I’m on a short tour in the Papua New Guinea Highlands
The PNG Highlands vary a lot. I’ve been in both the relatively modern Mount Hagen area and the rather wilder Hela province, near Tari.
Hela Province is in the State Department’s “Do Not Travel” category as “there is a heightened risk of civil unrest from tribal violence throughout the region”. I was with experienced guides and saw no trouble. But from chatting with the guides, it did come across as an area where it is still considered fairly normal to use violence to solve disputes. Afterwards, things can be damped down by paying compensation (in cash or pigs)
We passed an organized chanting/marching squad of men that I was told was collecting money from the local community to pay compensation for an inter-tribal killing. Looking closely, they were mostly carrying machetes and a couple were carrying rifles. Hmm. On the road we passed a couple of informal checkpoints which were quietly reviewing incoming vehicles. Fortunately no one seemed at all interested in a random foreign tourist.
Because Hela is a bit of a backwater, it actually preserves more of the old day-to-day lifestyle. For example, farming is handled entirely differently from the Mount Hagen area. So I’m glad I got to see both areas.
