Oh wow thank you so much for all of this very informative and useful information. I will print off this chat trail and the PDF docs you so helpfully provided and get the ball rolling. You've made a lot of very interesting and insightful points, for which I am grateful. Getting $7,000 is going to be very hard but I'm hoping we can get that arranged and get the ball rolling asap.
Snifter - Can I just that it's best for me to wait for our 2 daughter's Aust citizenship and Aust passports to come through before my husband submits his application? I've pre-filled the form in online to already state that our daughters were Australian citizens and did plan on waiting for that proof to come through so I could attach it to the application. Would their (near future) Australian passport details be helpful as well?
Very good points made above were the fact that he'll need to be a PR before applying for a mortgage (something we were hoping to do as near to the start as possible after arriving), and also the point that the price is likely to increase again (a friend of mine went three years ago and it was only around $3,500 back then).
Thanks again, I'm starting to get my head around it more now. I'll be happy for any more advice anyone wants to give.
Edited to add: Another question...a few of you have said we can skip the temp resident one and go straight to PR....how do we do this? Sorry if I sound dim, it's just a lot to get my head around! Thank you.
