What a bunch of memories! I remember being told about the guys in the tower racing down as an Air North (I think) Chieftan was taxying past on Alpha with a bunch of tourists on board who'd just been out Kakadu way. The boys, apparently, had made up score-cards, like they have at the diving at the Olyimpics. They raised scores, right on the edge of the taxyway, in succession, of 6 out of 10, 7 and 3 related to the landing. When asked by the tourists "what was that all about?' the pilot, who went on to fly with TAA, said "they're my mates and they always update me on the cricket score."
I think the guy was known as "Maddo", but can't be sure.
