There was a bit written about the KNIL in the fourth Ally by Doug Hurst, and in "Allies is in a bind" by Jack Ford.
Not much, but it does drop a few clues about the immediate post war situation, where Australia sided with the republic and not their allies. A book about that peculiar position is "The return of the exiles" by Bennett. In there the KPM part is discussed too.
Besides, the vessels were not operated by the Australians, but by the US Army and the British Shipping Committee, either on bare-boat or full hire. The bare boat displaced crews ended up in camps in Australia. There wouldn't be many Australian record other than at the shipping agencies or the Australian corporate offices.
In my estimation, the cold relationship between Australia and the Dutch is probably the main reason why KPM does not get much attention.
