I didn't thought :/
I just did it to myself to see what others could find and who I might know in mech because I had no friends :(
But yeah the best you can do is, name, zID, timetable, email address, degree and some other misc data so not that bad
I did last semester. UNSW is not very safe with handling personal data. All you had to do was type "finger <target> " and it gives you everything lol
My access was revoked this semester :/
