The posters, which were in support of Holocaust denying author David Irving, were found on April 21.

The University of Canberra has become the latest target for Holocaust deniers, after similar posters were also discovered at the Australian National University, Monash and Melbourne universities in Victoria, as well as the University of Sydney in recent days.

At ANU, many of the posters were placed on communal noticeboards and in foyers of buildings, as well as next to residential colleges and on the windscreens of students' cars.

Both ACT universities have condemned the incident and said they would determine those responsible.

"Distribution of material found to be offensive or inappropriate will not be tolerated and will be immediately removed from our campus," a University of Canberra spokeswoman said.

"The University of Canberra is committed to providing a respectful, safe and inclusive campus and is outraged by the content contained in the posters."

An ANU spokesman said the university was "appalled" by the distribution of the materials and those responsible would face disciplinary action if they were a staff member or student.

All of the posters contained a link to a website run by the group Chemtrails Geelong, which features a 4700 word article disputing the existence of gas chambers.

ACT Jewish Students Society president Eli Madar said it was concerning the incident occurred so close to Holocaust Memorial Week.

"Personally, I found it particularly striking ... that there are individuals passionate enough about spreading blatant falsehoods that they target a vulnerable minority within university students," she said.

"It was incredibly disheartening to face this kind of discrimination not only throughout the wider university campus, but also on people's physical doorsteps.

"I think the best thing universities can do to prevent these kinds of incidents on campus is to encourage education and the awareness of the Holocaust more broadly, through not only commemorations, but public forums, discussions and the continued education of students who study such topics."

The incident at both Canberra universities comes just months after similar flyers were distributed at ANU by the same group in August 2016.

President of ANU's student association James Connolly said it was concerning the material was being displayed around the campus.

"It's inherently intolerant and pedalling an agenda of anti-Semitism," he said.

"ANU as a university is committed to being inclusive to people of all faiths."
