TAFE courses offer certificates, diploma and associate diploma. These credentials are for tradesman like fitter, turner, electrician, plumber, draftsman, air conditioning mechanic etc.
The foreign trade qualifications need to be assessed by Australian authorities to establish their equivalency to the Australian qualifications. Most people planning to migrate to Australia often take courses from them, especially the courses that are still on the eligible skilled occupations.
