The title is a little misleading. Australia isn't moving THAT fast, but it moves enough that we will need to adjust the waypoint coordinates for the missed approach waypoint on WAAS approaches from time to time. One of my students, for whom I recently did a BFR and IPC, is a bit of curmudgeon and a total GPS-hater. If he were here, he'd remind us all that no corrections are needed for VORs, because they move with the earth. Indeed they do. And if you only need to get within a mile of the airport, VORs work great.
