If its not too late look into help from Centrelink. Im studying similar stuff at uni (3 years to begin with), but a little more game centric (c/c++,flash/actionscript, 3dsmax, modding unreal engne,ai programming, etc.) and normally the fees werent dissimilar to what you've mentioned, but with some government education assistances (available to a good portion of the population I'd imagine) I managed to get in for less than 10% of the "advertised" prices. Im in a different state to you (Vic.), so things may be a little different, but it's probably worth looking into. Now in regards to the studying itself if it's anything like what Im doing it get pretty heavy quickly, and only the people that really want to be there seem to stick around for more than maybe 3 months or so. Having said this though if you'll get skills and/or knowledge (plus paper qualifications are useful sometimes) that you'd like to be using in your life then go for it, life's too short not to at least have a crack at things you want :-)
