Hi dipti

there are some links to mba courses at these sites:

http://www.studyinsydney.com/mba-sydney.php
http://www.studyinmelbourne.com/mba-melbourne.php
http://www.studyinbrisbane.com/mba-brisbane.php

you can apply direct or through your local IDP office ( http://www.idp.com ) but make sure they do not give you bad advice so they get a personal benefit.

it is highly unlikely that you will get a scholarship. Have a look here: http://www.idp.com/scholarships/default.asp

good luck
