With regard to all the "simulator babble" over on Jeff Wise and Duncan Steel, I find it interesting,  (perhaps by design ?)  that the suggested simulator great circle track from the FMT at Ache to McMurdo Sound-Mt Erebus (which is 5,500 nautical miles or 10,200 kilometres) just happens, (purely by chance mind) to intersect the 7th Arc at the same point ( 25deg 30min South 101deg 40min East ) as the direct path between the Inmarsat 3F-1 sub Satellite Point, and the Perth GES.
Too much of a coincidence ?
Curious, indeed.

The Light Blue arc is the 7th Arc
The Yellow line out of perth goes to the sub-satellite point
The Red line is the great circle track from the FMT to McMurdo
