I disagree about the Pacific nations. Chinese bases on Solomons, Fiji etc isn't a good look.
but you're right, Indo is very important and unfortunately Aussies don't seem to see it as either a place to avoid (eww Jakarta's disgusting) or a place to go and get paralytic and turn get beaten up by security (Kuta, Bali).
I've also spent a little bit of time in Indonesia and have had a little glimpse of what you mentioned. it's not pretty. best to move on like you did and avoid the confrontation.
