@ Mani - Drop me a PM when ready.
BTW - Australia "Does-NOT" have "The BEST" Education system in the world. It has around 36 Universities , majority of which are just a money making machine , they quite literally suck your blood away.
Quality Education is only provided by G-8 Universities , where a Bachelors [4 years] degree can cost a Pakistani student around 9 Million Rupees BUT if you have that money lying around , then don't go to Australia , you should rather go to the US , UK or Scandinavia.
Majority of Unis are dominated by Int Students , Australian youth is not a big fan of studying at unis. Research opportunities for Int Students are next to zero unless you are one of the .01% who would get a scholarship.
Education in Australia is "an Industry" - keep this in mind before you go.
Dont ! Go to agents , they know absolutely shitass about Education abroad , all they want is to get you a visa , put you on a plane and bang , they are happy with their commission , what happens to you isn't their "concern" anymore.
Thanks
