The eCoE is an acronym for the electronic Confirmation of Enrolment. Upon submitting your acceptance and payment deposit to your chosen institution, the institution will issue you an electronic letter (eCoE) to proceed with your student Visa application.
The eCoE discloses information such as the unique COE number (required for visa application), personal details, course name, course start and end date, tuition fees amount paid, OSHC provider, and others.
You cannot lodge a student Visa application without an eCoE. To apply for a new student Visa, you will also need a new eCoE.
