I am Charuhas from India . I want to register .com.au domain .I need immediate response , if anybody know the complete details let me know.
You can't. You need to be an Australian resident. Trying to bypass the rules would show a lack of respect.
You actually need to be an Australian business to register a .com.au domain (or .net.au) . You need to be able to provide a valid business number and also link to a valid business name. Sorry, it is pretty strict here for domain registrations. What about something with australia in it, but not with a .au tld?
You do not need to be an Australian citizen. Even not to have a company there. Virtual business is respected by all nations. Only thing is this that you business should be targeted to Australia.
