Smiles has given you a good head start on information for Australian colleges. FYI… short term diploma courses in Australia are offered by the colleges, not uni. TAFE is public/government college, and there are private as well. The course is usually categorised as Vocational Course/Study.

I suggest you to go to the Dept. of Education, Science and Training website (http://cricos.dest.gov.au) or IDP Education Australia (www.idp.edu.au) online database rather than Googling (or Yahoo-ing). It will give the list of institutions that are able to offer courses to international students who wants to continue their study in Australia. The info abt fees and requirements are available from the colleges’ websites. Please make sure that the information you are accessing are the one for International Students. Once decided on the college, fill in the international students application form and send it together with certified copy of your academic transcripts. Depending on your country of origin, you may also need to submit an IELTS test results as proof of your English proficiency.

Hope this helps. E-mail me at mikegun(at)studentfirst.com.au if you have any more questions abt study in Australia. Good luck on your study )

The TAFE institutions will have an international student office on every main campus, so retry googling. Hope you have more success this time.

All the best.
