To apply for a Student Visa you will require a Confirmation of Enrolment (CoE), a document that is issued by the education provider (in this case Hillsong College). A CoE can only be issued after you have been accepted into Hillsong College and the minimum fee payment has been made. Once the CoE is received, you will need to apply for a Student Visa by contacting DIBP or your closest Australian Embassy (see https://www.border.gov.au). To apply for a Student Visa online please visit www.border.gov.au/students. Student Visa applications can take anywhere from a few days to 3 months to be processed. Please note that you cannot submit a Student Visa application more than 90 days prior to the enrolment date of your chosen education provider.
If you have school-aged children, you will need to provide evidence that you are able to support them whilst you are in Australia. You will also need to provide evidence that they have been enrolled in either public or private schooling in Australia before your arrival.
For further information about Student Visas please contact DIBP (www.border.gov.au) or your closest Australian Embassy.
