The process of Australian student visa begins with the application for admission in university. Then an offer letter would be sent, based on which you need to complete the Electronic Confirmation of Enrolment (eCoE) process. It is always a good idea to wait till you get the guidance from the university to obtain a eCoE. They provide information regarding how to apply and what documents are required to enclose with the application. To complete the process, you have to make payment of tuition and other fees (Overseas Student Health Cover and application fee, if any).
