A Confirmation of Enrolment (eCOE) for international students seeking a student visa can only be issued from the government PRISMS system.
Information about other forms of enrolment evidence (e.g. for Centrelink or AHPRA) can be found here.
An eCOE is only used for international students applying for a Student Visa.
After you have returned your signed International Student Agreement and paid for your first semester fees, an eCOE will be issued and emailed to you. You should keep your eCOE somewhere safe for your ongoing records even after you finish your studies. If you do lose it or need another copy, please contact education@cairnmillar.edu.au
