I go to AIE Melbourne doing Programming. There is no specifically game design course on offer. I did programming at
QANTM (w SAE) until I flunked out. Qantm is more like a uni, in terms of you must drive your own learning whereas AIE is more of a TAFE and lead you through practical and hands on tutorials and pretty frequent assessments. I much prefer AIE.
I had a friend that did programming at Swinburne and he said it was shit, which is why he left and went to Qantm. That friend graduated and is now working for a stock company iirc. Take that with a grain of salt though, as it's from a friend.
Anyway, I think AIE is pretty fucking great for programming, it seems pretty great in terms of the 3D modelling and screen stuff too, but I have no experience with those so yeah. If you apply for midyear at AIE you'll be there with me!
