Oh, my friend, you've done it. That is magnificent.
Were you around here when you started? The ocean might return in 2000 years so southwest wouldn't be an option no matter what the compass said. I'd be interested if there had been an actual polar swap of if it was just an oscillation. You will have to stick around a while to find out I guess.
He did try to find a safe spot to park, just in case of sea level rise. Inconclusive if there was a pole swap, or if Australia made a jump northward like India did a real long time ago, and twisted a little bit throwing the compass needle off.
I'd guess those two conditions would be hard to diagnose from 'on the ground'.
