Unless I'm mistaken the thread you cite...
Point taken on the first one. Sounds like it's YMMV. The citation was for the sake of the LAX-JFK rules, not the QC/AC/FL access rules.
And if you just want extra tier points, and have the flight coupons, you could always fly AKL-SYD/BNE/MEL-LAX-JFK, just making sure to avoid QF107 from SYD-LAX. That's even better for tier points than AKL-LAX-JFK.
