The first answer would be that if you asked about your file you probably would get a “we neither confirm nor deny” answer from us if it was part of the operational holdings. That wouldn't be the end of it, because our system is set up so that under section 41 of our act, any person can complain about any act or thing that they believe the service has done. They can complain to SIRC about it. SIRC will review it, and they will give you an answer. It may not contain all of the details, and it may not be the answer you like, but you will be assured that there is someone who will have looked at it and will have had complete access to all of the records.
In some ways that's my understanding of what the Privacy Commissioner is supposed to do. Under section 34 of the Privacy Act,
...the Privacy Commissioner may...examine any information recorded in any form under the control of a government institution...and no information...may be withheld....
