Individual higher education providers set the minimum entrance requirement for admission into a place of study:
Each year the entrance requirements depend on the
- demand for the course of study
- number of places available.
Selection for an undergraduate place of study is generally based on a combination of your Year 12 performance and the subjects you completed in high school or college.
Students may also access higher education units through Open Universities Australia 
on an open access basis and with no education prerequisites. Students may then use the successful completion of such units as credit towards an award from a range of higher education providers.
