Does anybody know when the 'reapply in 12 months' starts from? When you first applied or when you got told thanks but no thanks...
If you did not go to an Assessment Centre (i.e. "interview") in Sydney then the 12 months applies from the date on which applications closed.
If you attended an Assessment Centre then the twelve months commenced from a later date which I believe was the date on which you were notified that you had been unsuccessful.
By all means though, do not take my word for it; email them!
