While QANTM may be good, there are better options, though costly, and you need a portfolio to enter.
I cannot recall the name of the school (I\'ll ask my friend and get back to you), but there are two, one in Melbourne and one in Canberra. They are solely designed for game production/creation/design etc.
I myself was interested in applying, but I need to create a profile. Currently I am at university doing a Bachelor of Psychology, and it interests me, so game design may be a thing of the past.
Search around before committing yourself, and you may find something better suited. Unless of course you have your heart set on QANTM or you don\'t want to leave QLD.
My advice, get a copy (legitimate) of 3dsMax 6 or even 7. You like modelling, that is the best available. That is all I can help you with.
