I fully agree with verystormy, the experience through 457 from 2013 onwards is not good.
Before reaching here the agency was saying about MOON and GOLD is in our hands.
Once we reached here then only we came to know the reality. Now the HR is not ready to talk. They says 457 visa is for 4 years. That's it. Above all I need to pay school fees both private and public in WA, NSW and Canberra.
