In 2004, ASIO "re-issued" all ASICs.
Not a physical re-issue, but a second look at all holders, to ensure no baddies had slipped through.
No great fanfare, but it did take slightly longer than planned; there were 10,000 + more checks to do than planned. Over 70,000 total, in fact.
No adverse findings, although several investigations were undertaken.
The point to this?
Food for thought and an interesting comparison to the current debacle.
