Ian and to a lesser extent Jim,
Yes, let the games begin. We all know the Project Management Process, but I like to cast the completed document or a music recording or a high dam finally producing electricity, what ever is presented to the public or an audience is as The Performance. All the work went on well before the big event.
The Performance would never happen without the input of a whole host of back up and support. Even Taylor Swift's performance would never take place without the guys who drive the 18-wheelers to the arenas. And George Jones never made a record without the song writer, a backing band and the record producer.
Net working options: May I suggest that you enlist anthropologists at the several superior universities in Australia. They have strong on-ground experience in the the study area, especially PNG. I worked there for a short while in the early 2000s and met a couple. Here's one of several good articles on PNG stone axes. Also, people who work on construction projects in the region can also provide access.

Nothing new here. I just like the Performance metaphor.
Best,
