I flew Dustoff out of Quang Tri and many of the ARVN battalions had Australian advisors--I remember Alfie Gee, and Snowy. Also remember flying out to the Melbourne (??) an Aussie ship off the coast, to deliver their mail via our rescue hoist. The deal-clincher was that when the hoist came back up, it had a couple of cases of Foster's or XXXX.
The Aussies also made a modification to the standard medical evacuation request--added a line. If line 10 (??) or the last line was "Yes" it meant they were at the pickup site of the patient, and we had to go to the club, get a beer and two cokes, put it in a plastic bag with ice, and when we landed in the LZ, the left-seat pilot just held it out the side window. All you would see would be a green streak out of the bush, grab the bag, and back into the bush. Woe be to the pilot that didn't comply--unless he could prove he received the mission while airborne and didn't have the opportunity to comply.
Another rule they invoked on me several times--"Dustoff 707, the LZ is hot and you're not coming in until we get it settled down a bit." They would tell you face-to-face that "they aren't worth it" (the ARVNS).
They also had this neat habit of carrying around a template of a "skippy" or a kangaroo--about 10" long, and a can of the yellow anti-corrosion paint we used on our birds. Those yellow skippies appeared on many if not all of our aircraft, which drove my commander nuts-o. solaf
