I don't think any poster could trash Jake McGoldrick any better than he has trashed himself.
The OP's link is to an AAT case where the truth is sought out, as in every properly-constituted court of law - and the AAT is a very large and important part of the Australian legal system.
The information revealed in that AAT case suggests that everything the OP has stated is largely true.
One always has to harbour some suspicion about anyone who claims they were "bullied" or "harrassed" in the military.
In groups such as the military, it doesn't take long for tossers to be identified and therefore become the target of those with perception and understanding that the tosser is not what he regularly claims to be.
Granted, there are people in the military who are abusive and domineering and who seek out weaker personalities to degrade them. I'm not sure that Jake McGoldrick was such a victim of those abusive personalties.
