Christmas Island sported two Austers used for DDT spraying, c/s's Flit 1 and Flit 2, in the early 60's. 48 Squadron had a rotating detachment of two Hastings at Christmas Island to provide airlift capacity to/from Hickam AFB, some 1000 miles north, and ASR cover for that (no-one else flew the route and the Navs would get their own winds back at met briefing for the return flight some days later).
