SYDNEY, Australia — That map of Australia you have? It’s wrong. And the whole country is going to officially relocate to correct the error.

The trouble is caused by plate tectonics, the shifting of big chunks of the earth’s surface. Australia happens to be on one of the fastest-moving pieces of all, and by geological standards it’s practically flying: about 2.7 inches northward a year, with a slight clockwise rotation as well.

People on the ground may not notice, but the Global Positioning System does. So Australia needs to adjust its longitudes and latitudes so they line up with GPS coordinates.

Four times in the last 50 years, Australia has reset the official coordinates of everything in the country to make them more accurate, correcting for other sources of error as well as continental drift. The last adjustment, in 1994, was a doozy: about 656 feet, enough to give the delivery driver an alibi for ringing your neighbor’s doorbell instead of yours.
