I'm planning to migrate in Feb 2013 to Perth and I've already my PR for few years now. I find the AUD130k per annum (with 5-6 years IT exp) quite unrealistic, and you should verify that with your hiring company.

Sorry guys but from July 1st 2012, skilled migration is closed. Now you can only apply thru EOI (Expression of Interest) where you have to pass the ELTS test, get your degree and work verified by ACS (Australian Computer Society) and your info will be in a database. This allows future employers to handpick the best to apply for PR (you will be invited). Otherwise, you have to just keep waiting.
