MORE than 450 people are expected to gather at Adelaide University Friday to take a stand against homophobia.

The gathering was sparked by an incident earlier this week in which faeces were placed in a microwave of the campus' Rainbow Room - a room described as a safe place for the university's gay and lesbian community.

The event: "Urgent Response - Say No to Homophobia at Adelaide Uni!" was created by the Adelaide University Student Representative Council and promoted on Facebook.

More than 460 Facebook followers have said they will attend the event at the Cloisters at noon.

The Student Representative Council condemned the act on the event's Facebook page and considers it a homophobic attack.

"We students of the University of Adelaide condemn such homophobic behaviour and we will not accept it at our university," the Facebook page read.

"We call on queer people and allies to come together because we will not let these behaviours that are designed to make students feel unwelcome, scared, or disgusted, make anyone feel unwelcome, scared, or disgusted - instead they will unite us in anger, solidarity and support."
