If you live in Canberra, you have to develop your skills of making your own fun. Fortunately, that's pretty easy when you're living with 300 of your closest acquaintances. Besides, civic has a lot of clubs/bars, a movie cinema and lots of shops (including Aldi for cheap chocolate!) and nice to dodgy restaurants. It's close to the lake which is good to walk around, it's also close to Dickson, which has a Safeway, and very very close to Braddon which has McDonalds (all these things are walking distance). It's also really easy to catch a bus elsewhere. Also, everyone at college has a ton of legally acquired movies and TV shows on their computers. Oh, and you'll also probably have to do work...
A major drawback is that everything closes pretty early compared to Melbourne and Sydney, except on Fridays (late night shopping).
