Brittany Higgins plans to push Scott Morrison for changes to workplace culture in Parliament House when the two meet as early as next week.
The former Liberal staffer, who alleges she was raped by a colleague in a federal minister's office two years ago, has accepted an invitation to meet with the prime minister.
"This decision wasn't made lightly," Ms Higgins said on Wednesday.
"However, things cannot be improved unless people are willing to come together and speak plainly about these difficult issues."
Ms Higgins said it was disappointing she had not heard from the prime minister's office since they initially made contact on April 6.
"I'm hopeful the meeting will proceed," she said.
"After two months, a national protest and countless other horrifying stories, the time for action is now."
Mr Morrison said organising the meeting was "in process" and claimed his staff heard from Ms Higgins last week.
"It's an important meeting. I'm looking forward to having it," he told reporters on the NSW Central Coast.
"We've been obviously following up on that now, and I look forward to having a meeting arranged soon."
