The Unique Student Identifier (USI) is an Australian reference number that is uniquely yours and stays with you for life. It provides you access to a USI online account with records of training from all providers in Australia. The USI makes it easier to find, collate and authenticate your educational attainments, and to ensure that your records are intact.
It is essential that students enrolling in Tertiary Courses provide their USI, as required by Australian Government regulations. It is not possible to fully enrol or be issued with attained qualifications without your USI.
If you do not already have a USI you can easily apply for one at https://www.usi.gov.au/students
Overseas students can use their passport to authenticate their identity when applying for their USI.
