Under legislation, the University is not permitted to provide advice about migration or visas. Only the Department of Immigration and Citizenship or a Registered Migration Agent is permitted to do so.
You can search for a Registered Migration Agent on the MARA website.
The International Student Quality and Compliance website has a visa section that provides links to DIAC information.
Your campus International Student Adviser can provide you with general advice about where to find relevant migration and visa information.
