Documents to sponsor brother

[immihelp]

Hello.

I am a US citizen and am planning to sponsor my brother who is an Australian citizen but born in India. Could you help me with what forms I would need to fill up beside I130? Also, is there a faster process for Australian citizens to get their visa number although his country of birth is India?

Thank you.
