Well, after what seems like a lifetime I finally got the call this morning! I quickly rushed over to the migration lawyer and picked up the paperwork (postal strike, so couldn't wait!) and I am just about to send off the passport.
Just one piece of info (which you all may know) if you are on the SIR visa you no longer have to live in the area that has sponsored you. I have been a given a list of postcodes which seem to include everywhere apart from the major cities and metro areas. I am bit frustrated by this as my heart was always set on Cairns (where I have friends and I know it really well) but having invested time/money/energy in going to Adelaide (and liking it) I am sticking to my plans and can't wait to get there!!! ( I also have some really good friends there now, which is great)
At least I now know I have some choices!
Thanks to everyone who has replied to my posts, it has been really good to hear from everyone. :)
