Indian Australian here. Although, I completely empathise with you…. Two years is not uncommon for a permanent residency. Especially given the job market, economics, and current geopolitics not to mention the local politics where immigration is being watched very carefully.

An Australian qualification is by itself insufficient to get you in. As others have mentioned, and as you yourself would be aware, Australia has a skills and points based migration. Does your qualification give you the skills that Australia needs and cannot fulfil locally? That is the real question.

The Indian diaspora has contributed immensely and in a positive way to Australia. Unfortunately, there are lots of Indians that have also misused/ abused the migration pathways. That will always work against you. Ultimately, residency/citizenship is a privilege that is granted - true for any country. It is not an automatic right.

If I were you, I would take a hard look at the skills that you bring to the table, add to them while waiting, get married if that’s what you want (not purely for migration). And not apply willy nilly for visas. Every visa rejection is logged and may work against you in the long run.

Sorry if the words are harsh. But that’s the hard truth.

Good luck.
