A Unique Student Identifier (USI) is a unique number issued to each student by the government upon application. It only takes 5 minutes to apply, and once you create a USI, you have it for life.
All students must have a USI in order to enrol. You will also need a USI in order to receive commonwealth financial assistance, as well as to obtain your qualification.
If you have undertaken any vocational education or training since 2015, you may already have a USI.
