QANTM and QUT are the 2 top In my opinion. I did programming at QANTM in 06-07 and it was fantastic as most of what I learnt was practical useful information and all the work we did was actually creating software rather than just studying theory / algorithms. Also got job offers at Halfbrick, Krome and Firemint upon graduating.

Honestly I haven't met (or even heard of) any good coders from Griffith and UQ is as said good for most disciplines but not sure about IT.
