms Higgins is a former Liberal staffer who came forward with an allegation of sexual assault in a ministerial office in 2019 and has been championing safety reform in parliamentary workplaces.
It comes as the government is due to act on two key recommendations from a review into parliamentary culture by sex discrimination commissioner Kate Jenkins this week.
Ms Jenkins outlined 28 recommendations in her Set the Standard report.
A specialist taskforce, chaired by former public servant Kerri Hartland, has been set up to ensure all recommendations from the landmark review are implemented.
The review found one-in-three people working in Parliament House had been sexually harassed, with 11 per cent reporting it.
About one quarter of workers told the review their harasser was a politician.
SBS News has contacted the prime minister's office for comment.
