Hi,
I might be able to give some information. I have a friend who used cross-credits (although not from India).
For AUT for example, you can apply to have credits transferred. My friend was allowed 'skipping' the first semester, which are core papers.
So, if accepted, you can start in Semester 2 of year one (study 3 1/2 years instead of 4). I think that's the maximum they permit.
Recognition of Prior Learning & Cross Credits - AUT

Best to enquire directly.

Cheers,
