back on the topic of breadth - there are endless options available. Just about all Arts subjects are offered as breadth, so lots and lots of first years take Global Politics or Australian Politics as breadth. It gives you a nice intro into how your political system works and the big issues in the international world today. There are also History subjects, English language, languages, Cinema studies, Classics, Cultural Studies, Sociology, Criminology, Archeology, Astronomy etc etc.
I am an Arts student, so my breadth had to be outside arts - I did Introductory Microeconomics and Introductory Macroeconomics from the Commerce faculty last year, absolutely loved them (didn't know anything about economics previously and hadn't done it in VCE) and now I am doing an Economics Major.
As someone mentioned before, if you just want a chillout subject, music offers African Drumming, Beginners Guitar etc etc which you basically pass just by turning up to 75% of the classes/rehearsals.
The only thing I would recommend is making sure you choose subjects which will allow you to do the ones you want in second and third year - if you just pick randomly in first year, you will get to later years and realise you don't have the prereqs to do the breadth you want. So if you know there is an area in which you want to do all your breadth subjects for your whole 3 years, make sure you know which subjects from that area you have to take in first year to allow you to take more in second and third year.
Have fun with breadth - it's a chance to try something new and like me, you might find something you really like!
