They can't provide specifics only ranges. In Division 6, section 317ZF, Unauthorized Disclosure of Information, section 3) subsection 13) a person forced to do one of these TAN/TCN/TCR things can release a count of how many of these TAN/TCN/TCR things. BUT Note: This subsection authorises the disclosure of aggregate statistical information. That information cannot be broken down (a) by agency; or (b) in any other way.

So Division 6, section 317ZF (3) (13) is the ONLY way someone can tell the world what is happening.
