Intending to live in India after uni...

My name is Robin Kumar and starting university next year in Australia (Macquarie university) and will be ccompleting a
B of Actuarial studies with B of Applied Finance. After uni I intend to work for about 5 years in Australia and earn as much money as I can. Afterwards I wish to expatrite to India and live in either in Delhi or a major city in Uttar Pradesh.
In India my plan is to work a little at first and then start my own company (most likely an investment company).
So far that is my plan and what I want to know is if it is a good plan. My main concerns are buying a house, car etc in India, setting up a company (and making it successful) and getting a citizenship. If anyone can give me some pointers on my plan and concerns it will be appreciated.
Also am I right when I say that I will get a job because I have an Australian degree?

You are asking for alot. sounds good though. i wish u luck
