Mel_Traveller, good spot. Its my ageing brain and it was 140k. And to be honest, the trip was 1.5 weeks ago and I'm not sure I have got over it. far, far too old for that sort of thing.....
As to the other, I always had the impression it was easier to snag J out of Sydney to Europe, the states etc. From what you say, not true? Purely an impression on my behalf, no research at all, so I am sure you are right. A bad move for us hands down then. Time to burn more miles.
MEL_Traveller is having a go at Qantas, which has a rather iffy award engine, which can spit out options with domestic connections onto longer flights, where the longer flight is in Y but the shorter domestic is in J, and of course due to the rules your entire itinerary is priced up in J.
Naturally, when US moves to AA, such silliness doesn't happen with AA (unless you are silly enough to book it).
Going to Europe, don't forget that whilst QF is an option (though getting QF J seats can be a challenge, especially at particular times), you have other options, e.g. BA (if you can put up with paying fuel surcharges), CX, MH and QR (relatively soon). Not sure how easy availability would be on all of those, except for CX, which I hear is almost always available. EY, an AA but non-
oneworld partner, is also an idea.
North America / USA will
always be a challenge on the direct, especially with QF being the only direct option. It was challenging enough with US DM to get UA direct across the Pacific (not impossible, but certainly one of the most challenging), but US DM did allow you to route via Asia without an increase in the cost in points. The only consolation is that if you're happy to settle for J, you have some extra options via DFW.
Apart from Transpacific, I don't see why so many rail at QF for availability. They aren't a self-opening pinata like TG and OZ, and of course in F it is a dead-set challenge, but for J, it isn't completely unreasonable. It can be quite a game, however, with availability changing at random times (seats released for no reason, even though found not be there before), but I managed to book DFW/BNE in J within 30 days of departure, with a bit of latitude of date choice to boot. It is far easier to book QF J long haul than it is to book NZ J long haul!
