What the aircraft actually flies over
From Sydney the path crosses Australia, then 1,032 km of open water, then Australia.
The furthest the great circle gets from the equator is 34.4°S, 30% of the way along.
Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.
Leaving Sydney the aircraft points west (264°); it arrives into Perth heading west (284°). That is 20° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
