Do I have to wait till the end of the year to apply to uni and start studying in the new year?

Midyear entry (Semester 2), starting in July, is available for most Flinders University undergraduate and postgraduate courses.
Applications through SATAC (South Australia Tertiary Admissions Centre) open in early August of each year for entry into the following academic year. You can apply for courses available in semester 1 and mid year from early August. Most courses available for mid year entry close in June to commence in July the same year.
