Immigrating to Australia with Parents
Hi Ram and sorry about the delay (technical issues with our forums) :|
There are a couple of options available for you.
A Temporary parents visa which enables your parents to live in Australia for 5 years at a time:
Or the general parent's visa which will allow your parents to stay in Australia permanently though there are a number of additional conditions associated with it (balance of family living in Australia etc).
I hope this helps
