If a member of CASA staff alleged they were assaulted or stalked in the course of their duties and the CASA CEO was aware of the allegations, there would at least be internal correspondence and records about the allegations, even if only for WHS purposes. Public sector employees have a habit of making large compensation claims for far less serious things.
If it happened, why would the victims have any interest in not doing anything about it and how did the CEO find out?
And any CEO of a Commonwealth statutory authority with even a malfunctioning 'cover my arse' gene would refer the allegations, in writing, to police (probably the AFP in this case).
So if there are no records in CASA relating to any of the assaults or stalking of CASA personnel alleged by Carmody against Glen, I call bull**** on the allegations.
