Around day 8 of the jambo I spent half the day on an adventure trail with an Australian scoutmaster. His Australian troop had been augmented with a smaller Dutch contingent which had girl members. He said he saw the girls taking their birth control pills during breakfast. He also said that while on an earlier visit to the jambo infirmary (field hospital) he was told by attending staff that up to that point during the jambo there had been ~40 requests by girl participants for pregnancy tests and that ~ half were positive.
Like BSA, I presumed most, if not all nations (there were 84 represented at the jambo with an overall total of 14,434 scouts officially registered), had troops touring Australia and New Zealand for a week+ before arriving for the start of the jambo. Given the test method of that time, it was certain that these girls had already been impregnated before starting on their world tour.
The Australian scoutmaster also said that the infirmary had a supply of condoms available to scouts if they asked for them, but the Scout Association of Australia (the host organization for this jambo) did not advertise this fact to the jambo participants. The World Organization of the Scout Movement retains oversight of all world jambos.
Almost forgot. There was a beer garden on the jambo grounds that was restricted for adult scouters only (don't remember if the minimum age was 18 or 21).
Oh, dear God. Please help the youth of this world.
