Australia is Moving

Australia's adjusted national GPS coordinates  were recalculated and adjusted to keep pace with changing navigation technology. The continent moves north by seven centimeters (2.76 inches) every year due to its position on the world's fastest moving continental tectonic plate, according to Geoscience Australia. The country's coordinates were off by 1.5 meters (4.9 feet) due to years of natural shifting.

Satellite navigation systems on smartphones align with digital map information and autonomous vehicles could show you are in the middle of the road or you are in another lane. The Geocentric Datum of Australia, the nation's local coordinate system, was last updated during 1994.

Incidentally, the Indian Subcontinent in the past was moving towards Asia at a speed of about 6 inches per year. When they collided, the Himalayas came into being. They are still growing, but since then, India is only pushing into Asia proper at about 2 inches per year.
