Morrison’s comments came hours after The Australian newspaper and Channel 10 reported allegations and images from an anonymous whistleblower about lewd behavior by male government staff in Parliament House.
They featured the men filming themselves performing solo sex acts, including on the desk of a female Member of Parliament.
One government staff member has been removed from his position, a government minister said on Tuesday.
Morrison described the report as “disgusting” and said he would speak with all government staff members on Tuesday to remind them of their responsibilities.
The issue spurred tens of thousands of people to rally around Australia last week and led to a slump in Morrison’s standing in opinion polls.
Morrison has sought to defend his government’s actions in working to improve gender equality, but on Tuesday he accepted there was broad dissatisfaction.
“I acknowledge that many Australians, especially women, believe that I have not heard them, and that greatly distresses me,” Morrison told reporters in Canberra.
“We must do better… we must get this house in order.”
However, he offered few concrete proposals to improve the workplace culture in parliament, insisting that changes would be announced in the coming weeks.
