A couple of points, on the run:
- the current Statement of Expectations is largely irrelevant to your circumstances - perhaps link to both the previous and current one? (Though I can't find a copy of the old one, but only searched briefly.)
- the APS Code of Conduct is not relevant to CASA (and I can't find a copy of CASA's Code of Conduct on its website, but only searched briefly).
Will try to comment more when I can digest.
(I doubt whether too many recipients will be reading your corro on ANZAC Day. Perhaps send at 9AM on 26 April?)
