QFA2904 YSSY to Antarctica

I don’t think that is the root of the problem.

I asked a similar question last year Why does Estimated track not follow the lodged Flight Plan route

One day I’ll work out why Skyvector can decode the Flightplan coming in to Australia but Flightaware cannot.

It seem Flightaware can decode all the waypoints on US flights but have no knowledge of waypoints in other, non-US, FIR (Flight Information Region)
