I am finding the same with CX redemptions - I am looking at AKL/HKG but I only get AKL/XXX/HKG with XXX a point in Oz. According to both BA and JL there is plenty of J availability on the direct CX AKL/HKG flights, but nothing on QF.
I can't help but feel that there is something weird about QF award availability at the moment.
