Due to tectonic shifts, the entire continent of Australia has moved 1.5 metres north over the past 22 years, putting it out of sync with global positioning systems (GPS).
To fix the problem, the government's announced that the country's latitude and longitude will officially be updated to reflect the continent's new position.
But for Australia, those coordinates were last updated by the national body - the Geocentric Datum of Australia (GDA) - in 1994, and since then, the continent's moved more 1.5 metres.
