I do not offer any summer internships, I am sorry. If you apply anyway, I will most likely ignore your email as for one I don't have a position anyway, and also because it shows that you did not read my announcements (as explained in my page on advice for applications).
There are ANU programs for Internships, especially for students from India:

The deadlines for this program have already passed, but the page might help you to apply within time for another semester or year.
I also advice to check out my page on other opportunities as it might help you find other supervisors from the ANU or other Universities.
