If you look under your NOC which is in the ministerial list and you perform the duties and the lead statement described there, then you may be eligible. I don't know how many years of experience one must have to be called managers.
If you do not have those duties, then you are ineligible and hence will get rejected most likely.
I am not sure if your wife can apply for FSW 3 after having living in canada in a visitor's visa. SOmeone else hopefully can answer that.
If your wife has experience in the ministerial list jobs, then she can apply for FSW 1.
If both of you are ineligible, then wait for CIU's reply to you from Sydney and depending on that, wait till Sep 2009 and apply under FSW 3 because then you don't need misterial list requirement (for FSW 3).
