Not Fast or Quick
They took two days to tell me that my Police Check is gonna have to go over a manual review and that this is will take 7 to 15 business days to get ready. Its slower than AFP.
On the website they say 80% of the checks get back within 2 or 3 business days. On the email they sent to me they have pointed this happens in around 30% of all police checks in Australia.
For me sounds like they are just fooling their customers.
