Hey - I am from the ACT
(Well am from NSW, but living in ACT)
ACT social life is 'ok' - I think if you lived on campus you would be fine with the whole social life. If you lived away from campus, it would be hard to make friends etc as Canberra isn't that "exciting".
Oh- I am NOT at ANU, I am from UC - "the better one of the two" HAHAAHHAHAH One thing you will get in Canberra is the constant comparison of the 2 unis - its abit like comparing UNSW and USYD - no one ever wins a debate!
