Brittany Higgins was not notified or asked for consent before the prime minister released a report into allegations of background briefings against her loved ones.
And the document repeated many of the claims that triggered the inquiry in the first place.
Scott Morrison tabled the report from his chief of staff in parliament on Tuesday.
He investigated whether the prime minister's office leaked negative information against Ms Higgins' partner in order to undermine her after she came forward with an allegation of rape inside a minister's office.
Mr Morrison said the backgrounding allegations were serious and he released the report in the interests of transparency, arguing the government would have been criticised either way.
"I have not made any comment on the contents of the report or repeated any of the matters in that report," the prime minister said on Wednesday.
"At the time of tabling the report, my chief of staff also contacted Ms Higgins and ensured she had a copy of that to ensure she received the report at the same time it was being tabled."
The report did not clear the prime minister's office of wrongdoing, but found there was not strong enough evidence to prove the claim.
Ms Higgins' partner David Sharaz is furious with how the release of the report has been handled and is not surprised by its findings.
"The PM's chief of staff undertakes an investigation into his own office and finds it's functioning well. How unexpected," he said in a statement.
"Even the most cynical person would see this for what it is: PMO staffers protecting themselves.
"We won't be intimidated by those who wish to silence us."
The opposition claims the report blamed journalists and not the prime minister's office for what Labor MP Tanya Plibersek described as "smearing" Ms Higgins' loved ones.
Mr Morrison has rejected the "caricature" of the report.
Since Ms Higgins came forward in February, Australian Federal Police have received 19 separate allegations of misconduct against politicians and staff.
Despite the flood of complaints, senior Liberal minister Jane Hume denied parliament was unsafe for women, but did concede an independent and confidential complaints system was desperately needed.
There is still no independent complaints mechanism in place at Parliament House, but Mr Morrison plans to consult party leaders on it next week.
Senator Hume said such a system was "exactly the right way to go".
"I can guarantee you mechanisms have improved dramatically just since the beginning of this year," she said.
An investigation into who knew what and when in the prime minister's office about Ms Higgins' alleged rape will be finished within weeks.
Home Affairs Minister Karen Andrews said changing culture in politics was more important than making the report public.
"We can spend a lot of trawling over who's said or done what but let's be very clear, we need to improve the standards here in this workplace and at many workplaces right across Australia," she said.
Ms Andrews also vowed to not get involved in any police investigation after she receives federal police briefings about the sensitive investigations.
"I will do everything I can to make sure that is maintained at arm's length from me and from government," she said.
