This is a RAAF problem, always has been
I disagree. As outlined in the report AsA did not provide compromised separation recovery training until they experienced their own separation breakdown approximately 12 months earlier.
Additionally, while not mentioned in the report, the Defence compromised separation recovery training was actually under development at the time of the incident in question. This has since been implemented, as it was always going to be, but it is unfortunate that this incident occurred in the interim. As anyone who has worked in training development would know there are often significant lead times involved with changing courses.
