You can apply to extend your Confirmation of Enrolment (CoE) using the Confirmation of Enrolment Extension form.
Complete sections 1 - 3 of the form and return it, along with supporting documentation and statement explaining why you need to extend your CoE.
Email the form to U.Connect@utas.edu.au. If approved, you will be sent your new CoE via email.
It is important to note that it can only be extended if you have compassionate and compelling reasons.
You will then need to contact the Department of Home Affairs for advice on how to extend your Student visa.
