This might be a long shot, but I'm trying to jog my memory regarding the route taken to fly LDN - BNE on the Comet service in October 1964.
I remember London-Frankfurt-Rome-Istanbul --- Delhi-Singapore-Darwin-Brisbane but I'm sure there should be something between Istanbul and Delhi.
For the nostalgia buffs, and if it helps, the date in question was 21st October 1964 and the aircraft was G-APDF. It was, from memory, the first wet leased BOAC/QANTAS charter to fly LDN - BNE
