I can't talk so much about how it's evolved over time, but in describing it today, I feel quite comfortable with it, to be honest with you.
We actively communicate with employees that they can raise concerns they have with their manager. We say that's probably the first route to take, but then we have an internal process, as I mentioned earlier, which is anonymous. People can have a safe space to raise concerns if they see something happening that they don't think is appropriate. Finally, there's the overview of the Public Sector Integrity Commissioner. Cases can go to her.
We have had a few that have gone to the Public Sector Integrity Commissioner, but to my memory, not very many reached her. This could say our internal systems are working well, but I wouldn't say that with total confidence.
I feel very comfortable that what we have is an open regime that people understand. Hopefully, they feel comfortable raising internally, in that anonymous framework, anything they see going on that's inappropriate.
