It might be. I just had a look around for a citation and didn't find much. However I do recall a law student finding something in the university by-laws about it (however that shouldn't overrule state law... unless it does). I found http://www.austlii.edu.au/au/journals/UWSLawRw/2002/3.html but the University of Melbourne seems to be victorian crown land (since at least 2000 http://www.legislation.vic.gov.au/domino/Web_Notes/LDMS/PubP...) rather than commonwealth crown land. I don't know enough about property and title in Victoria to make a call here.
