For anyone interested in the early days of European exploration of New Guinea, this three-in-one documentary series filmed over a ten-year period - "First Contact" (1983), followed by Joe Leahy’s "Neighbours" (1989) and "Black Harvest" (1992), - offers footage of exceptional quality considering that it is twenty to thirty years old.
Youtube has some short clips:
First Contact
Black Harvest
First Contact - The Day the Plane Came

Occasionally, the full set of DVDs is on sale at ebay at around a hundred dollars, not an unreasonable price considering its rarity.
The DVDs as well as the book are also available direct from the producers - click here.
