I see to recall that Australia is on the move. So it would seem that we should retain as much accuracy as possible then if we're a metre out it isn't quite so important.<br>
<br>
I think any generic addressing scheme is going to suffer from parts of the world moving though and it is a limitation we have to work with. From a practical point of view just grabbing a new address every decade would probably work fairly well.<br>

I wish an address could be more stable than a decade, as it should be used also in property documents. If it is 2 - 5 meters per century, then it is still acceptable.<br>

I wonder how "three words" services plan to deal with it? Recalculating coordinates behind the scene? But in a century there will be probably no these services, and no Internet as we know it. It is a lot of time. But latitude and longitude will still exist. And it would be possible to recalculate them taking into account the tectonic plates factual movement to prove property rights.<br>
