If you go abroad for studies, make sure you somehow settle there because that cost is very difficult to recover by working in SL. At the same time, settling in a foreign country is quite a challenge as the rules changed radically after the GFC. For e.g until the beginning of 2010, every international student was eligible for PR, simply by studying in Aus for just 2 years but they completely changed the system this year to a employer driven system and that's why lots and lots of students had to return home empty handed without PR.
Don't take this personally but unfortunately you belong to that 95% of our population who believe that success/ richness in life can be only achieved through studies and working under someone for those low wages in SL. I responsibly say that because if another kid in your age with a good business plan has access to even half of that Rs. 2,400,000, he would make sure that 10 people will work under him by the time he becomes 25
. Bottom line is eventually you too would work under someone like that, with your expensive Aussie degree
