Prime Minister Scott Morrison says setting a "tone and culture" is the best way to deal with allegations of bullying and harassment in the Liberal Party.
There have been suggestions the party should set up an internal panel to deal with bullying complaints.
The pressure of the past week - in which minister Peter Dutton twice challenged for the leadership which was eventually won by Mr Morrison - led Victorian Liberal MP Julia Banks to announce she was quitting politics because of "vindictive, mean-spirited" behaviour.
Mr Morrison said he had been touch with Ms Banks, and senior Liberal members - whip Nola Marino and minister Kelly O'Dwyer - had been talking to colleagues after a "very bruising week".
"I don't have any truck with bullying - I stand up to bullies as well, as people know," he told reporters in Jakarta on Friday.
"I'm setting a tone and culture I expect all of my colleagues to follow and I know they will."
Former minister Craig Laundy said an internal panel was needed to deal with bullying complaints, as parties should not consider themselves above Australia's workplace laws.
"Any employee in this country is entitled to not only a safe work environment but, if bullied or intimidated, avenues for resolution of conflict," the Liberal backbencher told The Australian.
South Australian Liberal senator Lucy Gichuhi said there is no place for bullying and harassment in parliament.
"No workplace, including parliaments, should tolerate bullying and intimidation, which is ANY act directed towards another's mental, emotional, financial, social and even political capacity; preventing their wilful, free and independent decision-making," she posted to social media.
"This is also harassment."
Defence Minister Christopher Pyne believes complaints of bullying should be dealt with by the normal process, through Ms Marino.
It is understood Ms Marino has not received any formal complaints.
Senior Labor MP Anthony Albanese said Ms Banks' retirement was a tragedy.
"It's tragic that someone feels like they would rather leave the parliament than sit in the Liberal Party caucus room, but that is where it has got to," Mr Albanese said.
Trade Minister Simon Birmingham said he expected the whips and presiding officers would look at the issue and consider if any other action is needed.
Liberal Party Women's Council chair Helen Kroger denied her party fostered a culture of bullying and intimidation, and described politics as a "rough and tough" game.
