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.

This is important because GPS works out your location by calculating where you aren't.
Once it has where you aren't sorted out you must be where you are.
If, due to errors where you aren't now becomes where you are then the GPS system is no longer accurate.
Given that the new datum is calculated for 2020 then you won't be where you think you are for another 3 and 1/2 years

1.5 metres north. that is a lot of acreage moving from the Southern Mid latitude Air Circulation cell to the dry area between it and Southern Hadley Air Circulation Cell.
Boom! there is our climate change solved right there, unless of course the grid lines aren't there yet?

Does this mean that Victoria is going to get a little bit warmer?

I heard this morning that Australia is moving 7cms north and 11cms west per year.

Still doesn't get me any closer to Cape York.

That would explain why I couldnt find my socket set
it was exactly 1.5mtrs from where I used it last

Did Tasmania move as well or did we leave them in the past.?
If so do the fares on the farries and flights go up?
Should the airfares to all countries north decrease?
Should the government "stop the boats" 1.5 mtrs sooner?
These questions need answers.

It was because of us that you're moving... you're too close and we don't like it.

I looked over my back fence at my neighbours pool and worked out with the 1.5 meter shift it is now partly on my land so I can start using it now, will only be able to shuffle along a narrow section on one edge though.

That explains why my eyesight is getting crappier each year and why I have to hold things further away to read them ... or have I got that back to front?

WA would be the new eastern states and the eastern states be WA.

W.A. actually already is. Why you ask?

Well, that is because when you use a Compass, the North end of the needle points South.
Therefore West has always in reality been East

Just think in 2040 you'll have 1.5m worth of pool....
