@jojit05 when I graduated from my engineering I've applied for PR but unfortunately I haven't met all the qualifications. To be honest guys it is not easy to get PR here even you finished 2 years study here in oz. I will give you some idea.
after 2 years study you are eligible to apply for 485 visa which is Graduate Skilled Visa(temp visa only for 18months) this is the time na mkahanap ka ng full time job or sponsorship kung swertehin ka.
there is new government proposal to DIAC and might be implemented early 2013 na if you have enrolled in any Australian universities on or after March 2012 you are eligible to have 2 years post working visa if you have finished bachelor and then 3 years kapg Masteral.
