Yes, that is why I am confused. I certainly met the requirement of Australia study, but I am not sure whether I am eligible for regional study point. Someone told me I am not, but when I called the immigration department, a nice lady told me that as long as I studied in Adelaide for 2 years, it is ok. I actually hope to get a written confirmation (either eligible or ineligible) since I don't want to get refused because of inaccurate information. But unfortunately I couldn't find any email address.
