The short answer to this is yes. However, entry into many courses will be very competitive. See the section below about having a tertiary record. If you attended a university or another tertiary institution, you will be considered for admission on the basis of your secondary and tertiary studies. These studies must be at Associate Diploma, Diploma or Bachelor's degree level, and you must have completed the equivalent of one year's full-time study.
Entry is competitive.
In many cases, credit will be granted automatically for courses considered equivalent to those in the Faculty to which you are applying. In other cases, detailed information may be needed on course content before a decision can be made. It's important to supply course handbook descriptions when you first contact the Faculty. I completed my schooling overseas. You're strongly encouraged to take a relevant bridging course if you haven't got the required assumed knowlege in a program.
