I haven't done it but I looked in to it. TAFE as usually cheaper, expecially with their government training places they have going at the moment, you ony pay for materials which is about $50-60 a module, they are VERY cheap. That's in QLD but I think it's a federal government initiative. In my area they are $800 at TAFE. You do need to have your Diploma though, or at least be able to go through the RPL process
