Polat,
Seems like you understand a little on abbreviations but:
dont should be don't and abbr abbr.
But to be brief rather than abbreviate, if you're thinking of studying in Australia have a read on Study Visas @
Students - Visas & Immigration and they will not use abbreviations too liberally there.
You will also not want to be too short in the money stakes either, and an exploration of the immigration site will allow you to see what requirements there are for permanent immigration and Citizenship.
There is also a work and holiday visa arrangement between Turkey and Australia -
Visa Options - Working Holiday - Visas & Immigration and that type of visa can be a great way for people from abroad to visit Australia rather than fall in love with an idea or an image.
