On New Year’s Day 2020, New South Wales and Victoria jumped north by 5.9 feet. No, you did not miss an earthquake. The change is being made to fix a 5.9 foot inaccuracy that has crept into the GPS coordinates, caused by Australia slowly drifting north. Australian GPS was last updated in 1994, and the entire country has moved nearly six feet since then.

Australia sits atop one of the fastest-moving tectonic plates in the world. It moves about 2.5 inches north-east every year. “That’s about the speed your hair or fingernails grow,” says NSW Surveyor General Narelle Underwood.

In the days of paper maps that tectonic drift did not pose a real problem. That meant Australia could get away with the slight inaccuracy that has crept in since the coordinates were last set in 1994. But paper maps have gone the way of the dinosaurs; we use GPS now. And GPS notices. That's because GPS satellites precisely locate you on the surface of the Earth. Effectively the coordinate you have from your GPS has already moved 5.9 feet.

Add in the inaccuracy of GPS itself – it is accurate to about 16 feet – and that explains why you can sometimes open Google Maps and discover yourself trapped inside a building or drowning in a lake.

The project is handy for the average person, but its real value is in the future. Driverless cars, for example, need precise GPS data to know which lane they are in, and driverless tractors need to be able to get right up to the fence line without plowing it down.

Possible Preaching Angle:
Everything on earth changes, including the mighty continents. But for believers there are three crucial foundational things that will never change: God doesn't change, His Word doesn't change, and His promises do not change. These are settled forever in the heavens.
