Sometimes you have to face it that you might not get everything you want in life. You have to make choices that may bring good or bad to yourself, so think carefully.
Since you are from MMU, let me tell you a little story. There are 2 guys, A and B which came from MMU and took a degree in IT. After graduate both went seperate ways.
Guy A did what a lot of people did, got a job after graduation and earn a normal living. Now, guy A have almost finish paying his car and is buying a house now. Earning around 5-6k.
Guy B went on to
Melbourne University in Aussie on parent's account after MMU (CGPA>3.8).
Fees costs around ~10-15k AUD for the 1 year Masters course. Guy B graduated a year later and had to wait a
few months to get a PR. After bumming around some part time jobs, Guy B did get a good IT job earning 2-3k AUD. However, cost of living was high, and Guy B didn't get a chance to save a lot. Guy B plans to come back after making more money but as time goes on, Guy B decided to settle down in Aussie instead.
Guy C went to Aussie on parent's account. After graduation, could not secure any job. After 6 months, all Guy C's money and his parents money dried out. In the end, Guy C came back broke and made his whole family suffer a lot of monetary loss.
You could be either guys. However, if you do not have financial backing from family or yourself, it is very risky to do so. It's not easy to get a scholarship, especially if you are not the cream of the crop. If you get a bank loan, interest is high and you need gurantors or collateral. What if you can't get a job in Aussie? How long can you live on your scholarship money (if you do manage to get one) in Aussie?
I'm not trying to pour cold water, but please think carefully before you make any decision. If you do manage to secure a way to go, do share it with everyone.
It is at least AUD 20k on tuition fees alone at the University of Melbourne.
To get a PR, you need to have points and $. As you already know, the australian government is reviewing the whole system which means tougher conditions and all.
