The JT9's are -7R's and are only on the -200's. The CF6's are on the -300's. At the time the 767-300ER's were ordered, there was no suitable P&W engine as far as QF was concerned. They were going to need a new engine in the inventory anyway. The JT9's weren't big enough for the -300's, the RB211-524H wasn't being delivered, and neither were the PAW4000's. RR had only one customer (I think it still does, BA). In short the CF6 was the only proven engine at the time of order. Given the QF route structure, it doesn't pay for them to operate aircraft with unusual configurations. They can be very hard to get fixed at remote stations. If you use commonly used and available engines, there is likely to be a pooled spare or expertise and parts in most places. My recollections anyway. I suspect GE helped things along by making QF a repair station for CF6's. The 767-300ER's are QANTAS's only GE powered aircraft. (Yes they now some A300 with CF6 and CFM56 as a result of Australian Airlines merger).
