Multi - IR from Australia required or no?

1 To get MULTI - IR in Australia or not?: For Indian Instrument rating, you do not need an Instrument rating from Australia to convert. If you plan, not to get an Instrument rating from Australia, then you would need to provide enough evidence of all the checks satisfactorily done. I'll guide you with the paper work later.
