You should arrive in Australia before your course start date so that you can attend Orientation events. In this case, you must ensure that your health cover commences prior to your arrival in Australia.
Your OSHC must cover the dates of your student visa. So you’ll need to include additional time after your course completion date.
According to Department of Home Affairs requirements, if your course is longer than 10 months and finishes at the end of the Australian academic year (November or December), you should have OSHC until 15 March of the following year.
Example: If your course completion date (in your Offer Letter and Confirmation of Enrolment) is in December 2026, your OSHC must cover you until 15 March 2027.
