I can tell you that at UNSW, the student organisation has a Queer department who deal with issues that GLBT deal with. An offshoot of this is Queerspace which is a 'safe zone' where people who identify this way can hang out and feel free from discrimination or harassment. The Queer department also run plenty of activities and workshops, for GLBT people and people who are interested in learning more.
I am sure all universities have a division like this, and from what I have heard they are all lovely friendly people who are easy to talk to and deal with. If you are feeling a bit shy I am sure they will have an email address where you can ask questions.
