Two thoughts about this to keep in mind:
1) Just what in the hell did anyone think the Army hierarchy was going to say about this. To the public and their political bosses they were "embarrassed and shocked". In private, they probably were holding their sides and remembering what they had done years ago, but were lucky enough to not get caught.....and of course the men will be punished. They should be punished, but for being stupid enough to do it in a place like that AND getting caught.
2) If that had happened during some war that Australia was involved in and they needed all the "warm, experienced bodies" they could get, then those guys could've hung something else out those doors and they would have just shipped them back to the "front".
MORAL: on he first count, don't believe everything you read and on the second count......everything is relative. 😀
