I don't have the bond paperwork handy so not sure.
But I do know that the cost of moving my family here and everything involved with it, like paying for residency (immigration attorney etc) is a good amount of money. The money (percentage) I would have to pay back after 1-5 years changes each year as I stay. I don't plan on leaving Australia so the bond really does not mean much to me as I will not break it and have to pay any money back.
Good luck to everyone, I start my training in a little over a week.
My family is here on the central coast all settled and we move into our house tomorrow.
