In your example though you've got Amadeus - Sabre and back to Amadeus.
If it's just Amadeus - Sabre (or vice versa), in my experience you only get the first (or last) Sabre flight on Amadeus.
This!
The way the QF website works is also a mystery - some oneworld airlines, your booking will appear automatically if you add your FF number to that airlines booking - for example - any BA booking containing your QFF number will automatically show up, without having to add it to QF (and not a single QF flight is needed).
I've got an AA booking including a BA codeshare (JNB-LHR-SEA) and while the booking is viewable on BA, it doesn't show up on QF. The BA flight shows on (the old) CMT, but the AA flight doesn't.
This is why you need something like TripIt that will work across all systems.
