A 24-hour support line for university sexual assault victims is being launched ahead of the release of a national report on campus abuse.

Universities Australia is launching the interim phone line the day before a survey looking into the scale of sexual assault and harassment among students is made public by the Australian Human Rights Commission on Tuesday.

ANU vice chancellor Brian Schmidt expects the results to prompt an influx of reports for those who have never shared their own experiences with sexual abuse, the ABC reported.

In September, a student made claims Sydney University (pictured) was not supportive and even suspended her from her course after her studies fell apart as a result of sexual abuse

He said data may be harrowing for students who have been impacted by sexual abuse and warns it will likely be confronting.

'The results will be shocking, and we should be shocked,' he said.

Despite the results revealing insight that may be distressing students may likely use the new information as a prompt to speak out.

'We know the release of the survey is likely to see a greater number of students seeking counselling support,' Universities Australia chief executive Belinda Robinson said on Monday.

'We expect the results will be challenging for everyone. But particularly so for students, victims and survivors who have told their stories as part of this important project.'

Another university student, Sarah, said she was also raped on campus

In October last year three young women shared their stories of how they were allegedly raped at Australian universities - two when they were just 18.

They were some of 575 students who were sexually assaulted on campus in the past five years, with only six alleged perpetrators expelled.

The previous month, two women who were raped on their university campus shared insight into their horrific experiences as they called for more support from the universities.

University of Sydney student Katie Thorburn FIRST made a report after being raped at a party in 2015.

Another university student, Sarah, said she was also raped on campus.

Ms Thorburn said Sydney University was not supportive and even suspended her from her course after her studies fell apart as a result of the attack.

The 1800 572 224 support line will operate from 9am on Monday until November 30 in addition to universities' existing phone and face-to-face counselling services.

All of Australia's 39 universities took part in the AHRC's report being released on Tuesday.

'The results will help us to combat sexual harassment and sexual assault and to improve support for students,' Ms Robinson said.

Former commission president Gillian Triggs last year said she hoped the data would shine a light on disturbing initiation rituals, the experience of international students, and the rates of sexual assaults at universities compared to wider communities.
