That is a sort of a semi-cabotage to pick up and drop off in the same foreign country (not sure what degree of freedom this one is). You'd have to go JFK-LAX-Australia or v-v on QF if you use that.

There are not many other flights do that. The only other one to come to mind is BA SAN-PHX-LGW

Of course there are many codeshares.
