Are you transferring from the Sunway campus?
If so, can go to student center and ask for application forms.
Then just fill in the form and pass back to the staffs at the student center along with your results.
Do take note that the requirements (base on results) to transfer to Clayton and Caufield campus are a little stricter than the other campuses in Aussie.
For more information you can actually ask the staffs at student center ^^; they offer a lot of help when I am applying for mine some years back.
Hope that helps~
