Some places have application tests before giving you the form, but basically first come first served unless application course so if you get there at 1:15pm and 20 people in front of you in line you might be on waiting list.
If you have centrelink paying for our course (1 free a year) bring some form of centrelink ID to show the centrelink people who can also assist you.
line up for the faculty of choice wait in line, pick up forms and info ask any questions, you should get at least 2 to 3 pieces of paper, enrolment form, Rights and responsibilities of Students, centrelink exemption. Some places give you more like course info on starting times or campus info etc, just depends on the campus and faculty.
Once you have your form fill it out bring it back to be signed by the teacher and then take to front office to be processed. If centrelink exemption get them to stamp and sign it, if not bring an eftpos or credit card because TAFE is on a cash minimisation directive so most won't accept it.
