Yes Robboat you are rite,
But this is unfair for those who have already lodge their application before 1 july 2013. they are still under the changed rules.
but this is unfair for migration agent too who advised to their client on first step of their application " No need of the IELTS in 457 if you want to Lodge your file as a manager".
May be client will keep this image in their mind, Migration was lying to make money.
at this step, Its very hard for them to convenience their client that rules had changed, you need to follow new rules, Alot questions from their sides which a migration agent have no answer.
