“the Indonesian officer went to the academy’s head office to complain and reportedly found a play on words referencing Pancasila, but ending the word with “gila” which means crazy or mad in Indonesian” — I doubt the average English speaking Australian soldier would know enough Indonesian to understand this, and even if this alleged gibe was directed to Australian officers who may know some Indonesian, I have doubts that they would be joking like this in Indonesian. It must have been a joke directed by and/or to Indonesians. I think we are not getting the whole story here.
Indonesian is a common language taught in Australian schools - they are one of our nearest geographical neighbours. It’s really not uncommon for ADF personnel to speak Bahasa Indonesia.
