Access to seven majors has been denied to new students in the University's of Wollongong's bachelor of arts degree.
Majors in gender, European, Asia-Pacific, war and society, media and cultural, Australian and post-colonial studies are no longer on offer.
Wollongong Undergraduate Students Association women's representative Claire Johnston said many students were upset these options were unavailable.
In an effort to provide students with some access to these units of study, Ms Johnston is busy organising free public lectures to be held in spaces such as the university's duckpond lawn.
"A lot of these are inter-disciplinary majors where arts students can take subjects from politics, history, sociology and other disciplines which gives them a well-rounded education," she said.
"Humanities are in the firing line at universities nationally, and students across Australia are launching campaigns against these cuts."
As women's representative for the student representative body, Ms Johnston is particularly concerned about the slashing of gender studies.
"Women's studies and gender studies were courses fought for by women in the '70s and '80s," she said.
"It's disappointing these gains made by students are being rolled back, with women's studies lost a couple of years ago and now gender studies.
"It's an important area given that women are still earning less money than men, and are still under-represented in the business world."
Ms Johnston said her plan to put on free weekly lectures was being met with enthusiasm.
"On campus we have an enthusiastic network of feminists and people interested in gender studies so I'm confident we will be able to offer regular lectures and workshops in this area," she said.
However, Dean of Arts Professor Wenche Ommundsen said one of the majors, media and cultural studies, had simply been changed to cultural studies and was still available.
Of the remaining six majors affected, she said the students had already "voted with their feet".
"We did an audit of enrolments in these interdisciplinary majors over the past five years and they were pathetically low," she said.
Prof Ommundsen said some of the majors (Australian, European and Asia-Pacific studies) would be retained as minors, while the majority of subjects within the majors were still available to arts students.
