Yes. Each of those are only one ways. The SYD-LHR's are ticketed as through flights.
It looks like, on QF, the 2 BA longhauls add up to 560. Add the QF segs for 80= 640. Still 60 short, but pretty darn close.
Looks like thoses flights collecting with BA will get me close with 500 tier points.
LA, CX, and the others are still a puzzle to me
