Applying for another Student visa: Home Affairs updates its guidance
If you changed education provider after your Student visa was granted, or you need more than 12 months to finish and your provider has given you more time, you don't meet the course completion exemption. You must be outside Australia when you lodge and when the new visa is granted. Applying from outside does not stop you coming back to finish your course. A new visa is not guaranteed.
What it means: Check your dates and your provider before you plan anything. If you need to apply from outside Australia, time the trip so the grant happens while you're away.
