I did a course through TAFE by distance education. Its called OTEN in NSW. You can do heaps of courses through them by distance education. For some courses they send you booklets of study materials and worksheet, and some courses have everything online. You can study with them from anywhere in Australia, although some courses have a special workshop where you actually have to go in person for a week or so. I'm sure they have it in other states though through the TAFEs in the other states.
