You may study and live in Australia with the University of Sydney taking responsibility for your welfare arrangements as a condition of your student visa. .

You will be required to use University approved service provider companies for your accommodation and welfare arrangements. The University will not approve arrangements with any other service providers or arrangements with family members. 

Approved providers of welfare and accommodation are regularly added and updated on the Under 18 Information webpage

Once you have signed up with an appropriate welfare and accommodation provider the University will issue a Confirmation of Appropriate Accommodation and Welfare (CAAW) letter along with your eCOE. You may then apply for a student visa.
