Hi Kaye
Cant help that much with your questions although the bit about your friends validating theirs before July 1st is a bit baffling. Our visa was granted in Apr and our pink slip in our passport clearly gives us the date which we need to validate by and the date by which we have to have moved there by (july 2012) so l would be very surprised if that was changed.
My understanding (and it is only that

) is that you are bound by the visa stipulations relative to when your visa was received at the DIMIA office therfore yours would be pre September. I too thought it was only the citizenship bit that was changing which will apply to us as we didnt get out to validate before July 1st (gutted about that as I would quite like to be an assie citizen before the 2012 olympics cos would be sooo embarrassed bout the potential shambles tehe) Joking aside also have no idea if that rule has yet been put in place either!
am sure your visa will come through soon now. Was told that if they have asked for your pc's and meds then provided there is nothing wrong there you are in! as they approve all the other bits before asking you to undertake these. (Just hope l've not been told a load of twaddle

)
