Morrison’s comments came hours after the Australian newspaper and Channel 10 reported allegations and footage from an anonymous whistleblower about obscene behavior by male government staff in Parliament.
They featured the men filming themselves performing solo sex acts, including on an MP’s desk.
A government staff member has been dismissed from his post, a government minister said on Tuesday.
Morrison called the report “disgusting” and said he would speak to all government staff on Tuesday to remind them of their responsibilities.
The question prompted tens of thousands of people to rally in Australia last week and led to a collapse of Morrison’s position in opinion polls.
Morrison has sought to defend his government’s actions by working to improve gender equality, but on Tuesday he admitted there was widespread discontent.
“I recognize that many Australians, especially women, think I didn’t hear them, and that saddens me greatly,” Morrison told reporters in Canberra.
“We have to do better… we have to get this house in order. ”
However, he offered few concrete proposals to improve workplace culture in parliament, insisting that changes would be announced in the coming weeks.
