Kaka,
The only way you will find out for sure is to give them a phone call and ask.
I have heard in prior recruitments, that applicants have recieved notification via mail that their on hold time had unfortunatley ceased.
To be honest though, its not looking to go in your favour. Unfortunatley at this time, good ol' Qantas is in a bit of "shamozal" regarding recruitment and staff.
But go a head, just call them, they will be understanding, and more than happy to advise you of what is going on.
Keep applying to other airlines, and Goodluck..
